JAZ6 — Triticum aestivum

Summary

TRAESCS2D02G176800, designated TaJAZ6 (also TaTIFY10B-2D), encodes a TIFY/JAZ family protein on bread wheat chromosome 2D. The gene is associated with regulation of jasmonic acid-mediated signaling, defense responses, anther development, and protein processing. It has been linked to sucrose metabolism, nitrate response, karrikin response, abiotic stimulus response, and positive regulation of flavonoid anabolism. Localization evidence connects the product to the cytosol, nucleus, and plasmalemma. TaJAZ6 is associated with agronomically important traits including grain weight, grain yield, harvest index, plant height, root length, starch content, lignin content, and male sterility. Coexpression studies and pathway associations link the gene to jasmonic acid biosynthesis, glutathione biosynthesis, sterol biosynthesis, and chorismate biosynthesis. Studies of related genes in other species connect the family to floret number, culm length, spikelet fertility, grain size, and salt tolerance.
