Receptor-like protein that regulates shoot meristem proliferation. Based on additive and synergistic phenotypes of double mutants, it is probable that unlike CLV1 and CLV2 in A.thaliana, FAE2 and TD1 do not function exclusively in a single pathway. Expressed in ear primordia, vegetative apex and young leaf tissues. Barely detected in expanded leaf tissues and not expressed in roots. Fasciation. Flattened and wider ears with irregular rows of seeds. Thicker rachis of tassels and increased floral organ numbers.
