This study assessed the genetic and phenotypic variation of 12 �int maize inbred lines and performed association analysis of 11 drought-related traits using 360 simple sequence repeats (SSRs), detecting 1,604 alleles, with an average of 4.4 alleles per locus. The average values of gene diversity (GD) and polymorphism information content (PIC) were 0.648 and 0.598, respectively. In principal component analysis (PCA), shoot fresh weight (SFW), shoot dry weight (SDW), stem weight (SW), leaf weight (LW), root fresh weight (RFW), root dry weight (RDW), and leaf area (LA) traits contributed greatly to the PIC. Association analysis was performed using a general linear model with a Q-matrix (Q GLM) and a mixed linear model with Q and K-matrices (Q + K MLM). Twelve SSR markers for drought tolerance trait were detected by Q GLM, and all maize inbred lines were clearly divided into two groups in accordance with their drought tolerance. Duplicated signi�cant marker-trait associations (SMTAs) between Q GLM and Q + K MLM identi�ed eight marker-trait associations involving four SSR markers that were associated with the traits of SW, SFW, RFW, and RDW with a signi�cant level of P < 0.05. The umc1175 and umc2092 were associated with SW and SFW; umc1503 was associated with RFW, SFW, and SW; and umc2341 was associated with RDW. The detection of loci associated with drought-related traits in this study may provide better opportunities to improve maize drought tolerance by marker-assisted selection (MAS). These results will be useful for breeders in producing tolerant varieties as well as markers for using MAS in maize breeding programs.
本研究利用360个简单重复序列(SSRs)对12个玉米自交系的遗传和表型变异进行了评估,并对11个干旱相关性状进行了关联分析,共检测到1604个等位基因,平均每个位点检测到4.4个等位基因。基因多样性(GD)和多态性信息含量(PIC)的平均值分别为0.648和0.598。在主成分分析(PCA)中,地上部鲜重(SFW)、地上部干重(SDW)、茎重(SW)、叶重(LW)、根鲜重(RFW)、根干重(RDW)和叶面积(LA)等性状对PIC的影响较大。使用带有Q矩阵的一般线性模型(Q GLM)和带有Q和K矩阵的混合线性模型(Q + K MLM)进行关联分析。qglm检测到12个抗旱性状的SSR标记,根据玉米自交系的抗旱能力,将所有自交系明确分为两类。qglm和Q + K MLM之间的重复显著标记-性状关联(SMTAs)鉴定出与SW、SFW、RFW和RDW性状相关的4个SSR标记共8个,显著水平均为P < 0.05。umc1175和umc2092与SW和SFW相关;umc1503与RFW、SFW和SW相关;umc2341与RDW相关。本研究中与干旱相关性状相关的位点的检测可能为利用标记辅助选择(MAS)提高玉米抗旱性提供更好的机会。这些结果将有助于育种者培育出耐受性强的品种,以及在玉米育种计划中使用MAS的标记。

Powdery mildew (PM), caused by the biotrophic fungus Podosphaera xanthii, drastically reduces the yield and quality of melon (Cucumis melo L.). Knowledge on the genetic control and high throughput molecular markers linked with resistance against this disease are essential for breeding programs. The bioassay study of the F 1 and F 2 populations derived from the parents, ‘PMR 5’ ((cid:0)) and ‘SCNU1154’ ((cid:0)) revealed a monogenic dominant nature of resistance to the devastating race, race 5. Besides, we developed three SNP based high resolution melting markers, PMm-HRM-1, PMm-HRM-2, and PMm-HRM-3 based on the previously identi�ed SNPs on chromosome 12 and validated those using 10 melon lines and 137 F 2 population. Among these, the SNP of marker PMm-HRM-1 causes a missense mutation (Lysine → Glutamic acid) in the LRR region of MELO3C002393 and were able to distinguish the resistant vs susceptible genotypes from 10 diverse melon population and the segregating F 2 population with more than 90% genotyping e�ciency. Other two markers were based on intergenic SNPs and had more than 80% genotyping e�ciency F 2 population. These markers will be helpful to melon breeders to develop melon cultivars resistant to P. xanthii race 5 via marker assisted breeding programs. and 1 s at 97°C. HRM data was performed using LightCycler 96 software at 100% discrimination for delta Tm and curve shape with a 0.2 positive/negative threshold level.

