Common bean (Phaseolus vulgaris L.) is an important constituent of people’s diets especially in developing countries. Dry beans find a suitable position in the culinary items because of their high nutritional value. For instance, rice and bean recipe (Rajmah Chawal) is famous in the northern part of India. Many fungal, viral and bacterial diseases affect the crop and causes heavy losses worldwide. Among the various fungal diseases, bean anthracnose caused by Colletotrichum lindemuthianum is a serious disease under cool and humid environments. Under favorable conditions, the yield losses may be up to 100 percent. The scientific community across the world has been studying the bean-anthracnose interaction for over 100 years and the information has helped to understand the pathosystem and devise better disease management strategies. Many excellent reviews on anthracnose resistance genes, marker aided breeding and R gene signatures highlight different tactics for disease management. Assembling the substantial literature available on pathogen is necessary for better understanding of the pathogen biology. The present review consolidates this information and provides a comprehensive outline about the detection, pathogenicity genes, pathogenic variability and molecular diversity of C. lindemuthianum. The importance of the bean genome and availability of SNP markers to dissect the bean-anthracnose interface is also addressed.
