Quantitative real-time PCR was used to monitor the expression of 15 's genes, putatively involved in pathogenicity, highly (HAV) and weakly aggressive (WAV) isolates after either (i) elicitation with potato leaf, stem, or root extracts, or (ii) inoculation of potato detached petioles. These genes, i.e., coding for Ras-GAP-like protein, serine/threonine protein kinase, Ubiquitin-conjugating enzyme variant-MMS2, NADH-ubiquinone oxidoreductase, Thioredoxin, Pyruvate dehydrogenase E1 VdPDHB, myo-inositol 2-dehydrogenase, and HAD-superfamily hydrolase, showed differential upregulation in the HAV versus WAV isolate in response to plant extracts or after inoculation of potato leaf petioles. This suggests their potential involvement in the observed differential aggressiveness between isolates. However, other genes like glucan endo-1,3-alpha-glucosidase and nuc-1 negative regulatory protein showed higher activity in the WAV than in the HAV in response to potato extracts and/or during infection. This, in contrast, may suggest a role in their lower aggressiveness. These findings, along with future functional analysis of selected genes, will contribute to improving our understanding of 's pathogenesis. For example, expression of negatively regulates phosphorus-acquisition enzymes, which may indicate a lower phosphorus acquisition activity in the WAV. Therefore, integrating the knowledge about the activity of both genes enhancing pathogenicity and those restraining it will provide a guild line for further functional characterization of the most critical genes, thus driving new ideas towards better Verticillium wilt management.

Plants respond to attacks by insects by releasing herbivore-induced plant volatiles (HIPVs), which are known to influence the behavior of natural enemies, conspecific and heterospecific insects. However, little is known about how HIPVs induced by one insect species influence the behavior of an allospecific insect species, particularly if these insects belong to different feeding guilds. Here, using the interaction of two co-occurring insects with different feeding guilds - Bemisia tabaci (a sap sucking insect) and Tuta absoluta (a leaf mining insect) - on potato plants, we report that T.

Bacterial soft rot causes major crop losses annually and can be caused by several species from multiple genera. These bacteria have a broad host range and often infect produce through contact with soil. The main genera causing bacterial soft rot are and , both of which have widespread geographical distribution.

Plant viruses are naturally occurring nanoparticles and adjuvants that interact with the mammalian immune system. This property can be harnessed in vaccines and immunotherapy. We have previously demonstrated that intratumoral immunotherapy with cowpea mosaic virus (CPMV) stimulates systemic and durable antitumor immunity in mouse tumor models and canine cancer patients.

Potato virus Y (PVY, Potyviridae) is among the most important viral pathogens of potato. The potato resistance gene Ny confers hypersensitive resistance to the ordinary strain of PVY (PVY), but not the necrotic strain (PVY). Here, we unveil that residue 247 of PVY helper component proteinase (HCPro) acts as a central player controlling Ny strain-specific activation.
