CCT — Zea mays

Summary

ZM00001EB404370, designated ZmCCT, encodes a Med12b subunit of the Mediator complex, functioning as a transcriptional co-regulator. This maize gene on chromosome 9 is associated with photoperiodism and flowering time, as well as temporal regulation of development, vegetative phase change, and the juvenile-to-adult transition. It has been linked to agronomically important traits including grain yield, grain weight, ear diameter and length, plant height, leaf number, anthesis time, root length, and tolerances to heat, drought, and salt. Additional associations include carbohydrate and glucose homeostasis, SAM development, cell cycle control, and systemic acquired resistance. The encoded protein localises to the nucleus and Mediator complex. Studies of related genes in other species connect the family to flowering time, root architecture, germination, and cold response.
