Genomic signatures of heterokaryosis in the oomycete pathogen Bremia lactucae. [PDF]

, 2019
Lettuce downy mildew caused by Bremia lactucae is the most important disease of lettuce globally. This oomycete is highly variable and rapidly overcomes resistance genes and fungicides.

Alien Species in Finnish Nurseries, Phytophthora spp.

Acta Silvatica et Lignaria Hungarica, 2007
International trade has increased the risk of pest spread. The climatic change will also improve the establishment of introduced species into new geographical areas. Since the beginning of 1990's Phytophthora cactorum has caused losses in agriculture on strawberries and caused stem lesions on silver birch seedlings in forest nurseries in Finland.

Protection of Citrus Rootstocks Against Phytophthora spp. with a Hypovirulent Isolate of Phytophthora nicotianae [PDF]

Phytopathology®, 2007
Phytophthora root rot of citrus in Florida is caused by Phytophthora nicotianae and P. palmivora. A naturally occurring isolate of P. nicotianae (Pn117) was characterized as hypovirulent on citrus roots. Pn117 infected and colonized fibrous roots, but caused significantly less disease than the virulent isolates P. nicotianae Pn198 and P.

Phage Display Derived Antibodies Against Antimicrobial Peptide FsPDF2 Reveal Stress Response in European Beech

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant defensins (PDFs) are cysteine‐rich antimicrobial peptides (AMPs) that are important components of plant immunity. They occur constitutively in various plant tissues but are also upregulated upon stress. Therefore, these molecules are of great interest as markers for the diagnosis of early forest stress response in plants at the molecular

Evaluation of Allyl Isothiocyanate and Ethylicin as Potential Substrate and Space Fumigants in Tomato Greenhouses

Agriculture
Continuous use of substrate cultivation can easily lead to the accumulation of crop pathogens, leading to widespread crop diseases. It is necessary to screen suitable and efficient substrate and space fumigants to keep the healthy development in ...

New insights into the supression of plant pathogenic fungus (Phytophthora cinnamomi) by compost leachates [PDF]

, 2003
Use of compost as a soil conditioner and low-grade fertiliser is gaining popularity worldwide (Epstein, 1997). Compost not only adds plant nutrients to the soil, but also improves physical properties of soil such as buffering capacity, cation exchange ...

Strategies for administration of biosurfactants-producing pseudomonads in closed hydroponic systems [PDF]

, 2011
Zoospore-producing oomycetes are major plant pathogens of particular concern in hydroponic systems. Compared with pesticides, biocontrol using antagonistic microorganisms is a sustainable approach to control oomycetes.

WRKY Transcription Factors: Integral Regulators of Defence Responses to Biotic Stress in Crops

Plant Biotechnology Journal, EarlyView.
ABSTRACT Crops are continually challenged by biotic stresses, including fungal, bacterial and viral pathogens and insect pests, which cause substantial yield and quality losses worldwide. WRKY transcription factors constitute a plant‐specific and functionally diverse family that is central to immune regulation.

Cladobotryum mycophilum as Potential Biocontrol Agent [PDF]

, 2019
A study was conducted to explore the efficacy of potential biocontrol agent Cladobotryum mycophilum against different phytopathogenic fungi. The growth rates of 24 isolates of C. mycophilum were determined, and their antagonistic activity was analysed in

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.
