PIF3 Antibody

1. PIF degradation by DELLAs is required to coordinate light and gibberellins signals. PMID: 27282989
2. study uncovers an important role of PIF3 in Arabidopsis freezing tolerance by negatively regulating the expression of genes in the CBF pathway PMID: 28739888
3. PIF3 and TOC1 display coincident cobinding to dawn-phased genes under diurnal short-day conditions. They interact and colocalize in the nucleus. TOC1 acts directly as a transcriptional repressor of PIF3, which itself acts intrinsically as a transcriptional activator so that PIF3 and TOC1 act antagonistically in regulating the expression of their cotarget genes. PMID: 27071129
4. Under negative day-night temperature difference, lower auxin biosynthesis activity limits the signaling in this pathway, resulting in low activity of PIF3 and short hypocotyls. PMID: 25516603
5. PIF3 phosphorylation induces, and is necessary for, recruitment of LRB [Light-Response Bric-a-Brack/Tramtrack/Broad (BTB)] E3 ubiquitin ligases to the PIF3-phyB complex. PMID: 24904166
6. Data indicate that HDA15 and PIF3 cotarget to the genes involved in chlorophyll biosynthesis and photosynthesis in the dark and repress gene expression. PMID: 23548744
7. These results showed an altered response to light in seedlings with an impaired PIF3/MIDA regulatory network. PMID: 22499182
8. directly activated by ETHYLENE-INSENSITIVE 3 and indispensible for ethylene-induced hypocotyl elongation in light PMID: 22818915
9. The PIF3 protein abundance oscillates under diurnal conditions as a result of a progressive decline in PIF3 protein degradation mediated by photoactivated phyB, and consequent accumulation of the bHLH factor during the dark period. PMID: 22409654
10. PIF3 regulates genes misexpressed in the dark, named MIDA genes PMID: 22108407
11. PIF3 acts transiently, and its major function is to mediate phytochrome-induced signaling during the developmental switch from skotomorphogenesis to photomorphogenesis and/or dark to light transitions PMID: 15155879
12. PIF3 may function in early phytochrome signaling at the dark-to-light transition, not only during initial seedling deetiolation, but daily at dawn under diurnal light-dark cycles. PMID: 15505214
13. Data suggest that PIF3 may represent the primary intermolecular signaling transaction of the activated photoreceptor, tagging the target protein for proteosomal degradation. PMID: 16885032
14. Data provide evidence that the mechanism by which PIFs3operate on the phyB signaling pathway under prolonged red light is through maintaining low phyB protein levels, in an additive or synergistic manner. PMID: 18252845
15. Data show that dephosphorylation of PIF3 is mediated by phytochrome-associated protein phosphatase type 2C. PMID: 18564962
16. PIF3 was circadian regulated in dark-grown seedlings. PMID: 19380736
