In one aspect, the present invention provides isolated RALF polypeptides that are useful for stimulating the growth of plant meristem cells. In another aspect, the present invention provides isolated nucleic acid molecules that are at least 90 % identical to a nucleic acid molecule (SEQ ID NO: 2) that encodes a tobacco RALF precursor polypeptide (SEQ ID NO: 3). In a further aspect, the present invention provides isolated polypeptides that are at least 90 % identical to the amino acid sequence of a tobacco RALF precursor polypeptide (SEQ ID NO: 3). In another aspect, the present invention provides vectors and plant cells comprising a vector o f the invention. In other aspects, the present invention provides methods of inhibiting meristem growth in a plant, and methods of enhancing meristem growth in a plant.
Dans un aspect, la présente invention concerne des polypeptides RALF isolés utiles pour stimuler la croissance de cellules de méristème de plantes. Dans un autre aspect, la présente invention concerne des molécules d'acides nucléiques isolées lesquelles sont identiques pour au moins 90 % à une molécule d'acide nucléique (SEQ ID NO:2) codant un polypeptide précurseur RALF du tabac (SEQ ID NO:3). Dans un autre aspect, la présente invention concerne des vecteurs ainsi que des cellules de plantes contenant un vecteur de l'invention. Dans d'autres aspects, la présente invention a trait à des méthodes d'inhibition de la croissance de méristème dans une plante, et à des méthodes d'augmentation de la croissance de méristème dans une plante.
