Abstract

The development of drought tolerant plants is a high priority because the area suffering from drought is expected to increase in the future due to global warming One strategy for the development of drought tolerance is to genetically engineer plants with transcription factors TFs that regulate the expression of several genes related to abiotic stress defense responses This work assessed the performance of soybean plants overexpressing the TF DREB1A under drought conditions in the field and in the greenhouse Drought was simulated in the greenhouse by progressively drying the soil of pot cultures of the P58 and P1142 lines In the field the performance of the P58 line and of 09D0077 a cross between the cultivars BR16 and P58 was evaluated under four different water regimes irrigation natural drought no irrigation and water stress created using rainout shelters in the vegetative or reproductive stages Although the dehydrationresponsive elementbinding protein DREB plants did not outperform the cultivar BR16 in terms of yield some yield components were increased when drought was introduced during the vegetative stage such as the number of seeds the number of pods with seeds and the total number of pods The greenhouse data suggest that the higher survival rates of DREB plants are because of lower water use due to lower transpiration rates under well watered conditions Further studies are needed to better characterize the soil and atmospheric conditions under which these plants may outperform the nontransformed parental plantsThis work was supported by the Science and Technology Research Partnership for Sustainable Development SATREPS of the Japan Science and Technology Agency/Japan International Cooperation Agency JIRCAS Empresa Brasileira de Pesquisa Agropecuária Coordenação de Aperfeiçoamento de Pessoal de Nível Superior CAPES Londrina State University UEL/Brazil
