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)
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)
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)
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)
