“…Similarly, only strains most similar to MYMV-Vigna were detected in V. radiata and V. mungo in Southern India, and this is as was reported for Vamban (Tamil Nadu) previously (Karthikeyan et al 2004). Also, MYMIV strains were commonly detected in the East of India as previously reported by Malathi and John (2008). Although these findings may suggest a coincidence of B. tabaci Asia II 1 and MYMV-urdbean in the north of India and Asia II 8 or Asia 1 and MYMV-Vigna or MYMIV in the south and East of the country, more extensive and systematic surveying and identification of the whiteflies and viruses is required in order to confirm or refute this.…”

Identification of mungbean lines with tolerance or resistance to yellow mosaic in fields in India where different begomovirus species and different Bemisia tabaci cryptic species predominate

Mungbean (Vigna radiata (L.) Wilczek) is an important pulse crop in India. A major constraint for improved productivity is the yield loss caused by mungbean yellow mosaic disease (MYMD). This disease is caused by several begomoviruses which are transmitted by the whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae). The objective of this study was to identify the predominant begomoviruses infecting mungbean and the major cryptic species of B. tabaci associated with this crop in India. The indigenous B. tabaci cryptic species Asia II 1 was found dominant in Northern India, whereas Asia II 8 was found predominant in Southern India. Repeated samplings over consecutive years indicate a stable situation with, Mungbean yellow mosaic virus strains genetically most similar to a strain from urdbean (MYMV-Urdbean) predominant in North India, strains most similar to MYMV-Vigna predominant in South India, and Mungbean yellow mosaic India virus (MYMIV) strains predominant in Eastern India. In field studies, mungbean line NM 94 showed a high level of tolerance to the disease in the Eastern state of Odisha where MYMIV was predominant and in the Southern state of Andhra Pradesh where MYMV-Vigna was predominant, but only Eur J Plant Pathol (2017) 149:349-365 DOI 10.1007/s10658-017-1187-8 Electronic

“…Yield loss due to yellow mosaic disease in blackgram, mungbean and soybean together is estimated to be around US $ 300 million in a year [2]. Complete nucleotide sequence information of genomic components of about 25 yellow mosaic virus isolates from different regions of India and from different hosts is currently available [3]. Based on sequence identity analysis, yellow mosaic virus isolates of grain legumes are differentiated into four species, viz: Mungbean yellow mosaic India virus (MYMIV), Mungbean yellow mosaic virus (MYMV), Dolichos yellow mosaic virus (DYMV) and Horsegram yellow mosaic virus (HgYMV).…”

Infectivity analysis of a blackgram isolate of Mungbean yellow mosaic virus and genetic assortment with MYMIV in selective hosts

Yellow mosaic disease in grain legumes in Indian subcontinent is caused by two important virus species viz. Mungbean yellow mosaic virus (MYMV) and Mungbean yellow mosaic India virus (MYMIV), belonging to the genus Begomovirus of the family Geminiviridae. The genomic components of a begomovirus causing yellow mosaic disease in blackgram in southern India were cloned and sequenced. Nucleotide sequence comparison of DNA A component shows the virus isolate to be a variant of Mungbean yellow mosaic virus:-(MYMV-[IN:Vam:05]). However, DNA B component of the present virus isolate has greater similarity (92%) to Mungbean yellow mosaic India virus. Agroinoculations of the viral clones produced typical yellow mosaic symptoms in blackgram and mungbean, severe leaf curl and stunting in French bean, similar to blackgram isolate of MYMIV. Blackgram isolates of both the virus species were only mildly infectious on cowpea, produced atypical leaf curl symptoms and not yellow or golden mosaic. In agroinoculations done by exchanging genomic components, symptom expression was seen only in French bean. In cowpea, blackgram and mungbean there was no visible symptoms though viral DNA could be detected by PCR.

“…Based on several studies, it has been confirmed that at least two virus species causing YMVD are prevalent in Indian subcontinent. One of these species, mungbean yellow mosaic India virus (MYMIV) is commonly occurring in northern part of Indian sub-continent while Mungbean Yellow Mosaic Virus (MYMV) is mostly confined to peninsular region of India (Varma and Malathi, 2003;Malathi and John, 2008). These two virus species can easily be distinguished on the basis of nucleotide sequence identity (Fauquet et al, 2003).…”
