Marine Oomycetes of the Genus Halophytophthora Harbor Viruses Related to Bunyaviruses

Frontiers in Microbiology, 2020
We investigated the incidence of RNA viruses in a collection of Halophytophthora spp. from estuarine ecosystems in southern Portugal. The first approach to detect the presence of viruses was based on the occurrence of dsRNA, typically considered as a ...

New insights into the novel and functional promoter sequences of β-1,3-glucanase gene from Hevea brasiliensis

Journal of Plant Protection Research, 2021
β-1,3-glucanases play a major role in combating the abnormal leaf fall disease (ALF) caused by the oomycete Phytophthora spp. in Hevea brasiliensis, the major commercial source of natural rubber. In this study, partial sequences of four novel promoters

Metabolomic and Physiological Changes in Fagus sylvatica Seedlings Infected with Phytophthora plurivora and the A1 and A2 Mating Types of P. ×cambivora

Journal of Fungi, 2022
Phytophthora infections are followed by histological alterations, physiological and metabolomic adjustments in the host but very few studies contemplate these changes simultaneously.
