Hairy root induction and phytoremediation of textile dye, Reactive green 19A-HE4BD, in a halophyte (L.) L.

In this study, we report phytoremediation of textile dyes using hairy roots derived through (NCIM 5140) infection of in vitro leaf and stem explants of a halophyte (L.) L. Leaf explants showed higher frequency of hairy root induction (70%) than stem explants (30%), and maximum number of roots (leaf 42.

Micropropagation and non-steroidal anti-inflammatory and anti-arthritic agent boswellic acid production in callus cultures of Boswellia serrata Roxb.

Micropropagation through cotyledonary and leaf node and boswellic acid production in stem callus of a woody medicinal endangered tree species Boswellia serrata Roxb. is reported. The response for shoots, roots and callus formation were varied in cotyledonary and leafy nodal explants from in vitro germinated seeds, if inoculated on Murshige and Skoog's (MS) medium fortified with cytokinins and auxins alone or together.

Sesuvium portulacastrum (L.) L.: a potential halophyte for the degradation of toxic textile dye, Green HE4B.

Sesuvium portulacastrum is a common halophyte growing well in adverse surroundings and is exploited mainly for the environmental protection including phytoremediation, desalination and stabilization of contaminated soil. In the present investigation, attempts have been made on the decolorization of a toxic textile dye Green HE4B (GHE4B) using in vitro grown Sesuvium plantlets. The plantlets exhibited significant (70%) decolorization of GHE4B (50 mg l(-1)) that sustain 200 mM sodium chloride (NaCl) within 5 days of incubation.

Influence of growth regulators and elicitors on cell growth and α-tocopherol and pigment productions in cell cultures of Carthamus tinctorius L.

The present study examined the effects of plant growth hormones, incubation period, biotic (Trametes versicolor, Mucor sp., Penicillium notatum, Rhizopus stolonifer, and Fusarium oxysporum) and abiotic (NaCl, MgSO(4), FeSO(4), ZnSO(4), and FeCl(3)) elicitors on cell growth and α-tocopherol and pigment (red and yellow) productions in Carthamus tinctorius cell cultures. The cell growth and α-tocopherol and pigment contents improved significantly on Murashige and Skoog (MS) liquid medium containing 50.

Investigation of arsenic accumulation and tolerance potential of Sesuvium portulacastrum (L.) L.

Sesuvium portulacastrum (L.) L., a facultative halophyte, is considered a suitable candidate for the phytoremediation of metals.

In vitro culture, plant regeneration and clonal behaviour of Sesuvium portulacastrum (L.) L.: a prospective halophyte.

An efficient plant regeneration protocol using axillary shoots of the salt accumulator halophyte, Sesuvium portulacastrum (L.) L. was established and in vitro responses of six Sesuvium clones were studied.
