“…Maruthi et al (2006) characterized the DoYMV isolates from Mysore and Bangalore and reported that their isolates shared 92.5 to 95.3% identity with previously described isolates from North India and Bangladesh [17]. Akram et al (2015) characterized full genome of DoYMV isolate from Kanpur (Accession No:KJ481204) which revealed 93 to 96% identity with DoYMV isolate sequences available in database [3]. From the perusal of literature and our own study it can be inferred that DoYMV isolates are highly homogenous across different parts of The most significant result of the study is the detection of DoYMV in seed parts.…”

Yellow mosaic disease in field bean caused by begomoviruses belonging to the family Geminiviridae is a major threat to the cultivation of crop in South India. Appearance of bright yellow mosaic symptom in emerging seedlings in farmers field was suggestive of seed transmission of the begomovirus associated with the disease which was investigated in the present study. The begomovirus causing yellow mosaic disease was identified as dolichos yellow mosaic virus (DoYMV) and the presence of DoYMV in matured seeds was confirmed by DAS-ELISA with OD value up to 3.268. In PCR with DoYMV specific primer (DoYMV-CP) the virus was detected in different parts of the seeds viz., seed coat, endosperm and embryo. In embryo the virus was detectable up to 100 per cent followed by endosperm (69.23%). When the non symptomatic leaves of 30 days old grow-out test plants were subjected to DAS-ELISA, the virus was detected up to 46.6%. This is the first evidence of seed transmission of DoYMV.

“…The incidence of DoYMV has increased by 40% post-1990s. Since it was first recorded in 1950 by Capoor and Varma, the etiology, epidemiology, diagnostics, and host plant resistance of DoYMV have been reported by several workers (Yaraguntaiah and Govindu, 1964;Ramakrishnan et al, 1972;Raj et al, 1988;Harrison et al, 1991;Swanson et al, 1992;Maruthi et al, 2005Maruthi et al, , 2006Akram et al, 2015). Infected plants produce characteristic yellow mosaic symptoms similar to mungbean yellow mosaic virus (MYMV) and mungbean yellow mosaic India virus (MYMIV), but DoYMV does not infect black gram, cowpea, French bean, green gram, and soybean (Maruthi et al, 2006).…”

“…Infection at an early stage of crop growth often leads to total yield loss. DNA-A of DoYMV consists of 2,761 nucleotides that indicate the presence of six ORFs typical of Old World begomoviruses ( Akram et al, 2015 ; Suruthi et al, 2018 ). DoYMV DNA-A shows nearly 63% nucleotide identity with MYMV and MYMIV and lower identities with other begomoviruses ( Maruthi et al, 2005 ).…”

Transovarial Transmission of Dolichos Yellow Mosaic Virus by Its Vector, Bemisia tabaci Asia II 1

et al. 2021

The cultivation of dolichos bean [Lablab purpureus (L.) Sweet] has been severely affected by dolichos yellow mosaic virus (DoYMV, Begomovirus) transmitted by whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae). We tested the transovarial transmission of DoYMV in next-generation B. tabaci by PCR, real-time PCR, Southern blot hybridization, and biological transmission. The eggs, laid by DoYMV-exposed B. tabaci, carry the virus in a unique pattern. Only the eggs laid in between 3 and 6 days post virus acquisition by a parent B. tabaci were DoYMV positive. When tested individually in real-time PCR, around 31–53% of the eggs carried the virus. The presence of DoYMV in ovaries and F1 eggs was further substantiated by the hybridization of a Cy3-conjugated nucleic acid probe complementary to the viral strand of DoYMV. Viral DNA was also detected in F1 adults and F2 eggs. B. tabaci progenies carried not only the DoYMV DNA but were also infective. The F1 adults transmitted DoYMV to all tested plants and produced strong yellow mosaic symptoms. An increase in viral copies from egg to nymphal stage indicated propagation of DoYMV in B. tabaci. However, the increase was for a short period and decreased thereafter. The present study provides the first evidence of transovarial transmission and propagation of a bipartite begomovirus in its vector, B. tabaci Asia II 1. The transovarial transmission and replication of DoYMV in B. tabaci have great epidemiological relevance as B. tabaci can serve as a major host of the virus to bridge the gap between the cropping seasons.

Begomoviruses are transmitted by the whitefly Bemisia tabaci (Gennadius) (Hemiptera, Aleyrodidae) in a persistent circulative manner (Markham et al 1994).…”

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
