2,4-Dichlorophenoxyacetic acid (2,4-D) and other auxinic herbicides are important for weed control in cropping systems globally. Weeds with resistance to 2,4-D and other auxinic herbicides have evolved, including several populations of Sonchus oleraceus from multiple sites in Australia. We report the underlying mechanism in these populations that gives rise to auxinic herbicide resistance.

Soft rot (Pectobacterium aroidearum and Dickeya) is a devastating soil-borne bacterial disease that threatens konjac production. Intercropping with false acacia has been shown to significantly reduce soft rot incidence in konjac by shifting the microbial community. However, how intercropping shapes the root bacterial community and affects soft rot incidence remains unclear. To address this, we investigated three konjac intercropping systems (false acacia, paulownia, and maize) to explore the relationships among intercropping, soft rot incidence, root bacterial community, soil enzyme activity, and soil properties.
软腐病(Pectobacterium aroidearum 和 Dickeya)是一种毁灭性的土传细菌疾病,威胁着魔芋生产。通过改变微生物群落,与假刺槐间作可显著降低魔芋的软腐病发病率。然而,间作如何形成根部细菌群落并影响软腐病发病率仍不清楚。为了解决这个问题,我们研究了三种魔芋间作系统(假刺槐、泡桐和玉米),以探索间作、软腐病发病率、根部细菌群落、土壤酶活性和土壤特性之间的关系。

Rice leafroller is a serious threat to the production of rice. Monitoring the damage caused by rice leafroller is essential for effective pest management. Owing to limitations in collecting decent quality images and high-performing identification methods to recognize the damage, studies recommending fast and accurate identification of rice leafroller damage are rare. In this study, we employed an ultra-lightweight unmanned aerial vehicle (UAV) to eliminate the influence of the downwash flow field and obtain very high-resolution images of the damaged areas of the rice leafroller. We used deep learning technology and the segmentation model, Attention U-Net, to recognize the damaged area by the rice leafroller. Further, a method is presented to count the damaged patches from the segmented area.

BACKGROUNDMethyl jasmonate (MeJA) can affect the balance of hormones and regulate the disease resistance of plants. Exploring the application and mechanism of MeJA in inducing the tolerance of Pinus koraiensis to pine wood nematode (PWN) infection is of great significance for developing new strategies for pine wilt disease control.RESULTSDifferent concentrations (0.1, 1, 5 and 10 mm) of MeJA treatment groups showed differences in relative tolerance index and relative anti‐nematode index of P. koraiensis seedlings to PWN infection. The treatment of 5 mm MeJA solution induced the best tolerance effect, followed by the 1 mm MeJA solution. Transcriptome analysis indicated that many plant defense‐related genes upregulated after treatment with 1, 5 and 10 mm MeJA solutions. Among them, genes such as jasmonate ZIM domain‐containing protein, phenylalanine ammonia‐lyase and peroxidase also continuously upregulated after PWN infection. Metabolome analysis indicated that jasmonic acid (JA) was significantly increased at 7 days postinoculation with PWN, and after treatment with both 1 and 5 mm MeJA solutions. Integrated analysis of transcriptome and metabolome indicated that differences in JA accumulation might lead to ubiquitin‐mediated proteolysis, and expression changes in trans‐caffeic acid and trans‐cinnamic acid‐related genes, leading to the abundance differences of these two metabolisms and the formation of multiple lignin and glucosides.CONCLUSIONSMeJA treatment could activate the expression of defense‐related genes that correlated with JA, regulate the abundance of defense‐related secondary metabolites, and improve the tolerance of P. koraiensis seedlings to PWN infection. © 2024 Society of Chemical Industry.
背景茉莉酸甲酯(MeJA)可以影响植物体内激素的平衡,调节植物的抗病性。结果不同浓度(0.1、1、5 和 10 mm)的 MeJA 处理组对松材线虫感染的相对耐受指数和相对抗线虫指数均有差异。5 mm MeJA溶液的耐受效果最好,其次是1 mm MeJA溶液。转录组分析表明,用 1、5 和 10 mm MeJA 溶液处理后,许多植物防御相关基因上调。其中,含茉莉酸 ZIM 结构域蛋白、苯丙氨酸氨解酶和过氧化物酶等基因在感染 PWN 后也持续上调。代谢组分析表明,茉莉酸(JA)在接种 PWN 后 7 天以及用 1 毫米和 5 毫米 MeJA 溶液处理后显著增加。转录组和代谢组的综合分析表明,JA积累的差异可能会导致泛素介导的蛋白水解,以及反式咖啡酸和反式肉桂酸相关基因的表达变化,从而导致这两种代谢物的丰度差异,并形成多种木质素和葡萄糖苷。© 2024 化学工业协会。

