(EN) SEED PLANTS CHARACTERIZED BY DELAYED SEED DISPERSAL
(FR) PLANTES A GRAINES CARACTERISEES PAR UNE DISSEMINATION RETARDEE DES GRAINES
Abrégé
(EN)
The present invention provides a non-naturally occurring seed plant that is characterized by delayed seed dispersal due to ectopic expression of a nucleic acid molecule encoding an AGL8-like gene product. Further provided herein is a non-naturally occurring seed plant, such as an $i(ag11 ag15) double mutant, that is characterized by delayed seed dispersal due to suppression of AGL1 and AGL5 expression in the seed plant. The invention also provides a substantially purified dehiscence zone-selective regulatory element, which includes a nucleotide sequence that confers selective expression upon an operatively linked nucleic acid molecule in the valve margin or dehiscence zone of a seed plant. Also provided by the invention are kits for producing a transgenic seed plant characterized by delayed seed dispersal, such kits containing a dehiscence zone-selective regulatory element.
(FR)
L'invention concerne une plante à graines n'existant pas à l'état naturel et caractérisée par une dissémination retardée des graines, qui est due à l'expression ectopique d'une molécule d'acide nucléique codant pour un produit génique semblable à AGL8. Elle concerne également une plante à graines n'existant pas à l'état naturel, telle qu'un double mutant $i(ag11 ag15), caractérisée par une dissémination retardée des graines, qui est due à la suppression d'AGL8 et d'AGL1 dans la plante à graines. En outre, l'invention concerne un élément régulateur sensiblement purifié à sélection de zone de déhiscence contenant une séquence nucléotidique qui attribue l'expression sélective à une molécule fonctionnellement liée d'acide nucléique dans la zone de bord de valve ou de déhiscence d'une plante à graines. L'invention se rapporte enfin à des kits permettant de créer une plante à graines transgénique caractérisée par une dissémination retardée des graines, lesdits kits comprenant un élément régulateur à sélection de zone de déhiscence.
