“…It is not uncommon to observe a malformation of floral parts. Reduced pod setting in the crinkle-affected plants has been attributed to ULCD’s adverse effect on pollen fertility [ 21 , 29 ]. Leaf crinkling, witches’ broom symptoms and sterility [ 30 ], and malformation of inflorescence with proliferation of flowers with complete sterility [ 10 , 31 ] are also reported.…”

Urdbean leaf crinkle disease (ULCD) affects mainly the urdbean or blackgram (Vigna mungo (L.) Hepper) causing distinct symptoms that often result in serious yield losses. It has been known to occur for more than five decades and is considered to be of viral etiology. The identity of the causal agent, often referred to as the urdbean leaf crinkle virus, is not unequivocally proved. There are few attempts to characterize the causal agent of ULCD; however, there is no unanimity in the results. Recent attempts to characterize the causal agent of ULCD using next-generation sequencing of the virome of ULCD-affected urdbean plants indicated the involvement of cowpea mild mottle virus; however, without conforming through Koch’s postulates, the etiology of ULCD remains inconclusive. Claims of different insect vectors involved in the transmission of ULCD make this disease even more mysterious. The information available so far indicates that either two different viruses are causing ULCD or a mixture of viruses is involved. The identity of the virus/es causing ULCD still remains to be unambiguously ascertained. In this review, we attempt to analyze information on the various aspects of ULCD.

“…Among them, viral diseases are causing a drastic reduction on seed yield and quality which leads to serious economic losses (Kang et al, 2005). Urdbean leaf crinkle virus and Mungbean yellow mosaic virus frequently causing diseases on Blackgram were already reported by several researchers (Narayanasamy and Jaganathan, 1973;Srivastava, 2010;Shyam Singh and L.P. Awasthi, 2009). Ladhalakshmi (2002) reported the Tobacco streak virus (TSV) inciting stem necrosis on Blackgram and yield loss of about 20 percent in Coimbatore during 2001.…”

“…Factors such as cropping season, infection timing, and cultivars' disease resistance all had played a role in the yield loss caused by ULCD [6]. Transmission of ULCD in pulse plants is reported as possible by grafting, seed, or sap transmission [7] and through a few insect vectors [8] such as Aphis craccivora Koch (Hemiptera: Aphididae), Myzus persicae Sulzer (Hemiptera: Aphididae), Acyrthosiphon pisum Harris (Hemiptera: Aphididae), Henosepilachna dodecastigma Wiedemann (Coleoptera: Coccinellidae) [10,11] and whiteflies [12]. The transmission by different insect species is still under different investigation and confirmation.…”

Aims: To investigate the variations in total protein content and anti-oxidative enzymes in blackgram genotypes showing various levels of resistance against aphid-mediated Urdbean leaf crinkle disease (ULCD). Study Design: Completely Randomized Design. Place and Duration of Study: The studies were carried out at the Insectary belonging to the Department of Agricultural Entomology and the Centre of Innovation at Agricultural College and Research Institute, Madurai, Tamil Nadu, India in January 2021. Methodology: The research was conducted on seven blackgram genotypes exhibiting different levels of resistance to ULCD. A pot culture study was established and the test plants were subjected for inoculation of urdbean leaf crinkle virus (ULCV) via feeding by 10 viruliferous Aphis craccivora adults/plant. The alterations in the total protein content, superdioxide mutase (SOD), catalase (CAT) and peroxidase (PO) activity was estimated using spectrophotometric methods in comparison to healthy genotypes on 0, 15 and 30 days after inoculation (DAI). Results: No discernible increase in the levels of protein content was seen in either of ULCV inoculated or un-inoculated genotypes on the day of the inoculation. At post inoculation, leaf protein content of ULCV highly susceptible genotypes (VBN 8 and T9) was only marginally higher than that of resistant genotypes (CO 5 and CO 6), whereas in moderately resistant genotype (APK 1) it had only slightly increased. The SOD activity showed only a non-significant drop between inoculated versus un-inoculated plant leaves in highly susceptible VBN 8 and T9 genotypes. At 15 and 30 days post inoculation, a significantly less SOD activity was observed, but PO inversely increased compared to the latter under ULCV inoculated versus un-inoculated conditions in ULCV resistant CO 5 and CO 6 genotypes. While the susceptible ADT 5 and ADT 6 and highly susceptible VBN 8 and T9 genotypes did not show any significant increase in PO levels between inoculated versus un-inoculated conditions. Interestingly, ULCV inoculation considerably decreased the reduced CAT activity both in resistant and susceptible genotypes, when compared to the un-inoculated healthy ones. Conclusion: Fluctuations in the levels of antioxidant enzymes as well as the total protein content was significant only at 15 Days post inoculation. The ULCV infection tends to increase the total protein content in inoculated plants compared to un-inoculated plants. The aphid transmission of ULCV infection in different blackgram genotypes inflicted considerable increase in PO while decrease in SOD and CAT activities in resistant CO 5 and CO 6 genotypes.
