Abstract

Severe mosaic symptoms was observed on papaya plants in Meusa village, Kutablang sub district, Bireun district and Lambaro Teunom village, Lembah Seulawah sub district, Aceh Besar district. Systemic mosaic was found in leaves, stem, twig, and fruit. Reverse transcription-polymerase chain reaction (RT-PCR) was conducted to detect the virus causing mosaic symptoms using universal primer for Potyvirus. Amplification of 320 bp DNA fragment was successfully obtained from leaves and fruits bearing severe mosaic symptoms. Nucleotide sequencing was proceeded using the DNA amplicon as the template. Further sequence analysis indicated that Potyvirus isolates from papaya in Aceh show the highest homology (92.7% to 94.7%) with Papaya ringspot virus (PRSV) from Philippines, Thailand, and Indonesia. This is the first report on PRSV infection on papaya in Nanggroe Aceh Darussalam province.   Key words: Potyvirus, RT-PCR, sequencing

Abstract

Tomato chlorosis disease was found more frequent on production area in West Java recently. Observation in the field showed typical symptoms of Tomato infectious chlorosis virus (TICV) and Tomato chlorosis virus (ToCV). The objective of this research is to identify TICV and ToCV associated with chlorosis disease on tomato plants in West Java (Cipanas, Lembang and Garut) using reverse transcription polymerase chain reaction (RT-PCR) method and nucleotide sequence analysis. DNA target of 417 bp and 360 bp was successfully amplified only from Cipanas sample using specific primers, TICV-CF/TICV-CR and ToCV-CF/ToCV-CR, respectively. Sequence analysis confirmed that chlorosis disease in Cipanas was associated with TICV and ToCV infection. Nucleotide sequence and phylogenetic analysis showed that TICV from Cipanas has high homology to and belongs to the same group with TICV from Japan and Spain; whereas ToCV from Cipanas has high homology to and belongs to the same group with ToCV from America.

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.

Abstract

Begomovirus was identified as one of the causal agents causing yellow mosaic disease on yard long bean (Vigna unguiculata subsp. sesquipedalis L.) in Java. Research was conducted to characterize the virus based on its nucleotide sequences.  Research was started by field survey to collect leaf samples, followed by virus detection using polymerase chain reaction and analysis of virus sequences.  Samples from Tegal, Klaten, Magelang, Cirebon, Subang, and Bogor were positively infected by Begomovirus based on specific viral DNA amplification.  Sequence analysis indicated that Begomovirus infecting yard long bean belongs to the same group with Mungbean yellow mosaic India virus (MYMIV) from Bangladesh, India, Pakistan, and Nepal.  Further analysis showed the conserved region of Begomovirus around Common Region, i.e. “TATA box” Sequence, Hair Pin Loop Structure, Repetitive Sequence, and the Conserved Nonanucleotide Sequence TAATATTAC.Key words: common region, DNA sequencing, ELISA, MYMIV, PCR
