Abstract:
... Lettuce, Lactuca sativa, is one of the main leafy vegetable crops, interesting as a source of phytonutrients. It is extensively studied for biotechnological applications based on in vitro regeneration. However, in lettuce, histological studies of adventitious morphogenesis during the regeneration process are lacking. Analogously, the genes involved in the initiation of adventitious shoots or embry ...
