Monitoring the distribution pattern and invasion status of Ageratina adenophora across elevational gradients in Sikkim Himalaya, India.

Understanding the spread intensity and population dynamics of invasive plant species is a prerequisite for developing management strategies in the Himalayan Forest ecosystems that are experiencing an accelerated rate of climate change. Although there are studies on the occurrence of few invasive species in the Himalayan ecosystems, systematic information on their intensity of spread and species association is still missing. Considering existing data gaps, we aimed to assess the intensity of spread and distribution pattern of A.

Fabrication of α-FeO Nanostructures: Synthesis, Characterization, and Their Promising Application in the Treatment of Carcinoma A549 Lung Cancer Cells.

In the present work, iron nanoparticles were synthesized in the α-FeO phase with the reduction of potassium hexachloroferrate(III) by using l-ascorbic acid as a reducing agent in the presence of an amphiphilic non-ionic polyethylene glycol surfactant in an aqueous solution. The synthesized α-FeO NPs were characterized by powder X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, atomic force microscopy, dynamic light scattering, energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and ultraviolet-visible spectrophotometry. The powder X-ray diffraction analysis result confirmed the formation of α-FeO NPs, and the average crystallite size was found to be 45 nm.

Ethnomedical Applications and Conservation Status of Leguminosae- Caesalpinioideae Plants in Uttar Pradesh, India.

Background: This review highlights the folklore, ethnomedicinal uses and conservation status of Caesalpinioideae in Uttar Pradesh (India).

Aims: It aims at compiling available data on traditional medicine, biological activity, phytochemical information and assessing the regional red list status of Caesalpinioideae in Uttar Pradesh. The information provided would help in formulating new drugs and medicines and addressing global conservation issues of such medicinally exploited species.

The internal transcribed spacer (ITS) region and trnH-psbA [corrected] are suitable candidate loci for DNA barcoding of tropical tree species of India.

Background: DNA barcoding as a tool for species identification has been successful in animals and other organisms, including certain groups of plants. The exploration of this new tool for species identification, particularly in tree species, is very scanty from biodiversity-rich countries like India. rbcL and matK are standard barcode loci while ITS, and trnH-psbA are considered as supplementary loci for plants.

Universal plant DNA barcode loci may not work in complex groups: a case study with Indian berberis species.

Background: The concept of DNA barcoding for species identification has gained considerable momentum in animals because of fairly successful species identification using cytochrome oxidase I (COI). In plants, matK and rbcL have been proposed as standard barcodes. However, barcoding in complex genera is a challenging task.
