“…Yellow mosaic disease (YMD) incidence ranged from 3.73 (DKU-87) to 96.15% Bag et al, 2014;Gopi et al, 2016). Shad et al (2006) and Prasanthi et al (2013) observed that blackgram genotypes with MYMV symptoms at early age of the crop were found to be susceptible with high PDI than resistant genotypes and the present results are in accordance with the earlier reports.…”

“…Lowest value indicated small amount of cumulative disease progress that resulted in delay in the onset and severity of symptom development (Raju and Anilkumar, 1990). The highest AUDPC value (2402.7) was reported in blackgram susceptible check Barabanki Local (Bag et al, 2014) which corroborate with the present results. In mungbean the highest AUDPC value was reported in susceptible genotype, HUM-12 compared to resistant genotypes ).…”

Sixteen blackgram genotypes were tested for yellow mosaic disease under field conditions and identified nine genotypes as resistant, one as moderately resistant, four as susceptible and two as highly susceptible. No genotypes were found to be immune or highly resistant against yellow mosaic disease. Polymerase Chain reaction (PCR) of DNAs from sixteen genotypes using Sequence Characterized Amplified Region (SCAR) markers namely, SCAR 20F/20R resulted in specific amplification in nine genotypes indicating resistant nature of these genotypes. There was no amplification in six genotypes while faint amplification could be observed in the genotype LBG-752 that recorded 14.47% incidence of the disease along with moderately phenotypic reaction.

“…Due to the non-availability of diverse resistant sources to YMD, most of the commercially available cultivars were derived from a few resistant sources [ 12 , 14 ], which has resulted in a narrow genetic base, especially for the YMD resistance. Long-term improvement of mungbean production needs uncovering of the molecular mechanisms of YMD resistance and its use for realizing the potential yield.…”

Yellow Mosaic Disease (YMD) in mungbean [Vigna radiata (L.) R. Wilczek] is one of the most damaging diseases in Asia. In the northern part of India, the YMD is caused by Mungbean Yellow Mosaic India Virus (MYMIV), while in southern India this is caused by Mungbean Yellow Mosaic Virus (MYMV). The molecular mechanism of YMD resistance in mungbean remains largely unknown. In this study, RNA-seq analysis was conducted between a resistant (PMR-1) and a susceptible (Pusa Vishal) mungbean genotype under infected and control conditions to understand the regulatory network operating between mungbean-YMV. Overall, 76.8 million raw reads could be generated in different treatment combinations, while mapping rate per library to the reference genome varied from 86.78% to 93.35%. The resistance to MYMIV showed a very complicated gene network, which begins with the production of general PAMPs (pathogen-associated molecular patterns), then activation of various signaling cascades like kinases, jasmonic acid (JA) and brassinosteroid (BR), and finally the expression of specific genes (like PR-proteins, virus resistance and R-gene proteins) leading to resistance response. The function of WRKY, NAC and MYB transcription factors in imparting the resistance against MYMIV could be established. The string analysis also revealed the role of proteins involved in kinase, viral movement and phytoene synthase activity in imparting YMD resistance. A set of novel stress-related EST-SSRs are also identified from the RNA-Seq data which may be used to find the linked genes/QTLs with the YMD resistance. Also, 11 defence-related transcripts could be validated through quantitative real-time PCR analysis. The identified gene networks have led to an insight about the defence mechanism operating against MYMIV infection in mungbean which will be of immense use to manage the YMD resistance in mungbean.

“…Over the three consecutive years of this study, only yellow mosaic strains most similar to MYMV-Urdbean were detected in V. radiata, V. mungo and G. max in the North of India, whereas Bag et al (2014) had previously detected both MYMVand MYMIVat the New Delhi site. 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).…”

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

et al. 2017

View full text Add to dashboard Cite

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
