摘要

斑驳病是由胡椒黄斑驳病毒(PYMoV)引起的一种重要的辣椒病害。本研究旨在确定PYMoV的生物学和分子特性。辣椒植物样本取自Kleben、Putat(日惹)和Air Buluh(邦加)的胡椒农田。病毒颗粒是用电子显微镜测量的。病毒传播研究包括机械传播、媒介传播、扦插、嫁接和种子传播。以PYMoV-F和PYMoV-R特异性引物为引物,采用聚合酶链反应(PCR)方法进行分子检测。结果发现,病毒颗粒的形状为±30×130 nm。病毒传播研究表明,PYMoV可以通过Ferrisia virgata载体、插枝、嫁接和种子传播,但不能通过机械接种传播。分子检测结果显示,Kleben、Putat和Air Buluh辣椒样品均检测到PYMoV阳性,并在400 bp处扩增。核苷酸碱基序列分析结果显示,puat和Air Buluh分离株与印度2型PYMoV同源性最高,为95%,Kleben分离株与印度1型PYMoV同源性为96%。摘要/ abstract摘要/ abstract摘要/ abstract摘要/ abstractPenelitian ini bertujuan untuk mengetahui karakterisasi PYMoV secara生物学分子。Sampel tanaman lada diperoleh dari lahan petani lada di Desa Kleben, Putat(日惹),dan Air Buluh (Bangka)。粒子病毒diukur denkan microskop电子。卡吉安半岛病毒,媒介,猪,猪,猪,猪。用聚合酶链反应(PCR)制备了特异性PYMoV-F和PYMoV-R的登根pasangan引物。颗粒病毒杨德木肯·伯鲁库兰±30×130纳米伯鲁库克巴唐。卡吉安半岛病毒双歧双歧杆菌病媒虫,株,卡吉安半岛病毒双歧双歧杆菌病媒虫。Hasil uji分子menunjukkan bahwa样本tanaman lada Kleben, Putat dan Air Buluh阳性terdeksi PYMoV dan ter扩增kasi p400 bp。Hasil分析sekuen basa核核苷酸menunjukkan isolat puat dan Air Buluh memiliki homologi tertinggi dengan PYMoV India 2 sekitar 95% sedangkan isolat Kleben memiliki homologi 96% dengan PYMoV India 1。

Karakterisasi Virus Penyebab Penyakit Belang pada Tanaman Lada (Piper nigrum L.)
Mottle disease is an important disease in pepper plants caused by Piper yellow mottle virus (PYMoV). This study aims to determine the characterization of PYMoV biologically and molecularly. The pepper plant samples were obtained from pepper farmland in Kleben, Putat (Yogyakarta), and Air Buluh (Bangka). Virus particles are measured by electron microscopy. Virus transmission studies include mechanical transmission, vector, cuttings, grafting, and seeds. The molecular detection was done by using Polymerase chain reaction (PCR) method with PYMoV-F and PYMoV-R specific primers. The result, virus particles were found to be ± 30×130 nm in shape. Virus transmission studies indicate that PYMoV can be transmitted by Ferrisia virgata vectors, cuttings, grafts and seeds but cannot be transmitted through mechanical inoculation. Molecular test results showed that samples of Kleben, Putat and Air Buluh pepper plants were positively detected to contain PYMoV and amplified at 400 bp. The result of nucleotide base sequence analysis showed the isolates of Putat and Air Buluh had the highest homology with PYMoV of India 2 about 95% while Kleben isolate had 96% homology with PYMoV of India 1. IntisariPenyakit belang merupakan salah satu penyakit penting pada tanaman lada yang disebabkan oleh Piper yellow mottle virus (PYMoV).
