The present study demonstrates an efficient protocol for in vitro mass propagation of A. curassavica through direct as well as indirect regeneration. The effect of MS and L2 media supplemented with various concentrations and combinations of growth regulators has been studied. The growth regulators used include BAP and kinetin (cytokinins) and IAA, IBA, NAA(More)
The molecular fingerprinting using RAPD markers of thirteen morphological variants (off-types) and a normal from farmers’ field planted with micropropagated Robusta banana (Musa spp.) and Robusta and Grand Naine clones from authenticated source was carried out. Out of fourteen arbitrary (10-mers) primers showing intense unambiguous and reproducible(More)
Bt is a gram-positive spore forming soil dwelling bacteria with entomopathogenic properties. They produce insecticidal proteins during the sporulation phase as parasporal crystals. These crystals are predominantly comprised of Cry proteins, also called δendotoxins (regarded as environmental friendly) which are highly selective against target molecules(More)
The tea mosquito bug (TMB), Helopeltis spp. (Hemiptera: Miridae) is an insidious pest that poses a significant economical threat to tea plantations. Pseudomonas cultures are being used extensively for pest management which, however, resulting in a low mortality rate of insects and which has prompted us to search for a new microbial metabolite for TMB(More)
Asclepias curassavica like most of the medicinal plants has highest significance for its valuable secondary metabolites (glycosides and saponins). The clones produced thereof hence need to maintain their absolute genetic stability so that no unwanted variation in secondary metabolite yield can occur. Plant extracts that inhibit the growth of pathogenic(More)
Camellia sinensis (L.) Kuntze (commonly called tea plant) is an economically important cash crop in India. This plant is prone to infection by several fungal pathogens. Chitinases (EC 3.2.1.14) are enzymes that play a significant role in plants by hydrolyzing the N-acetylglucosamine polymer chitin. The present study entails different in silico(More)
The tea mosquito bug, Helopeltis (Hemiptera: Miridae), is an insidious pest that poses a significant economical threat to tea plantations. As a basic first step to control this pest is authentic identification, but the inability to determine morphological characters of Helopeltis species makes this process very difficult. DNA barcoding is a reliable(More)