Knowledge of productivity and genetic control of the rate of ultra-early lines development will facilitate their use in breeding of common wheat Tritium aestivum L. for high adaptive capacity. The research focused on ultra-early lines Rico (k-65588), Rimax (k-67257) (progeny of F3 Rico × ‘Max’, k-57181), Fori 1-8 line series (progeny of F4 ‘Photon’ × Rico) and Rifor 1-13 (progeny of F7-8 Rico × ‘Forlani Roberto’), as well as on the accessions ‘Photon’ (k-55696) and ‘Forlani Roberto’ (k-42641). The varieties ‘Leningradskaya 6’ (k-64900) and ‘Leningradskaya 97’ (k-62935) were used as standards in VIR, and ‘Chelyaba 2’ (k-64379) was used in Сhelyabinsk ARI. The alleles of Vrn and Ppd genes were identified by PCR using the published allele-specific primers. Responses to vernalization (30 days at 3°C) and to a short 12-hour day were determined according to the VIR guidelines. The ultra-earliness of common wheat lines is associated with the presence of dominant alleles Vrn-A1, Vrn-B1, Vrn-D1, Ppd-B1, Ppd-D1, and possibly Eps. The shortest emergence-to-heading period at two experimental locations was noted for Rico (39.9 ± 1.49 days), which is 14.8 ± 1.22 days earlier than the development of region-adapted varieties. The Rico genotype contains Vrn-A1, Vrn-B1, Vrn-D1, Ppd-B1 and Ppd-D1. In the Rimax genotype, different alleles of the Ppd-D1 and Vrn-B1 genes were found, possibly being a result of recombination processes in Rico × ‘Max’ hybrids. Under a short photoperiod (12 hours), the Rico and Rimax genes can interact in a cumulative polymeric mode, which is not the case in long-day environments. Unlike other Rifor lines, Rifor 4 and Rifor 5, as well as ‘Forlani Roberto’, have a recessive vrn-A1a allele. However, Rifor 4 and Rifor 5 do not respond to vernalization, while ‘Forlani Roberto’ is responsive to this factor. The absence of response to vernalization in Rifor 4 and Rifor 5 possessing the recessive vrn-A1a allele is possibly provided by a complex of modifier genes along with the dominant Vrn-D1 gene, which was formed during recombination in F7-8 Rico × ‘Forlani Roberto’ hybrids. Recombinants of spring common wheat, combining ultra-earliness and relatively high ear productivity, have been identified. Grain yield per 1 m2 of new ultra-early lines in some years can reach 90% of that of the ‘Leningradskaya 97’. It is expedient to use ultra-early lines as donors of high-rate development in common wheat breeding, considering genetic peculiarities of the source lines.

Agrobacterium is a natural genetic material delivery system that humans use to produce genetically modified plants (GMO). In nature, GMOs also occur with the participation of agrobacteria. In 2019, the list of known natural GMOs was expanded by an order of magnitude, and facts were found in favor of the expression of agrobacterial genes in natural GMOs. The frequency of this phenomenon for dicotyledon plants has been estimated at 7 percent. Opine synthase genes turned out to be the predominant ones of agrobacterial origin in natural GMOs. They probably perform important functions in natural GMOs. In 2021, an article was published with an updated list of natural GMOs, but the list of genes expressed in natural GMOs has not been updated since 2019.The aim of this work is to update the list of opine synthase genes expressed in natural GMOs. The research methods included bioinformatic search using queries based on the sequences of opine synthase proteins from Agrobacterium rhizogenes, A. tumefaciens and A. vitis, their homologues from Ipomoea and Nicotiana plants, in the TSA database of the National Center for Biotechnology Information (NCBI) using the TBLASTN algorithm with default settings.The study resulted in the addition of another 18 species to the list of natural GMOs with expressed opine synthase genes, 12 of which belong to genera where natural GMOs were not previously described (Albizia, Cenostigma, Averrhoa, Gynostemma, Eurycoma, Gypsophila, Myosoton, Camptotheca, Gustavia, Eschweilera, Cestrum, Jasminum, and Paulownia).An analysis of the diversity of the detected sequences showed that homologues of cucumopine and mikimopine synthase predominate among them. The end products of these genes are optical isomers. In the future, it makes sense to start studying the functions of opine synthases in plants from these genes.

