Characterization and expression of the gene family in .

Pirins are nuclear bicupin proteins, encoded by genes that are one of several gene families that comprise the cupin superfamily in plants. genes have been implicated in stress response pathways studied in Arabidopsis and At- has been shown to interact with the heterotrimeric G-protein alpha subunit (GPA1). The aim of this study was to identify the members of the gene family in to correct their annotations in the whole genome, and gain an insight into their tissue-specific expression as well as their response to abiotic and biotic stresses. The gene family in is comprised of 18 genes that represent six paralogous gene copies, each having an A, B, and D homeolog. Expression analysis of the genes in Illumina RNA-seq libraries, which included sampling from differing tissue types as well as abiotic and biotic stresses, indicates that the members of the gene family have specialized expression and play a role in stress responses. gene families are also identified in other monocots including , and the dicot
