Different types of microbes playing important role in soil fertility, increase the food production both agricultural and economical point of view. Plant activities such as phytoremediation efficiency in the form root symbiosis formation by assisting the removal the toxic metals for the formation of rhizosphere. Once the pathogen enters into the plants through different routes, different immune responses elicited as plants show a variety of immunological behavior as a result of microbial attack. Plant growth-promoting rhizobacteria most commonly beneficial for promoting the plant growth as a result of nutrients uptake by plant and readily available to the nodule formations. Many of the green algae also involved in making the beneficial relationship to the microbes. These are blue-green algae and a host of other beneficial microorganisms. Fungi also show the symbiotic association with different plants mostly in hyphae formation. For example, the chitin-derived lipo-chitooligosaccharides. Transferring the some characters from plants and microbes to the different organisms helpful to establish the relationship among various food chain animals.

The present study aimed to evaluate the influence of light emitting diode (LED) on in vitro rooting of Moringa oleifera Lam shoots. To achieve this, the vitroplants were grown in MS mod 3B basal medium, supplemented with 20 g/l sucrose and without phytohormones, and subjected to white and red LED light for 4 weeks. At the end of the experiment, it was observed that there were significant differences between the LED lights used in terms of the number of roots and the weight of the callus obtained. The white LED gave vitroplants with many roots and reduced callus. Thus, the basic medium MS mod 3B, with 20 g.L-1 sucrose and without phytohormones, and the white LED could be used for a good rooting of M. oleifera in vitro plants.
