Interplay of transport vesicles during plant-fungal pathogen interaction

Abstract

Vesicle trafficking is an essential cellular process upon which many physiological processes of eukaryotic cells rely. It is usually the ‘language’ of communication among the components of the endomembrane system within a cell, between cells and between a cell and its external environment. Generally, cells have the potential to internalize membrane-bound vesicles from external sources by endocytosis. Plants constantly interact with both mutualistic and pathogenic microbes. A large part of this interaction involves the exchange of transport vesicles between the plant cells and the microbes. Usually, in a pathogenic interaction, the pathogen releases vesicles containing bioactive molecules that can modulate the host immunity when absorbed by the host cells. In response to this attack, the host cells similarly mobilize some vesicles containing pathogenesis-related compounds to the pathogen infection site to destroy the pathogen, prevent it from penetrating the host cell or annul its influence. In fact, vesicle trafficking is involved in nearly all the strategies of phytopathogen attack subsequent plant immune responses. However, this field of plant-pathogen interaction is still at its infancy when narrowed down to plant-fungal pathogen interaction in relation to exchange of transport vesicles. Herein, we summarized some recent and novel findings unveiling the involvement of transport vesicles as a crosstalk in plant-fungal phytopathogen interaction, discussed their significance and identified some knowledge gaps to direct future research in the field. The roles of vesicles trafficking in the development of both organisms are also established.

“…Additionally, the extracellular space, rich in molecules for intercellular communication and environmental sensing, [ 45 ] may facilitate XIPs in detecting pathogen invasion and triggering defense responses. The presence of XIPs in vesicles, which are crucial for intracellular substance transport and secretory reactions [ 46 ] suggests their potential accumulation and/or transport to the cell wall or extracellular space through secretory mechanisms, playing a defensive role against pathogens. As xylanase inhibitors, XIPs are known to bind and inhibit xylanases from pathogens making their subcellular localizations and secretion signals vital for their biological function [ 13 ].…”

Comparative transcriptome and metabolome analysis revealed diversity in the response of resistant and susceptible rose (Rosa hybrida) varieties to Marssonina rosae

“…Vesicle trafficking plays an important role in plant defense responses. Plant cells can use vesicles to transport pathogenesis-related substances, such as proteins, nucleic acids, lipids, and metabolites, to pathogen infection sites to prevent pathogen invasion ( Abubakar et al., 2023 ). Therefore, it is speculated that the resistance of KT to M. rosae may be related to Golgi-mediated vesicle trafficking; however, the specific substances transported by the vesicles require further study.…”

“…Live-cell imaging experiments were conducted as previously described (Abubakar et al 2023 ). Briefly, the mycelia were cultured in liquid CM for 24 h. The mycelia were placed upside down on a glass slide, with the fungal hyphae directly touching the surface of the slide.…”
