: Being sessile organisms, plants are persistently confronted by a diverse array of biotic agents, including viruses, bacteria, fungi, herbivores and nematodes. So, understanding the mechanism of host-pathogen interactions is essential for improving plant resistance to these against biotic factors. In this review, we have discussed various means and mechanisms by which pathogens influence the host plant defense. A virulent pathogen can reduce the growth and development of a plant, which eventually lowers its yield by multiple processes, like enhancement in cell death, as well as modification of plant architecture. This review also explains the various strategies used by plants to control pathogen caused diseases. These mainly include either resistance or tolerance by activating cell signaling pathways, which further regulate the synthesis and accumulation of several cellular products, such as phytohormones, enzymes, proteins and secondary metabolites. To minimize the influence of infection on their vigor, plants also exhibit immunity regardless of the heights of pathogen multiplication. The current review provides an important insight into the mechanisms of host-pathogen interaction, which is very significant for efficient disease management.

Theory Framework

Different plant defense theories have provided important theoretical guidance in explaining patterns in plant specialized metabolism, but their critical predictions remain to be tested. Here, we systematically explored the metabolomes of Nicotiana attenuata, from single plants to populations, as well as of closely related species, using unbiased tandem mass spectrometry (MS/MS) analyses and processed the abundances of compound spectrum–based MS features within an information theory framework to test critical predictions of optimal defense (OD) and moving target (MT) theories. Information components of plant metabolomes were consistent with the OD theory but contradicted the main prediction of the MT theory for herbivory-induced dynamics of metabolome compositions. From micro- to macroevolutionary scales, jasmonate signaling was confirmed as the master determinant of OD, while ethylene signaling provided fine-tuning for herbivore-specific responses annotated via MS/MS molecular networks.
