AIIMS 2018 Botany Bacterial Diseases MCQ Question

Citrus canker is caused by the bacterium Xanthomonas citri, which infects citrus plants, leading to the characteristic lesions on leaves, stems, and fruit. This bacterial infection is distinct from viral and fungal diseases, which are caused by different pathogens; viruses typically require a host cell to replicate, while fungi can cause decay and rot but do not produce the specific symptoms seen in citrus canker. Understanding the causative agent of citrus canker is crucial for implementing effective management strategies in agriculture.
