METHOD FOR LOWERING POLLEN FERTILITY BY USING POLLEN-SPECIFIC ZINC FINGER TRANSCRIPTIONAL FACTOR GENES

摘要

A method is provided for producing a male sterile plant by utilizing a plant expression cassette including a nucleic acid which is DNA encoding zinc finger transcription factors (ZPT2-5, ZPT3-1 and ZPT4-1) derived from Petunia and a promoter operatively linked to the nucleic acid. Further, a method is provided for producing a plant having a modified trait by utilizing a plant expression cassette including a promoter derived from the ZPT3-1 and ZPT4-1 genes and a heterologous gene operatively linked to the promoter.
