Blast and bacterial blight (BB) pose a significant threat to rice production. To enhance resistance to blast and BB, we employed marker-assisted backcross breeding to introgress the resistance genes into the genetic background of BRRI dhan48. The resistant (R) genes Pi9, Pb1, Xa4, xa13, and Xa21 were introgressed from Pi9-US2, Pb1-US2, and IRBB58, respectively. The Pb1 gene strengthens blast resistance in rice by interacting with WRKY45 transcription factor to modulate salicylic acid and phytoalexin pathways, while the Pi9 gene triggers a signaling cascade involving reactive oxygen species (ROS) production and hormones like jasmonic acid and ethylene activation to enhance defense responses. Xa4 strengthens the cell wall via WAK (cell wall-associated kinase) protein, hindering pathogen invasion, xa13 disrupts SWEET (Sugar Will Eventually be Exported Transporter) protein function to limit sugar availability for Xanthomonas oryzae pv. oryzae (Xoo). Xa21 triggers mitogen-activated protein kinases (MAPKs)-mediated signaling cascades, leading to the activation of WRKY transcription factors that suppress bacterial proliferation. For that, triple cross was made, followed by repeated backcrosses, self-pollinations, and marker-assisted selection to generate BC3F5 progeny. Chi-square analysis of 380 BC3F2 individuals confirmed a monogenic inheritance pattern for blast and BB resistance traits. Finally, we selected 32 advanced lines, and among them nineteen lines possessed all these 5 R genes, i.e., Pi9, Pb1, Xa4, xa13, and Xa21, while eight lines consisted of 4 R genes in different combinations. The disease rating of the advanced lines varied from 0 to 5 for both blast and BB diseases, while BRRI dhan48 had a disease rating ranging from 7 to 9. The lines G10, G25, G16, G31, G9, G2, and G20 demonstrated significantly higher grain yield (7.73, 7.72, 7.70, 7.65, 7.64, 7.59, and 7.58 t ha−1, respectively) than the parent (7.00 t ha−1). Investigation of marker trait association showed that molecular markers were negatively linked with blast and BB diseases. So, gene introgression by marker-assisted backcrossing (MABB) offers a robust and efficient way to identify and validate candidate genes with high precision for the development of durable, resistant rice breeding lines. These multiple disease resistant advanced lines may use as a potential genetic stock or incorporate with other desired genes for ensuring sustainable rice production under changing climatic conditions.
稻瘟病和细菌性枯萎病(BB)对水稻生产构成重大威胁。为了增强对稻瘟病和细菌性白叶枯病的抗性,我们采用了标记辅助回交育种方法,将抗性基因导入 BRRI dhan48 的遗传背景中。抗性(R)基因 Pi9、Pb1、Xa4、xa13 和 Xa21 分别从 Pi9-US2、Pb1-US2 和 IRBB58 中导入。Pb1 基因通过与 WRKY45 转录因子相互作用来调节水杨酸和植物毒素途径,从而增强水稻的抗稻瘟病能力;而 Pi9 基因则触发了一个信号级联,涉及活性氧(ROS)的产生以及茉莉酸和乙烯等激素的激活,从而增强防御反应。Xa4 通过 WAK(细胞壁相关激酶)蛋白强化细胞壁,阻碍病原体入侵;xa13 破坏 SWEET(糖最终将被输出转运体)蛋白功能,限制黄单胞菌(Xanthomonas oryzae pv. oryzae,Xoo)的糖供应。Xa21 触发有丝分裂原激活蛋白激酶(MAPKs)介导的信号级联,从而激活抑制细菌增殖的 WRKY 转录因子。为此,研究人员进行了三系杂交,然后反复进行回交、自花授粉和标记辅助选择,以产生 BC3F5 后代。对380个BC3F2个体的卡方分析证实了抗瘟和抗BB性状的单基因遗传模式。最后,我们选育出 32 个先进品系,其中 19 个品系拥有全部 5 个 R 基因,即 Pi9、Pb1、Xa4、xa13 和 Xa21,8 个品系由不同组合的 4 个 R 基因组成。先进品系的稻瘟病和 BB 病的病害等级从 0 到 5 不等,而 BRRI dhan48 的病害等级从 7 到 9 不等。品系 G10、G25、G16、G31、G9、G2 和 G20 的粮食产量(分别为 7.73 吨/公顷、7.72 吨/公顷、7.70 吨/公顷、7.65 吨/公顷、7.64 吨/公顷、7.59 吨/公顷和 7.58 吨/公顷)明显高于母本(7.00 吨/公顷)。标记性状关联调查表明,分子标记与稻瘟病和 BB 病呈负相关。因此,通过标记辅助回交(MABB)进行基因导入,为高精度鉴定和验证候选基因提供了一种稳健而有效的方法,可用于培育持久抗病的水稻育种品系。这些具有多重抗病性的先进品系可作为潜在的基因储备,或与其他所需基因结合,以确保在不断变化的气候条件下实现水稻的可持续生产。

