Roles of strigolactones in rice responses to salinity and arsenic toxicity

1.用电感耦合等离子体质谱(ICP-MS)对缺砷突变体D10和D17的根部和地上部的砷(As)含量进行了测定，结果表明，缺SL突变体的As积累较多，尤其是在根部。2.与氧化胁迫、膜完整性、光合作用、在AS暴露的WT和SL缺失突变体中的非酶和酶类抗氧化剂表明，SL突变植株在生化水平上比WT3.参与抗氧化系统和谷胱甘肽代谢的几个基因在生化水平上受到更大的损害。qRT-PCR结果表明，与突变体相比，随着胁迫的发生，WT植株中大多数研究基因的转录显著上调。4.WT和SL缺失突变体的代谢组学、脂谱和激素水平的数据表明，许多代谢产物，包括参与重要生化途径的脂类，以及激素水平，与d10和d17.5相比，盐胁迫下KAI2突变体在盐适应过程中的表达显著上调。其他生理、生化和分子数据目前正在分析中。6.同时，我们已经发表了3篇文章，其中包括2篇2018财年的综述文章，列在下面的部分。

1.The results on arsenic (As) in the roots and shoots of As-treated WT and strigolactone (SL)-deficient mutants d10 and d17 using ICP-MS suggest that SL-deficient mutants accumulate more As, especially in the roots compared with WT.2.Various biochemical parameters linked to oxidative stress, membrane integrity, photosynthesis, non-enzymatic and enzymatic antioxidants in As-exposed WT and SL -deficient mutants implied that SL-mutant plants were more compromised at biochemical levels to fight against As-toxicity in comparison with WT.3.qRT PCR results of several genes involved in antioxidant system and glutathione metabolism suggest that As stress significantly upregulated the transcripts of most of the studied genes in WT plants when compared mutant plants.4.The obtained data on metabolomics, lipid profiling and hormone levels in WT and SL -deficient mutants suggest that many metabolites, including lipids involved in important biochemical pathways, as well as hormonal levels, particularly in roots were significantly upregulated in WT under As stress when compared with those in d10 and d17.5.The data on the roles of karrikins in salt adaptation clearly indicate that Kai2 mutants grown under salt stress exhibited severe growth defects when compared with WT. The other physiological, biochemical and molecular data are currently under analysis.6.Meanwhile, we have published 3 articles, including 2 review articles in the FY 2018 that are listed in the below section.
