Efficacy of root-associated fungi and PGPR on the growth of Pisum sativum (cv. Arkil) and reproduction of the root-knot nematode Meloidogyne incognita
No full textThe effects of root-associated fungi (Aspergillus awamori and Glomus mosseae) and plant growth promoting rhizobacteria (PGPR) (Pseudomonas putida, Pseudomonas alcaligenes and Paenibacillus polymyxa) were studied alone and in combination in glasshouse experiments on the growth of pea, enzyme activity (peroxidase and catalase) and reproduction of root-knot nematode Meloidogyne incognita. Application of A. awamori, G. mosseae and PGPR caused a significant increase in pea growth and enzyme activities of both nematode inoculated and uninoculated plants. A. awamori was more effective in reducing galling and improving the growth of nematode inoculated plants than P. alcaligenes or P. polymyxa. The greatest increase in growth, enzyme activities of nematodeinoculated plants and reduction in galling and nematode multiplication was observed when A. awamori was used with P. putida or G. mosseae as compared to the other combinations tested. Percentage root colonization was higher when AM fungus inoculated plants were treated with P. putida both in presence and absence of nematode.

Arbuscular Mycorrhizal Fungi and Opportunistic Fungi: Efficient Root Symbionts for the Management of Plant Parasitic Nematodes
No full textArbuscular mycorrhizal fungi (AMF) and opportunistic fungi (OP) are the important groups of efficient root symbionts, which play a key role in the management of plant parasitic nematodes (PPN). The AM fungi have the ability to increase plant growth by nutrient uptake and water absorption while opportunistic fungi produced some biologically active metabolites. In recent years, these root symbionts have been widely used for management of plant diseases caused by PPN in various crops because they not only have the capability to modify the quality and abundance of rhizosphere microflora but also alter the overall rhizosphere microbial activity. Beside this, these symbionts may also induce changes in the host root exudation pattern. Concerning the high cost of inorganic fertilizers and the negative effect of chemical pestides on the environment and human health, the mycorrhizal and opportunistic fungi are used as a potential tool for the management of plant diseases caused by plant parasitic nematodes. This review presents a cumulative effect of PPN on plant health and the interaction takes place between the PPN, AM and opportunistic fungi on various host systems. Recent cost effective technologies for mass propagation of these efficient symbionts at commercial scale for the field application are also discussed.

No full textIn recent years, nanobiotechnology has emerged as an elementary division of modern science and a noval epoch in the fields of material science and is receiving global attention due to its ample applications. Various physical, chemical, and biological methods have been employed to synthesize nanomaterials. Biological systems such as bacteria, fungi, actinomycetes, yeasts, viruses, and plants have been reported to synthesize various metal and metal oxide nanoparticles. Among these, biosynthesis of nanoparticles from plants seems to be a very effective method in developing a rapid, clean, nontoxic, and eco-friendly technology. The use of plant biomass or extracts for the biosynthesis of novel metal nanoparticles (silver, gold, platinum, and palladium) would be more significant if the nanoparticles are synthesized extracellularly and in a controlled manner according to their dispersity of shape and size. Owing to the rich biodiversity of plants, their potential use toward the synthesis of these nobel metal nanoparticles is yet to be explored. The aim of this review is to provide the recent trends involved in the phytosynthesis of nobel metal nanoparticles in the past decade.

Status and Distribution Study for Different Forms of Potassium in the Soils of Nignoti Village of Indore District of Western Madhya Pradesh

No full textNot AvailableThe aim of this study was to assess the comparative efficacy of summer and monsoon season on the
rhizospheric microbial population (actinomycetes, bacteria, fungi) and various soil enzymatic activities (acid and
alkaline phosphatases, dehydrogenase and phytase) in three horticultural plant species of arid region. In general, microbial population, enzymatic activities and microbial biomass carbon (MBC) were higher in rhizosphere as compared to non rhizosphere soil. Monsoon season represents optimum conditions for proliferation of microbial population and thereby, increase in various enzymatic activities, which in turn was responsible for mobilization of unavailable nutrients for plants. During monsoon season rhizosphere soil of Z. mauritiana maintain 7.3% more moisture followed by E. officinalis (7.1%) and P. dactylifera (4.8%) as compared to non-rhizosphere soil. In general, an overall increase in acid phosphatase (65%), alkaline phosphatase (25%), phytase (30%), dehydrogenase (24%) and MBC (21%) was reported in rhizosphere as compared to non-rhizosphere soil.Not Availabl
