The G-protein α subunit GhGPA positively regulates Gossypium hirsutum resistance to Verticillium dahliae via induction of SA and ja signaling pathways and ROS accumulation

The Crop Journal 2021年第4期9卷 823-833页

Verticillium wilt, a devastating disease in cotton caused by Verticillium dahliae, reduces cotton quality and yield. Heterotrimeric GTP-binding proteins, consisting of Ga, Gb, and Gc subunits, transducers of receptor signaling, function in a wide range of biological events. However, the function of Ga proteins in the regulation of defense responses in plants is largely unexplored, except for a few reports on model species. In the present study, a cotton G-protein a-subunit-encoding gene(GhGPA) was isolated from Verticillium wilt-resistant Gossypium hirsutum(upland cotton) cv. ND601. GhGPA transcription was up-regulated under V. dahliae stress, with higher expression in tolerant than in susceptible cotton *** localization revealed GhGPA to be located in the plasma membrane. GhGPA shows high(85.0%) identity with Arabidopsis AT2 G26300(AtGPA1), and AtGPA1 gpa1-4 mutants displayed susceptibility to V. dahliae. Ectopic expression of GhGPA successfully restored the resistance of Arabidopsis gpa1-4 mutants to Verticillium wilt and made them more resistant than the wild type. Overexpression of GhGPA in Arabidopsis markedly increased the resistance and resulted in dramatic up-regulation of pathogenesis-related(PR) genes and increased in H2 O2 accumulation and salicylic acid(SA) and jasmonic acid(ja) contents. However, suppressing GhGPA expression via virus-induced gene silencing(VIGS)increased susceptibility to Verticillium wilt, down-regulated the expression of PR and marker genes in SA and ja signaling pathways, and reduced H2 O2 content. The contents of SA and ja in Arabidopsis gpa1-4 and VIGS cotton were lower than those in the wild type and empty-vector control. However,GhGPA-overexpressing Arabidopsis contained more SA and ja than the wild type when inoculated with V. dahliae. Thus, GhGPA plays a vital role in Verticillium wilt resistance by inducing SA and ja signaling pathways and regulating the production of reactive oxygen species. These findings

为了找到某道轨轮失效的根本原因,对道轨轮的断口进行了理化检测及形貌分析。结果表明:道轨轮抗拉强度576 MPa、屈服强度351 MPa,延伸率9.5%,硬度208 HBW,金相组织为铁素体+珠光体、珠光体占35%,球化率4级,均符合技术要求。断口裂纹源起源于R圆角的过渡部位,电镜扫描分析表明裂纹源处无夹杂物,开裂主要是由于过渡圆角较小、表面凸凹不平以及安全系数过低造成的。针对开裂原因采取改进措施,改进后的道轨轮服役超过2 a未出现开裂,彻底解决了问题。

Journal of Forestry Research 2015年第1期26卷 71-77页

作者： Xiaodong dai Yaguang Zhan Jiechi Zhang Piqi Zhang Zenghua Han Qingfang ma Xianghui Kong Jianing Liu Yinpeng ma College of Life Science Northeast Forestry University Microbiology Institute of Heilongjiang Provincial Academy of Sciences Institute of High Technology Heilongjiang Academy of Science

We evaluated the biomass and ergosterol content of Hericium erinaceus mycelium, and extracellular enzyme activities in H. erinaceus liquid culture following salicylic acid（SA） and methyl jasmonic acid（Me ja）supplementation. The optimal SA concentration was100 lmoláL-1, where the highest ergosterol content of 2.33 mgág-1was obtained following 6-day cultivation with100 lmoláL-1SA supplementation, and which was significantly higher than the unsupplemented control（p ／ 0.01）. Following 4-day supplementation with50 lmoláL-1Me ja, the highest ergosterol content obtained was 1.988 mgág-1, which was 25.8 % higher than the unsupplemented control. Our data indicate that SA and Me ja supplementation improves ergosterol content in *** mycelium.
