摘要

Use of cahbi2 coffee homeobox gene in the production of transgenic plants more tolerant to water deficit and salt stress. The proposed innovation is related to the plant bioteonological improvement of species of commercial interest. More specifically, the present invention relates to the production of transgenic plants more tolerant to water deficit and salt stress by the expression of a new coffee gene (sp. Coffea arabica), belonging to the hd-zip family, characterized by the presence of homedomain associated with a leucine zipper. The expression of this transcriptional factor is induced in leaves and roots of coffee plants subjected to different water deficit conditions (moderate and severe), and transgenic plants overexpressing this gene have a higher tolerance, both at different drought levels, as well as at low levels. high salt concentrations.
