Virus infection in chili plants may cause various symptoms. The complexity of the symptoms and human vision ability often become limiting factors during disease investigations. Digital image analysis is expected to a method assist comprehensively describing plant viruses. A survey was conducted on cayenne pepper fields Southeast Sulawesi Province observe virus virtually record symptomatic using...

The RNA replicase extracted from Brome mosaic virus (BMV)-infected plants has been used to characterize the cis-acting elements for RNA synthesis and the mechanism of RNA synthesis. Minus-strand RNA synthesis in vitro requires a structure named stem-loop C (SLC) that contains a clamped adenine motif. In vitro, there are several specific requirements for SLC recognition. We examined whether thes...

The complete nucleotide sequence of the DNA of Indian cassava mosaic virus (ICMV) and a key part of that of a group B isolate of African cassava mosaic virus from Malawi (ACMV-M) were determined and compared at the nucleotide and encoded amino acid levels with the published sequences of an ACMV group A isolate (ACMV-K) and other whitefly-transmitted gemini-viruses (WTGs). The DNA of ICMV consis...

The nucleotide sequences of the coat protein genes and 3' non-coding regions of two aphid-transmissible isolates (G2 and G7) of soybean mosaic virus (SMV) were determined. The coat protein of the G2 isolate differs from that of the aphid non-transmissible N isolate by a single amino acid at position 12 (aspartic acid in N, glycine in G2 and G7). The G7 isolate differs from G2 and N at three and...

AIMS To develop a highly sensitive and rapid protocol for simultaneous detection and differentiation of Tobacco mosaic virus (TMV) and Tomato mosaic virus (ToMV) in pepper and tomato. In this study, we use the multiplex PCR technique to detect dual infection of these two viruses. METHODS AND RESULTS A multiplex RT-PCR method consisting of one-tube reaction with two primer pairs targeted to re...

The tobacco aphid, Myzus persicae nicotianae is an economically important pest of tobacco. Damage is through direct injury by sucking sap of infested plants as well as reduction of the quality of the leaf by leaving honey-dew which encourages the subsequent growth of sooty-mould. In addition to this, aphids also transmit economically important virus diseases such as the bushy-top virus, the alf...
