COMPOSITIONS AND METHODS FOR THE EXPRESSION OF A SEQUENCE IN A REPRODUCTIVE TISSUE OF A PLANT.

摘要

Compositions and methods for regulating expression of heterologous nucleotide sequences in a plant are provided. Compositions include promoter sequences with direct expression in an egg cell or embryonic cell-preferred manner. Such compositions find use in, for example, a method for expressing a heterologous nucleotide sequence in a plant; detection of specific cell types in the ovule and targeted ablation of specific cell types.
