Rosetteness in Portulaca grandiflora: an altered genetic expression.
Rosetteness is either developmentally controlled or induced by various biotic and abiotic stresses. Prolonged vegetative growth and/or pruning seems to be inducing rosetteness in Portulaca grandiflora. Analysis of cellular extracts from rosette stems by SDS-PAGE, revealed induction of a polypeptide of high molecular mass (approximately equal to 58 kDa) and over-expression of a few lower molecular weight polypeptides. However, leaves showed no differences in the protein profiles.
