U of I Research Makes Plant Breeding Easier

The loss of function of RF1A1/ALDH2B2, a fertility restorer (RF) protein causes maize susceptibility to Helminthosporium maydis, the causal agent that was responsible for the maize southern corn leaf blight epidemic in 1972. The disease symptoms on a maize leaf, the spore of the H. maydis and the secondary structural feature of the maize fertility restorer protein are here depicted. From the first case of southern corn leaf blight disease up to date, it has taken us up to 38 years to finally catalog the entire fertility restorer proteins in higher plants. The University of Illinois is pleased to release the new and universal nomenclature of RF proteins to advance research work on fertility restorer proteins in plants.
