Abstract:

Citrus fruits are one of the most important fruits in term of consumption as well as nutritional value. However, being such an important crop, it is infected by many diseases. One of the important diseases that can cause significant loss is citrus yellow mosaic virus disease. Citrus yellow mosaic virus causes severe mosaic disease in sweet oranges and has been reported earlier from India. In 2016, mosaic symptoms were observed in sweet oranges orchards in the Okara district at Punjab province of Pakistan. Leaf samples were collected from the 50 trees with symptoms. DNA was extracted by using sodium sulphite method. Conserved region of CYMV was amplified with PCR using primer pair (5GTGGCTTTCATCAGGTAGC, forward and 5CATGCATCCATCCGTTTCG, reverse). Approximately 640 bp Product was obtained. The PCR product was sequenced and BLASTn was performed and 96% similarity was found with the Indian isolate (GenBank accession no. AF347695). CYMV particles were propagated and transmitted to five healthy sweet orange trees through grafting. CYMV symptoms appeared after 65 days of grafting. After 80 days of transmission DNA was isolated from leaves and PCR for CYMV was conducted as described earlier. A Product of 638 bp was obtained. Thus, fulfilling Koch’s postulates. To our knowledge this is the first report of CYMV in citrus in Pakistan.
