JAZ1 — Brassica oleracea

Summary

BoJAZ1 (JAZ1, TIFY10A) on cabbage chromosome 8 encodes a protein with a TIFY domain and carboxylesterase activity, and is annotated with 2-hydroxyisoflavanone dehydratase, isomerase, lyase, histone deacetylase, and transcription corepressor/coactivator activities, as well as core promoter and cis-regulatory region DNA binding. The gene is associated with regulation of defense responses to insects, systemic acquired resistance, jasmonic acid/ethylene-dependent systemic resistance, and downregulation of innate immunity, alongside phospholipid and isoflavonoid metabolism, ascorbate and abscisic acid biosynthesis regulation, stomatal lineage progression, seed morphogenesis, leaf morphogenesis, and filament development. It is linked to traits including anther and petal length, flower morphology, seed protein content, silique morphology, seed set, stem length, branch angle, leaf trichome density, iron concentration, and responses to sulfur, potassium, phosphorus, aluminum, temperature stress, aphids, and rice thrips damage. Studies of related genes in other species connect the family to stamen and filament development, male fertility, defense against necrotrophic pathogens, jasmonate perception, and responses to nutrient deficiency, cold, and high humidity.
