Abstract

Cucumber mosaic virus on Black Pepper in Yogyakarta and Bangka BelitungPepper  (Piper  nigrum)  is  spice  crop  which  has  been  cultivated  a  long  time  ago  in  Indonesia. Stunting is one of disease on pepper caused by cucumber mosaic virus (CMV). The research aimed to diagnose the biological, morphological and nucleaic acid characters of CMV on pepper in Yogyakarta and Bangka Belitung. CMV infection on pepper in both area (Putat dan Kleben village, Yogyakarta and Air Buluh village, Bangka Belitung) showed typical symptoms such as mosaic, narrow leaves and stunting. The disease incidence and disease severity of stunting disease are varies. The virus able to transmitted by cutting, grafting and mechanically on Nicotiana tabacum and Chenopodium amaranticolor. However, it was unable to transmitted mechanically on pepper and by Aphis gossypii. The virus particles were isometric with diameter size 28-30 nm. RT-PCR using coat protein partial gene primer successfully amplified a DNA with size ± 500 bp from all three samples. The homology of nucleotide between three isolates was 98-97%, while the highest homology of those three strains CMV  from Yogyakarta and Bangka Belitung was 98% against strains from China in Brassica chinensis. Three strains CMV from pepper were in the same group, and separated from CMV pepper lines from Indonesia and other CMV isolates.

Abstract

Gejala mosaik kuning dan keriting daun ditemukan pada pertanaman kacang panjang di Sleman, Yogyakarta. Begomovirus diketahui sebagai salah satu penyebab penyakit tersebut. Penelitian dilakukan untuk mengidentifikasi spesies Begomovirus dan DNA satelit yang berasosiasi dengan penyakit mosaik kuning kacang panjang. Ekstraksi DNA total dari tanaman bergejala dilanjutkan dengan amplifikasi fragmen DNA spesifik Begomovirus dan Betasatelit. Amplikon DNA berukuran ±1500 pb dan ±1300 pb berhasil diperoleh menggunakan berturut-turut primer universal Begomovirus dan primer spesifik Betasatelit. Analisis sekuen nukleotida mengonfirmasi identitas Begomovirus yang menginfeksi tanaman kacang panjang ialah Mungbean yellow mosaic India virus (MYMIV) dengan homologi 99% terhadap isolat MYMIV asal Indonesia. DNA satelit yang berasosiasi dengan MYMIV menunjukkan karakteristik Betasatelit, yaitu memiliki satellite common region (SCR) dengan struktur stem-loop dan sekuen TAATATTAC pada bagian loop, adenine rich region sebesar 54.96%, dan ORF (open reading frame) non-coding. Lebih lanjut, analisis rekombinasi menggunakan SimPlot mengindikasikan bahwa satelit non-coding MYMIV merupakan satelit rekombinan antara Betasatelit dan DNA-B Pepper yellow leaf curl Indonesia virus (PepYLCIV). Artikel ini merupakan laporan pertama asosiasi betasatelit DNA non-coding dengan MYMIV di Indonesia.

Abstract

There are several ways to eliminate virus, suach as the application of thermoterapi and chemotherapy technique, and also the apex and meristem culture. One way to control this disease is the use of virus-free seedlings. The objective of this study was to find out the effect of combined treatment between thermotherapy or chemotherapy with apex or meristem culture to mosaic virus elimination of sugarcane. There were four steps in this research: (1) Virus detection of mother plant, (2) Application of thermotherapy at 50oC and chemotherapy by using Ribavirin 25 µg/l combined with apex culture, (3) Application of thermotherapy and chemotherapy combined with meristem culture, and (4) Evaluation of virus elimination. The plant materials used were PS862 from Cirebon (PS862-Crb), PS881 from Surabaya (PS881-Sby) and PSJK922 (PSJK922-Bgr) from Bogor. Virus detection was conducted by TEM and RT-PCR analysis. The temperature for thermotherapy was 500C and the antiviral agent was Ribavirin (0 and 25 μg/l). The result showed that thermotherapy or chemotherapy combined with apex culture could not eliminate virus infection. The combined treatment of chemotherapy and meristem culture could eliminate SCSMV in variety PS862-Crb based on RT-PCR assay, however TEM analysis still detected the viral particle. It was suggessted to udertake virus indexing of large number of samples to see the rate of virus elimination.Keywords: Saccharum officinarum L., Ribavirin, Potyvirus, TEM, RT- PCR

Abstract

Yellow curl disease caused by begomovirus is a major threat for horticulture in Indonesia. Control mea‐ sures for the disease face several constraints, one of which is the association between begomovirus and DNA satellites which can affect the severity of symptoms. In this study, we detected the presence of a DNA satellite associated with begomovirus in a highland area. The sample was obtained from Ketep, Magelang, located approximately 1400 meters above sea level. Begomovirus was detected using primers PAL1V1978/PAR1C715 that resulted in an amplicon of ap‐ proximately 1600bp. The presence of this satellite was detected using primers CLB36F/CLB37R, resulting in full‐length satellite genome of approximately 1300bp. Sequence analysis showed the sample was infected by Pepper yellow leaf curl Indonesia virus (PepYLCIV) and a non‐coding satellite which resembled some characteristics of common betasatellites with imperfect putative ORF βC1. SimPlot analysis revealed the recombination event between betasatellites and DNA‐B of PepYLCIV. The satellite found in this study is thought to be the result of recombination due to multiple infections in plants.

