Abstract WRKY transcription factors play important roles in plant growth, development, and stress responses. Our previous research has shown that the GhWRKY91 gene can delay age-, abscisic acid (ABA)-, and drought-induced
leaf senescence when overexpressed in transgenic Arabidopsis plants. To explore in more depth the biological
functions of the GhWRKY91 gene, we further observed the root growth of overexpressing transgenic Arabidopsis thaliana under ABA and drought treatment. In this study, we transplanted the germinated seeds of wild-type
(WT) and three transgenic lines (OE-12, OE-13 and OE-20) to 1/2 MS solid medium containing ABA and different concentrations of mannitol (simulated drought treatment)… More >