Baccaurea ramiflora Lour. (Burmese grape), a wild fruit tree with edible, ornamental, and medicinal qualities. The mechanism behind the color accumulation in its fruit pulp, which can be either pink or milky-white, remains unclear. This study investigates the metabolome and transcriptome of two B. ramiflora pulp types—LR (milky-white at maturity) and BR (pink at maturity)—to elucidate their coloration processes. We identified 35 flavonoids, including nine involved in the anthocyanin synthesis pathway, confirming cyanidin as the pivotal pigment for the pink pulp coloration. An examination of the flavonoid and anthocyanin biosynthetic pathways in B. ramiflora pulp uncovered 39 differentially expressed genes associated with structural genes. The genes F3′5′H and UFGT exhibited high expression levels in the first two developmental stages of BR, significantly more than in LR, and were almost non-existent in later stages, signifying their crucial role in the differential color accumulation between BR and LR pulps. Additionally, the expression levels of CHI and FLS, early-stage structural genes in the anthocyanin synthesis pathway, correlated with the concentrations of naringenin and quercetin, indicating their importance in the anthocyanin biosynthesis pathway of B. ramiflora pulp. These discoveries provide new insights that could facilitate the breeding of B. ramiflora varieties with diverse pulp colors.
假芽孢杆菌。(缅甸葡萄),一种可食用、观赏和药用的野生果树。其果肉可能是粉红色的,也可能是乳白色的,其颜色积累背后的机制尚不清楚。本研究研究了两种不同果肉类型(成熟乳白色和成熟粉红色)的代谢组学和转录组学,以阐明它们的着色过程。我们鉴定了35种黄酮类化合物,其中9种参与花青素合成途径,证实了花青素是粉红果肉着色的关键色素。通过对芥蓝果肉类黄酮和花青素生物合成途径的研究,发现了39个与结构基因相关的差异表达基因。F3’5’h和UFGT基因在BR发育的前两个阶段表达水平较高,显著高于LR,而在后期几乎不表达,说明它们在BR和LR果肉颜色积累差异中起着至关重要的作用。此外,花青素合成途径的早期结构基因CHI和FLS的表达水平与柚皮素和槲皮素的浓度相关,说明它们在花青素合成途径中的重要性。这些发现为培育具有不同果肉颜色的分枝芽孢杆菌品种提供了新的思路。

Flowering is a critical plant growth stage coordinated by internal and external factors. Changes to endogenous sugar levels can promote or inhibit flowering, but research on the regulation of flowering-related genes associated with the sugar pathway in cotton is limited. Here, a genome-wide study identified 165 flowering and sugar pathway-related genes in five cotton species: Gossypium herbaceum, G. arboreum, G. hirsutum, G. barbadense, and G. raimondii. The genes were phylogenetically classified into nine subfamilies and showed a high degree of conservation. Notably, no homologs of INDETERMINATE DOMAIN 8 (IDD8), SUCROSE-PROTON SYMPORTER 9 (SUC9), or AGP GALACTOSYLTRANSFERASE 2 (GALT2) were identified. A synteny analysis provided evidence of varying degrees of gene expansion, and a selection pressure analysis indicated that the genes had undergone purifying selection, with Ka/Ks ratios of <1. The similarity among the genes identified in G. herbaceum, G. arboreum, and G. raimondii was higher than between these species and the allopolyploid cotton species, indicating the earlier divergence of these genes. A network analysis of protein interaction revealed G. hirsutum proteins to be associated primarily with sugar synthesis, transport, and metabolism. Yeast two-hybrid assays demonstrated that GhTPS1–1 and GhHXK1–1 can interact with GhPGI1–1. RNA-sequencing data for 46 genes from eight tissue-types in G. hirsutum revealed that most were highly expressed in stems and flowers. This study provides a comprehensive phylogenetic and network analysis of flowering-related genes in the sugar pathway across five Gossypium species, laying a foundation for future in-depth research on the functional mechanisms of these genes.
开花期是植物生长发育的关键阶段,内外因素相互协调。内源糖水平的变化可以促进或抑制棉花的开花,但对棉花中糖途径相关的开花相关基因调控的研究有限。在这里,一项全基因组研究鉴定了5种棉花的165个开花和糖通路相关基因:棉花、树棉、毛棉、巴贝登棉和雷蒙地棉。这些基因在系统发育上被划分为9个亚科,并表现出高度的保守性。值得注意的是,未发现INDETERMINATE DOMAIN 8 (IDD8)、蔗糖-质子同体转运酶9 (SUC9)或AGP半乳糖转移酶2 (GALT2)的同源物。合成分析表明基因扩增程度不同,选择压力分析表明基因进行了纯化选择,Ka/Ks比值为<;1。草本棉种、乔木棉种和雷蒙棉种的基因相似性高于异源多倍体棉种,表明这些基因的分化时间较早。蛋白质相互作用的网络分析表明,毛藓蛋白主要与糖的合成、运输和代谢有关。酵母双杂交实验表明GhTPS1-1和GhHXK1-1可以与GhPGI1-1相互作用。对来自8种组织类型的46个基因的rna测序数据显示,大多数基因在茎和花中高表达。本研究对5种棉属植物糖通路中开花相关基因进行了全面的系统发育和网络分析,为进一步深入研究这些基因的功能机制奠定基础。

