PtrbZIP3 transcription factor regulates drought tolerance of Populus trichocarpa

Plant basic leucine zipper(bZIP)proteins participate in plant development and a variety of abiotic stress responses.However,their roles in response to abiotic stress in Populus are still unclear.In this study,we characterized a bZIP protein,PtrbZIP3,in Populus trichocarpa which belongs to the sub-family A.PtrbZIP3 expression was highly induced by treatment with NaCl,PEG6000,or abscisic acid(ABA).PtrbZIP3 is a nuclear protein with transcriptional activation a…查看全部>>
