Analysis of ASPAT gene family based on drought-stressed transcriptome sequencing in Vicia faba L

Fava beans（Vicia faba L.）is an important food bean crop, and drought can lead to lower fava bean yields. The identification of drought tolerance genes of fava beans is beneficial to breed the drought-resistant varieties through molecular marker-assisted breeding and genetic engineering. In a previous study, we identified a class of aspartate aminotransferase genes（ASPAT）in response to faba bean drought stress by transcriptome sequencing. ASPAT catalyzes the reversible reaction of transamination between aspartate and α-oxoglutarate to generate oxaloacetate and glutamate, and plays a key role in plant metabolism.Based on transcriptomic sequencing data, ASPAT members were identified in genome-wide level. The physicochemical properties,subcellular localizations, gene structures, protein domains, conserved motifs, phylogeny, protein interaction, and gene expression patterns of each member were analyzed. The results indicate that eight ASPAT genes were identified from the transcriptomes,which included three eukaryo
