Genome-Wide Identification and Expression Analysis of the Aux/IAA Gene Family in Lettuce (<i>Lactuca sativa</i> L.).

ABSTRACT: The Aux/IAA proteins are key regulators of auxin signaling transduction, mediating various physiological and developmental processes in higher plants; however, little information on Aux/IAAs is known in lettuce, an economically important vegetable. In this study, a total of 29 LsAux/IAA genes were identified from the lettuce genome. Sequence alignment and domain analyses suggested the presence of conserved Aux/IAA subdomains (Domain I-IV) in those LsIAAs, and Phylogenetic analysis indicated that members of LsAux/IAA could be classified into 10 subgroups by their homology to Arabidopsis Aux/IAAs, which is also supported by exon-intron structure, consensus motifs, and domain compositions. Transcriptome data suggested that most of the LsIAA genes were expressed in all tis
