| Yellow leaf syndrome (YLS) of sugar cane is characterized by the yellowing of the midrib followed by the leaf blades in mature canes. Two pathogens have been associated with the disease; a luteovirus, Sugar cane yellow leaf virus (SCYLV) and a phytoplasma, sugar cane yellows phytoplasma (SCYP). Reverse transcriptase polymerase chain reaction (RT-PCR) was used to identify the virus while a nested-PCR was found to be reliable for the detection of the phytoplasma. The two pathogens were observed in sugar cane plants with or without symptoms and they also co-existed in a number of varieties. A strong correlation was found between the presence of the phytoplasma and YLS symptoms when compared to the presence of the virus. Restriction fragment length polymorphism (RFLP) analysis of the phytoplasma 16S rRNA amplified product demonstrated the presence of at least three phytoplasma groups in sugar cane in Mauritius. | |
