Members of the conserved gigantea ( gi ) gene family act in the plant circadian system and regulate multiple aspects of development. The maize gigantea1 ( gi1 ) gene is the more highly expressed of two gi homeologs in the maize genome and its function is previously uncharacterized. Analysis of maize gi1 mutants demonstrates that this gene is part of the signaling networks controlling flowering time, phase change, and growth. These discoveries reveal the importance of circadian genes in the regulation of maize growth and development.
