Abstract
Description
field of invention
[0001] The invention belongs to the field of plant genetic engineering.
[0002] The present invention mainly relates to novel DNA sequences that function as promoters of anther-specific transcription of coding DNA sequences in recombinant or chimeric DNA sequences. The invention also relates to recombinant or chimeric DNA sequences specifically expressed in plant anthers. The recombinant or chimeric DNA sequences can be used to generate transgenic plants, especially transgenic male sterile plants. Background of the invention
[0003] The production of male sterile plants is an economical hotspot in hybrid seed production. Male sterility prevents self-pollination that occurs in many plant species and hinders breeding and hybrid seed production. Anthers are male reproductive organs of flowering plants, are composed of various tissues, such as tapetum, endothecium, connective tissue, vascular tissue, etc., and are responsible for produ...
