Data from: Genomic analysis of codon usage shows influence of mutation pressure, natural selection, and host features on Marburg virus evolution

Izza Nasrullah, Azeem M Butt, Shifa Tahir, Muhammad Idrees & Yigang Tong
Background. The Marburg virus (MARV) has a negative-sense single-stranded RNA genome, belongs to the family Filoviridae, and is responsible for several outbreaks of highly fatal hemorrhagic fever. Codon usage patterns of viruses reflect a series of evolutionary changes that enable viruses to shape their survival rates and fitness toward the external environment and, most importantly, their hosts. To understand the evolution of MARV at the codon level, we report a comprehensive analysis of synonymous codon...

Chemical evidence of preserved collagen in a 54-million-year-old fish vertebrae

Suryendu Dutta, Sumit Kumar, Hukam Singh, Mahasin Khan, Amalan Barai, Anuradha Tewari, Rajendra Rana, Subir Bera, Shamik Sen & Ashoke Sahni
Collagens are the most abundant protein in the animal kingdom. Collagens form the structural framework of connective tissues such as bones, tendons and skin and play important biomechanical role in supporting tissue functions. The preservation of collagen in deep time is a topic of intense debate. Here we provide indisputable evidence of the presence of collagen in Early Eocene fish vertebrae using online pyrolysis-comprehensive two dimensional gas chromatography-time-of-flight mass spectrometry and immunofluorescence studies. The presence...

Biosynthesis, Characterization and Anti-dengue vector activity of Silver Nanoparticles prepared by Azadirachta indica and Citrullus colocynthis

Shafqat Rasool, Muhammad Akram Raza & Zakia Kanwal
Here, we report biosynthesis of silver nanoparticles (AgNPs) using aqueous extracts of (i) Azadirachta indica leaves and (ii) Citrullus colocynthis fruit and their larvicidal activity against Aedes aegypti. The Uv-Vis spectroscopy absorption peaks occurred in range 412-416 nm for A. indica AgNPs and 416-431nm for C. colocynthis AgNPs indicating the silver nature of prepared colloidal samples. The Scanning electron microscopy examination revealed the spherical morphology of both types of NPs with average size of 17±4...

Glaciochemistry and Pigment Producing Ability of Bacteria from the Roof of the World, the Glaciers of Karakoram, Pakistan

Noor Hassan, Muhammad Rafiq, Abdul Haleem, Naveed Iqbal, Mohsin Khan, Aamir Ali Shah & Fariha Hasan
The Karakoram Mountain Range (KMR) is one of the largest mountain ranges in the world, with ∼37% of its area glaciated. Glaciers harbor various microbes, including bacteria exposed to various extreme conditions. To thrive under these conditions, bacteria adopt various strategies, one of the most important being the production of pigments. Here, we present the geochemistry of ice, sediment and meltwaters sampled from Ghulmet, Ghulkin and Hopar glaciers of the Karakoram Range, Pakistan. In addition,...

The genetic drivers for the successful invasive potential of a generalist bird, the House crow

Farheena Iqbal
What kind of genetic structure helps the rapid range expansion of the invasive species is fundamental to understand spread of invasion. The House crow (Corvus splendens), an ecological generalist, having a large native and introduced distribution range, is a good study model to investigate the genetic structure and adaptations underpinning the evolutionary potential for successful biological invasion. Thirteen mainland and one island native population from the Indian subcontinent were studied using four nuclear introns and...

Exploring phenotypic diversity of pigmented traits and iris features in Pakistani population

Saliha Bashir, Muhammad Shafique, Muhammad Shahzad, Muhammad Sohail Anjum & Ahmad Ali Shahid
Phenotypic variations of eye color, skin color, and iris surface features have been well-explored in certain populations. However, there has been comparatively little research on variations in these features in Pakistani population. The aim of this study is to discover phenotypic diversity and correlations of pigmented traits and iris surface features in Punjab and Khyber-Pakhtunkhwa (KPK) province of Pakistan. Digital images of eyes and skin were examined by investigators to determine color using Fitzpatrick Phototype...

Veloporphyrellus latisporus, a new and noteworthy species from moist temperate forests of Pakistan

Junaid Khan, Sadiq Ullah, Hassan Sher, Muhammad Fiaz & Abdul Khalid
Veloporphyrellus latisporus is proposed as a new species based on morphological characters and supporting molecular data from ITS and LSU regions of the nuclear DNA. The new species is characterized by its red to reddish brown granulose pileus and comparatively broader basidiospores. A key to the species of Veloporphyrellus is provided. This is the first report of any Veloporphyrellus species from Pakistan.

Chioza, Holly Hardy, Gavin Arno, Sarah Hull, Muhammad Imran Khan, James Fasham, V. Gaurav Harlalka, Michel Michaelides, Anthony T. Moore, Zeynep Hande Coban Akdemir, Shalini Jhangiani, James R. Lupski … & Frans P. M. Cremers
We identified a homozygous missense alteration (c.75C>A, p.D25E) in CLCC1, encoding a presumptive intracellular chloride channel highly expressed in the retina, associated with autosomal recessive retinitis pigmentosa (arRP) in eight consanguineous families of Pakistani descent. The p.D25E alteration decreased CLCC1 channel function accompanied by accumulation of mutant protein in granules within the ER lumen, while siRNA knockdown of CLCC1 mRNA induced apoptosis in cultured ARPE-19 cells. TALEN KO in zebrafish was lethal 11 days post...

A two-step polyol process synchronized with transmetallation reduction method was used. Co-cores were synthesized by cobalt acetate and decoration of AgNPs was carried out by silver acetate. The density of AgNPs was varied...

Ethylene glycol assisted 3D floral evolution of BiFeO3-based nanostructures with effective magneto-electric response

Shahid Atiq, Syed Kumail Abbas, Ghulam Muhammad Mustafa, Murtaza Saleem, Muhammad Sufyan, Saira Riaz & Shahzad Naseem
Controlled growth of nanostructures plays a vital role in tuning the physical and chemical properties of functional materials for advanced energy and memory storage devices. Herein, we synthesized hierarchical micro-sized flowers, built by the self-assembly of highly crystalline, 2-dimensional nanoplates of Co and Ni doped BiFeO3, using a simple ethylene glycol mediated solvothermal method. Pure BiFeO3 attained scattered one-dimensional nanorods-type morphology having diameter nearly 60 nm. Co-doping of Co and Ni at Fe-site in BiFeO3...

Jorge R. Paredes-Montero, Judith Brown, Muhammad Zia-Ur-Rehman, Usman Hameed, Muhammad Haider & HansWerner Herrmann
Endosymbionts associated with the whitefly Bemisia tabaci cryptic species are known to contribute to host fitness and environmental adaptation. The genetic diversity and population complexity were investigated for endosymbiont communities of B. tabaci occupying different micro-environments in Pakistan. Mitotypes of B. tabaci were identified by comparative sequence analysis of the mitochondria cytochrome oxidase I (mtCOI) gene sequence. Whitefly mitotypes belonged to the Asia II- 1, -5, and -7 mitotypes of the Asia II major clade....
