Evolutionary and expression study of the aldehyde dehydrogenase (ALDH) gene superfamily in rice (Oryza sativa)

Expression Profiles of Stress Responsive Genes in Rice (Oryza Sativa L.) Under Abiotic Stresses

“…transcription of Arabidopsis thaliana ALDH3I1 gene was induced by osmotic and oxidative stresses and overexpression of ALDH3I1 conferred stress tolerance in transgenic plants (12). Up-regulation of some ALDH genes by drought and high salinity stresses and ABA application was reported in rice, indicating that ALDH genes are involved in osmotic stress tolerance (8,9). it was also reported that expression of OsAldh2a was induced under anaerobic conditions in rice (1).…”

“…Genes involved in alcohol fermentation are known to respond to abiotic stresses. transcripts of ADH (alcohol dehydrogenase) and ALDH (aldehyde dehydrogenase) genes, which are involved in alcohol fermentation, are accumulated in response to abiotic stresses in rice and Arabidopsis thaliana (1,5,8,12,18,28). Abscisic acid (ABA) is a phytohormone regulating various abiotic stress responsive pathways (36).…”

Mutation of OsALDH7 causes a yellow-colored endosperm associated with accumulation of oryzamutaic acid A in rice

“…-dependent enzymes that oxidize aldehydes into their corresponding carboxylic acids (Vasiliou et al 1999;Sophos et al 2001;Sophos and Vasiliou 2003). ALDH comprises at least 22 families according to protein sequence identity, and plays derivate functions based on their substrates (Marchitti et al 2008;Gao and Han 2009). In human, most of ALDHs have been well investigated.…”

“…In plant, 12 families, including ALDH2, ALDH3, ALDH5, ALDH6, ALDH7, ALDH10, ALDH11, ALDH12, ALDH18, ALDH19, ALDH21 and ALDH22, have been documented, but only few of them have been studied in detail (Kirch et al 2004;Gao and Han 2009). RF2, an ALDH2 homolog in maize, functions as a restorer for male fertility (Liu et al 2001).…”

“…Mutation of ALDH7A1 results in the disruption of neurotransmitter metabolism and causes serious seizures (Mills et al 2006). As yet, the expressions of ALDH7 in plants such as garden pea, brassica, apple, tortula ruralis, sorghum and Arabidopsis were found to be associated with seed maturation and osmotic stress response (Kirch et al 2005;Gao and Han 2009). However, their exact molecular mechanisms still remain to be clarified.…”
