Comparative functional analyses of DWARF14 and KARRIKIN INSENSITIVE 2 in drought adaptation ofArabidopsis thaliana

SUMMARY Functional analyses of various strigolactone‐deficient mutants have demonstrated that strigolactones enhance drought resistance; however, the mechanistic involvement of the strigolactone receptor DWARF14 (D14) in this trait remains elusive. In this study, loss‐of‐function analysis of the D14 gene in Arabidopsis thaliana revealed that d14 mutant plants were more drought‐susceptible than wild‐type plants, which was associated with their...
