Potato (Solanum tuberosum L.) is the fourth significant and the most consumed staple crop after rice, wheat and corn in the world. It is known that several biotic stresses cause reduction in worldwide potato yields, which in turn, leads to a significant economic loss. In biotic stress response, potato plants have developed a wide range of defense and damage-delimiting mechanisms. Morphological, biochemical, physiological and agronomical trait response screening studies on potato stress response are available to characterize the parameters from both pathogen and host sides. However, molecular studies to identify candidate biotic stress-associated genes are limited. For understanding and identification of biotic stress responsive plant genes, several approaches, such as RNA-seq-based gene expression profiling, gene expression microarray and transcriptome analyses give an insight to the molecular mechanisms of biotic stress tolerance in potato. Comprehending of plant-herbivore and plant-pathogen mechanisms in plant defense responses will be effective to protect plants against biotic stresses, and to develop cultivars with higher stress tolerance. Here, we present the current molecular studies of potato responses under biotic stresses.
