Resumo: | Sugarcane is one of the important commercial crops cultivated world-wide both under tropical and sub-tropical conditions. The crop gains economic importance by virtue of its industrial potential in terms of products like crystal white sugar, bagasse, pressmud, power etc. Among the various production constraints of the crop, diseases are seen as a major threat for sustaining the productivity of sugarcane. Conventional Breeding is a lengthy process and it involves almost more than 10 years for the release of a commercial variety. Many varieties with superior agronomical traits have succumbed to diseases like red rot and smut during the course of cultivation, which hitherto at the time of release were rated to be resistant. The breakdown of disease resistance is attributed to the possible emergence of new virulent pathotypes. This situation has warranted a pertinent need to have a thorough understanding on inheritance pattern and mechanism of disease resistance in sugarcane, which would aid for quick screening of disease resistant clones and successful management of the diseases, respectively. Overall, there is a paradigm shift in the understanding of plant disease resistance, thanks to the advent of robust molecular tools. An integration of the tools of “Omics” namely genomics, proteomics, metabolomics etc. has further strengthened in deciphering plant-pathogen interactions at the molecular level. With the accomplishments in elucidating sugarcane ESTs, which was ably supported by employing the next generation sequencing platforms to unlock the secrets of pathogenomics in sugarcane, it is now made possible to further improve our understanding on disease resistance in sugarcane. Giving the scenario, the future looks evenmore promising, wherein convincing results are in the offing to thoroughly unravel the enigmatic relationship between sugarcane and its important pathogens.
