CLP — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0316130 (HvCLP) on barley chromosome 3H encodes a protein with xylanase inhibitor I-like and aspartic peptidase A1 domains, and is annotated with chitinase, aspartic endopeptidase, enzyme inhibitor, nutrient reservoir and IgE-binding activities. It is associated with chitin, polysaccharide, protein and chlorophyll breakdown, leaf senescence, shoot and root development, cell death, defence responses to fungi, and downregulation of enzyme activity. The protein localises to the apoplast and extracellular space. HvCLP is linked to photosynthetic rate and, through related genes in other species, the gene family has been connected to root and shoot development, seed and starch traits, grain yield, drought tolerance, and disease resistance.
