Title : Tartary buckwheat serine/threonine-protein kinase FtAUR3 enhance plant salt resistance

Abstract:

Tartary buckwheat is an environmentally friendly crop but sensitive to salt stress, and salt stress result in water loss, stomatal closure, affect photosynthesis and metabolism, and reduce yield and quality of buckwheat. Thus, it is crucial to understand the mechanism of buckwheat salt tolerance. In this research, we identified a serine/threonine-protein kinase Aurora-3 family (FtAUR3) gene that is significantly associated with salt tolerance of Tartary buckwheat by genome-wide association analysis (GWAS). And transcriptome analysis shows that the FtAUR3 was up-regulated in response to salt stress. So we carry out the overexpression of FtAUR3 in buckwheat hairy roots and Arabidopsis thaliana, and we found that transgenic plant can enhanced salt tolerance compared to wild type plants. Taken together, these results demonstrated that FtAUR3 may be critical to regulate Tartary buckwheat resistance mechanism to against salt stress. Our results can provide reference for the study of plant resistance to salt stress.

What will audience learn from your presentation?

• This research can help people know more about the plant salt tolerance.
• This research can give a new perspective about serine/threonine-protein kinase regulated plant development.
• This research can help breeders to breed salt resistant varieties.
