CLP — Hordeum vulgare subsp. vulgare

Summary

HvCLP (HORVU.MOREX.R3.3HG0316120) on barley chromosome 3H encodes a protein with xylanase inhibitor I-like and aspartic peptidase A1 domains, annotated with chitinase, aspartic endopeptidase, enzyme inhibitor, nutrient reservoir, and IgE binding activities. The gene is associated with chitin, polysaccharide, protein, and chlorophyll breakdown, leaf senescence, shoot and root development, cell death, defense response to fungi, and downregulation of enzyme activity. It localizes to the apoplast and extracellular space. HvCLP is linked to photosynthetic rate and, through studies of related genes in other species, the family has been connected to grain yield, drought tolerance, disease tolerance, seed shape, starch content, plant height, root length, and stomatal resistance.
