Arabidopsis thaliana | exogenous nicotinic acid methyl ester, nicotinate and nicotinamide treatment does not obviously affect the transcript levels of NaMT1 | additional information |
Arabidopsis thaliana | abiotic stress (salt, abscisic acid, and mannitol) treatments induce the expression of NaMT1 | up |
General Information | Comment | Organism |
---|---|---|
physiological function | the transfer of nictotinic acid methyl ester from the root to leaf is significantly increased in both methyl esterase MES2 knockdown and NaMT1-overexpressing lines. NaMT1-overexpressing plants have longer roots than wild-type plants under nicotinic acid treatment | Arabidopsis thaliana |
