4.6.1.12 down at 4°C, the enzyme expression is down-regulated at 0.05-0.1 mM indole 3-acetic acid. Methyl jasmonate and kinetin down-regulate the expression at 2 h and onwards 730357 4.6.1.12 additional information abscisic acid does not modulate enzyme expression 730357 4.6.1.12 up enzyme expression in seedlings treated with abscisic acid, H2O2 and drought is higher than in control seedlings 730270 4.6.1.12 up enzyme expression is higher in response to light as compared to plants kept under dark.The enzyme also exhibits a gradual up-regulation up to 6 h in response to gibberellic acid treatment 730357 4.6.1.12 up enzyme expression is up-regulated by exogenous elicitors including 0.1 mM methyl jasmonate, acetyl salicylic acid, absisic acid, and UV light 730628 4.6.1.12 up expression of genes encoding 1-deoxy-D-xylulose 5-phosphate synthase (DXS), 1-deoxy-D-xylulose 5-phosphate reductoisomerase (DXR) and 2-C-methyl-D-erytrithol 2,4-cyclodiphosphate synthase (MDS) is upregulated in plants inoculated with arbuscular mycorrhizal fungi. Presence of Zn and Mn is required from the expresssion of MDS, their enhanced uptake in inoculated plants could be responsible for the increased transcription of MDS. 749009 4.6.1.12 up higher expression levels in tender barks and leaves than that in roots and stems 709487
