EXPRESSION
ORGANISM
UNIPROT
LITERATURE
higher TaPSY expression is observed at 7 and 21 days after anthesis than 14 days after anthesis
-
mRNA level increases when dark-grown seedlings come from dark to light, which leads to a deetiolation and the forming of chloroplasts, similar results can be observed with seedlings growing in the dark when treated with paclobutrazol, an inhibitor of the regulatory hormone gibberellin
-
specific upregulation of a cotton phytoene synthase gene produces golden cottonseeds with enhanced provitamin A
-
the expression of gene crtB in cells cultured at 25°C under continuous illumination increases 1.3fold relative to control
the phytochrome-interacting factor (PIF) family represses PSY expression in etiolated seedlings and mature leaves, but does not influence PSY expression in roots
the presence of light responsive elements in TaPSY promoters might be responsible for their higher expression in green tissues as compared to the root
-
the PSY gene is induced by light in photosynthetic tissues, while a root-specific upregulation of PSY expression is iduced by salt stress and abscisic acid. Light-sensitive phytochrome-interacting factors are not required to regulate phytoene synthase gene expression in the root
the TaPSY3 was highly upregulated during the drought stress
