We evaluated the molecular, anatomical and physiological properties of a soybean line transformed to improve drought tolerance with an rd29A:AtDREB1A construct.This construct expressed dehydrationresponsive element binding protein DREB1A from stress-inducible rd29A promoter.The greenhouse growth test included four randomized blocks plants, each treatment performed in triplicate.Seeds non-transformed cultivar BR16 genetically modified P58 (T 2 generation) were grown at 15% gravimetric humidity for 31 days.To induce water deficit, was reduced 5% (moderate stress) 29 days ©FUNPEC-RP www.funpecrp.com.
