Light induces peroxisome proliferation in Arabidopsis seedlings.
Quoted textsource-backed
We provide evidence that light induces proliferation of peroxisomes in Arabidopsis seedlings
PEX11b is a direct target of HYH.
Quoted textsource-backed
suggesting that the PEX11b gene is a direct target of HYH
HYH binds to the promoter of PEX11b.
Quoted textsource-backed
The HYH protein is able to bind to the promoter of PEX11b
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
