Germplasm Phenotype:

• CS2110095  — style defect; minor reduction in fertility
• CS2110104  — defective style and vascular patterning of the gynoecium; increased leaf serration
• CS2110105  — defective style and vascular patterning of the gynoecium, increased leaf serration
• CS2110106  — strong gynoecial, anther, leaf and vascular defects
• CS2110107  — strong gynoecial, anther, leaf and vascular defects
• sty1-1  — When grown under long day, mutant plants were essentially the same as wild type plants, except showing some morphological aberrations restricted to the apical part of the gynoecium. Mature styles exhibited slight depression and were generally wider that in the wild type. Style epidermal cells were found at the edges of the stigma, where stigmatic papillae were formed in the WT. Papillae tent to sprawl in all directions. The outer replum is broader in mutant gynoecia. Uppermost portion of the siliques was narrowed, as a result of aborted uppermost ovules in the siliques.
• sty1-1 ett-1  — The gynoecial defects of ett-1 mutants, such as reduction in ovary size and increased gynophore elongation, were enhanced by the sty1-1 mutation. A number of double mutant gynoecia were nearly completely valveless, and in those, ovules grew on top of a placental surface. In addition, the apical ends of sty1-1 ett-1 gynoecia were less fused than those of ett-1 and sty1-1, and ovules frequently protruded at the apex. The amount of stylar and stigmatic tissues was reduced compared with ett-1, and the double mutant was sterile. As in ett-1 gynoecia, ectopic tissue of transmitting tract identity was generally present.
• sty1-1 pin1-5  — enhanced phenotype of pin1-5 single mutant, the valves of mutant gyneoecia were reduced and often fused along one of the margins.
• sty1-1,sty2-1, shi-2, shi-3, lrp1  — 18-25% of flowers have homeotic conversion petals/anthers with fused characteristics. Anther locules are abnormal. Tapetal development is abnormal with reduced pollen viability.
