Abstract
This study was carried out with the purpose of looking into the transcriptionally regulated genes related to the anther development, characterizing them, and applying their promoters to induce male-sterile plants and restore their fertility. Fifteen anther-specific clones were isolated from the anther cDNA library of Chinese cabbage through the differential screening and sequenced partially at both ends. These partial sequence data showed that cDNA clones BAN52, 84, 101, and 229 are very similar to polygalacturonase, ascorbate oxidase,
배추의 약(anther) 발달에 관여하는 유전자를 분리, 특성을 구명하고, 궁극적인 목표로는 특이 발현을 조절하는 프로모터를 분리 작물의 웅성불임 유기 및 임성화복에 응용하고자 본 연구를 수행하였다. 배추 약 cDNA 유전자 은행으로부터 차별화 선별(differential screening)에 의해 얻어진 15개의 약특이 유전자들의 부분 염기서열 결정 후 기존에 보고된 유전자들과 상동성 검색을 통해 그 기능을 추정해 본 결과 cDNA clone BAN52는 polygalacturonase, BAN84는 ascorbate oxidase, BAN101은
