Abstract

When 66 cucurbit samples with yellowing symptoms from fields in Mali, the Philippines, Thailand and Uzbekistan were screened by RT-PCR using universal polerovirus primers, 21 were identified as harboring polerovirus RNA. When these 21 samples were screened with specific primers for the known cucurbit-infecting poleroviruses, suakwa aphid-borne yellows virus and a recombinant strain of cucurbit aphid-borne yellows virus were detected for the first time in the Philippines and Thailand. However, seven polerovirus-positive samples did not react with any of the known species-specific primers. Sequencing of 1.4-kb universal polerovirus RT-PCR products revealed the presence of two poleroviruses that had not been described previously. These viruses, from Mali and Thailand, were provisionally named pepo aphid-borne yellows virus and luffa aphid-borne yellows virus, respectively.
