CC -!- FUNCTION: Probable RNA-binding protein. Involved in the regular timing
CC (plastochron) of lateral organs formation. May regulate the rate of
CC leaf initiation and the duration of vegetative phase. Seems to be
CC redundant to the function of PLASTOCHRON1, but to act in an independent
CC pathway. {ECO:0000269|PubMed:16541125}.
CC -!- TISSUE SPECIFICITY: Highly expressed in shoot apex and inflorescence
CC apex, at intermediate levels in roots and at low levels in leaf blade
CC and leaf sheath. {ECO:0000269|PubMed:16541125}.
CC -!- DISRUPTION PHENOTYPE: Plants produce threefold the number of leaves,
CC and leaf size and plant height are strongly reduced compared to wild-
CC type. Shoot apical meristem (SAM) shows a higher rate of cell division
CC and internode elongation is significantly reduced. Some inflorescence
CC branches are converted into vegetative shoots.
CC {ECO:0000269|PubMed:16541125}.
CC -!- MISCELLANEOUS: Plastochron is defined as the time interval between leaf
CC initiation events.
