During a taxonomic revision of Selaginella from the Himalaya which is part ongoing “Flora Pan-Himalaya” project, we studied taxonomy monospora and its closely related species. We found that S. microclada once treated as synonym should be accepted distinct In contrast, trichophylla, var. ciliolata, medogensis, effusa dulongjiangensis are reduced to synonymy based on molecular phylogenetic analys...

Assessments of the state of health of Hindu-Kush–Karakoram– Himalaya glaciers and their contribution to regional hydrology and global sea-level rise suffer from a severe lack of observations1. The globally averaged mass balance of glaciers and ice caps is negative1–3. An anomalous gain of mass has been suggested for the Karakoram glaciers2,4–6, but was not confirmed by recent estimates of mass ...

We report the generation of West Nile virus (WNV) infectious clones for the pathogenic lineage 1 Texas-HC2002 and nonpathogenic lineage 2 Madagascar-AnMg798 strains. The infectious clones exhibited biological properties similar to those of the parental virus isolates. We generated chimeric viruses and found that viral factors within the structural and nonstructural regions of WNV-TX contribute ...

To understand plant evolution and diversification, information regarding chromosome number meiotic behavior is imperative. The present study was carried out to determine the count, behavior, pollen fertility, seed set of a medicinally important Peganum harmala. Two cytotypes, diploid tetraploid are growing in western Himalaya; cytotype (2n=2x=24) Kashmir Himalaya, (2n=4x=48) Trans Ladakh. Chrom...
