Ectopic expression of MYB repressor GmMYB3a improves drought tolerance and productivity of transgenic peanuts (Arachis hypogaea L.) under conditions of water deficit
Peanut is widely grown and provides protein and edible oil for millions of people. Peanut growth and productivity are frequently negatively affected by abiotic and biotic environmental factors. However, the research on improving peanut germplasm resources by genetic transformation is very limited. H...

| description | Peanut is widely grown and provides protein and edible oil for millions of people. Peanut growth and productivity are frequently negatively affected by abiotic and biotic environmental factors. However, the research on improving peanut germplasm resources by genetic transformation is very limited. Here, the novel R2R3-MYB repressor
GmMYB3a
was introduced into peanut plants by
Agrobacterium
-mediated transformation for the first time for thorough evaluation of the function of
GmMYB3a
in drought stress plant responses. We generated
GmMYB3a
-transgenic peanut plants. The
GmMYB3a
-overexpressing lines showed significantly improved physiological responses and no yield loss non-transgenic plants, in terms of survival rates. Thus, the
GmMYB3a
-overexpressing plants showed better photosynthetic performance, higher relative water content, and greater water use efficiency, demonstrating their adaptive capacity to water deficit. We conclude that overexpression of
GmMYB3a
can improve drought tolerance and productivity in peanut. |
