From: The modulation of acetic acid pathway genes in Arabidopsis improves survival under drought stress
The acetic acid biosynthesis pathway in plants. Pyruvate is converted to acetaldehyde by PDC1 and the resultant acetaldehyde is converted to acetic acid by ALDH2B7. Acetaldehyde may also be converted to ethanol and vice versa. According to Rasheed et al. (2016a), genes shown in red were up-regulated in response to drought stress, while the genes shown in blue were down-regulated. *The expression of only the mitochondrial PDH-E1 alpha (AT1G01090) and beta (AT1G30120) subunits decreased significantly in response to drought stress.