Abstract

Soft rot is one of the most important diseases of orchids caused by Pectobacterium carotovorum. The conventional methods for the detection of pathogen is tedious and time consuming. In recent years, numerous molecular diagnostic approaches for the detection of P. carotovorum have been developed, including various PCR-based assays. Optimization of PCR technique to DNA amplification is essential for time and material efficiency, which will make detection to be rapid and more appropriate. The purposes of this study were to decide concentration of DNA and primer, and also the concentration of bacterial pure cultures and primer to amplify 16S rRNA gene fragment. Optimization of PCR was done by using various concentration of DNA, pure cultures of bacteria, and primer to amplify the 16S rRNA gene sequence. The results showed that the most optimum concentration to amplify 16S rRNA gene sequence at DNA and primer concentration were 63,4 ng/µl and 10 pmol, while pure cultures and primer concentrations were at 8×109 CF U/ml and 10 pmol respectively. Penyakit busuk lunak yang disebabkan oleh Pectobacterium carotovorum merupakan salah satu penyakit penting pada tanaman anggrek. Deteksi patogen secara cepat dan akurat dapat dilakukan secara molekular menggunakan teknik Polymerase chain reaction (PCR). Optimasi metode PCR perlu dilakukan untuk mengefisienkan waktu dan penggunaan bahan sehingga proses deteksi dapat dilakukan dengan cepat dan tepat. Penelitian ini bertujuan untuk menentukan konsentrasi DNA dengan primer maupun konsentrasi kultur murni bakteri dengan primer yang paling tepat untuk mendapatkan fragmen gen 16S rRNA. Optimasi PCR dilakukan menggunakan beberapa variasi pengenceran pada DNA, kultur murni bakteri, dan primer untuk mengamplifikasi gen 16S rRNA. Hasil penelitian menunjukkan bahwa konsentrasi yang paling optimal untuk mengamplifikasi gen 16S rRNA yaitu DNA dan primer masing-masing sebesar 63,4 ng/µl dan 10 pmol, sedangkan konsentrasi kultur murni dan primer sebesar 8×109 CFU/ml dan 10 pmol.

Abstract

Susceptibility of the armyworm, Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae) to nucleopolyhedrovirus was evaluated using droplet feeding methods. S. litura was originally collected from the field in Bantul and has been reared continuously in the laboratory using artificial diet. The tested instars were exposed a series concentration of nucleopolyhedrovirus (2×103, 2×104, 2×105, 2×106, 2×107, 2×108, 2×109 PIB/ml) which were added with Tinopal 0,5% and 1%. The result indicated that the larval mortality of 3rd, 4th, and 5th instars Tinopal, significantly different with the addition of 1% Tinopal. This addition increased the effectiveness of NPV for 235, 25117, and 6.6 million fold. The observation of the larval midgut which was treated by Tinopal, showed that Tinopal physically disrupt the peritrophic membrane. Therefore, it can be suggested that the Tinopal facilitates the entry of NPV to the host insect.

Abstract

Banana bunchy top disease (BBTD) can be caused by the infection of two different viruses, Banana bunchy top virus (BBTV) or Abaca bunchy top virus (ABTV). Both viruses can be transmitted persistently by aphid Pentalonia nigronervosa Coq. The research was conducted to detect and to differentiate the virus bypolymerase chain reaction-restriction fragment length polymorphism (PCRRFLP) techniques. Infected plants were collected from Yogyakarta (Sleman, Yogyakarta city, Bantul, Gunung Kidul, and KulonProgo). Nucleon Phytopure DNA Extraction Kit method was used to extract the total DNA of infected plants. Universal primers of Common DNA region (S-CRF and S-CRR) and specific primers DNA-R (C1-CRF and CI-CRR) were used for PCR amplification. PCR products were analyzed by RFLP technique using the restriction enzyme of DraI. The results reconfirm previous reports that bunchy top disease of banana in Yogyakarta is caused by BBTV. The ABTV was not detected in this present study. Based on the RFLP analysis it was concluded that BBTV collected in this study could be divided into three groups. Group 1 consisted of BBTV isolate from Sleman and Yogyakarta city with two fragments DNA of 400 and 388 bp. Group 2 consisted of isolate BBTV from Kulon Progo and Gunung Kidul with three fragments DNA of 400, 388, and 323 bp. Group 3 consisted of isolate from Bantul with two fragments DNA of 723 and 376 bp. Further study on the complete characteristics of these groups is still needed.
