toxoplasma gondii is one of the most prevalent parasitic infections in world. rh, ned and me49 are of the most prevalent clonal types of the parasite isolated till now. differences in pathogenicity and virulence of different types have been investigated in different studies. no controlled study was performed to compare the ability of different types to initiate humoral immune response. we inves...

Presence of pharmaceutically important alkaloids in various parts of the plant body made Rauvolfia serpentina an overexploited one and led to its inclusion in Red Data Book of India as an endangered species. Conventional propagation is beset with problems like poor seed viability, low seed germination rate and delayed rooting of cuttings. In vitro clonal propagation may therefore be beneficial ...

Background Modern forest management relies on extensive breeding and reforestation programs to sustain forest productivity and conservation of natural forests. Plantation forestry, with its increased productivity and improved wood quality, is likely to become an important source of wood products in the future. Vegetative propagation of superior coniferous forest trees through tissue culture has...

A method of in vitro clonal propagation of cowslip Primula veris L. (Primulaceae) is reported. This is a species of medicinal importance, protected by law in Poland. MS medium Murashige and Skoog (1962) with 6 benzyladenine BA (4.44 μM) and 2,4-dichlorophenoxyacetic acid 2,4-D (1.13 μM) was found to be optimal for in vitro cowslip propagation from shoot tips under the conditions of culture. Roo...

Ranunculus wallichianus is a medicinally important plant and an endemic species to the Western Ghats of South India. An efficient reliable indirect regeneration protocol system for R. was developed from leaf explants in present investigation. Leaf were cultured on both full-strength half-strength MS (Murashige & Skoog) medium supplemented with different concentrations (0.5 mg L− 1 3.0 1) 2,4-D ...

We study front propagation when an invading species competes with a resident; we assume nearest-neighbor preemptive competition for resources in an individual-based, two-dimensional lattice model. The asymptotic front velocity exhibits an effective power-law dependence on the difference between the two species' clonal propagation rates (key ecological parameters). The mean-field approximation b...

This study describes the standardization of an efficient in vitro propagation and hardening procedure for obtaining plantlets from shoot tips of Hemp (Cannabis sativa L.). Hemp seedlings were germinated on half-strength 1/2 MS medium supplemented with 10 g·Lsucrose, 5.5 g·Lagar at a pH of 6.8 under light for 16 h per day. MS medium containing 0.2 mg·LTDZ, 0.1 mg·LNAA supported the maximal auxil...

The quest for alternative matrices plant tissue culture is a continuing process. Agar one of the utmost common coagulating agents in in vitro clonal propagation. Pure grade agar has high value price and fear over manipulation its resources affected searching low cost options. Therefore, liquid medium supplement with silica gel, glass beads sands substratum two steps micro propagation (se...

Abstract Pears (Pyrus) are one of the most economically important fruits worldwide. The Pyrus genus is characterized by a high degree genetic variability between species and interspecific hybrids, several studies have been performed to assess this for both cultivated wild accessions. These mostly limited resolving power traditional molecular markers, although in recent past availability referen...
