Abstract
The present invention relates to rice genomic promoter sequences which promote transcription preferentially in microspores and/or pollen of plants. Also provided are chimeric genes comprising these promoter sequences, and plant transformation vectors comprising these chimeric genes. The present invention also discloses plant cells, plant tissues, plants, seeds and grains comprising these chimeric genes. The invention further discloses methods for expressing foreign nucleic acid sequences preferentially in pollen and for producing plants with modified pollen fertility.
