A bHLH Transcription Factor Confers Salinity Stress Tolerance in Betula platyphylla.

ABSTRACT: Basic helix-loop-helix (bHLH) proteins comprise a large family of transcription factors that are involved in plant growth and development, as well as responses to various types of environmental stress. Betula platyphylla (birch) is a pioneer tree species in secondary forest that plays a key role in maintaining ecosystem stability and forest regeneration, but few bHLHs involved in abiotic stress responses have been unveiled in birch. In this study, nine BpbHLH TFs related to stress responses in the birch genome were identified. Quantitative real-time polymerase chain reaction (RT-PCR) analysis indicated that the expression of these TFs can be induced by salt stress, and the expression of BpbHLH1 was higher than that of other BpbHLH genes.
