Whole-genome characterization and comparative genomics of a novel freshwater cyanobacteria species: Pseudanabaena punensis.

Cyanobacteria are emerging as a potential source of novel, beneficial bioactive compounds. However, some cyanobacteria species can harm water quality and public health through the production of toxins. Therefore, surveying the occurrence and generating genomic resources of cyanobacteria producing harmful compounds could help develop the control methods necessary to manage their growth and limit the release contaminants into the water bodies.

In-vitro propagation, callus culture and bioactive lignan production in Phyllanthus tenellus Roxb: a new source of phyllanthin, hypophyllanthin and phyltetralin.

This is the first report on identification and quantification of important hepatoprotective and anticancer polyphenolic lignans such as phyllanthin (PH), hypophyllanthin (HPH), niranthin (NH) and phyltetralin (PT) in natural plant and in vitro cultures of Phyllanthus tenellus Roxb. The identification of lignans was carried out by Liquid Chromatography-High Resolution Mass Spectrometry (LC-HRMS) and quantified using High-Performance Liquid Chromatography (HPLC). In addition, an efficient protocol has been developed for multiple shoot induction in nodal explants of in vitro derived shoots of P.

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.

In vitro propagation and production of cardiotonic glycosides in shoot cultures of Digitalis purpurea L. by elicitation and precursor feeding.

Digitalis purpurea L. (Scrophulariaceae; Foxglove) is a source of cardiotonic glycosides such as digitoxin and digoxin which are commercially applied in the treatment to strengthen cardiac diffusion and to regulate heart rhythm. This investigation deals with in vitro propagation and elicited production of cardiotonic glycosides digitoxin and digoxin in shoot cultures of D.

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.
