CP32, a novel anti‐oomycete cyclic peptide, interferes with cell‐wall deposition in Phytophthora infestans

Journal of Integrative Plant Biology, EarlyView.
The small cyclic peptide CP32 effectively inhibits Phytophthora infestans, the causal agent of potato and tomato late blight. Combined biochemical and phenotypic analyses demonstrate that CP32 disrupts cell wall biosynthesis, a key process in pathogen infection, resulting in a marked reduction of disease symptoms in plants.

Distinct small RNAs are expressed at different stages of Phytophthora capsici and play important roles in development and pathogenesis

Frontiers in Genetics
Small RNAs (sRNAs) are important non-coding RNA regulators that play key roles in the development and pathogenesis of plant pathogens, as well as in other biological processes.

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 ...

Overwintering seeds as reservoirs for seedling pathogens of wetland plant species

Ecosphere, 2016
Seed germination and seedling establishment are central to the distribution and abundance of plant species in wetlands. While fungal and oomycete pathogens are known to affect seed viability and emergence, relatively little is known about which fungi and

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.

Insights Into the Role of Lysine Acetylation of Non‐Histone Proteins in Plant Immunity

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant immunity is regulated by numerous transcriptional and posttranslational mechanisms. Among these, lysine acetylation, which is controlled by lysine acetyltransferases (KATs) and lysine deacetylases (KDACs), has been extensively studied, particularly in the context of epigenetic regulation through histone acetylation.

Effects of Atmospheric CO2 Levels on the Susceptibility of Maize to Diverse Pathogens

Plant, Cell &Environment, EarlyView.
ABSTRACT Rising atmospheric CO2 has significant implications for crop productivity and food security. Based on studies in C3 plants, elevated CO2 (eCO2) can shape plant‐pathogen interactions, although the outcomes are often variable. The question of how eCO2 influences immunity and disease development in C4 plants, such as the globally important cereal

Effector Repertoire of Phytophthora betacei: In Search of Possible Virulence Factors Responsible for Its Host Specificity

Frontiers in Genetics, 2020
Phytophthora betacei is an oomycete plant pathogen closely related to Phytophthora infestans. It infects tree tomato (Solanum betaceum) in northern South America, but is, under natural conditions, unable to infect potatoes or tomatoes, the main hosts of ...

Harnessing benzamides as plant stress inhibitors, growth promoters and in management of crop resilience—A review

Plant Biology, EarlyView.
Benzamides boost crop resilience by inhibiting poly(ADP‐ribose) polymerase (PARP) to enhance stress tolerance and, through their antimicrobial, herbicidal, and insecticidal derivatives, they offer broad protection for sustainable crop improvement. Abstract Benzamides have emerged as potent stress inhibitors and growth promoters in plant biotechnology ...
