New plant promoters providing albumen-specific expression, useful for preparing transgenic plants with altered starch and oil contents

摘要

Isolated promoter (P) provides expression of attached sequences that is specific to the region of albumen surrounding the embryo in Angiosperm seeds and active in the early stages of albumen development. Independent claims are also included for the following: (1) expression cassette (EC) comprising P operably linked to at least one gene of interest (I); (2) expression vector (EV) containing EC; (3) host cells (I), from an Angiosperm, especially a cereal plant, transformed with EV; (4) transgenic plant (II), or part, produced from (I); (5) transgenic hybrid plant produced by crossing (II); and (6) production of an Angiosperm plant with improved agronomic and/or nutritional properties by transformation with EV.
