Abstract

A novel gene, denoted IbEF1isolated from sweet potato corresponded to the most abundant mRNA present in root tissue under salt stress. However, the encoded protein did not accumulate in the shoots. Transgenic tobacco plants were generated to elucidate the physiological function of IbEF1. The extent of early flowering of these plants correlated well with the level of IbEF1 expression, implicating IbEF1 as a positive regulator of flowering of tobacco plants. Over-expression of IbEF1 enhanced the AP1 gene in response to flowering time, but not floral organ development. These results demonstrate that simple manipulation of IbEF1 activity has great potential with regard to flowering time.
