Theileria parva genomics reveals an atypical apicomplexan genome por Nene, Vishvanath M., Bishop, Richard P., Morzaria, S.P., Gardner, M.J., Sugimoto, C., Ole-MoiYoi, O.K., Fraser, C.M., Irvin, A.

“…Like other apicomplexan organisms, T. parva contains two extrachromosomal DNAs, a mitochondrial DNA and a plastid DNA molecule. By annotating the gnome sequence, in combination with the use of microarray technology and comparative genomics, we expect to gain significant insights into unique aspects of the biology of T. parva. …”

Telomeric features of Theileria parva mitochondrial DNA derived from cycle sequence data of total genomic DNA por Shukla, G.C., Nene, Vishvanath M.

“…The mtDNA encodes ORFs for apocytochrome b and polypeptides I and III and cytochrome oxidase, contains fragmented rRNA genes and exists as a 7.1 kbp linear DNA molecule. The mtDNA was only amenable to cloning following brief treatment with Bal31 exonuclease and partial sequence data indicated the presence of terminal inverted repeat (TIR), sequences which could have made the intact molecule refractory to cloning (1). …”

Genetic and biochemical biomarkers in the macrophyte Bidens laevis L. Exposed to a commercial formulation of endosulfan por Pérez, Débora Jesabel, Lukaszewicz, Germán, Menone, Mirta Lujan, Amé, María Valeria, Camadro, Elsa Lucila

“…Thus, cytogenetic biomarkers appear to be more sensitive to the toxic effects of the insecticide than the DNA molecule in the studied species. For this reason, the goals of this study were to use cytogenetic biomarkers—CAAT and abnormal metaphase—and defense biomarkers such as the activity of the antioxidant enzymes—guaiacol peroxidases (POD), glutathione reductase, and microsomal and cytosolic (m‐ and c‐) glutathione‐S‐transferase (GST)—to evaluate in B. laevis effects caused by a commercial formulation of endosulfan. …”

SNP genotyping by heteroduplex analysis por Paniego, Norma Beatriz, Fusari, Corina Mariana, Lia, Veronica Viviana, Puebla, Andrea Fabiana

“…The protocols involve (1) enzymatic mismatch cleavage with endonuclease CEL1 from celery, associated with fragment separation using capillary electrophoresis (CEL1 cleavage), and (2) differential retention of the homo/heteroduplex DNA molecules under partial denaturing conditions on ion pair reversed-phase liquid chromatography (dHPLC). …”

African cassava mosaic disease por Legg, James P.

“…Structurally, cassava mosaic geminiviruses (CMGs) are comprised of two small, single-stranded, circular DNA molecules, DNA-A and DNA-B, each of which is encapsidated within a geminate coat. …”

Impact of extracellular nucleic acids from lactic acid bacteria on qPCR and RT-qPCR results in dairy matrices : implications for defining molecular markers of cell integrity por Pega, Juan Franco, Descalzo, Adriana Maria, Rossetti, Luciana, Nanni, Mariana, Perez, Carolina Daiana, Rizzo, Sergio Anibal, Diaz, Gabriela Perez

“…This study suggests that, contrary to DNA molecules, mRNA from dead microorganisms or from other extracellular sources may not be a determinant factor in skewing molecular quantifications. …”

RNA silencing suppression activity encoded by plant-infecting DNA satellites from Africa por Zhou, Mi

“…Begomoviruses have a circular single-stranded (ss) DNA genome, and they often infect plants together with other circular ssDNA molecules, which are the so-called alphasatellites and betasatellites. …”

Identification and characterisation of an extrachromosomal element from a multidrug-resistant isolate of trypanosoma brucei brucei. por Jamnadass, Ramni H.

“…The 6.6 kbp element and some of the 'higher' hybridising elements display features of circular DNA molecules. The 6.6 kbp element also displays some level of size and sequence heterogeneity within different populations of the same trypanosome isolate. …”
