Rhizobium inoculation has successfully been used for improving growth and yield of legume crops in different parts of the world. L-Tryptophan (L-TRP) application may further improve its effectiveness due to substrate-dependent inoculum-derived auxins in the rhizosphere. Rhizobium phaseoli strains were isolated using dilution plate technique from the mung bean nodules. Auxin biosynthesis by thes...

koelreuteria elegans, popularly known as “flame gold” is an ornamental tree. in vitro callus induction and regeneration from various explants (eaf segments and cotyledonary leaf) were studied on modified ms medium. the highest callus induction rate (80%) and multiplication was obtained in 2 mg/l 2,4-d from leaf segments. calli transferred in 1.5 mg/l bap resulted in efficient shoot regeneration...

The present study demonstrates an efficient protocol for in vitro mass propagation of A. curassavica through direct as well as indirect regeneration. The effect of MS and L2 media supplemented with various concentrations and combinations of growth regulators has been studied. The growth regulators used include BAP and kinetin (cytokinins) and IAA, IBA, NAA and 2, 4-D (auxins). MS media proved b...

Hairy root culture is a promising approach to improve production of plant secondary metabolites. The genes, which are located in T-DNA root-inducing plasmid, regulate auxin sensitivity hairy roots. Therefore, this study was aimed the growth and rosmarinic acid Lavandula angustifolia Lateral branches roots were transferred ½ MS B5 liquid media. To assess sensitivity, indole-3-acetic (IAA) indole...

1. A new method is described which gives a continuous record of the absolute rate of protoplasmic streaming in epidermal cells of the Avena coleoptile. 2. With this method a study was made of the influence of malate and iodoacetate on streaming velocity, in order to make correlations with the previously established effects of these substances on growth and respiration. 3. In the presence of opt...

1. A further study has been made of the effect of indole-3-acetic acid (auxin) on protoplasmic streaming in the epidermal cells of the Avena coleoptile. 2. The transient nature of the effect of auxin, both in accelerating and retarding streaming, is due to the temporary exhaustion of carbohydrate from the tissues. In presence of 1 per cent fructose or some other sugars the acceleration or retar...
