Conteúdo: | Common bean (Phaseolus vulgaris L.) is the world's most important food legume for direct human consumption. This new world crop is adapted to many niches and it is grown in distinct regions and different seasons around the world. The common bean crop is grown by subsistence levels farmers with little technology as well as by farmers in developed nations that use high input technologies. Unfortunately, common bean yields are quite low compared to other grain legumes; e.g., soybeans and peas. One of the several factors contributing to this situation is the high number of pathogens that cause common bean diseases. Among these diseases is the common bean rust, incited by the basidomycete fungus Uromyces appendiculatus F. Strauss (syn. U. Phaseoli G. Winter), which can cause great yield losses. We present here relevant information about the common bean rust including its etiology, epidemiology, the rust pathogen infection process, the symptomatology and genetic diversity of the pathogen. We also review progress on the control of the disease using cultural practices, biological and chemical methods. It is also reported and discussed the host resistance and pathogen specialization, genetics of host-pathogen interactions, the available molecular markers linked to rust resistance genes, and its utilization in marker assisted selection (MAS) for the development for rust resistance cultivars.
