Genetic control of Eucalyptus urophylla and E. grandis resistance to canker caused by Chrysoporthe cubensis
Chrysophorte cubensis induced canker occurs in nearly all tropical and subtropical regions where eucalypts are planted, causing losses in both wood quality and volume productivity, especially so in the warmer and more humid regions of Brazil. The wide inter and intra-specific genetic variability of resistance to canker among Eucalyptus species facilitates the selection of resistant plants. In t...
متن کاملCharacterization of South African Cryphonectria cubensis Isolates Infected with a C. parasitica Hypovirus.
ABSTRACT Cryphonectria cubensis is the causal agent of a serious canker disease of Eucalyptus spp. in tropical and subtropical parts of the world. In this study, a South African C. cubensis isolate was transfected by electroporation with a synthetic RNA transcript corresponding to the full-length coding strand of the C. parasitica hypovirus (CHV1-EP713). Hypovirus infection resulted in pronounc...
متن کاملSeed Transmission of Pseudoperonospora cubensis
Pseudoperonospora cubensis, an obligate biotrophic oomycete causing devastating foliar disease in species of the Cucurbitaceae family, was never reported in seeds or transmitted by seeds. We now show that P. cubensis occurs in fruits and seeds of downy mildew-infected plants but not in fruits or seeds of healthy plants. About 6.7% of the fruits collected during 2012-2014 have developed downy mi...
متن کاملNovel hosts of the Eucalyptus canker pathogen Chrysoporthe cubensis and a new Chrysoporthe species from Colombia.
The pathogen Chrysoporthe cubensis (formerly Cryphonectria cubensis) is best known for the important canker disease that it causes on Eucalyptus species. This fungus is also a pathogen of Syzygium aromaticum (clove), which is native to Indonesia, and like Eucalyptus, is a member of Myrtaceae. Furthermore, C. cubensis has been found on Miconia spp. native to South America and residing in Melasto...
متن کاملBiotransformation of Tryptamine in Fruiting Mycelia of Psilocybe cubensis.
Mycelial cultures of PSILOCYBE CUBENSIS, with the ability to form psilocybin and psilocin DE-NOVO, also hydroxylated and methylated fed tryptamine to give psilocin in up to 3.3% dry mass of the obtained fruit bodies. By using HPLC and TLC, it was found that these mushrooms contain only a small amount of psilocybin (0.01-0.2% dry mass). The values of psilocin are the highest described in any mus...
