“…Being a legume, it has the ability to fix atmospheric nitrogen (30-50 kg/ha) (Chadha, 2010). India is the leading green gram cultivator, with up to 55% of the total world acreage and 45% of total production (Rishi, 2009;Singh N et al, 2013). Green gram is a diploid (2n) with the chromosome number 22, grown primarily in intercropping with wheat, maize, potato, etc.…”

Twenty-three genotypes of green gram (Vigna radiata (L.) Wilczek) were collected to determine the extent of genetic diversity through morphological characters as well as random amplified polymorphic DNA (RAPD), inter-simple sequence repeat (ISSR), and simple sequence repeat (SSR) fingerprinting results. Analysis of variance revealed significant mean square values that indicated a substantial degree of genetic variability among the genotypes. Significant genetic variance was observed for days to 50% maturity, days to maturity, plant height (cm), number of branches/plant, number of pods/plant, pod length (cm), 1000-seed weight (g), seed yield/plant (g), biological yield (g), and harvest index (%) during cultivation in three different environments. Hierarchical Euclidean and cluster analysis based on 10 morphological characteristics grouped all 23 genotypes into three divergent clusters. RAPD (15), ISSR (13), and SSR (10) markers produced a total of 216 bands, of which 190 exhibited polymorphism. The similarity coefficients were significant for all markers; however, they were higher in ISSR than in RAPD or SSR. In the UPGMA dendrogram based on the combined morphological, RAPD, ISSR, and SSR results, the 23 genotypes were divided into three main clusters. The present study revealed that morphological and molecular markers may be successfully utilized for determining genetic diversity and relationships in green gram genotypes and could be used in green gram breeding programs.

“…Circular ssDNA eukaryotic viruses include plant pathogens from the families Nanoviridae and Geminiviridae and animal viruses from the genera Circovirus, Gyrovirus and Anellovirus (de Villiers & zur Hausen, 2009;Gronenborn, 2004;Gutierrez, 1999;Mankertz et al, 1997;Navidad et al, 2008;Noteborn & Koch, 1995;Okamoto & Mayumi, 2001). Although circular ssDNA viruses include pathogens of agricultural, veterinary and clinical concern (Almeida et al, 2009;Chae, 2005;de Villiers & zur Hausen, 2009;Moffat, 1999;Rishi, 2009;Todd, 2000), little is known about their prevalence or diversity in natural environments.…”

Single-stranded DNA (ssDNA) viruses with circular genomes are the smallest viruses known to infect eukaryotes. The present study identified 10 novel genomes similar to ssDNA circoviruses through data-mining of public viral metagenomes. The metagenomic libraries included samples from reclaimed water and three different marine environments (Chesapeake Bay, British Columbia coastal waters and Sargasso Sea). All the genomes have similarities to the replication (Rep) protein of circoviruses; however, only half have genomic features consistent with known circoviruses. Some of the genomes exhibit a mixture of genomic features associated with different families of ssDNA viruses (i.e. circoviruses, geminiviruses and parvoviruses). Unique genome architectures and phylogenetic analysis of the Rep protein suggest that these viruses belong to novel genera and/or families. Investigating the complex community of ssDNA viruses in the environment can lead to the discovery of divergent species and help elucidate evolutionary links between ssDNA viruses.
