The mitochondrial genome (mitogenome) characteristics of the monotypic Lasiocampoidea are largely unknown, because only limited number of mitogenomes is available from this superfamily. In this study, we sequenced the complete mitogenome of the lappet moth, Kunugia undans (Lepidoptera: Lasiocampidae) and compared it to those of Lasiocampoidea and macroheteroceran superfamilies (59 species in si...
Members of the genus Amaurobioides construct silk retreats in rock crevices of the marine spray zone, a harsh and unusual habitat for spiders. This study expands the distribution records of three morphological species of Amaurobioides found on the eastern and southern coasts of New Zealand’s South Island and uses mitochondrial DNA to examine their relationships and characterize their dispersal ...
Testosterone deficiency, as a potential risk factor for aging and aging-related neurodegenerative disorders, might induce mitochondrial dysfunction and facilitate the declines of the nigrostriatal dopaminergic system by exacerbating the mitochondrial defects and increasing the oxidative damage. Thus, how testosterone levels influence the mitochondrial function in the substantia nigra was invest...
BACKGROUND An increasing number of mitochondrial DNA (mtDNA) mutations, mainly in complex I genes, have been associated with variably overlapping phenotypes of Leber's hereditary optic neuropathy (LHON), mitochondrial encephalomyopathy with stroke-like episodes (MELAS) and Leigh syndrome (LS). We here describe the first case in which the m.4171C>A/MT-ND1 mutation, previously reported only in as...
We report on multiple patterns of differentiation and connectivity in the fanshell pearlymussel (Cyprogenia stegaria), based on different markers. Knowledge of genetic variation and genetic connectivity among remaining populations of this federally endangered species is needed to initiate implementation of the species recovery plan. We collected tissue samples from 96 specimens from the Green, ...
به دلیل سرعت بالای تکامل ژنوم هسته ای، مطالعات تکاملی بر روی ژنوم میتوکندریایی صورت می گیرد. از سوی دیگر تغییرات نوکلئوتیدی (جهش) در ژنوم میتوکندریایی یکی از مهمترین دلایل در ایجاد بیماری در مهره داران است. هدف از این پژوهش شناسایی، جداسازی و همسانه سازی ژن nd1 از ژنوم مرغ بومی خراسان و مقایسه آن با سایر توالی های ژنومی و پروتئینی این ژن به منظور بررسی جهش های احتمالی است. بدین منظور، از نمونه ...
Although there are numerous examples of animals having photoreceptors sensitive to UVA (315-400 nm) [1] and relying on UVA-based mate-choice cues [2-5], here we provide the first evidence of an animal using UVB (280-315 nm) for intraspecific communication. An earlier study showed that Phintella vittata, a jumping spider (Salticidae) from China, reflects UVB [6]. By performing six series of bina...
In recent years, as a consequence of the re-evaluation role non-Saccharomyces yeasts, several studies have been conducted on use controlled mixed fermentations with Saccharomyces and different yeast species from winemaking environment. To benefit metabolic particularities some management strain in fermentation is crucial step, particular procedures addressed to increase persistence strains duri...
