During in vitro multiplication and rooting of Vriesea splendens ’Fire’, 0.1, 0.2, 0.4 0.8 mg l-1 benzyladenine (BAP), benzyladenine-riboside (BAPR), kinetin (KIN), meta-topoline (MT), indole-butyric acid (IBA) naphthalene-acetic (NAA) were added to basal Murashige Skoog (1962) MS medium. As compared the hormone-free control, plants developed significantly more shoots on medium supplemented with...

To date, several classes of hormones have been described that influence plant development, including auxins, cytokinins, ethylene, and, more recently, brassinosteroids. However, it is known that many fungal and bacterial species produce substances that alter plant growth that, if naturally present in plants, might represent novel classes of plant growth regulators. Alkamides are metabolites wid...

A liquid overlay culture system in micropropagation improved shoot proliferation many species. In the present investigation, we have developed an enhanced protocol using double phase (DPS) for Vanilla andamanica, endemic species of Andaman and Nicobar Islands recognized under vulnerable category by IUCN. vitro generated nodal explants were used experiments tested Murashige Skoog medium augmente...

A rapid and efficient in vitro propagation protocol of Acorus calamus L. an important endangered medicinal plant has been developed. Naturally grown rhizome segments were used as explants for initial culture. Surface sterilized rhizome segments were cultured on Murashige and Skoog (MS) medium supplemented with various concentrations (0.5 mg l 3.0 mg l ) of cytokinins (BAP, Kn) and auxins (IAA, ...

Tea (Camellia sinensis L), is a popular agricultural product enjoyed by people around the world. Bio-fertilizers that use bacteria found in soil called endophytes, have proven effective for increasing growth and plant productivity. Endophite can also produce hormones such as auxins, ethylene, cytokinins. This research aims to determine effectiveness of auxin-producing endophytic bacterial micro...

Until recently, there were rare scientific reports on the biotechnological potential of non-pathogenic bacteria Acinetobacter genus. Although first about practically valuable properties these date back to 70s and 80s twentieth century concerned synthesis emulsan bioemulsifier. In last decade, interest in representatives genus as objects biotechnology has significantly increased. The review pres...

Peroxiredoxins (Prxs), thioredoxins (Trxs), and NADPH-thioredoxin reductases (NTRs) constitute central elements of the thiol-disulfide redox regulatory network of plant cells. This study provides a comprehensive survey of this network in the model legume Lotus japonicus. The aims were to identify and characterize these gene families and to assess whether the NTR-Trx systems are operative in nod...
