The petal blight disease of alpine Rhododendron severely impacts the ornamental and economic values Rhododendron. Plant secondary metabolites play a crucial role in resisting pathogenic fungi, yet research on petals that confer resistance to fungi is limited. In present study, delavayi, R. agastum, irroratum with anti-pathogenic activity were screened through index analysis, metabolomic detection, mycelial growth rate, metabolite spraying experiments. Disease analysis revealed delavayi exhibited strongest resistance, while agastum showed weakest, both under natural experimental conditions. UHPLC-QTOF-MS/MS identified 355 274 putative positive negative ion modes, respectively. further antifungal differentially accumulated baicalein, diosmetin, naringenin their half-inhibitory concentrations (IC50) against Neopestalotiopsis clavispora be 5000 mg/L, 1000 Spraying exogenous significantly alleviated caused by N. infection petals, inhibition rates exceeding 64%.

This paper discusses the mechanisms by which fungi manipulate plant physiology and suppress defense responses producing effectors that can target various host proteins. Effector-triggered immunity effector-triggered susceptibility are pivotal elements in complex molecular dialogue underlying plant-pathogen interactions. Pathogen-produced effector molecules possess ability to mimic pathogen-associated patterns or hinder binding of pattern recognition receptors. Effectors directly nucleotide-binding domain, leucine-rich repeat receptors, downstream signaling components defense. Interactions between these receptor-like kinases plants critical this process. Biotrophic adeptly exploit networks key hormones, including salicylic acid, jasmonic abscisic ethylene, establish a compatible interaction with their hosts. Overall, highlights importance understanding interplay fungal develop effective strategies for disease management.

Epigenetics has emerged as a potent field of study for understanding the factors influencing effectiveness human disease treatments and identifying alternations induced by pathogens in host plants. However, there been paucity research on epigenetic control proliferation pathogenicity fungal plant pathogens. Fungal such Magnaporthe oryzae , significant threat to global rice production, provide an important model exploring how mechanisms govern virulence. In M. alterations, DNA methylation, histone modification, non-coding RNAs, regulate gene expression patterns that influence pathogen’s ability infect its host. These modifications can enhance adaptability, allowing pathogen survive diverse environments evade immune responses. Our primary objective is comprehensive review existing shed light these changes lifecycle, invade tissues, overall severity disease.
