The Paths of Plant Pathogens: Interactions with Host and Nonhosts and Insight of Mechanisms of Pathogenesis - Tapa dura

Sinopsis

Plant diseases, caused by pathogenic microbes and parasitic plants, are considered a major problem leading to great yield and economical loses. Of serious interest during recent decades are the interaction between phytopathogenic microbes and animal cross-over pathogens with their host and nonhosts and their ability to jump between them. For some pathogens, the host range is well studied, while for the others it is not. Unexpected pathogenic microorganisms can be found in unusual places and the questions is-can they switch to a pathogenic life cycle in organisms differently than their susceptible hosts? Moreover, the ability of some parasitic plants to act as vectors for phytopathogenic bacteria, viruses, and fungi is another concerning issue that warrants extensive study.

Gaining and summarizing knowledge about the molecular mechanisms that microbes use to infect host and non-host plants-or simply to use plants as natural reservoirs-is essential for identifying and managing potential environmental threats. Additionally, it is proposed that animal pathogens inhabit plants as an obligatory stage of their life cycle. Therefore, can the plant environment play a key role and stimulate the pathogen to switch into a pathogenic cycle even if it is not its natural host? Microbes are capable of adapting to new environmental niches. Our focus is on the prevalence and the ability of pathogenic organisms to moderate their mechanisms in order to expand the number of their potential hosts.
