Has Phenotype yes
Description In a wild type floret the overlapping lemma and palea form glumes with six stamens and a pistil inside. In contrast, a mutant floret has degenerated lemma and palea, so that they fail to enclose the stamens and pistil. The mutant does not produce normal stamens and is thus male sterile. Usually, one floret forms one caryopsis. Although mutant is male sterile, it can produce seeds when pollinated with pollen from wild type plants. In that case one or two naked seeds can be formed in a single floret. So, the mutant is female fertile. In general, a mutant floret contains many pistils but no stamens, indicating that the stamens are transformed to pistils. In some mutant florets, pistilloid stamens containing a filament tipped by malformed tissue and deformed stigma or one to three stigmas were observed. In the cross section of a wild type floret six filaments representing the six stamens and an ovary representing the pistil in the middle can be seen clearly, while in a mutant floret, some filaments and some pistilloid tissues, e.g., the ovary-like or malformed tissues are observed. The pistilloid tissues are counterparts of the wild type stamens. In the longitudinal section of a mutant floret, three ovaries can be seen clearly.
