Abstract

Leaf yellowing symptoms was commonly found in cucumber plants in Bali provinces, i.e. in Apuan and Bangli villages recently. Begomovirus infection is suspected as the causal agent, due to similar symptoms previously reported from cucumber plants in Java. In addition, Bemisia tabaci was observed in the field. The objective of this research was to identify the causal agent of leaf yellowing disease of cucumber in Bali. Virus detection and identification was conducted by polymerase chain reaction method using universal primers for Begomovirus, i.e. SPG1/SPG2. DNA fragment of 912 bp in size was successfully amplified from leaf samples. Analysis of nucleotide sequencing indicated that Begomovirus infecting cucumber plants in Bali has the highest homology (91%) with Squash leaf curl China virus (SLCCNV) isolate from Malaysia. This is the first report of SLCCNV infection in Bali.

Abstract

Yellow disease on Cucurbitaceae caused by Squash leaf curl China virus (SLCCNV; Begomovirus) is an important disease in many countries. Typical yellow leaf curl symptoms was found on cucumber in Tabanan, Bali. The objective of this research is to clone Transcriptional Activator Protein (TrAp) and Replication-Associated Protein (Rep) of SLCCNV Indonesian isolate. Universal primer for Begomovirus, i.e. SPG1/SPG2 was used to amplify DNA fragment of Begomovirus which cover the TrAp and Rep gene. The amplicon of ± 912 bp in size was then cloned into pTZ57R/T plasmid vector by TA-cloning method to obtain plasmid recombinant pTZ-SLCCNV. The plasmid recombinant was successfully confirmed by PCR colony and DNA sequencing. The nucleotide sequences analysis of plasmid recombinant showed highest homology (98%) of the corresponding gene to pumpkin isolate of SLCCNV from Malaysia.
