Maize SBP-box transcription factors unbranched2 and unbranched3 affect yield traits by regulating the rate of lateral primordia initiation.

Proceedings of the National Academy of Sciences of the United States of America - 30 Dec 2014

Abstract excerpt

The separation of male and female flowers in maize provides the potential for independent regulation of traits that affect crop productivity. For example, tassel branch number controls pollen abundance and length of shedding time, whereas ear row number directly affects kernel yield. Mutations in duplicate SBP-box transcription factor genes unbranched2 (ub2) and ub3 affect both of these yield traits. Double...
