| Abstract: | A male-sterile mutant, mei-1, of Arabidopsis thaliana is described. In this mutant, instead of a tetrad of four microspores being formed after meiosis, a  tetrad consisting of from five to eight microspores is formed. The microspores show a wide range of sizes and of DNA contents. The mutant is female-fertile. This mutant was produced by seed transformation with Agrobacterium and appears to be T-DNA tagged. |
