The class III peroxidase (POD) gene family encodes redox enzymes involved in the catalytic processes of hydrogen peroxide, phenolic compounds, and reactive oxygen species. These play crucial roles lignin biosynthesis stress responses. To explore functions oat (Avena sativa) POD (AsPOD) resistance to powdery mildew, we performed a genome-wide analysis bioinformatics characterization. A total 97 AsPOD genes were identified, unevenly distributed across 21 chromosomes. Structural predictions indicated that α-helices are predominant structural components proteins, phylogenetic revealed six clades with high homology proteins Poaceae family. Cis-regulatory element three associated hormone signaling, light response, resistance. Analysis duplication events indicates there 55 pairs segment duplications among 69 genes. Expression profiling mildew-infected varieties showed significant up- or downregulation several (AsPOD51, AsPOD55, AsPOD63, AsPOD89), identifying them as key candidates for disease studies. Furthermore, resistant exhibited higher content than susceptible ones. Correlation AsPOD51, AsPOD88, AsPOD89 stronger positive association varieties. After inoculation mildew pathogen, H2O2 rapidly increases, activity first rises then decreases. Those findings provide foundation further research into role

Transmembrane proteins (TMPs) are pivotal components of plant defence mechanisms, serving as essential mediators in the response to biotic stresses. These among most complex and diverse within cells, making their study challenging. In spite this, relatively few studies have focused on investigation characterization TMPs plants. This is particularly true for grapevine. review aims provide a comprehensive overview TMP-encoding genes involved grapevine immunity. include Lysin Motif Receptor-Like Kinases (LysM-RLKs), which recognition pathogens at apoplastic level, Plant Respiratory Burst Oxidase Homologs (Rbohs), generate reactive oxygen species (ROS) host defense, Sugars Will Eventually be Exported Transporters (SWEETs), play role nutrient allocation stress responses. Furthermore, discusses methodologies employed TMPs, including
