Article Abstract
Zanthoxylum armatum DC. is a plant with many medicinal values which is extensively used in traditional system of medicine for curing various diseases and ailments, including cancer. The aim of the present study is to identify Zanthoxylum armatum collected from different parts of Manipur, India, at molecular level. Molecular markers like internal transcribed spacer (ITS) region and other DNA barcoding genes such as matK, rbcL, psbA-trnH and trnL-trnF were targeted to find out the most suitable DNA barcode for identifying this species. Sequences obtained using the five primer pairs-ITS An5 and ITS An4, matK-413f-1 and matK-1227r-1, rbcL-1F and rbcL-724R, psbA-F and trnH-R and trnL-F and trnF-R were submitted to GenBank, NCBI. Amongst the five DNA barcoding targets, one nuclear and four chloroplast genes were successfully amplified by PCR (100%) and sequencing (100%) in all the eight plant samples. Sequence similarity of total ITS region (620 bp) when compared to the reference sequence were found to be between 98.55 and 99.68%. In our study, ITS sequence in combination with DNA barcoding sequences of rbcL, trnH-psbA and trnL-trnF was very successful in identification of Z. armatum and differentiate other species clearly in the phylogeny analysis. Our work shows ITS region to be the most suitable DNA barcode which formed a monophyletic group of the species in the phylogenetic tree analysis. The sequences of the barcoding genes of Z. armatum DC. obtained from this study adds to the already available resources which will be helpful in the future research endeavours.

Wildlife poaching and the trade of wildlife items is a large area of illegal business that is alleged to be worth hundreds of billions of dollars. However, wildlife forensics remains an understudied field even though the consequences of poaching are catastrophic and can lead to the spread of zoonotic disease and a decrease in biodiversity. Even though fingermark analysis is cost-effective, easy to deploy in the field and has a long history of securing criminal convictions in court, wildlife forensics is mainly limited to DNA-based techniques.

Mutations in the UBE3A gene are responsible for neurodevelopmental disorders (NDDs), including Angelman syndrome (AS), which is characterized by developmental delays, impaired motor coordination, and cognitive disabilities. In recent years, UBE3A mutations have also been linked to autism spectrum disorders (ASD), due to their significant role in synaptic plasticity and cognitive function. Although substantial research has utilized mammalian models, the zebrafish (Danio rerio) provides unique opportunities to investigate gene functions owing to their transparent embryos, rapid development, and suitability for large-scale genetic and behavioral studies.

An imino-linked dansyl-carbazole molecular system, DASH, is designed and synthesized. This system (DASH) is rationalized in such a way that it works as a suitable template for the detection of date rape drugs, gamma-butyrolactone (GBL) and gamma-valerolactone (GVL), in addition to latent fingerprint detection. Both rape drug and latent fingerprint detection are important aspects of drug abuse-related crimes in forensic analysis.

Recombinant DNA technology is widely used to produce industrially and pharmaceutically important proteins. In silico analysis, performed before executing wet lab experiments has been greatly helpful in this connection. A shift in protein analysis has been observed over the past decade, driven by advancements in bioinformatics databases, tools, software, and web servers.

To date, environmental conditions have been enough to act as an effective barrier to prevent non-indigenous species from arriving and establishing in Arctic Canada. However, rapidly changing climatic conditions are creating more suitable habitats for non-indigenous species to potentially establish and become invasive. Concurrently, shipping traffic in parts of Arctic Canada has increased by over 250% since 1990, providing an effective vector for transporting non-indigenous species to the region.
