Abstract
(EN)
The present disclosure provides modified, transgenic, or genome edited/mutated corn plants that are semi-dwarf and have one or more improved ear traits relative to a control plant, such as increase in ear area, ear diameter, ear length, green leaf number below ear, yield, single kernel weight, and/or ear fresh weight, and decrease in ear tip void. The modified, transgenic, or genome edited/mutated corn plants comprise a transgene encoding one or more proliferating cell nuclear antigen (PCNA) polypeptide and have a reduced expression of one or more GA20 or GA3 oxidase genes. Also provided are methods for producing the modified, transgenic, or genome edited/mutated corn plants.

La présente invention concerne des plants de maïs modifiés, transgéniques ou à génome édité/muté qui sont de type semi-nain et présentent un ou plusieurs caractères d'épi améliorés par rapport à un plant témoin, tels qu'un accroissement de la surface de l'épi, du diamètre de l'épi, de la longueur de l'épi, du nombre de feuilles vertes sous l'épi, du rendement, du poids des grains individuels et/ou du poids d'épi frais, et une diminution du vide de la pointe de l'épi. Les plants de maïs modifiés, transgéniques ou à génome édité/muté selon la présente invention comprennent un transgène codant pour un ou plusieurs polypeptides d'antigène de cellule nucléaire proliférant (PCNA) et ont une expression réduite d'un ou de plusieurs gènes de la GA20 ou GA3-oxydase. L'invention concerne également des procédés de production des plants de maïs modifiés, transgéniques ou à génome édité/muté.
