Horizonte para a competitividade: anais. Porto Alegre: IRGAc2015  aDrought stress, which can negatively affect plant growth and productivity, has become an increasingly severe problem worldwide. It is, therefore, a major constraint on rice production in waterlimited environments. The development of rice varieties with increased tolerance to drought, by both conventional and molecular breeding methods and by genetic engineering, is an important strategy to meet global rice demands with less water. In this study, we developed transgenic rice lines harboring the gene CAHB12 from Coffeearabica. Agrobacterium tumefaciens strain EH105 carrying the pUCE plasmid was used.  aArroz  aEngenharia genética  aOryza sativa  aPlanta transgênica1 aGUIMARÃES, L. S. M.1 aCOELHO, G. R. C.1 aLAU, E.
