Germplasm Phenotype:

• CS16305  — No visible phenotype.
• CS16306  — No visible phenotype
• CS31092  — No visible mutant phenotype.
• bam1-1 bam2-1  — Anthers in double mutant plants appeared abnormal at a very early stage and lack the endothecium, middle, and tapetum layers. Further analyses revealed that cells interior to the epidermis (in anther tissue) acquire some characteristics of pollen mother cells (PMCs), suggesting defects in cell fate specification. The pollen mother-like cells degenerate before the completion of meiosis, suggesting that these cells are defective.
• bam1-1 bam2-1  — Reduced shoot meristem size.
• bam1-1 bam2-1 bam3-2  — Plants arrest early in development due to loss of shoot apical meristem but recover through adventitious shoot formation.
• bam1-1 bam2-1 bam3-2  — Reduced numbers of stamens and carpels suggesting a reduction in floral meristem size.
• bam1-1/bam2-1/clv1-11  — Triple mutant enhances the floral meristem defects of clv1-11 single mutant. Novel phenotypes include the existence of an enlarged indeterminate meristem in the center of each flower. Leaves are smaller and number of rosette leaves is increased.
• bam1-1/bam2-1/clv2-1  — Number of carpels not statistically significant form that of clv2-1 alone.
• bam1-1/bam2-1/clv3-2  — Triple mutant shows greater suppression of the clv3-2 with approximately 4.3 carpels per flower compared to clv3-2 single mutants which have approximately 6.7 carpels per flower.
• bam1-3 bam2-3  — Altered leaf morphology: fewer veins than wild type and a distinct lack of higher-ordered veins.
• bam1-3 bam2-3  — Anthers in double mutant plants appeared abnormal at a very early stage and lack the endothecium, middle, and tapetum layers. Further analyses revealed that cells interior to the epidermis (in anther tissue) acquire some characteristics of pollen mother cells (PMCs), suggesting defects in cell fate specification. The pollen mother-like cells degenerate before the completion of meiosis, suggesting that these cells are defective.
• bam1-3 bam2-3  — Delayed in development: smaller in size and bolt and flower later than wild-type plants.
• bam1-3 bam2-3  — Floral organ defects.
• bam1-3 bam2-3  — Higher degree of branching in plants and have a longer lifespan. Almost completely sterile.
• bam1-3 bam2-3  — Reduced shoot meristem size.
• bam2-1  — No visible phenotype.
• bam2-1/clv3-2  — Reduced number of carpels relative to clv3 single mutant.
• bam2-3  — No visible phenotype.
