Phenotype

Defective in floral organ identity and organ number; late-arising flowers exhibited more severe phenotypes than early-arising flowers; in the late-arising flowers, the organ number in whorls 2 and 3 is reduced; on average, only 3 organs are found in whorl 2, and 5 organs in whorl 3; 7% of whorl 1 organs display partial homeotic transformation and possess sepal/petal or sepal/carpel mosaics; whorl 2 organs are most often narrow petals, but stamenoid petals were occasionally observed; alternatively, petals can be replaced by filamentous or tubular structures; whorl 3 stamens are typically reduced slightly in size; the whorl 4 gynoecium is often slightly split at the top; sometimes, horn-like protrusions are seen at the gynoecium apex. Narrow floral organs; narrow leaves; reduced plant height (semi dwarf); increased lateral branching; reduced number of seeds per silique.
