Duckweed (Lenna) is associated with which resistance mechanism?

Duckweed, a small floating aquatic plant, has developed a resistance mechanism primarily associated with carotenoid biosynthesis inhibitors. These inhibitors target the synthesis of carotenoids, which are essential for protecting plants from oxidative stress and damage caused by light. The ability of duckweed to withstand these herbicides indicates that it has adapted its biochemical pathways to either bypass or tolerate the effects of such chemicals.

By understanding this resistance mechanism, it becomes clear why targeted management strategies should consider the specific herbicide classes that may be ineffective against duckweed. This knowledge is crucial for effective aquatic weed control and emphasizes the importance of comprehensively assessing herbicide choices and their potential impact on specific plant species.
