An improved micropropagation method has been developed for Salvadora oleoides, a valuable tree species of alkaline and arid regions. Nodal explant obtained from a mature tree (30- to 35-year-old) responded optimally (80.0 %) on BAP (2.0 mg l−1) and produced (4.56 ± 0.52) shoots. Shoots were further multiplied by subculturing the in vitro excised shoots and(More)
Th17 cells are characterized as preferential producer of interleukins including IL-17A, IL-17F, IL-21 and IL-22. Corresponding receptors of these cytokines are expressed on number of cell types found in the mucosa, including epithelial cells and fibroblasts which constitute the prime targets of the Th17-associated cytokines. Binding of IL-17 family members(More)
Bacterial toxin-antitoxin (TA) complexes induce programmed cell death and also function to relieve cell from stress by various response mechanisms. Escherichia coli RelB-RelE TA complex consists of a RelE toxin functionally counteracted by RelB antitoxin. In the present study, a novel homolog of RelE toxin designated as Xn-relE toxin from Xenorhabdus(More)
A micropropagation method using liquid culture medium has been developed for mature Acacia nilotica (L.) Del. ssp. indica. Nodal segments obtained from 15 to 20 years old mature trees were used as explants and cultured on 0.8 % agar-gelled Murashige and Skoog medium containing 6-benzylaminopurine for shoot bud induction. Once culture got established,(More)
Factors affecting somatic embryogenesis from immature cotyledon of gum arabic tree [Acacia senegal (L.) Willd.] were investigated. Induction of somatic embryogenesis was influenced by plant growth regulator concentrations and addition of amino acids in medium. Best induction of somatic embryogenesis was obtained on MS medium supplemented with 0.45 μM 2,(More)
A micro-propagation method using liquid culture medium has been developed for Acacia nilotica ssp. cupressiformis. Nodal segments obtained from mature tree (15–20 years old) was used as explants for bud breaking and multiple shoot induction. MS liquid medium with 2.0 mg l−1 of 6-benzylaminopurine (BAP) was the best for shoot bud induction. Further shoots(More)
Xenorhabdus nematophila, a gram-negative bacterium belonging to the family Enterobacteriaceae is a natural symbiont of a soil nematode from the family Steinernematidae. In this study cloning, expression, and purification of broad range iron regulated multidomain bacteriocin called xenocin from X. nematophila (66 kDa, encoded by xcinA gene) and its(More)
Polysiloxane-encapsulated "Pd"-nanoclusters were generated by reduction of Pd(OAc)(2) with polymethylhydrosiloxane, which functions as a reducing agent as well as a capping material for production and stabilization of catalytically active "Pd"-nanoparticles. Chemoselective hydrogenation of functional conjugated alkenes was achieved by in-situ- or(More)
Toxin-antitoxin (TA) complexes play an important role in stress responses and programmed cell death in bacteria. The RelB-RelE toxin antitoxin system is well studied in Escherichia coli. In this study, we used combined in silico and in vitro approaches to study a novel Xn-RelT toxin from Xenorhabdus nematophila bearing its own antitoxin Xn-RelAT-a RelB(More)
This article focuses on a relatively new group of organosilicon polymers known as cyclolinear polycarbosilanes (CLPCS). This group of polymers contains 1,3-disilacyclobutane (DSCB) rings, i.e., cyclo-{RSi(CH(2))(2)SiR}-, bridged by various linking groups, so as to form linear chains with regularly spaced, strained, rings that function as latent sites for(More)
