2022年8月29日 · We found that shade combined with warm temperature produces a synergistic hypocotyl growth response that dependent on PHYTOCHROME-INTERACTING FACTOR 7 (PIF7) and auxin. This unique but...

2024年9月13日 · PIF7 is considered a master regulator of SAS, as evidenced by the strong shade-defective response of pif7 mutant plants 7, 8. PIF7 is less vulnerable than PIF1/3/4/5 to the rapid turnover...

2019年12月2日 · In this study, we found that CONSTANS (CO) and PHYTOCHROME-INTERACTING FACTOR 7 (PIF7) have an additive effect on shade-induced flowering, but that LONG HYPOCOTYL IN FAR-RED1 (HFR1) represses early flowering by binding to CO and PIF7 and preventing the binding of CO to the promoter of FLOWERING LOCUS T (FT) and the binding of PIF7 to the ...

2023年4月17日 · Phytochrome-interacting factor 7 (PIF7) is a major transcriptional regulator of SAS in Arabidopsis; however, how it regulates gene expression is not fully understood. Here, we show that PIF7 directly interacts with the histone chaperone anti-silencing factor 1 (ASF1).

2020年4月13日 · Enhanced PIF7 protein levels directly activate the thermomorphogenesis pathway by inducing the transcription of key genes such as the auxin biosynthetic gene YUCCA8, and are necessary for...

We show that a previously uncharacterized Arabidopsis thaliana basic helix-loop-helix (bHLH) phytochrome interacting factor (PIF), designated PIF7, interacts specifically with the far-red light-absorbing Pfr form of phyB through a conserved domain called the active phyB binding motif.

2019年12月2日 · This study reveals that PIF7, a key transcription factor involved in SAS in Arabidopsis, together with CONSTANS, balanced by HFR1, controls flowering-related gene expression and promotes shade-induced earlier flowering.

已有研究表明，低r/fr条件诱导拟南芥下胚轴伸长生长，主要通过转录因子pif7（phytochrome interacting factor 7）诱导生长素合成及其信号转导基因或者细胞伸长相关基因表达，如yuc8、yuc9、iaa19、iaa29和xtr7等。hfr1能与pif结合，抑制pif功能。

2023年12月26日 · Phytochrome-interacting factor 7 (PIF7) is an essential regulator that integrates shade signals into plant transcriptional networks. While the regulation of PIF7 under shade conditions has been well studied, the mechanism that represses PIF7 activity under white light remains ambiguous.

Phytochrome-interacting factor 7 (PIF7) is an essential regulator that in-tegrates shade signals into plant transcriptional networks. While the regulation of PIF7 under shade condi-tions has been well studied, the mechanism that represses PIF7 activity under white light remains ambig-uous.
