New genetic achievements on gametophytic self-incompatibility of fruit trees
Self-incompatibility is a crucial aspect of the reproductive biology of many fruit species, and in view of its impact on fruit production it has been extensively studied by several research groups worldwide. Taking advantage of modern high-throughput technologies and multi-disciplinary approaches, recent studies provided interesting insights on many aspects related to this phenomenon, including the biochemical and cytological events underlying it, their genetic control, and the complex evolution of self-incompatibility genes in the Rosaceae. Hereby we discuss some of the most relevant results recently produced by the scientific community in this field, addressing theoretical and practical questions of fruit breeding and growing, and focusing on future research challenges.
