Abstract

La présente invention concerne des matériaux et des procédés permettant de moduler les teneurs de lignine, la teneur de cellulose, et/ou les vitesses de croissance des plantes. Selon un aspect, l'invention concerne des matériaux et des procédés permettant de réduire les teneurs de lignine et/ou d'augmenter la teneur de cellulose et/ou d'augmenter les vitesses de croissance des plantes. Dans un mode de réalisation, un procédé selon l'invention comprend l'inhibition ou la réduction de l'expression d'un gène cpgl3 (ou d'un homologue de celui-ci manifestant essentiellement la même activité), ou l'inhibition ou la réduction de l'expression ou de l'activité de la protéine codée par un gène cpgl3, chez une plante, ladite inhibition de l'expression du gène cpgl3 ou ladite inhibition de l'expression ou de l'activité de la protéine codée par un gène cpgl3 entraînant une réduction des teneurs de lignine et/ou une augmentation des teneurs de cellulose dans la plante (par rapport aux teneurs de lignine et de cellulose de ladite plante quand il n'y a pas inhibition du cpgl3).
