Non-invasive diagnosis of dual AV node physiology (DAVNP) in patients with AV nodal reentrant tachycardia by administration of ATP or adenosine has been reported by different authors4,5. Though many of the studies were using incremental dosage, single dose tests with ATP6 and adenosine7 have also been useful in the diagnosis of DAVNP. The test is useful in sinus rhythm to establish the presence...

Relatively little is known about the mechanisms that govern the expression of plant mitochondrial genomes. We have addressed this problem by analyzing the transcriptional activity of different regions of the maize mitochondrial genome using both in vivo and isolated mitochondrial pulse-labeling systems. The regions examined included the protein genes atpA, atp6, and coxII, the 26S, 18S, and 5S ...

The availability of mitochondrial genome sequences is growing as a result of recent technological advances in molecular biology. In phylogenetic analyses, the complete mitogenome is increasingly becoming the marker of choice, usually providing better phylogenetic resolution and precision relative to traditional markers such as cytochrome b (CYTB) and the control region (CR). In some cases, the ...

The complete mitochondrial (mt) genome of the ex-type strain Pleurocordyceps sinensis, a fungus originally isolated from Ophiocordyceps was sequenced, and assembled as single circular DNA 31,841 bp. mt encoded 15 conserved proteins (rps3, cox1, cox2, cox3, cob, atp6, atp8, atp9, nad1, nad2, nad3, nad4, nad4L, nad5, nad6), 2 rRNA (rnl rns), 25 tRNA, well 10 additional non-conserved open reading ...

Nuclear genome substitutions between subspecies can lead to cytoplasmic male sterility (CMS) through incompatibility between nuclear and mitochondrial genomes. Boro-Taichung (BT)-type CMS rice was obtained by substituting the nuclear genome of Oryza sativa subsp. indica cultivar Chinsurah Boro II with that of Oryza sativa subsp. japonica cultivar Taichung 65. In BT-type CMS rice, the mitochondr...

Megabalanus coccopoma (Darwin, 1854) is a globally invasive species in Balanomorpha (Crustacea). This model organism for studying marine pollution and ecology. However, its mitogenome remains unknown. The sequencing of M. completed the present study. It has 15,098 bp length, including 13 protein-coding genes (PCGs), 2 ribosomal RNAs (rRNAs), 22 transfer (tRNAs), along with putative regulatory a...
