CLP — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0316160 (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. The gene is associated with downregulation of enzyme activity, chitin, polysaccharide, protein, and chlorophyll breakdown, leaf senescence, cell death, defence responses to fungi, and shoot and root development. It localises to the apoplast and extracellular space. HvCLP is linked to photosynthetic rate, calcium, and stress. Studies of related genes in other species connect the family to grain yield, drought tolerance, disease tolerance, seed shape, starch content, plant height, root length, and leaf drying.
