MAZ — Capsicum annuum

Summary

CaMAZ (T459_32730) on pepper chromosome PGAv.1.6.scaffold960 encodes a CARK-like protein with protein tyrosine kinase activity, protein serine/threonine kinase activity, transcription factor binding, phosphatase binding, and protein homodimerization activity. It is associated with diverse biological processes including nitrogen fixation, pollen-pistil interaction, stomatal complex patterning, root hair tip growth, camalexin biosynthesis, induced systemic resistance via jasmonic acid signaling, and upregulation of apoptosis and reactive oxygen species production. The gene has been linked to traits such as sepal and seed coat morphology, adventitious root number, anther morphology, phosphorus uptake, aphid response, UV-B light sensitivity, ethylene sensitivity, seed size, and wheat powdery mildew disease response. Localization evidence places the product at the plasmodesma, membrane, cytosol, stress granule, and trans-Golgi network. Studies of related genes in other species connect the family to drought resistance, pathogen defense, oxidative stress tolerance, and stomatal aperture regulation.
