LAP1 — Cicer arietinum

Summary

CaLAP1 (LOC101488227) on chickpea chromosome 7 encodes a leucine aminopeptidase (LAP) family protein with metalloaminopeptidase, dipeptidase, and protease activities, along with manganese and magnesium binding, protein dimerization, and DNA-binding transcription factor activity. It is associated with proteolysis, peptide breakdown, protein hexamerization, proanthocyanidin and anthocyanin anabolism, seed germination, flower development, and responses to jasmonic acid, wounding, heat, low humidity, insects, and bacteria. The gene is linked to guard cell fate commitment, guard mother cell differentiation, and upregulation of cell differentiation and transcription. Localization evidence connects it to the vacuole, chloroplast stroma, cytosol, plasma membrane, cytoplasm, and nucleus. Associations with seed coat color, vegetative growth, stress tolerance, leaf senescence, guard cell development, stomatal differentiation, immunity to Botrytis cinerea, and root gravitropism have been noted. Related genes in other species link the family to stress response, heat tolerance, glutathione degradation, and stomatal development.
