The proteolipid, a hydrophobic ATPase subunit essential for ion translocation, was purified from membranes of Methanococcus jannaschii by chloroform/methanol extraction and gel chromatography and was studied using molecular and biochemical techniques. Its apparent molecular mass as determined in SDS-polyacrylamide gel electrophoresis varied considerably with the conditions applied. The N-termin...

Ascorbic acid (AsA) is an important antioxidant in plants and an essential vitamin for humans. Extending the study of AsA-related genes from Arabidopsis thaliana to Brassica rapa could shed light on the evolution of AsA in plants and inform crop breeding. In this study, we conducted whole-genome annotation, molecular-evolution and gene-expression analyses of all known AsA-related genes in B. ra...

Wallerian degeneration is the degeneration of the distal stump of an injured axon. It normally occurs over a time course of around 24 hr but it is delayed in the slow Wallerian degeneration mutant mouse (C57BL/Wlds) for up to 3 weeks. The gene, which protects from rapid Wallerian degeneration, Wld, previously has been mapped to distal chromosome 4. This paper reports the fine genetic mapping of...

Polyploidization, both ancient and recent, is frequent among plants. A "two-step theory" was proposed to explain the meso-triplication of the Brassica "A" genome: Brassica rapa. By accurately partitioning of this genome, we observed that genes in the less fractioned subgenome (LF) were dominantly expressed over the genes in more fractioned subgenomes (MFs: MF1 and MF2), while the genes in MF1 w...

Abstract Single Event Effects (SEEs) — predominately bit-flips in electronics caused by particle interactions - are a major concern for ASICs operated high radiation environments such as ABCStar ASICs, which designed to be used the future ATLAS ITk strip tracker. The chip design is therefore optimised protect it from SEEs implementing triplication techniques Triple Modular Redundancy (TMR). In ...
