XTH1 — Cicer arietinum

Summary

CaXTH1 (LOC101512824) on chickpea chromosome 7 encodes a member of the xyloglucan endotransglucosylase/hydrolase (XTH) family, possessing endoxyloglucan transferase and O-glucosyl hydrolase activities, and belongs to the GH16 beta-glucanase domain family. The gene is associated with xyloglucan and cellulose metabolism, plant-type cell wall biogenesis, secondary cell wall biogenesis, cell wall organization, and cell differentiation, including epidermal cell differentiation and root hair initiation. It has also been linked to ethylene anabolism, photoperiodism and flowering, fruit ripening, and vesicle transport. The encoded protein localizes to the apoplast, plant-type cell wall, extracellular region, and cytoplasm. Related genes in other species link the family to cellulose cross-linking.