Novel genetic control of alpha-amylase activity during pre-harvest sprouting indicated by RNA sequencing of soft winter wheat varieties Cardinal and Logan 软质冬小麦品种红衣主教和洛根收获前发芽α -淀粉酶活性的新遗传控制
IF 2.2 Q3 GENETICS & HEREDITY Pub Date : 2025-06-01 Epub Date: 2025-02-28 DOI: 10.1016/j.plgene.2025.100495

Pre-harvest sprouting, the germination of wheat seeds still in the field, leads to decreased crop value and increased crop losses around the world. Pre-harvest sprouting causes low Falling Number that results in price reductions or rejection of soft winter wheat grain at the flour mill or grain elevator. Several pre-harvest sprouting resistance genes have been found. However, they act through seed dormancy-related signaling pathways which can affect winter wheat root establishment for overwintering and double-cropping wheat with soybean. Here, RNA sequencing has been performed on soft red winter wheat varieties Cardinal and Logan with 91 % of 1978 markers common between them but differing in pre-harvest sprouting resistance. Between 64 and 660 genes were differentially expressed in comparisons between Cardinal and Logan at different time points of seed development. A glucan water diskinase was a top five differentially expressed gene located near a recently reported quantitative trait locus for pre-harvest sprouting. It has potential to reduce alpha amylase activity and starch degradation during pre-harvest sprouting. Slowing starch degradation reduces starch damage, keeping flour pasting viscosity and Falling Number higher under pre-harvest sprouting conditions. Slowing starch damage rather than altering seed dormancy would reduce impact on some agronomic traits.
收获前发芽,即小麦种子仍在田间发芽,导致世界各地作物价值下降和作物损失增加。收获前发芽导致低下降数,导致价格下降或在面粉厂或谷物升降机拒收软冬小麦。已经发现了几个收获前发芽抗性基因。但它们通过与种子休眠相关的信号通路起作用,影响冬小麦越冬和双季小麦与大豆的根系建立。本文对软红冬小麦品种红衣主教和洛根进行了RNA测序,发现1978年91%的标记是相同的,但在收获前发芽抗性方面存在差异。红衣主教和洛根在种子发育的不同时间点上有64 ~ 660个基因的差异表达。一个葡聚糖水盘激酶是位于最近报道的收获前发芽数量性状位点附近的前5个差异表达基因。它有可能降低α淀粉酶活性和淀粉降解在收获前发芽。在采前发芽条件下,减缓淀粉降解可减少淀粉损伤,保持面粉黏度和落数较高。减缓淀粉损害而不是改变种子休眠将减少对某些农艺性状的影响。

As one of the most important agronomic traits of the tea plant (Camellia sinensis), the timing of bud flush (TBF) affects the sales price of tea beverages. Here, we performed specific-locus amplified fragment (SLAF) sequencing and genome-wide association study (GWAS) analysis on 200 offspring of natural hybridization from the ‘Qianmei 601’. A total of 796,294 SLAF tags and 2,324,211 single-nucleotide polymorphisms (SNPs) were obtained by sequencing. The 200 tea germplasms were clustered into four groups by population structure, principal component analysis (PCA) and phylogenetic tree analysis. GWAS identified twelve SNPs loci that were significantly associated with TBF traits. Seven candidate genes associated with TBF were subsequently identified by scanning in the regions within 1 Mb SNP loci. In addition, we found that two candidate genes (ARP and WRKY) were highly expressed in individuals with early TBF. Interestingly, cloning and sequencing of the ARP gene revealed C-G variants between the early and late TBF individuals.

