Ebook "Aluminum stress adaptation in plants (Signaling and communication in plants, Volume 24)" is an overview of our current understanding of aluminium toxicity and tolerance in plants. It covers all relevant aspects from molecular and cellular biology, to genetic approaches, root biology and plant physiology. The contribution of arbuscular mycorrhizal fungi to alleviating aluminium toxicity is also discussed. Over 40% of total agricultural land resources are acidic in nature, with aluminium being the major toxicant.

Bacteria are ubiquitous in nature. Based on their role bacteria may be grouped as beneficial, spoilage causing and pathogens. The saprophytic group, involved in causing the spoilage of milk and milk products, produce various kinds of surfactants to utilize the milk components. Synthetic surfactants dominate in the market especially in detergent formulations and considered as non-biodegradable and toxic. Biosurfactants are surface metabolites produced by bacteria and fungi having very different chemical structures and properties.

This study was conducted to evaluate the effect of crude and different solvent extract of Leaf of Lantana camara, an aggressive invasive weed against plant pathogenic fungi Colletorichum falcatum causing Red rot of sugarcane disease under in vitro conditions. Aqueous crude extract and solvent extracts such as extracts Methanol, Ethyl acetate, Chloroform were tested at 2mg/mL, 4mg/mL and 8mg/mL concentrations. Results revealed that all the 3 solvent extracts showed significant inhibition at higher concentrations when compared to the Standard Fluconazole (15μg/ml).

Nanotechnology is an interdisciplinary having significant role in modern science. Myconanotechnology is an emerging field, where fungi are being used for the synthesis of nanoparticles with desirable size and shape. Fungi have an added advantage over bacteria as well as actinomycetes, as fungi are excellent secretors of proteins leads to a higher yield of nanoparticles which are highly stable, cost-effective, eco-friendly and non-toxic.

Bio control agents (Trichoderma viride, Pseudomonas fluorescens) and various fungitoxicants were tested for their efficacy in controlling the Fusarium wilt of chickpea caused by Fusarium oxysporum f. sp. ciceri in vitro and in vivo. In vivo conditions soil inoculated with Fusarium oxysporum f. sp. ciceri was conducted to compare the efficacy of different treatments viz. seed treatment with bio-control agents and fungitoxicants in the management of chickpea wilt.

Climate change is a key factor for emerging food and feed safety issues all over the world. Aflatoxins are potent mycotoxins that cause developmental and immune system suppression, cancer, and death. The expected impact on the occurrence of mycotoxins in food and feed is of great concern. Among mycotoxins, aflatoxins have acute and chronic toxicity that cause suppression of immune system and even cancer. Hence, its concentration in agricultural food, feed and their commodities is regulated worldwide. Fungi Aspergillus is responsible for aflatoxin contamination in maize grains.

Trichoderma species, a class of plant beneficial fungi, may provide opportunistic symbionts to induce plant tolerance to abiotic stresses. Here, we determined the possible mechanisms responsible for the indole acetic acid (IAA) and 1-aminocyclopropane-1-carboxylate-deaminase (ACC-deaminase) producing strain of Trichoderma longibrachiatum T6 (TL-6) in promoting wheat (Triticum aestivum L.) growth and enhancing plant tolerance to NaCl stress.

Herbicide is the most important input in the modern agriculture. The use of herbicides has been expanding more rapidly than that of other pesticides. The injudicious application of herbicides in agriculture causes the contamination of the soil with toxic chemicals and become harmful to the microorganisms, plant, wildlife and man. In view of the above a field experiment was conducted during rabi season of 2015-16 with the groundnut variety TAG-24 with twenty four treatment combination in three replications.

Banded leaf and Sheath blight of maize caused by Rhizoctonia solani f.sp. Sasakii [teleomorph: Thanatephorus cucumeris] is of worldwide occurrence and is known to cause substantial yield losses. It is a major production constraint in high yielding varieties under intensive maize production systems. The pathogen has a very wide host range and exhibits considerable pathogenic and molecular variability. Due to non-availability of highly resistant cultivars, the management of banded leaf and sheath blight primarily relies on chemical control.

Corynespora leaf fall (CLF) disease of rubber incited by Corynespora cassiicola is listed as a fourth most serious leaf disease of rubber in South East Asia. As the rubber is a tree crop it grows up to 60 – 70 feet height, management of this disease is not easy and it involves more price tag. The use of effective and economical management strategies is plays a vital role in efficient disease management in rubber plantations. To develop a tool to integrated disease management approach, tested different bio-agents, plant extracts and fungicides against Corynespora cassiicola.

Mycotoxins are secondary metabolites of filamentous fungi that occur naturally in food and feed. The presence of these compounds in the food chain is of high concern for human health due to their properties to induce severe toxicity effects at low dose levels. The contamination of fruits with mycotoxins has not only caused health hazards but also resulted in economic losses, especially for exporting countries.
