Transcriptional repression of GTL1 by water-deficit stress promotes anthocyanin and polyamine biosynthesis to enhance drought tolerance

ABSTRACT: GT2-LIKE 1 (GTL1) is a negative regulator of stomatal development and its repressed expression under water deficit can result in enhanced drought tolerance. As a transcription factor, GTL1 has been implicated in diverse developmental roles. We hypothesized that GTL1 represses multiple drought tolerance pathways, leading to the drought tolerance phenotype of the gtl1-4 knockout mutant. RNA-Seq data indicates that GTL1 regulates genes involved in ribosome biogenesis in emerging leaves and secondary metabolite synthesis in expanding leaves.
