The present invention relates to isolated nucleic acid molecules and their corresponding encoded polypeptides able to confer the trait of altered flowering time in plants. The present invention further relates to using the nucleic acid molecules and polypeptides to make transgenic plants, plant cells, plant materials or seeds of a plant having flowering times that are altered with respect to wild-type plants grown under similar conditions. Altered flowering time includes both plants having an early flowering time and a late flowering time with respect to wild-type plants grown under similar conditions. Flowering time in plants may be altered either with respect to the normal time at which wild-type plants flower within their normal life cycle or altered temporally such that the entire life cycle of the plant is accelerated or prolonged using the nucleic acid molecules and polypeptides of the present invention.
