Abstract
HY5 (ELONGATED HYPOCOTYL5), a bZIP transcription factor, is one of the main regulators of light and hormonal signaling. Among the targets of this gene, the genes for the transcriptional complex of chloroplasts whose coordinated expression ensures the initial stages of photomorphogenesis are particularly significant. In this study, we showed that, during de-etiolation, HY5 functions as a positive CK-dependent regulator of the expression of genes encoding proteins associated with plastid RNA polymerase (PAP), which functions below the primary chain of sensing the cytokinin signal. The absence of blocking effect of mutations of the CRY1, CRY2, PHYA, and PHYB photoreceptor genes on the CK-dependent content of PAP gene transcripts indicates the parallel action of the hormone and light in their regulation.中文翻译:
