physiological function
CCoAOMT gene may play a role in innate generalized response to pathogen infection. CCoAOMT gene plays an essential role in the synthesis of guaiacyl lignin units and supply substrates for the synthesis of syringyl lignin units
physiological function
downregulation by RNAi leads to a 22.4% decrease in Klason lignin content and a 23.3% increase in cellulose content compared with wild-type. The lignin monomer composition of the RNAi plants shows a 57.08% higher S/G ratio than wild-type plants. Histological staining of lignin with Wiesner reagent produces slightly more coloration in the xylem and sclerenchyma than in wild-type plants
physiological function
-
transgenic plants of tobacco and Medicago truncatula containing the GUS gene driven by the hi12 promoter show GUS expression following harvesting
physiological function
-
the enzyme confers resistance against cadmium (Cd) in transgenic Arabidopsis thaliana. A significant increase in biomass production, Cd uptake and translocation occurs in enzyme-transfected Arabidopsis plants compared with wild type when grown under Cd stress
physiological function
ferulate is methylated from caffeoyl-CoA using S-adenosyl-L-methionine (SAM) as methyl donor catalyzed by caffeoyl CoA methyltransferase (CCoAOMT). Arabidopsis thaliana CCoAOMT7 contributes to ferulate content in the stem cell wall. CCoAOMT7 further binds to S-adenosyl-L-homocysteine hydrolase (SAHH), a critical step in SAM synthesis to release feedback suppression on CCoAOMT. CCoAOMT7 also binds S-adenosyl-L-methionine synthases (SAMSs) in vivo, which is mediated by SAHH1. Enzyme CCoAOMT7 is required for cell wall-bound ferulic esters

EXPRESSION
ORGANISM
UNIPROT
LITERATURE
CCoAOMT is downregulated in susceptible tomato following infection with the bacterium Ralstonia solanacearum
enzyme expression is induced by methyl jasmonate and XC-1 treatment
gene expression is strongly induced by harvesting and wounding but not by heat shock. The promoter of the hi12 gene contains several stress response cis-elements
-
stress treatments highly induces the expression of CCoAOMT transcripts in the stems of 3-week-old kenaf. Cold and H2O2-treated samples show the highest levels of expression at 6 and 24 h after treatment, respectively
transcript accumulation of the enzyme is detected in berry skins, and increases during berry ripening on the plant, and in cultured berries treated with abscisic acid. Drought stress increases the enzyme transcript in berries
