Article Synopsis
- The study investigates how orange rust, caused by the fungus Puccinia kuehnii, affects the immune responses in sugarcane plants, which leads to crop yield reduction after infection.
- Using RNA-Seq, the research analyzes gene expression at various time points post-inoculation, revealing initial suppression of plant defense-related genes and later partial recovery of immune responses.
- Findings suggest that the pathogen may initially hinder sugarcane's defense mechanisms, leading to inefficient recognition and response in susceptible varieties of the plant.
The sustainability of global crop production is critically dependent on improving tolerance of crop plants to various types of environmental stress. Thus, identification of genes that confer stress tolerance in crops has become a top priority especially in view of expected changes in global climatic patterns. Drought stress is one of the abiotic stresses that can result in dramatic loss of crop productivity.
