Colonization of the xylem of sugarcane by subsp. results in the occlusion of the vessels by a gum-like compound and compromises the elongation of the stalk leading to stunted plants. However, no study has been performed in the apical tissue where the elongation of the stalks initiates at the intercalary meristem (IM).

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.
Despite of the importance of ratoon stunting disease, little is known on the responses of sugarcane to its causal agent, the vascular bacterial endophyte Leifsonia xyli subsp. xyli. The transcriptome and proteome of young plants of a susceptible cultivar with no symptoms of stunting but with relative low and high bacterial titers were compared at 30 and 60 days after inoculation.
