CLP — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0316210 (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. The gene is associated with chitin, polysaccharide, protein and chlorophyll breakdown, leaf senescence, cell death, defence response to fungi, shoot and root development, and downregulation of enzyme activity. Its product localises to the apoplast and extracellular space. HvCLP is linked to photosynthetic rate and, through related genes in other species, the family has been connected to root and lateral root development, growth, seed and starch traits, cell wall properties, disease resistance, drought tolerance, grain yield, plant height, leaf drying, leaf number, net photosynthetic rate, transpiration rate, stomatal resistance and root length.
