Abstract

Selon l'invention, il a été découvert que la 4-coumarate-CoA ligase (4CL) était essentielle pour la croissance des plantes. En particulier, l'inhibition de l'expression du gène de la 4CL dans des semis de plantes entraîne une réduction et un arrêt de la croissance. La 4CL peut ainsi être utilisée en tant que cible pour l'identification d'herbicides. L'invention concerne des procédés d'identification de composés qui inhibent l'expression ou l'activité de la 4CL, qui comprennent les étapes consistant: à mettre en contact un composé avec de la 4CL et à détecter la présence et/ou l'absence de liaison entre ledit composé et ladite 4CL; ou à détecter une baisse d'expression ou d'activité de la 4CL. Les procédés de l'invention sont utiles pour l'identification d'herbicides.
