چکیده

Genomic components of the begomovirus causing yellow mosaic disease (YMD) in soybean in Delhi were cloned, sequenced and infectivity proved. Nucleotide sequence analysis of the virus isolate revealed more than 89% identity with Mungbean yellow mosaic India virus (MYMIV) and therefore it is designated as soybean isolate of MYMIV (MYMIV-[Sb]). Total nucleotide and predicted amino acid sequence analysis of MYMIV-[Sb] with other yellow mosaic virus isolates infecting legumes established dichotomy of the isolates into two species namely MYMIV and mungbean yellow mosaic virus (MYMV). Involvement of at least two distinct viruses in the etiology of soybean YMD in India is indicated here.

Linkage mapping of Mungbean yellow mosaic India virus (MYMIV) resistance gene in soybean

Mungbean Yellow Mosaic India Virus (MYMIV) is one of the most prevalent pathogen that limits soybean production in India. In this study RILs derived from JS335, dominant but MYMIV susceptible variety and PI171443, donor of MYMIV resistance gene in most of the MYMIV resistant varieties released in India and F2 population derived from SL525, a resistant variety released for northern India and NRC...

Genetic diversity and phylogeography of begomoviruses infecting legumes in Pakistan.

Grain legumes are an important source of dietary protein across southern Asia, but they suffer extensive losses due to several viruses that are members of the genus Begomovirus (family Geminiviridae), which are collectively known as legume yellow mosaic viruses (LYMVs). Despite their economic importance, little attention has been paid to LYMVs in Pakistan and only partial sequences of virus iso...

RNAi-derived transgenic resistance to Mungbean yellow mosaic India virus in cowpea

Cowpea is an important grain legume crop of Africa, Latin America, and Southeast Asia. Leaf curl and golden mosaic diseases caused by Mungbean yellow mosaic India virus (MYMIV) have emerged as most devastating viral diseases of cowpea in Southeast Asia. In this study, we employed RNA interference (RNAi) strategy to control cowpea-infecting MYMIV. For this, we generated transgenic cowpea plants ...
