JAR1 — Capsicum annuum

Summary

CaJAR1 (T459_25199) on pepper chromosome 10 encodes a GH3 family protein with adenylyltransferase, IAA amido synthetase, and JA-amino synthetase activities, and is annotated with L-leucine, AMP, and amino acid binding. It is associated with jasmonic acid metabolism and signaling, cellular auxin homeostasis, anthocyanin metabolism, and regulation of defence response to bacteria. The gene is linked to plant growth hormone response, grain yield, panicle number, flower diameter, fruit length, leaf angle, photoperiod-sensitive flowering time, photosynthetic ability, and viral disease response. It has been connected to herbivore defense, chilling tolerance, bacterial resistance, salt stress response, and resistance to Fusarium graminearum. Studies of related genes in other species link the family to jasmonoyl-isoleucine biosynthesis, pathogen defense, and light signaling.
