A large number of spliceosomal proteins are required for proper RNA splicing. While spliceosomal proteins from several model organisms have been analysed, only limited studies are available for fungal species. Hence, we have performed a comparative genomic analysis using eight fungal species belonging to three taxa (Ascomycetes, Basidiomycetes and Glomeromycota). We identified variable number of spliceosomal proteins in fungal species. From the small nuclear ribonucleoproteins (snRNPs), all the snRNPs were identified. In non-snRNPs, only some sub-groups were found extensively conserved in all fungal species, including PRP19 complex proteins, catalytic step II and late-acting proteins. In heterogeneous nuclear ribonucleoproteins (hnRNPs), variable number of proteins was identified. The number of spliceosomal proteins identified in filamentous fungi was higher than that in yeast. The collection of these spliceosomal proteins provides further insight into pre-mRNA splicing in fungi.Keywords

Alpha Particle X-ray Spectrometer (APXS) is one of the two scientific experiments on Chandrayaan-2 rover named as Pragyan. The primary scientific objective of APXS is to determine the elemental composition of the lunar surface in the surrounding regions of the landing site. This will be achieved by employing the technique of X-ray fluorescence (XRF) spectroscopy using in situ excitation source 244Cm emitting both X-rays and alpha particles. These radiations excite characteristic X-rays of the elements by the processes of particle induced X-ray emission and XRF. The characteristic X-rays are detected by the ‘state-of-the-art’ X-ray detector known as Silicon Drift Detector, which provides high energy resolution, as well as high efficiency in the energy range of 1–25 keV. This enables APXS to detect all major rock forming elements such as, Na, Mg, Al, Si, Ca, Ti and Fe. The flight model of the APXS payload has been completed and tested for various instrument parameters. The APXS provides energy resolution of ~135 eV at 5. 9keV for the detector operating temperature of about –35°C. The design details and the performance measurement of APXS are presented in this paper.Keywords

Fine roots (diameter less than 2 mm) comprise a significant portion of the plant biomass. They are important for water absorption, cycling of nutrients and the carbon budget on a global scale. The aim of the present study was to quantify fine root biomass in the Nainital district, Central Himalaya, India, which has several dominant forest types. A total of 81 samples were collected from nine sample plots for each forest type in three distinct directions. The results showed that sal forest (1.11 0.04 t ha–1) had the largest fine root biomass, followed by oak forest (0.72 0.06 t ha–1) and pine forest (0.61 0.06 t ha–1). We observed that the trend in fine root biomass across different forest types was as follows: sal forest > oak forest > pine forest, significant at 0.05 level. Fine root biomass was also observed to decrease similarly with increasing soil depth in each forest type, following the trend: 0–20 cm > 20– 40 cm > 40–60 cm, which was significant at 0.05 level. Researchers will benefit from this study since it will help them comprehend fine root biomass variation and offer baseline data for future research on nutrient cycling and the global carbon budget.Keywords
