JAR1 — Solanum tuberosum

Summary

StJAR1 (PGSC0003DMG401000095) on potato chromosome 1 encodes a GH3 family protein with adenylyltransferase, IAA amido synthetase, and JA-amino synthetase activities, and binds L-leucine, AMP, and amino acids. It is associated with jasmonic acid metabolism and anabolism, cellular auxin homeostasis, anthocyanin and glutathione metabolism, and regulation of defence responses to bacteria. The gene is linked to wound healing, response to mycotoxin, and regulation of response to red or far red light. Associations include plant growth hormone response, grain yield, panicle number, flower diameter, leaf angle, photosynthetic ability, photoperiod-sensitive flowering time, reducing sugar content, viral disease response, and chilling tolerance. It is also connected to herbivore defence, insect resistance, bacterial resistance, salt stress response, root growth, and lignin deposition.
