ABSTRACT Black pod disease, caused by a complex of Phytophthora species, poses a severe threat to global cacao production. This study explores the use of CRISPR–Cas9 genome editing to reduce disease susceptibility in Theobroma cacao L. by targeting the TcNPR3 gene, a known negative regulator of plant defence.

Alfalfa (Medicago sativa) seeds planted in cold, wet soil are prone to seed rot, pre- and postemergence damping-off, and seedling root rot. These diseases reduce initial stand density and affect forage yields and winter survival when root systems are ...

ABSTRACT Oomycete pathogens secrete hundreds of RXLR effectors into plant cells to modulate host immunity by targeting diverse plant proteins. Here, we report that the Peronophythora litchii RXLR effector PlAvh133 acts as a virulence factor and targets the litchi glycolate oxidase (GLO) LcGLO1, a key enzyme in photorespiration, thereby suppressing ...

Populations of Phytophthora sojae are diverse within single fields [PDF]
Phytophthora root and stem rot of soybean (PRR), caused by Phytophthora sojae, is well known to Iowa growers. The disease occurs throughout the growing season when soil temperatures are above 70 °F and especially following episodes of heavy rain.

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