“…In horticultural crops, enormous losses caused by this biotic constraint have been widely recognized (Berlinger, 1986;Lapidot and Friedmann, 2002;Morales, 2011;Borah and Dasgupta, 2012). Literature available have documented that in pepper, host resistance to B. tabaci is mainly mediated by morphological traits of plants, such as leaf trichomes and leaf thickness (Firdaus et al, 2011).…”

The high diversity of chili pepper (Capsicum annuum L.) in Mexico offers an excellent alternative to search for wild and semi-domesticated genotypes as sources of resistance to the complex Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae)-Begomovirus, which has caused enormous losses in commercial production of various horticultural crops. The goal of the present work was to characterize ex situ 18 genotypes of C. annuum from southern Mexico through 47 morphological descriptors, and to evaluate its response to the B. tabaci-Begomovirus complex. Morphological characterization showed the variables calyx annular constriction (CAC), number of branch bifurcation (NBB), and calyx pigmentation (CP) had the highest variation. Principal components analysis (PCA) of 47 morphological characteristics showed that 12 components were selected as meaningful factors. These components explained 94% of the variation. Cluster analysis showed three major clusters and seven sub-clusters. On the other hand, evaluation of the response to B. tabaci-Begomovirus showed that the genotypes have differential susceptibility to this vector-pathogen complex. Genotypes 'Chawa', 'Blanco', 'Maax' and 'X´catic' were into the low susceptibility to B. tabaci and low severity of viral symptoms. Surprisingly, the genotype 'Simojovel' showed high susceptibility to whitefly, but was grouped into genotypes with low symptom severity. This study shows the potential of native germplasm of pepper to explore sources of resistance to the B. tabaci-Begomovirus complex.

“…Studies on host plant resistance to Begomovirus have been carried out in various crops, such as tomato, bean, and cassava. The outcomes of such studies have been difficult to widely adopt due to the variation in occurrence of virus strains in certain geographic areas (Borah and Dasgupta, 2012).…”

“…They are branded as monopartite (a single DNA) or a bipartite (with two DNA components: DNA-A and DNA-B) (Figure 2), based on their genome organization (Mansoor et al 2003;Jeske 2009), infecting mostly dicotyledonous plants like mungbean, urdbean and soybean (Haq et al 2011a). The two DNA components namely, DNA-A and DNA-B, are roughly 2.8 kb in size (Borah & Dasgupta 2012). Bipartite begomoviruses, namely MYMIV, MYMV and horsegram yellow mosaic virus (HgYMV), are accepted as causal agents of MYMD in different regions of the world (Qazi et al 2007;Malathi & John 2008a;Ilyas et al 2010).…”

Mungbean yellow mosaic virus (MYMV) disease is one of the most vicious diseases of green gram and has been renowned in India for more than five decades. It is caused by a group of geminiviruses belonging to the genus, begomovirus of the family, Geminiviridae. They are transmitted through whitefly in a persistent manner. The economic losses due to this virus account up to 85% in green gram which is spreading faster towards newer areas. The escalating economic importance of MYMV has resulted in the call for accurate detection and identification procedures that inspire rigorous research efforts focussing on the biology, diversity and epidemiology of the virus, so that viable management strategies could be designed. Breeding for resistance or tolerance appears to be the best approach to control this disease. However, the commercially offered genotypes are only partially resistant. Therefore, the hunt for newer sources of disease resistance needs to be intensified. This review updates all the accessible information on MYMV and outlines the areas in which advance research is indispensable.

“…MYMIV occurs in Northern India, Pakistan, Nepal, Bangladesh, and Indonesia, while MYMV is confined to Thailand, Vietnam, and Peninsular region of India (Ilyas, Qazi, Mansoor, & Briddon, 2010;Islam et al, 2012;Shahid et al, 2012;Tsai et al, 2013). HgYMV occurs only in South India (Borah & Dasgupta, 2012;Varma & Malathi, 2003). Enzyme immunoassays, ISEM, nucleic acid hybridization, and PCR-based tests were employed for the detection of begomoviruses associated with YMD of mungbean and urdbean (Malathi & John, 2008).…”
