| 1 | Cotton GhBAK1 Mediates Verticillium Wilt Resistance and Cell Death显示文摘导致病毒的基因 silencing (VIGS ) 由将他们的表示击倒为单个基因的功能的分析提供一条强大的途径。我们采用了这条途径把在对 Verticillium 抵抗的棉花的基因功能枯萎,世界范围的大多数破坏疾病之一。我们这里证明高度有效的 VIGS 在与部分抵抗引起线(CA4002 ) 到 Verticillium 的一朵棉花被获得枯萎,并且 GhMKK2 和 GhVe1 为它的抵抗被要求到 Verticillium 枯萎。Arabidopsis AtBAK1/SERK3,在工厂疾病抵抗的一个中央管理者,与五个成员,一起属于体的 embryogenesis 受体 kinases (SERK ) 的一个亚科 AtSERK1 到 AtSERK5。二 BAK1 orthologs 和一 SERK1 ortholog 在棉花染色体被识别。重要地, GhBAK1 为 CA4002 抵抗被要求到 Verticillium 枯萎。令人惊讶地, GhBAK1 的 silencing 是足够的触发在棉花伴有反应的氧种类的生产的房间死亡。这结果从 AtBAK1 和 AtSERK4 在房间死亡控制在玩冗余的函数的 Arabidopsis 是不同的。显然,而 AtSERK4/5 是在 Arabidopsis 的最新发展的基因,棉花仅仅发展了 SERK1 和 BAK1。我们的研究在 Verticillium 显示 BAK1 的功能的重要性枯萎抵抗并且在不同植物种类建议 SERK 家庭成员的动态进化。 | Xiquan Gao Fangjun Li Maoying Li Ali S.Kianinejad Jane K.Dever Terry A.Wheeler Zhaohu Li Ping He Libo Shan | 2013 | Journal of Integrative Plant Biology2013，55，7： | 13 |
| 2 | Editing of an effector gene promoter sequence impacts plant-Phytophthora interaction显示文摘Pathogen avirulence(Avr) effectors interplay with corresponding plant resistance(R) proteins and activate robust plant immune responses. Although the expression pattern of Avr genes has been tied to their functions for a long time, it is still not clear how Avr gene expression patterns impact plant-microbe interactions. Here, we selected Ps Avr3b, which shows a typical effector gene expression pattern from a soybean root pathogen Phytophthora sojae. To modulate gene expression, we engineered Ps Avr3b promoter sequences by in situ substitution with promoter sequences from Actin(constitutive expression), Ps XEG1(early expression), and Ps NLP1(later expression) using the CRISPR/Cas9. Ps Avr3b driven by different promoters resulted in distinct expression levels across all R the tested infection time points. Importantly, those mutants with low Ps Avr3b expression successfully colonized soybean plants carrying the cognate R gene Rps3b. To dissect the difference in plant responses to the Ps Avr3b expression level, we conducted RNA-sequencing of different infection samples at 24 h postinfection and found soybean immune genes,including a few previously unknown genes that are associated with resistance. Our study highlights that fine-tuning in Avr gene expression impacts the compatibility of plant disease and provides clues to improve crop resistance in disease control management. | Sylvans Ochola Jie Huang Haider Ali Haidong Shu Danyu Shen Min Qiu Liyuan Wang Xi Li Han Chen Alex Kange Dinah Qutob Suomeng Dong | 2020 | Journal of Integrative Plant Biology2020，62，3： | 1 |
