DELLA-mediated PIF degradation contributes to coordination of
网页2016年6月10日 · Reduction of PIF3 protein abundance by DELLAs correlates closely with reduced hypocotyl elongation. Both sequestration and degradation of PIF3 by DELLAs contribute to a reduction in PIF3...
Review Functions of Phytochrome-Interacting Factors (PIFs) in the ...
网页2023年7月31日 · PIF3 and EIN3 enhance HOOKLESS1 (HLS1) expression to suppress early chlorophyll biosynthesis and inhibit photobleaching. HLS1 suppresses HEMA while promoting PORA and PORB expression. Thus, PIF3 and EIN3 fine-tune the development of chlorophyll synthesis as shoot emerges from the soil [84].
Direct photoresponsive inhibition of a p53-like transcription ...
网页2021年9月23日 · Photoactivated phytochrome B (PHYB) binds to antagonistically acting PHYTOCHROME-INTERACTING transcription FACTORs (PIFs) to regulate hundreds of light responsive genes in Arabidopsis by...
Phosphorylation of PIF3 by MPK6 is required for coordinated …
网页2023年6月1日 · We analyzed the expressions of RL responsive miRNAs target and PIF3-regulated genes that play important roles in light mediated hypocotyl elongation and seedling development in Col-0, pif3 mutant and PIF3OE lines.
IAA3-mediated repression of PIF proteins coordinates light and
网页2021年2月18日 · This article reports a novel mechanism of light and auxin integration in Arabidopsis, mediated by the auxin transcriptional repressor IAA3 and light-controlled PIF transcription factors. IAA3 interacts with PIFs and inhibits their DNA binding activities, leading to hypocotyl elongation under different light conditions.
The epidermis coordinates thermoresponsive growth through the …
网页2020年2月26日 · In the dark, PIF4, together with three additional PIFs (PIF1, PIF3, and PIF5), promotes skotomorphogenesis including hypocotyl growth, a closed cotyledon, and hypocotyl negative gravitropism...
PIF3/HY5 module regulates - New Phytologist
网页2020年12月17日 · Transcriptional modules involving PIF3, HY5 and BBX11 regulate hypocotyl elongation. PIF3 inhibits BBX11 in the dark by directly binding to its promoter and inhibiting its transcription (Figs 4e–g, S4f). Upon transfer to light, HY5 binds to the G-box variant present in the promoter of BBX11 and induces its expression (Figs 5, 6).
Phytochrome-interacting factors (PIFs) regulate phytohormone …
网页2024年2月1日 · PIF3 is a bHLH transcription factor that interacts with phytochromes and regulates plant growth and development in response to light and stress. This review focuses on PIF3 identification, function, and interactions with phytohormones in various plant species and environmental conditions.
网页Here, we provide evidence from recently identified pif3 mutant alleles that PIF3 is necessary for early chloroplast greening and rapid phy-induced expression of nuclear genes encoding chloroplast components upon first exposure of seedlings to light.
Coordinated Regulation of Hypocotyl Cell Elongation by Light and ...
网页2018年1月8日 · Precise regulation of hypocotyl cell elongation is essential for plant growth and survival. Light suppresses hypocotyl elongation by degrading transcription factor phytochrome-interacting factor 3 (PIF3), whereas the phytohormone ethylene promotes hypocotyl elongation by activating PIF3.
