CLP — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0315280 (HvCLP) 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. It is associated with chitin, polysaccharide, protein and chlorophyll breakdown, proteolysis, leaf senescence, shoot and root development, cell death, defence responses to fungi, and downregulation of enzyme activity. The product localises to the apoplast and extracellular space. HvCLP is linked to photosynthetic rate and to calcium and stress responses. Studies of related genes in other species connect the family to grain yield, drought tolerance, disease tolerance, plant height, root length, seed shape, starch content, leaf drying, and net photosynthetic rate.
