4. PHYA, but not PHYB, is essential for fine-tuning the chlorophyll biosynthetic pathway in response to partial shading. PMID: 24604733
5. nuclear FHY1 can either act independently of phyA or act in association with phyA to activate the expression of distinct target genes PMID: 25071219
6. phytochrome A function in Arabidopsis seed germination PMID: 23292879
7. Distinct structural modules, each of which confers different properties to phyA, are assembled on the phyA molecule. PMID: 22843485
8. We present here a hypothesis to explain how the identified amino acid substitution may lead to structural changes manifested as altered signaling and phenotype displayed by the phyA-5 mutant (which shows reduced binding affinity to FHY1/FHL). PMID: 22516823
9. phyA controlles cry2 stability PMID: 22739826
10. The truncated PHYA406 proteins inactivate COP1 in the nuclei in a light-independent fashion. PMID: 22498774
11. Nuclear phyA accelerates phototropism. In the fhy1 fhl mutant, in which phyA remains in the cytosol, phototropic bending is slower than in the wild type. PMID: 22374392
12. PHYA amino-terminal extension domain plays a role in regulating the nuclear import of PHYA. PMID: 21969386
13. hypomethylation at a specific CG site in exon 1 was consistently associated with the release of phyA' epiallele silencing. PMID: 22466452
14. A role for mesophyll-specific phyA in blue-light-dependent regulation of anthocyanin levels and novel roles for individual phy isoforms in the regulation of anthocyanin accumulation under red illumination, is reported. PMID: 21455024
15. Study unravels the mechanism underlying this shift of the phyA action peak from red to far-red light and show that it relies on specific molecular interactions rather than on intrinsic changes to phyA's spectral properties. PMID: 21884939
16. The dracula 1 (dra1) mutant, that showed no avoidance of shade for the PHYB::LUC response, was the result of a mutation in the PHYA gene. PMID: 21398429
17. Reversible activation and repression of phyA expression by darkness and light, respectively, is accompanied by reversible changes in H3 and H4 modifications of the phyA locus. PMID: 21317377
18. The phyA N-terminal fragment is imported into the nucleus in a light-dependent fashion. Deletion of the C-terminal domain of phyA compromises light-induced degradation of phyA in a compartmentalization-independent fashion. PMID: 21169346
19. phyA without a nuclear localization or export signal sequence is localized exclusively in the cytoplasm in darkness. Rapid nuclear entry was observed after exposure to both red and far-red light. PMID: 20739301
20. phyA regulates wound- and jasmonic acid-mediated JAZ1 degradation. PMID: 20435902
21. Data show that phyA degradation is significantly slower in the cytoplasm than in the nucleus. PMID: 20473552
22. Results suggest that the autophosphorylation of phyA plays an important role in the regulation of plant phytochrome signaling through the control of phyA protein stability. PMID: 20203237
23. Genetic variations in the PhyA locus of A. thaliana inbred strains and the effects on seedling growth under infrared light are reported. PMID: 15908601
24. The potential of manipulating light signal-transduction pathways to minimize the problems of lodging in basmati/aromatic rice and to enhance grain productivity is reported. PMID: 16136335
25. data indicate that phyA, the 26S proteasome, and the Constitutive Photomorphogenic/De-Etiolated/Fusca proteins are all involved in the light regulation of FHY1 protein abundance during Arabidopsis (Arabidopsis thaliana) seedling development PMID: 16244150
26. PHYC was the most strongly associated locus across 163 strains, suggesting that PHYC alleles are under diversifying selection in A. thaliana PMID: 16732287
27. This study showed that phyA has a quantitatively dominant role in Rc-induced expression of early response genes in A. thaliana seedlings. PMID: 17076805
28. The serine-rich region is involved in negative regulation of phyA signaling. PMID: 17160561
29. Results raise the possibility that phyA may contribute significantly to the regulation of growth and development in daylight-grown plants. PMID: 17346261
30. Data showed a transcriptionally suppressed epi-allele of phytochrome A gene (PHYA) methylated only in symmetric CG sites resident in exonic regions, resulting in elongated hypocotyls in seedlings grown under continuous far-red light. PMID: 17931351
31. required for the up-regulation of PEX11b in the light PMID: 18203870
32. The expression levels of polyamine biosynthesis-related genes were wtranscribed less in the wild type than in phyA seedlings under both light conditions. PMID: 18375607
