Drying out of woody plants at Peter the Great Botanical Garden BIN RAS (Saint Petersburg) and distribution of Phytophthora and Pythiumspecies: monitoring of 2018

Hortus Botanicus, 2019
During the study period of 2011-2018, six species of phytophthoras and one species of pythium were identified at the dendrarium park of the Peter the Great Botanical Garden of the Komarov Botanical Institute RAS. During two vegetative seasons of 2017 and

Comparative analysis of Phytophthora genomes reveals oomycete pathogenesis in crops

Heliyon, 2021
The oomycete genus Phytophthora includes devastating plant pathogens that are found in almost all ecosystems. We sequenced the genomes of two quarantined Phytophthora species–P. fragariae and P. rubi.

Styrene and its natural analogues: accumulation and sustainable production methods

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Styrene, also known as vinyl benzene, is a colourless, highly volatile petrochemical that serves as a key monomer in the production of polystyrene and styrene‐butadiene rubber. Its industrial synthesis via the alkylation of benzene with ethylene relies on fossil fuels, requiring high temperatures and toxic catalysts that contribute to ...

False-negative isolations or absence of lesions may cause mis-diagnosis of diseased plants infected with Phytophthora cinnamomi [PDF]

, 2000
In a series of growth cabinet, glasshouse and field experiments, tissue samples from living clonal Eucalyptus marginata (jarrah) were incubated immediately after sampling on agar (NARPH) selective for Phytophthora.

Fine mapping of cucumber downy mildew resistance loci identifies candidate genes linked to ethylene‐associated stomatal defence

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Downy mildew, caused by Pseudoperonospora cubensis, is one of the most destructive diseases affecting cucumber and remains difficult to manage sustainably through fungicide‐dependent control strategies. Although several resistance loci have been reported, many previously mapped regions remain too broad for efficient marker‐assisted ...

The lectin receptor kinase LecRK-I.9 is a novel Phytophthora resistance component and a potential host target for a RXLR effector [PDF]

, 2011
In plants, an active defense against biotrophic pathogens is dependent on a functional continuum between the cell wall (CW) and the plasma membrane (PM). It is thus anticipated that proteins maintaining this continuum also function in defense. The legume-

The epigenetic landscape of plant defense: Unlocking nature's toolkit for new plant protection

New Plant Protection, EarlyView.
This review examines how epigenetic mechanisms regulate plant immune gene activation, repression, and priming, then links these natural regulatory layers to emerging epigenetic editing, discussing their potential for precise, heritable crop protection and the challenges.

DNA methods for the detection of Phytophthora cinnamomi from soil [PDF]

, 2006
This project assesses two aspects of DNA detection of Phytophthora species from soil samples. Firstly, a nested PCR protocol was established with both primary and nested PCR specific for P. cinnamomi detection. PCR amplification of P.
