Chloroplast genome analysis of Chrysotila dentata.

Chrysotila dentata is an ecologically important marine alga contributing to the coccolith formation. In this study, a complete chloroplast (cp DNA) genome of Chrysotila dentata was sequenced by using Illumina Hiseq and was analyzed with the help of a bioinformatics tool CPGAVAS2. The circular chloroplast genome of Chrysotila dentata has a size of 109,017 bp with two inverted repeats (IRs) regions (4513 bp each) which is a common feature in most land plants and algal species.

Comparative Cytotoxic Activity of Wild Harvested Stems and Raised Protocorms of Rolfe in Human Cervical Carcinoma and Glioblastoma Cell Lines.

From the medicinal orchid Rolfe, which is used in traditional and folk Chinese medicine, the protocorms were raised in Murashige and Skoog (MS) media in three strengths, full strength (FMS), half strength (1/2 MS), and quarter strength (1/4 MS), with or without the phytohormones 6-benzylaminopurine (BAP) and 1-naphthaleneacetic acid (NAA) and coconut water (CW). The comparative cytotoxic activities of the wild and -raised protocorms were evaluated in human cervical carcinoma (HeLa) and human glioblastoma (U251) cell lines by MTT assay. In and , the methanol extracts of showed significant cytotoxic activities.

Cytotoxic effect of selected wild orchids on two different human cancer cell lines.

Majority of the orchid species are used in the traditional medicines for the treatment of several diseases. They are the sources of polysaccharides, phenanthrenes, bibenzyl derivatives, revesteral, stilbenoids and polyphenol compounds. This study explored the cytotoxic activity of seven wild orchid species and identification of medicinally active compounds.

Piriformospora indica promotes the growth of the in-vitro-raised Cymbidium aloifolium plantlet and their acclimatization.

Cymbidium aloifolium is known for its ornamental and medicinal values. It has been listed as threatened orchid species. In this study, in vitro propagated C.

Production of virus-free orchid (L.) Sw. by various tissue culture techniques.

Orchids are affected by many viruses resulting in poor growth, yield and quality, and an overall decline in population. Cymbidium mosaic virus (CymMV) is one of the common orchid viruses found in species but it infects different orchid genera. In this study was propagated using MS medium at different strength (1.