作为茶树(Camellia sinensis)最重要的农艺性状之一,花蕾开花时间(TBF)影响着茶饮料的销售价格。本研究对“前美601”自然杂交的200个后代进行了SLAF测序和全基因组关联分析(GWAS)。测序共获得796,294个SLAF标签和2,324,211个单核苷酸多态性(snp)。通过群体结构分析、主成分分析和系统发育树分析,将200份茶叶种质资源聚为4个类群。GWAS鉴定出12个与TBF性状显著相关的snp位点。随后,通过扫描1个 Mb SNP位点内的区域,确定了7个与TBF相关的候选基因。此外,我们发现两个候选基因(ARP和WRKY)在早期TBF个体中高表达。有趣的是,ARP基因的克隆和测序显示,早期和晚期TBF个体之间存在C-G变异。研究结果为茶树TBF的早期选育和功能基因分析提供了理论依据。

Genus Senna (Caesalpinioideae, Fabaceae) comprises about 350 species mainly distributed in the American continent. Despite the sequencing and assembly of the chloroplast genome of some of the species in the genus, the chloroplast genome sequence and structural variation have not been evaluated, and the evolutionary relationship within the genus is still lacking. In this study, we sampled different species of the genus representing the six sections to examine the variation in the genome and phylogenetic relationships. The chloroplast genome of Senna has a typical quadripartite structure with a size ranging from 148, 437 bp to 162, 426 bp. There are gene losses in some species of the genus, the earliest diverged species lost 9 protein-coding genes which were recovered in the latter diverged lineages. No inversion was detected in the genome but there is a significant level of sequence variation, gene number, and genome size, that provide valuable information on the evolution of the genus. The following regions are the most variable regions in the genus and can be used as DNA barcodes for the identification of the species: Psba, ndhH, trnT-trnL, trnG-trnR, rps18-rpl20, and trnI-rrn16. The phylogenomic analysis revealed a well-resolved phylogenetic relationship of the genus, supporting the monophyly of the genus. The phylogenetic tree reported the phylogenetic positions and sister relationships of some species for the first time. Our result revealed that section Chameafistula is paraphyletic and calls for the revision of the infrageneric classification of the genus.
番泻属(番泻科,番泻科)约350种,主要分布于美洲大陆。尽管对属中部分物种的叶绿体基因组进行了测序和组装,但叶绿体基因组序列和结构变异尚未得到评价,属内的进化关系仍然缺乏。在这项研究中,我们取样了代表六个部分的属的不同物种来研究基因组的变异和系统发育关系。塞纳叶绿体基因组具有典型的四分体结构,大小在148,437 ~ 162,426 bp之间。部分种存在基因丢失现象,最早分化的种丢失了9个蛋白质编码基因,这些基因在后期分化谱系中得到了恢复。在基因组中没有检测到反转,但有显著水平的序列变异,基因数量和基因组大小,为属的进化提供了有价值的信息。以下区域是属中变异最大的区域,可作为物种鉴定的DNA条形码:Psba、ndhH、trnT-trnL、trnt - trnr、rps18-rpl20和trnI-rrn16。系统发育分析显示,该属的系统发育关系得到了很好的解决,支持该属的单系性。系统发育树首次报道了部分物种的系统发育位置和亲缘关系。我们的研究结果表明,Chameafistula属是副属,并要求修订该属的下属分类。

Deciphering the complete CDS sequence of Bibenzyl synthase (BBS) gene in Pholidota articulata and its transcriptional regulation under different stress conditions 解读海螺联苯合成酶(BBS)基因CDS全序列及其在不同胁迫条件下的转录调控
IF 2.2 Q3 GENETICS & HEREDITY Pub Date : 2025-03-01 Epub Date: 2025-01-08 DOI: 10.1016/j.plgene.2025.100491

