Abstract:
... Vegetative incompatibility (VI) is a form of non-self allorecognition in filamentous fungi that restricts conspecific hyphal fusion and the formation of heterokaryons. In the chestnut pathogenic fungus, Cryphonectria parasitica, VI is controlled by six vic loci and has been of particular interest because it impedes the spread of hypoviruses and thus biocontrol strategies. We use nuclear magnetic r ...

Abstract:
... The highly destructive chestnut blight disease can be successfully controlled by infecting the virulent strain of C. parasitica with the hyperparasitic mycovirus CHV-1. The artificial application of the virus-induced hypovirulence, however, requires that the vegetative compatibility (vc) diversity in the target C. parasitica population be determined beforehand. Conventional vc type determination b ...

Abstract:
... Xenorhabdus and Photorhabdus spp. are enteric bacterial symbionts of Steinernema and Heterorhabditis nematodes, respectively. These bacteria produce an extensive set of natural products (NPs) with antibacterial, antifungal, antiprotozoal, insecticidal, or other bioactivities when vectored into insect hemocoel by nematodes. We assessed the in vitro activity of different Xenorhabdus and Photorhabdus ...

Abstract:
... Since 1963 when chestnut blight was recorded for the first time in Greece, the disease has spread into all 29 chestnut growing prefectures. As a result the national, annual chestnut production was reduced from 18,000 tons in the 1960s to 11,000 tons in 2005. A project for the application of biological control on a nationwide scale was funded and implemented during the period 2007-2009. Hypovirulen ...

Abstract:
... Chestnut blight is controlled in Europe by using Cryphonectria hypovirus CHV1, a non-encapsulated RNA virus. The chestnut blight fungus, Cryphonectria parasitica, is weakened by the virus, and healing tissue growth occurs in the host tree. Transmission of this cytoplasmic hypovirus is restricted by the incompatibility system of the fungus, so that the hypovirus can be transmitted only between isol ...
