The phyA-mediated high-irradiance response and GI play pivotal roles in morning FT induction.
Quoted textsource-backed
Therefore, the phyA-mediated high-irradiance response and GI play pivotal roles in morning FT induction.
phyA influences cry2 stability because a phyA mutant has enhanced cry2 levels, particularly under low fluence rate blue light.
Quoted textsource-backed
a phyA mutant had enhanced cry2 levels, particularly under low fluence rate blue light
cry2 stability is controlled by SPA and phyA.
Quoted textsource-backed
Our results suggest that cry2 stability is controlled by SPA and phyA
Light induces peroxisome proliferation in Arabidopsis seedlings.
Quoted textsource-backed
We provide evidence that light induces proliferation of peroxisomes in Arabidopsis seedlings
phyA and hyh mutants exhibit reduced peroxisome abundance.
Quoted textsource-backed
the phyA and hyh mutants exhibit reduced peroxisome abundance
HYH and PEX11b constitute a branch of the phyA-mediated light signaling cascade that promotes peroxisome proliferation during seedling photomorphogenesis.
Quoted textsource-backed
We conclude that HYH and PEX11b constitute a novel branch of the phyA-mediated light signaling cascade, which promotes peroxisome proliferation during seedling photomorphogenesis.
phytochrome A and HYH are required for the up-regulation of PEX11b in the light.
Quoted textsource-backed
The far-red light receptor phytochrome A (phyA) and the bZIP transcription factor HY5 HOMOLOG (HYH) are both required for the up-regulation of PEX11b in the light.
Overexpression of PEX11b rescues the reduced peroxisome abundance phenotype in phyA and hyh mutants.
Quoted textsource-backed
a phenotype that can be rescued by overexpressing PEX11b in these plants
Rapid light-induced degradation of PIF3 indicates that interaction of PIF3 with phytochrome species is transient.
Quoted textsource-backed
Rapid light-induced degradation of PIF3 indicates that interaction of PIF3 with these phytochrome species is transient.
Light-induced PIF3 degradation is controlled by the concerted action of phyA, phyB, and phyD photoreceptors.
Quoted textsource-backed
This process is controlled by the concerted action of the R/FR absorbing phyA, phyB, and phyD photoreceptors
phyA mediates far-red light promotion of flowering with modes of action similar to cry2.
Quoted textsource-backed
we show that phyA mediates far-red light promotion of flowering with modes of action similar to that of cry2.
Individual phytochromes and cryptochromes work together to confer photoperiodic responsiveness in Arabidopsis, and this responsiveness depends on light quality.
Quoted textsource-backed
Based on these results and a finding that the photoperiodic responsiveness of plants depends on light quality, a model is proposed to explain how individual phytochromes and cryptochromes work together to confer photoperiodic responsiveness in Arabidopsis.
cry2 and phyA protein abundance show a diurnal rhythm in plants grown in short-day but not in plants grown in long-day.
Quoted textsource-backed
The protein abundance of cry2 and phyA showed a diurnal rhythm in plants grown in short-day but not in plants grown in long-day.
cryptochrome 2 and phytochrome A act as day-length sensors in Arabidopsis.
