MAZ — Capsicum annuum

Summary

CaMAZ (T459_31445) on pepper chromosome 12 encodes a PTI1-like tyrosine-protein kinase 3 with non-membrane spanning protein tyrosine kinase activity, protein kinase activity, and ATP binding. It is associated with diverse biological processes including induced systemic resistance via jasmonic acid signaling, camalexin anabolism, upregulation of reactive oxygen species anabolism, regulation of stomatal complex patterning, root hair tip growth, and pollen-pistil interaction. The gene is linked to traits such as seed size, root hair length, anther morphology, shoot axis branching, phosphorus uptake, and responses to aphids, powdery mildew, UV-B light, and osmotic stress. Localization evidence places the product at the plasmodesma, membrane, cytosol, stress granule, and preprophase band. Studies of related genes in other species connect the family to pathogen resistance, oxidative stress tolerance, and ABA sensitivity.
