Roles of strigolactones in rice responses to salinity and arsenic toxicity

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.
