The coat protein gene and its 3′ noncoding region of a watermelon isolate of Cucumber green mottle mosaic virus (CGMMV-LN) in Liaoning, China was determined and compared with other isolates. The gene encoding the coat protein of CGMMV-LN comprises of 486 nucleotides and encodes a putative protein of 161 amino acids. Sequence comparisons showed that the coat protein of this isolate was identical to that of seven CGMMV isolates infecting cucurbits in Europe and Asia. The 3′ noncoding region of CGMMV-LN consists of 176 nucleotides, which is same as that of CGMMV-KOM, CGMMV-KW and CGMMV–SH.
