Microorganisms from corn stigma with biocontrol potential of Fusarium verticillioides

Brazilian Journal of Biology, 2022
The mycotoxigenic fungus Fusarium verticillioides is the primary maize pathogen and causes the maize stalk and ear rot diseases with significant economic losses. Furthermore, the excessive use of fungicides to control F.

Systemic acquired resistance: an emerging role for jasmonates in local signal biogenesis, translocation and distal signal decoding

New Phytologist, EarlyView.
Jasmonate signalling underpins establishment of plant systemic acquired resistance (SAR). Activation of the hypersensitive response (HR) not only contains the pathogen but establishes broad spectrum resistance in unchallenged leaves. The strong burst of reactive oxygen/nitrogen species initiating the HR results in lipid peroxidation (illustrated by ...

Carbon catabolite repression in pectin digestion by the phytopathogen Dickeya dadantii [PDF]

, 2022
International audienceThe catabolism of pectin from plant cell walls plays a crucial role in the virulence of the phytopathogen Dickeya dadantii. In particular, the timely expression of pel genes encoding major pectate lyases is essential to circumvent ...

Characterization of Growth Morphology and Pathology, and Draft Genome Sequencing of Botrytis fabae, the Causal Organism of Chocolate Spot of Faba Bean (Vicia faba L.)

Frontiers in Microbiology, 2020
Chocolate spot is a major fungal disease of faba bean caused by the ascomycete fungus, Botrytis fabae. B. fabae is also implicated in botrytis gray mold disease in lentils, along with B. cinerea. Here we have isolated and characterized two B.

Unfolding Plant Defence: Endoplasmic Reticulum Stress Signalling at the Plant‐Pathogen Interface

Plant Biotechnology Journal, EarlyView.
ABSTRACT The endoplasmic reticulum (ER) stress response, a conserved proteostasis network, has emerged as a central hub that reprograms plant immunity during pathogen attack. This review synthesises how plants harness ER‐stress signalling to mount multilayered defences and how pathogens have evolved counterstrategies to subvert these pathways.

Metabolic shift in the phytopathogen Rhodococcus fascians in response to cell-free extract of infected tobacco plant tissues. [PDF]

, 2009
The phytopathogen Rhodococcus fascians induces the development of leafy gall, which is considered to be its ecological niche. To obtain a view of the metabolic changes occurring in R.

Interactional Endocytosis and Transmembrane Transport Promote Cellular Internalization of Nano‐Delivered RNA Drugs for Efficient Control of Crop Diseases

Plant Biotechnology Journal, EarlyView.
ABSTRACT Botrytis cinerea is a widespread plant pathogenic ascomycete that causes grey mould in over 1400 species and impacts global crop yields. Double‐stranded RNA (dsRNA)‐induced gene silencing is a promising technology for pest control, but efficient delivery remains a major challenge.

An indole dimer antifungal metabolite from a rice seed endophyte inhibits ergosterol biosynthesis in fungal pathogens

Applied and Environmental Microbiology
The increasing prevalence of fungal phytopathogens and the widespread emergence of fungicide resistance necessitate the development of alternative antifungal strategies with reduced environmental impact. Here, we report the isolation and characterization

The Putative Effector Protein AlPE1 From Ascochyta lentis Causes Necrosis in Lentil and Pea

Legume Science, Volume 8, Issue 3, September 2026.
ABSTRACT Ascochyta blight of lentil is caused by the hemibiotrophic fungal pathogen species Ascochyta lentis. Recent advances in whole genome sequencing have led to the availability of many fungal genome assemblies, enabling comparison of isolates that can lead to the identification of virulence genes or effectors.

Inhibitory effect of chitosan on growth of the fungal phytopathogen, Sclerotinia sclerotiorum, and sclerotinia rot of carrot [PDF]

, 2015
The antifungal activity of chitosan on a common fungal phytopathogen, Sclerotinia sclerotiorum, and the control effect on sclerotinia rot of carrot were investigated. Mycelial growth and fungal biomass were strongly inhibited by chitosan. Using propidium
