ABSTRACT
Short-chain dehydrogenase/reductase (SDR) belongs to the NAD(P)(H)-dependent oxidoreductase superfamily. Limited investigations reveal that SDRs participate in diverse metabolisms. A genome-wide identification of the SDR gene family in M. truncatula was conducted. A total of 213 MtSDR genes were identified, and they were distributed on all chromosomes unevenly. MtSDR proteins were categorized into seven subgroups based on phylogenetic analysis and three types including 'classic', 'extended', and 'atypical', depending on the cofactor-binding site and active site. Analysis of the data from M. truncatula Gene Expression Atlas (MtGEA) showed that above half of MtSDRs were expressed in at least one organ, and lots of MtSDRs had a preference in a tissue-specific expression. The cis-acting element responsive to plant hormones (salicylic acid, ABA, auxin, MeJA, and gibberellin) and stresses were found in the promoter of some MtSDRs. Many genes of MtSDR7C,MtSDR65C, MtSDR110C, MtSDR114C, and MtSDR108E families were responsive to drought, salt, and cold. The study provides useful information for further investigation on biological functions of MtSDRs, especially in abiotic stress adaptation, in the future.
