Rhizosphere microorganisms

Ebook "Iron nutrition in plants and rhizospheric microorganisms" provides comprehensive reviews on topics of plant-iron nutrition that are being addressed by different laboratories around the world. As one can see, the area of plant-iron nutrition is highly interdisciplinary, involving scientists of various fields of knowledge. Plant biologists are needed to characterize iron translocation throughout the plant following root iron uptake and to examine the regulation of iron-stimulated activities that influence crop yield and quality.

The rhizosphere microorganisms can form beneficial, pathogenic, or neutral relationships. These relationships can promote plant growth and productivity. Among them, a number of Variovorax isolates from the rhizosphere were isolated. Bacteria Variovorax strain C6d (AB552893) was isolated from the non axenic culture of Chlorella spp., C6.

In the present study, microalgal biomass (Anabeana circinalis and Scenedesmus quadricauda) was used as biofertilizer in cucumber cultivation. The response of cucumber growth characters to microalgal biofertilizer was evaluated. Moreover, rhizosphere microbial diversity and community composition of cucumber was analyzed through 16S rRNA high-throughput Illumina sequencing data. The results showed that microalgal biomass as biofertilizer significantly promoted height, number of leaves and flower buds, and stem diameter of cucumber. The application of a high concentration of S.

The rhizosphere is part of the soil surrounding the plant roots or being influenced by the plant roots. The exudates released from roots make it a site for complex biochemical activity. Microorganisms make up one of the dynamic parts of this rhizosphere, and affect soil and plant growth by various means.

In the present study collected twenty (20) direct sown paddy rhizosphere soil samples from four districts of Andhra Pradesh and recorded their geographical position of collected soil samples. From that thirty two (32) Zinc Solubilizing Bacteria (ZnSB) isolated by using zinc phosphate [Zn3(PO4)2] as a insoluble source of zinc in the trismineral salts media. Zinc solubilizing isolates coded based on their soil sample collected geographical position, recorded the morphological, cultural characteristics of ZnSB.
