Posttranslational Modification

EC Number Posttranslational Modification Comment Organism

Source Tissue

EC Number Source Tissue Comment Organism Textmining
2.5.1.32 leaf abiotic stress leads to increases in isoform PSY2 transcript levels Zea mays
-
2.5.1.32 additional information isoform PSY1 mRNA is not increased by abiotic stress in any tissue examined Zea mays
-
2.5.1.32 root drought-stressed root shows elevated levels of isoform PSY3 transcripts and abscisic acid, the effect is reversed by hydratation. Increase in isoform PSY3 mRNA correlates with carotenoid accumulation and with increase in 9-cis-epoxycarotenoid dioxygenase transcripts, and blocking of carotenoid biosynthesis interferes with stress-induced accumulation of abscisic acid Zea mays
