Rice (Oryza sativa L.) is the world’s most important cereal crop. The Doairgura variety (O. a low-yielding, high-quality aromatic rice-producing in Bangladesh. This study was undertaken to develop an vitro regeneration protocol through callus induction. MS media supplemented with different concentrations of 2, 4- D (0.5, 1.0, 2.0 and 3.0 mg /l) were used for induction from mature dehusked rice ...

As documented by textbooks, the teaching of electromagnetic induction in university and high school courses is primarily based on what Feynman labeled as “flux rule,” downgrading it from status physical law. However, Maxwell derived a “general law induction” which vector potential plays fundamental role. A modern reformulation Maxwell's can be easily obtained defining induced electromotive forc...

Introduction Cumin (Cuminum cyminum L.) is a commercial plant which is valued for its aroma and its medicinal and therapeutic properties. Although India has been the primary exporter of cumin seeds and cumin oil in the world. However Turkey and Iran are providing stiff competition now. India, Turkey, Syria, China, the US, Iran, Indonesia, Sudan, Egypt, Morocco, Algeria, and Libya are the leadin...

Salvia chorassanica Bunge is one of the Iranian endemic species of Salvia. There is not any reported literature on S. chorassanica. This study was designed to examine the in-vitro anti-proliferative and proapoptotic effects of the methanol extract of S. chorassanica and its fractions on HeLa cell line. Cells were cultured in EX-CELL®, an animal free medium specially designed for HeLa cell line ...

Inoculation of Phaseolus vulgaris with Azospirillum brasilense Cd promoted root hair formation in seedling roots and significantly increased total and upper nodule numbers at different concentrations of Rhizobium inoculum. In experiments carried out in a hydroponic system, A. brasilense caused an increase in the secretion of nod gene-inducing flavonoids, as was observed by nod gene induction as...

A path reversal is performed in a rooted tree when a node becomes the root of all the nodes along the path from it to the former root. This algorithm on trees is presented as a transition system specified by induction over a convenient view of the tree structure. When each tree node is assigned a fixed weight representing its relative probability to move to the root, the transition system defin...

Introduction Andrographis paniculata is a herbaceous plant in the family Acanthaceae, native to India and Sri Lanka. It is widely cultivated in southern Asia, where it is used to treat infections and some diseases, often being used before antibiotics were created. Mostly the leaves and roots were used for medicinal purposes. Andrographis paniculata is used in traditional Siddha and Ayurvedic sy...

The morphogenic potential and free-radical scavenging activity of the medicinal plant, Silybum marianum L. (milk thistle) were investigated. Direct root regeneration and indirect organogenesis and preliminary phytochemical, antibacterial studies of its callus. From leaf explants the highly significance result was found on the NAA at 2 mg/l and KIN at 0.2 mg/l for the direct root induction and i...

A highly efficient protocol for in vitro propagation of Rauwolfia serpentina L. was developed that consisted of callus induction, multiple shoot regeneration and rooting stages. Effect of different plant growth regulators, exclusively or in combination on callus induction, multiple shoot formation and root induction, were observed. Maximum callusing (93.65%) were obtained in leaf and stem expla...
