MAZ — Capsicum annuum

Summary

CaMAZ (T459_31417) on pepper chromosome 12 encodes a CARK-like protein with serine/threonine and tyrosine kinase activity, protein kinase binding, and signaling receptor activity. It is associated with diverse biological processes including pollen-pistil interaction, stomatal complex patterning, root hair tip growth, induced systemic resistance via jasmonic acid signaling, camalexin anabolism, and upregulation of apoptosis and reactive oxygen species anabolism. The gene is linked to traits such as sepal morphology, seed coat morphology, adventitious root number, phosphorus uptake, wheat powdery mildew disease response, aphid response, UV-B light sensitivity, jasmonic acid sensitivity, osmotic response sensitivity, ethylene sensitivity, seed size, and shoot axis branching. 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 root hair development.