BACKGROUNDThe whitefly Bemisia tabaci is one of the world's foremost agricultural pests. Recently, we found that a wild relative of tobacco (Nicotiana benthamiana) demonstrates remarkable attractiveness and nearly 100% lethality towards whiteflies. Therefore, it can act as a dead‐end trap crop for whitefly control in the field. However, the underlying mechanism of the significant attractiveness of N. benthamiana towards whiteflies is unclear.RESULTSBinary‐choice assays and olfactory experiments showed that compared to common tobacco (N. tabacum), the volatile of N. benthamiana has a greater attraction to whiteflies. Then we analyzed and compared volatiles from these two Nicotiana species by thermal desorption‐gas chromatography–mass spectrometry (TD‐GC–MS). We identified 16 chemical compounds that are more abundant in N. benthamiana than in N. tabacum. Seven compounds were further tested with olfactometer assays and we found that, among them, undecane strongly attracted whiteflies. Further experiments revealed that even 0.005 μg mL−1 undecane is attractive to whiteflies. We also silenced the genes that may influence the biosynthesis of undecane and found the production of undecane decreased after silencing NbCER3, and that N. benthamiana plants with less undecane lost their attraction to whiteflies. In addition, we found that applying 0.005 μg mL−1 undecane on yellow sticky traps can increase the number of stuck insects on the traps by ≈40%.CONCLUSIONUndecane from the volatile of N. benthamiana is a critical chemical signal that attracts whiteflies and NbCER3 involved in the biosynthesis of undecane. Undecane may be used to improve the efficiency of yellow sticky traps for whitefly control. © 2024 Society of Chemical Industry.
背景烟粉虱是世界上最主要的农业害虫之一。最近,我们发现烟草的一种野生近缘植物(Nicotiana benthamiana)对粉虱具有显著的吸引力和近 100%的致死率。因此,烟草可以作为田间防治粉虱的死角诱捕作物。结果二元选择测定和嗅觉实验表明,与普通烟草(N. tabacum)相比,本烟的挥发性物质对粉虱具有更大的吸引力。然后,我们通过热脱附-气相色谱-质谱法(TD-GC-MS)分析和比较了这两种烟草的挥发性物质。我们确定了 16 种化学物质,它们在 N. benthamiana 中的含量高于 N. tabacum。我们用嗅觉测定仪进一步检测了七种化合物,发现其中十一烷能强烈吸引粉虱。进一步的实验发现,即使是 0.005 μg mL-1 的十一烷也能吸引粉虱。我们还对可能影响十一烷生物合成的基因进行了沉默,发现沉默 NbCER3 后,十一烷的产量减少,而十一烷含量较低的 N. benthamiana 植株对粉虱的吸引力减弱。此外,我们还发现在黄色粘虫诱捕器上施用 0.005 μg mL-1 的十一烷可使粘在诱捕器上的昆虫数量增加≈40%。十一烷可用于提高黄色粘虫诱捕器防治粉虱的效率。© 2024 化学工业协会。

BACKGROUNDWheat is an important grain crop that has been under serious threat from Fusarium graminearum. Nup2, a member of the nuclear pore complex, plays an important role in regulating eukaryotic nuclear protein transport and participates in gene regulation. Dissecting the function of nuclear pore proteins in pathogenic fungi may provide effective targets for novel fungicides.RESULTSMutants exhibited nutritional growth defects, asexual/sexual developmental abnormalities. Deficiency of FgNup2 resulted in increased resistance of Fusarium graminearum to cell wall disruptors and increased sensitivity to metal ions. Pathogenicity analyses showed that the mutant was significantly less virulent on flowering wheat ears, consistent with the observed decrease in deoxynivalenol (DON) production.

背景小麦是一种重要的粮食作物,一直受到禾本科镰刀菌的严重威胁。Nup2 是核孔复合体的一个成员,在调节真核细胞核蛋白运输和参与基因调控方面发挥着重要作用。剖析核孔蛋白在病原真菌中的功能可为新型杀真菌剂提供有效靶标。结果突变体表现出营养生长缺陷、无性/有性发育异常。FgNup2 的缺失导致禾谷镰刀菌对细胞壁破坏剂的抗性增强,对金属离子的敏感性提高。致病性分析表明,该突变体对开花小麦穗的致病力明显降低,这与观察到的脱氧雪腐镰刀菌烯醇(DON)产生量减少一致。此外,我们还发现 FgNup2 与 TRI 家族的转录因子 FgTri6 有协同作用,可调控产毒基因的表达,进而影响 DON 及相关毒素的生物合成。© 2024 化学工业协会。

Nup2, a member of the nuclear pore complex, plays an important role in regulating eukaryotic nuclear protein transport and participates in gene regulation. Dissecting the function of nuclear pore proteins in pathogenic fungi may provide effective targets for novel fungicides.RESULTSMutants exhibited nutritional growth defects, asexual/sexual developmental abnormalities. Deficiency of FgNup2 resulted in increased resistance of Fusarium graminearum to cell wall disruptors and increased sensitivity to metal ions. Pathogenicity analyses showed that the mutant was significantly less virulent on flowering wheat ears, consistent with the observed decrease in deoxynivalenol (DON) production.
