ADF1 — Triticum aestivum

Summary

TRAESCS6B02G277600, designated TaADF1 on bread wheat chromosome 6B, encodes a protein containing the ADF/cofilin and ADF-H domains. The gene product binds both actin and F-actin, localizes to the actin cytoskeleton, F-actin, cytoplasm, nucleus, and apoplast, and is associated with actin depolymerization, catabolism, and protein modification. In wheat, the ADF7 variant has been linked to resistance against Puccinia striiformis f. sp. tritici (stripe rust). TaADF1 is associated with grain number, grain weight, grain yield per plant, spike length, plant height, days to heading, net photosynthetic rate, drought tolerance, and vascular bundle number. It is also associated with floral organ identity, seed maturation, and cytoplasmic male sterility. Related genes in other species are linked to pollen germination at high temperature and pollen tube growth.
