The receptor-like kinase (RLK) family of receptors and the associated receptor-like cytoplasmic kinases (RLCKs) have expanded in plants because of selective pressure from environmental stress and evolving pathogens. RLCKs link pathogen perception to activation of coping mechanisms. RLK-RLCK modules regulate hormone synthesis and responses, reactive oxygen species (ROS) production, Ca signaling, activation of mitogen-activated protein kinase (MAPK), and immune gene expression, all of which contribute to immunity.

Article Synopsis
  • Sorghum anthracnose, caused by the fungus Colletotrichum sublineola, is a significant disease affecting sorghum crops, and the study identifies two dominant resistance genes, ARG4 and ARG5, linked to this disease.
  • Both genes encode for NLR receptors and were found in sorghum lines SAP135 and P9830, exhibiting broad-spectrum resistance to various strains of the fungus.
  • Genetic mapping and comparative genomics reveal that ARG4 and ARG5 are within clusters of duplicate NLR genes, suggesting a complex genetic relationship with potential implications for future breeding and resistance studies.

Pathogenesis in plant diseases is complex comprising diverse pathogen virulence and plant immune mechanisms. These pathogens cause damaging plant diseases by deploying specialized and generic virulence strategies that are countered by intricate resistance mechanisms. The significant challenges that necrotrophs pose to crop production are predicted to increase with climate change.

The study assessed dairy cattle management practices and identified constraints at smallholder dairy farms in Dilla-Zuriya District. A cross-sectional survey was undertaken on 120 purposely selected smallholder dairy farmers from three potential kebeles (Chichu, Andida and Gola). A Structured questionnaire was developed and applied to collect data.