Bibenzyl synthase (BBS) is one of the key enzymes for the formation of bibenzyls, a class of specialized therapeutic metabolites that are predominantly found in the family Orchidaceae. The present study reports the complete transcript of the BBS gene isolated and sequenced from an ethnomedicinally important orchid, Pholidota articulata Lindl. The BBS transcript of P. articulata (PaBBS) was found to comprise a total of 1494 bp with an open reading frame coding for 390 amino acids. Multiple sequence analysis and phylogenetic analysis highlighted its close association with BBS sequences and type III polyketide synthase (PKS III) genes of other plant species. Three-dimensional structure analysis has revealed that the PaBBS protein is a homodimer with each subunit having a molecular weight of 42.83 KDa. In silico studies of the putative PaBBS protein revealed the presence of the characteristic conserved regions of the BBS enzyme as well as the PKS III superfamily. The present study also revealed that expression PaBBS is influenced by the age of the plant, tissue type, abiotic stress, and exposure to elicitors. The expression of PaBBS transcript was recorded to be higher in young plantlets as compared to mature plants, and among the plant parts the root tissue exhibited the highest expression. Further, it was found that the expression of PaBBS was upregulated by abiotic stresses such as wounding and heat treatment, downregulated by high-intensity UV exposure and cold treatment, and increased many-fold when exposed to elicitors like chitosan and yeast extract. The results obtained in the present study provide an understanding of the transcriptional regulation of PaBBS gene which plays a crucial role in the ecological adaptation of P. articulata, an orchid of medicinal importance.
联苯合成酶(Bibenzyl synthase, BBS)是形成联苯的关键酶之一,联苯是一类主要存在于兰科植物中的特殊治疗代谢产物。本研究报道了从一种民族医学上重要的兰花Pholidota articulata Lindl中分离和测序的BBS基因的完整转录本。P. articulata (PaBBS)的BBS转录本全长1494 bp,包含一个开放阅读框,编码390个氨基酸。多序列分析和系统发育分析显示其与其他植物的BBS序列和III型聚酮合成酶(PKS III)基因密切相关。三维结构分析表明,该蛋白为同二聚体,每个亚基分子量为42.83 KDa。对假定的PaBBS蛋白的计算机研究揭示了BBS酶的特征保守区域以及PKS III超家族的存在。本研究还发现,PaBBS的表达受植物年龄、组织类型、非生物胁迫和暴露于激发子的影响。与成熟植株相比,幼嫩植株中PaBBS转录本的表达量更高,而在植株各部位中,根组织的表达量最高。此外,我们还发现,在损伤和热处理等非生物胁迫下,PaBBS的表达上调,在高强度紫外线照射和低温处理下,PaBBS的表达下调,而在壳聚糖和酵母提取物等激发剂作用下,PaBBS的表达增加了许多倍。本研究结果为了解药用兰科植物P. articulata在生态适应中起重要作用的PaBBS基因的转录调控提供了依据。

Phylogenetic patterns of understudied species within the plant genus Brassica: Future prospects in the post genomics-era 芸苔属植物中未被充分研究的物种的系统发育模式:后基因组时代的未来展望
IF 2.2 Q3 GENETICS & HEREDITY Pub Date : 2025-03-01 Epub Date: 2024-12-27 DOI: 10.1016/j.plgene.2024.100489

Brassica remains to be one of the agriculturally important genera of plants worldwide due to its diverse nature of crops cultivated all across the globe. Despite the rich species diversity within the genus Brassica, detailed studies on phylogeny and evolutionary origins have primarily focused on just six species, which have given rise to nearly all of the currently cultivated Brassica crops. Continuous breeding practices for specific traits in these six species have led to significant challenges, including nutrient depletion, increased susceptibility to plant pathogens, and vulnerability to changing climate conditions in the present generation of crops. Lack of established phylogenetic relationships among the species of Brassica remains to be a significant barrier hindering error-free conservation and use of Brassica resources. We have identified putative phylogenetic relationships between Brassica crop wild relatives (CWRs) by reinforcing data from several genetic markers and metabolite based studies. Supplementation of genomic data for a robust phylogeny and current status of availability of genomic data of Brassica crop wild relatives (CWRs) from public database has been highlighted. This report identifies critical gaps in Brassica research addressing of which would facilitate effective conservation and use of Brassica genetic resources.
由于其在全球范围内种植的作物的多样性,芸苔属仍然是世界范围内重要的农业植物属之一。尽管芸苔属植物具有丰富的物种多样性,但对其系统发育和进化起源的详细研究主要集中在6个物种上,而这6个物种几乎产生了目前栽培的所有芸苔属作物。对这六种作物的特定性状进行持续育种已经带来了重大挑战,包括营养枯竭、对植物病原体的易感性增加以及对当前一代作物气候条件变化的脆弱性。油菜种间系统发育关系的缺乏是阻碍油菜资源无偏保护和利用的重要障碍。我们通过加强来自几个遗传标记和基于代谢物的研究数据,确定了油菜作物野生近缘(CWRs)之间假定的系统发育关系。强调了基因组数据的补充和公共数据库中芸苔属作物野生近缘(CWRs)基因组数据的现状。本报告确定了芸苔属植物研究的关键空白,解决这些空白将促进芸苔属植物遗传资源的有效保护和利用。

