Abstract:

Drought and high temperature are major environmental factors that severely limit plant productivity worldwide. Agricultural production faces serious threats from frequent extreme weather conditions. Maize (Zea mays L.) is a major crop greatly affected by drought and high temperature in the China and worldwide. Previously, expression of ABP9 in transgenic Arabidopsis leads to enhanced tolerance to temperature and oxidative stresses. It is proved that the expression of ABP9 gene maize on the basis of different superior phenotypes for drought tolerance is essential and prerequisite for grain development. In this research, we evaluated ten events of [Pubi-ABP9 (06 construct)] of transgenic maize for drought tolerance at vegetative & reproductive stages under field conditions and identified several phenotypes showed high tolerance to drought. Tolerant construct of [Pubi-ABP9.1 (06 construct)] (611, 616 & 617) at vegetative stage and drought applied during reproductive stage (617& 618) events were able to maintain comparatively adequate phenotypes chlorophyll fluorescence, NDVI, reduced ASI & enough grain yield was recorded compared to the non-transgenic controls and the use of such resources to produce transgenic maize are able to alleviate the negative impacts of drought stresses on the growth, development and grain yield of maize.
