Molecular Characterization and Expression Profiling of Brachypodium distachyon L. Cystatin Genes Reveal High Evolutionary Conservation and Functional Divergence in Response to Abiotic Stress.

ABSTRACT: Cystatin is a class of proteins mainly involved in cysteine protease inhibition and plant growth and development, as well as tolerance under various abiotic stresses. In this study, we performed the first comprehensive analysis of the molecular characterization and expression profiling in response to various abiotic stresses of the cystatin gene family in Brachypodium distachyon, a novel model plant for Triticum species with huge genomes. Comprehensive searches of the Brachypodium genome database identified 25 B. distachyon cystatin (BdC) genes that are distributed unevenly on chromosomes; of these, nine and two were involved in tandem and segmental duplication events, respectively. All BdC genes had similar exon/intron structural organization, with three conserved motifs similar to those
