Kinetic Characterization and Partial Purification of Peroxidase in Eucalyptus F1 Hybrids

A differential pattern of peroxidase (E.C. 1.1.11.7) has been observed in reciprocal F1 hybrids of Eucalyptus (FRI-4 and FRI-5) produced using parental combination of E. tereticornis and E. camaldulensis. The hybrids were characterized for the qualitative, kinetic parameters (total and specific activity, units, Km and Vmax) and partial purification of peroxidase. The qualitative study showed the presence of high molecular weight peroxidase isoforms i.e. 260 KD, 250 KD and 110KD bands. A strong maternal inheritance was observed for 260 KD loci in FRI-5. Kinetic characterization of peroxidase revealed that F1 genotypes had efficient peroxidase system over their parental combination resulting in 8 -10 times more heterotic vigour. The FRI-5 genotypes were found to be having efficient peroxidase system with lowest Km values (0.12mM-0.17mM) and higher Vmax values ranging from 0.07-0.14mM min-1mg prot-1. The study revealed the role of maternal inheritance and was found that better genotypes are produced when superior parents are used as seed parent. The results suggest the efficient use of peroxidase marker for the identification of the better genotypes in forest tree species. &nbsp

Emergence of Lumpy Pox Virus and Their Preventive Measures: A Global Livestock Threat

In the last few years viral disease not only affect the human but also the other life on this planet and result epidemic condition at global level. The highly transmissible viral disease called Lumpy skin disease (LSD) spread in sequential manner at worldwide level affecting the cattle or dairy animals of caprine, ovine and bovine family. The highly mutational efficiency of this viral strains affects the large-scale population and still no effective cure for it. Different vaccines designed at national and international level as a preventive measure to overcome the reoccurrence of this virus e.g., Bovivax-LSD™, Lumpivax™, Poxvac™, Lumpi-ProVacInd. However, still the mortality of LSD are low, not affect humans but emergence of the mutational variants demands novel vaccines

Micropropagation And Antimicrobial Activity Of Callicarpa Macrophylla (Priyangu) Against Medically Important Pathogens

Callicarpa macrophylla (Priyangu) a medicinally important plant, represents a class of herbal drug with very strong conceptual and traditional base. In present study extract of leaf, stem showed less antimicrobial activity than seed. They showed antimicrobial activity against three bacterial strains Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Pseudomonas and three fungal Strains Aspergillus fumigatous, Rhizopus oryzae and Aspergillus awamori. Maximum activity was observed in ethanol extract of leaf and stem, Methanol extracts of seed. Phytochemical analysis of the plant extract revealed the presence of phenol, reducing sugar, coumarin and saponins.  Micropropogation of C.macrophylla was done using stem as a explant material on MS and Woody media. Which revealed that woody media containing BAP (6-amino benzyl purine) NAA(α-napthaleneacetic acid) gave maximum proliferation  response in comparison to MS media. Plant extract (leave, stem and seed) have provide protection against RBC haemolysis and protein denaturation may act as anti-arthritic agent. We propose antiarthritic and antimicrobial activity of C.macrophylla

Quantitative Determination and Source Variation of Rutin in Fagopyrum Tataricum

Buckwheat (Fagopyrum sp.) is a traditional crop of Uttarakhand (India) known for its high Rutin content, a bioflavonoid with significant medicinal properties. This study explores the quantitative measurement of Rutin in various buckwheat varieties grown in different regions of Uttarakhand using Thin Layer Chromatography (TLC) and High-Performance Thin Layer Chromatography (HPTLC). Twelve seed sources of Fagopyrum tataricum from the Garhwal and Kumaon regions, along with Fagopyrum esculentum seeds for comparison, were collected. Preliminary phytochemical screening of the extracts revealed the presence of flavonoids, alkaloids, tannins, and carbohydrates, with methanolic extracts showing higher concentrations. TLC analysis was employed to determine the most effective solvent system for Rutin separation, leading to the identification of three samples with substantial Rutin content. HPTLC was then used for quantitative Rutin assessment, with a calibration curve established using standard Rutin solutions. The three selected samples, along with the standard, were applied to HPTLC plates, and the Rutin content was measured based on peak areas and peak heights. The sample collected from Joshimath, Uttarakhand, known as "JOG," exhibited the highest Rutin content. This study provides valuable insights into the phytochemical composition of buckwheat varieties in Uttarakhand, which can inform the development of high-quality functional foods. Rutin, a potent antioxidant with various health benefits, underscores the significance of buckwheat as a naturally occurring functional food source. The results contribute to understanding the Rutin-rich potential of buckwheat grown in Uttarakhand and its applications in functional foods and nutraceuticals. Further research in this field can promote the cultivation and utilization of buckwheat as a source of this valuable bioactive compound with numerous health benefits

Studies on the Analgesic Potential of leaf Extracts of Allium humile on Swiss albino mice

Allium humile is a medicinal plant found at the Alpine Himalayas of Uttarakhand at altitute of 2500-3000 meters height of sea level. In India, Allium humile, is used by local people as a spice and in ethano-medicine. In the present study, Allium humile leaves were explored for their analgesic potential on experimental model and compared to standard drugs. Allium humile at the doses of 100 mg/kg and aspirin 25 mg/kg exhibited significant (p>0.05) inhibition of the control writhes at the rate of 64.25%, 44.54%, 44.54% and 59.89% respectively when compared to that of control. Thus, methanolic extract of the plant can be fully explored for its analgesic potential which has not been reported so far. The plant extract showed a relative low toxicity hence justifies the folkloric use of plant by the local people in Western Himalayan region for curing inflammation and painful conditions

Cannabis sativa L.: a potential natural reservoir of sugarcane grassy shoot phytoplasmas in India

Cannabis sativa plants growing nearby sugarcane fields affected with grassy shoot disease at Muzaffarnagar, Uttar Pradesh, India, showed severe witches’ broom symptoms. The DNA from symptomatic Cannabis and sugarcane samples was isolated and subjected to nested PCR assays with universal phytoplasma-specific primer pairs (P1/P7 and R16F2n/R16R2). A DNA fragment of ~ 1.2 kbp was amplified in all the symptomatic samples of sugarcane and Cannabis with R16F2n/R16R2 primer pair but was absent in non-symptomatic samples. Pairwise sequence comparison, phylogeny and in silico RFLP analysis of 16S rDNA sequences confirmed the identity of a rice yellow dwarf phytoplasma group-related strain (16SrXI-B) associated with Cannabis which suggested its role as potential natural reservoir of SCGS phytoplasma in nature