Saffron corms transcriptome analysis reveals genes associated with corm rot disease 藏红花球茎转录组分析揭示了与球茎腐病相关的基因
IF 2.2 Q3 GENETICS & HEREDITY Pub Date : 2025-03-01 Epub Date: 2024-12-20 DOI: 10.1016/j.plgene.2024.100488

Saffron (Crocus sativus L.) is by far the most expensive spice in the world. Low water requirements, straightforward agricultural practices, diverse applications in the food, pharmaceutical and textile industries, are major advantages for its widely cultivation worldwide. Saffron is genetically sterile and hence it is propagated through corms. As a perennial plant, its corms remain in the field for at least three consecutive cultivation seasons, increasing their susceptibility to soilborne pathogens. Among devastating soilborne plant pathogens, Fusarium oxysporum f. sp., the causal agent of corm rot, poses a significant threat to saffron cultivation globally. The development of effective management strategies against F. oxysporum is impeded by the absence of resistant genotypes and a limited understanding of its pathogenicity. To assess and find genes associated with the response to F. oxysporum infection, the corm transcriptome was analyzed following F. oxysporum inoculation by RNA-seq. More than 294,520 and 243,328 transcripts were documented. Out of 168,448 identified unigenes, 34,862, 15,234 and 27,213 unigenes were annotated in NCBI non-redundant (Nr) protein database, GO and UniProtKB/Swiss-Prot databases, respectively. Out of 38,643 annotated genes, 2169 genes exhibited differential expression in response to F. oxysporum. Among these, 1832 genes showed decreased expression, whereases 337 genes displayed increased expression. Quantitative RT-PCR analysis confirmed the expression patterns of 10 hub genes, including chitinase, a serine/threonine kinase and a WRKY transcription factor gene. In contrast, the relative expression of a pectin methylesterase, a Flavodoxin-like quinone oxidoreductase and HSP genes were found to be down-regulated. The findings of this study clearly demonstrate that F. oxysporum infection significantly perturbs the expression of corms R-genes, suggesting that such genes can be used to improve saffron plant resistance to fungal and oomycetes soilborne pathogens in future breeding programs.
藏红花(Crocus sativus L.)是目前世界上最昂贵的香料。低需水量,简单的农业实践,在食品,制药和纺织工业中的多种应用,是其在全球广泛种植的主要优势。藏红花是遗传不育的,因此它是通过球茎繁殖的。作为一种多年生植物,它的球茎至少连续三个栽培季节留在田间,增加了它们对土传病原体的敏感性。在破坏性的土传植物病原体中,导致玉米腐烂的镰刀菌(Fusarium oxysporum f. sp.)对全球藏红花种植构成重大威胁。由于缺乏耐药基因型和对其致病性的了解有限,阻碍了对尖孢镰刀菌有效管理策略的发展。为了评估和发现与尖孢镰刀菌感染应答相关的基因,采用RNA-seq方法分析了接种尖孢镰刀菌后球茎的转录组。记录笔录294520余份、243328份。在鉴定的168,448个unigenes中,分别有34,862个、15,234个和27,213个unigenes在NCBI非冗余(Nr)蛋白数据库、GO和UniProtKB/Swiss-Prot数据库中被注释。在38643个被注释的基因中,2169个基因对尖孢镰刀菌表现出差异表达。其中表达减少的基因有1832个,表达增加的基因有337个。定量RT-PCR分析证实了10个枢纽基因的表达模式,包括几丁质酶、丝氨酸/苏氨酸激酶和WRKY转录因子基因。相反,果胶甲基酯酶、黄毒素样醌氧化还原酶和HSP基因的相对表达量被发现下调。本研究结果清楚地表明,尖孢镰刀菌感染显著干扰了球茎r基因的表达,这表明这些基因可以在未来的育种计划中用于提高藏红花植物对真菌和卵菌土传病原体的抗性。
