CS65826 — Extra petals in early-arising flowers due to a loss of function of miR164c, which leads to increased levels of CUC1 and CUC2.
CS65828 — Slightly increased leaf serration during vegetative development; increased number of sepals and petals during reproductive development; irregular flower arrangement due to repressed cell division in the internodes that separate individual flowers.
CS65837 — No visible phenotype.
eep1 — Flowers have more petals than the wild-type, particularly in the first 10 flowers. Four petal primordia are initiated in the same positions as in wild-type. The extra petals, if initiated, always arise adjacent to these normally positioned petals. Occasionally, petals form incisions at their distal tip and adopt a heart shape. There is also a subtle carpel fusion defect at the distal end of the gynoecium in a small portion of mutant flowers. The organ-number defect is petal specific. In mutant plants, the transcript levels of the transcription factors CUC1 and CUC2 are significantly increased compared to wild-type. Overall expression domains of CUC1 and CUC2 appear to be normal. However, during floral stages 5-7, extra CUC1- and CUC2-expressing cells are observed in the second whorl.
mir164abc — Plants appear normal during vegetative growth. Phenotypic alterations start after the switch to reproductive development. Flowers have an increased number of sepals and petals. Floral organ numbers are highly variable. Individual organs varied in size. Carpels failed to fuse resulting in severe reduction of fertility. In addition, plants display a highly unequal and distorted arrangement of flowers, both with respect to the angle formed by two consecutive flowers and their distance from each other along the axis of the stem.
