Abstract:
... The soil-borne fungus Verticillium dahliae is causing a devastating vascular disease in more than 200 species of dicotyledonous plants. The pathogen attacks susceptible plants through the roots, colonizes the plant vascular system, and causes the death of aerial tissues. In this study, we used Arabidopsis and eggplants to examine the plant protective and immunization effects of autoclaved V. dahli ...

The red fox (Vulpes vulpes) dominates a wider ecological niche and more complicated habitat than that of the corsac fox (V. corsac). However, the adaptive mechanisms (in particular, the gut microbiome responsible for this kind of difference) are stil ...
