Comparative study of the aldehyde dehydrogenase (ALDH) gene superfamily in the glycophyte Arabidopsis thaliana and Eutrema halophytes.

ABSTRACT:

Background and aims

Stresses such as drought or salinity induce the generation of reactive oxygen species, which subsequently cause excessive accumulation of aldehydes in plant cells. Aldehyde dehydrogenases (ALDHs) are considered as 'aldehyde scavengers' to eliminate toxic aldehydes caused by oxidative stress. The completion of the genome sequencing projects of the halophytes Eutrema parvulum and E. salsugineum has paved the way to explore the relationships and the roles of ALDH genes in the glycophyte Arabidopsis thaliana and halophyte model plants.

Methods

Protein sequences of all plant ALDH families were used as queries to search E. parvulum and E. salsugineum genome databases. Evolutionary analyses compared the phylogenetic relationships of ALDHs from A. thaliana and Eu