Ornamental plants are widespread and popular all over the world. Floriculture industry is of significant economic importance for some countries. Favorable prospects for the development of industrial floriculture were also noted for Russia. This can be facilitated by CRISPR/Cas, a breakthrough method of editing genes responsible for economically valuable traits of plants, which allows bypassing the limitations of the potential intraspecific variability of plants and solving the problem of obtaining non-transgenic modified plants. This article analyzes the current status of ornamental crop breeding using the CRISPR/Cas genetic editing method. The articles were selected from the Scopus database. A search encompassing 50 most common ornamental crops yielded the total of 26 articles on genetic editing using the CRISPR/Cas system, in particular: 8 articles featuring petunia; 1 per each crop on chrysanthemum, kalanchoe, poinsettia and tobacco; 2 per each on dendrobium, gentian, lily and torenia, and 3 per each on phalaenopsis and ipomoea. The found articles were divided into three groups. The first group includes works devoted to studies of mechanisms of genes controlling useful traits, as well as the optimization of the CRISPR/Cas method for a particular crop. The second group unites works aimed at modifying color of flowers and leaves. The third group includes works on increasing the life span of a flower and obtaining double flowers. The review offers the works on the optimization of gene editing in representatives of the orchid family Orchidaceae Juss. Also, it notes the prospects of gene editing by the CRISPR/Cas system, which can accelerate qualitative improvements in breeding and raise it effectiveness, it being especially important in present conditions.

Rakhmangulov","doi":"10.30901/2658-6266-2022-3-o1","DOIUrl":"https://doi.org/10.30901/2658-6266-2022-3-o1","url":null,"abstract":"Ornamental plants are widespread and popular all over the world. Floriculture industry is of significant economic importance for some countries. Favorable prospects for the development of industrial floriculture were also noted for Russia. This can be facilitated by CRISPR/Cas, a breakthrough method of editing genes responsible for economically valuable traits of plants, which allows bypassing the limitations of the potential intraspecific variability of plants and solving the problem of obtaining non-transgenic modified plants. This article analyzes the current status of ornamental crop breeding using the CRISPR/Cas genetic editing method. The articles were selected from the Scopus database. A search encompassing 50 most common ornamental crops yielded the total of 26 articles on genetic editing using the CRISPR/Cas system, in particular: 8 articles featuring petunia; 1 per each crop on chrysanthemum, kalanchoe, poinsettia and tobacco; 2 per each on dendrobium, gentian, lily and torenia, and 3 per each on phalaenopsis and ipomoea. The found articles were divided into three groups. The first group includes works devoted to studies of mechanisms of genes controlling useful traits, as well as the optimization of the CRISPR/Cas method for a particular crop. The second group unites works aimed at modifying color of flowers and leaves. The third group includes works on increasing the life span of a flower and obtaining double flowers. The review offers the works on the optimization of gene editing in representatives of the orchid family Orchidaceae Juss. Also, it notes the prospects of gene editing by the CRISPR/Cas system, which can accelerate qualitative improvements in breeding and raise it effectiveness, it being especially important in present conditions.","PeriodicalId":20582,"journal":{"name":"Plant breeding and biotechnology","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73504442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
