Abstract

A VP (Viviparous) 1 homologous gene has been cloned from wheat (Triticum aestivumL.). Its expression level was examined in the mature embryos of dormant and non-dormant cultivars. The level of expression was positively correlated with the level of seed dormancy and embryo sensitivity to abscisic acid (ABA).
