Abstract GRAS transcription factors play important roles in plant abiotic stress response, but their characteristics and
functions in cotton have not been fully investigated. A cotton SCL4/7 subgroup gene in the GRAS family,
GhSCL4, was found to be induced by NaCl treatments. Nuclear localization and transactivation activity of GhSCL4
indicate its potential role in transcriptional regulation. Transgenic Arabidopsis thaliana over-expressing GhSCL4
showed enhanced resistance to salt and osmotic stress. What’s more, the transcript levels of salt stress-induced
genes (AtNHX1 and AtSOS1) and oxidation-related genes (AtAPX3 and AtCSD2) were more highly induced in
the GhSCL4 over-expression lines than in… More >
