NASC Stock Detail Page

NASC ID: N6395

Name: rbe-1

ABRC stock number: CS6395

Description: Defective in petal development; the degree of morphological abnormality of petals varies from: a mild phenotype of a reduced blade at the top, an intermediate phenotype of spoon shaped petals with a small blade and a short filamentous stalk at the base, to a severe phenotype of filaments only; in some caes no petals or filaments are observed at the position of petal formation; ovules have shorter integuments than those of wild type, producing shorter siliques; reduced fertility.

Phenotype

Altered petal morphology. A wild-type flower has four petals of almost the same size and shape. A petal is flat from top to bottom, and the bottom part is narrow and greenish. In rbe-1, petals were deformed and their degree of morphological abnormality varied from a mild phenotype of a reduced blade at the top, an intermediate phenotype of spoon-shaped petals with a small blade and a short filamentous stalk at the base, to a severe phenotype of filaments only. In some cases, no petals or filaments were observed at the position of petal formation.<p>The epidermal cells on the lower surface of the filaments of rbe-1 had an irregular ridged structure similar to that of the lower surface of the wild type, but the cells were flattened and elliptic. The position of the filamentous petals was normal; that is, they were formed in the second whorl at a position between the medial and lateral sepals. Furthermore, in the small or spoon-shaped petals of rbe-1, the epidermal cells had a ridged structure and were smaller . This suggests that the position and identity of the aberrant-shaped petals of rbe was not altered.
