Pulses have played a major role in human diet and are considered a rich source of proteins. But, the major constraints in achieving the yield of pulses are the occurrences of various diseases and pests. Hence, there is a need to understand major fungal pathogens and their management strategies for sustainable agriculture. The major pulse crops in India and other Asian countries are bengal gram, pigeon pea, black gram, green gram, lentil and peas, which are attacked by several pathogens that cause considerable crop damage. Bengal gram is affected mainly by wilt (Fusarium oxysporum f. sp. ciceri), blight (Mycosphaerella pinodes) and rust (Uromyces ciceris-arietini). The main diseases of pigeon pea are wilt (Fusarium oxysporum) and Phytophtora stem blight (Phytophthora drechsleri f. sp. cajani). Powdery mildew (Erysiphe polygoni) and rust (Uromyces vicia-fabae) are the most important diseases affecting the production of pea. This volume offers details like symptoms, distribution, pathogens associated, predisposing factors and epidemiology, sources of resistance and holistic management of diseases with particular reference to those of economic importance. Several minor diseases of lentil, green gram and of black gram are discussed with their detailed and updated information. This volume provides pooled information regarding the management of major fungal phytopathogens affecting pulses.

The existence of life at high temperatures is quiet fascinating. At elevated temperatures, only microorganisms are capable of growth and survival. A variety of microbes survive and grow at such high temperatures. Many thermophilic microbial genera have been isolated from man-made (washing machines, factory effluents, waste streams and acid mine effluents) and natural (volcanic areas, geothermal areas, terrestrial hot springs, submarine hydrothermal vents, geothermally heated oil reserves and oil wells, sun-heated litter and soils/sediments) thermal habitats throughout the world. Both culture-dependent and culture-independent approaches have been employed for understanding the diversity of microbes in hot environments. These organisms not only tolerate such high temperatures but also usually require these for their growth and survival. They are known as thermophiles/thermophilic microbes, which include a wide variety of prokaryotes (Bacteria and Archaea) as well as eukaryotes (Fungi, Algae, Protozoa). Interest in their diversity, ecology, and physiology has increased enormously during the past few decades as indicated by the deliberations in international conferences on extremophiles and thermophiles every alternate year. The Phylogenetic relationship of the known microorganisms indicates the presence of thermophilic microorganisms at the position close to the Last Universal Common Ancestor (LUCA). It is widely accepted that metal-reducing microorganisms have a large impact on the geochemistry of subsurface environments through the cycling of metals and organic matter, and thereby affect water quality and taste. Furthermore, metal-reducing micro-organisms have potential applications in bioremediation, mineral leaching and energy generation processes and are of evolutionary interest as metal reduction is considered to be a very ancient form of respiration. Protein characterization surprisingly indicated that possible additional functionality and alternate site promiscuity could contribute to the diverse biochemical abilities of the bacteria, especially with respect to microbe-metal interactions. Thermophilic bacteria are also able to reduce a wide spectrum of other metals including Mn (IV), Cr (VI), U (VI), Tc (VII), Co (III), Mo (VI), Au (I, III), and Hg (II) which can be used for immobilization of toxic metals/radionuclides, e.g. for the bioremediation of hot waste water of disposal sites of radioactive wastes having temperature range favorable for thermophiles for a long period of time. The main sources of CO in hot environments inhabited by anaerobic thermophiles are volcanic exhalations and thermal degradation of organic matter. A number of phylogenetically diverse anaerobic prokaryotes, both Bacteria and Archaea, are known to metabolize CO. CO transformation may be coupled to methanogenesis, acetogenesis, hydrogenogenesis, sulfate or ferric iron reduction. The key enzyme of anaerobic CO utilization, the Ni-containing CO dehydrogenase, is synthesized in hydrogenogens as an enzyme complex with the energy-converting hydrogenase. The genomic analysis shows this enzymatic complex to be encoded by a single gene cluster. Themophilic moulds and bacteria have been extensively studied in plant biomass bioconversion processes, as sources of industrial enzymes and as gene donors for the heterologous expression of thermostable enzymes. In the development of third generation biofuels such as bioethanol, thermophilic fungal and bacterial enzymes are of particular interest. The entire genomes of several thermophilic bacteria and archaea have already been sequenced. The analysis of the genomic data provided resources for novel and useful proteins and enzymes. The entire genomic data have also provided specific feature of microbes and important information on the evolution of thermophilic microorganisms. In some thermophilic archaea, multiple types of chaperonins have been identified. The chaperonins have been found to change according to the environmental conditions, suggesting that the mechanism for maintaining correct structure of thermostable proteins in the thermophilic archaea is regulated by changing chaperonine molecules. These organisms have evolved several structural and chemical adaptations, which allow them to survive and grow at elevated temperatures. Thermostable enzymes play an important role in the biosynthesis of fine chemicals. They are generally more robust against the conditions of industrial biocatalysis utilized by the industry, which can be solvent based or at elevated temperatures. Many non-natural industrially interesting substrates are often not soluble under aqueous conditions and at ambient temperatures. The thermophilic Archaea are a good source of these enzymes, which have been cloned and over-expressed in Escherichia coli. These include alcohol dehydrogenases for chiral alcohol production, aminoacylases for optically pure amino acids and amino acid analogues, transaminases for chiral amine production and gamma lactamases for chiral gamma lactam building blocks which are subsequently incorporated into carbocyclic nucleotides. Considerable interest has been generated in the mechanism that nature utilizes to increase the stability of enzymes found in thermophilic and hyperthermophilic species. A comparative approach has been used to carry out a detailed study of specific enzymes from a range of organisms in order to understand acquired stability at a structural level. A directed or site-specific mutagenesis approach has been used for stabilizing mesophilic proteins. The specific mutations have been introduced by looking at the most primitive forms of life, which are thought to have evolved in a thermophilic environment. The book is aimed at bringing together scattered up-to-date information on various aspects of thermophiles such as the diversity of thermophiles and viruses of thermophiles, their potential roles in pollution control and bioremediation, composting and microb

Bacteria were the first life on Earth. But what do we really know about them? In this captivating, science-driven book, you'll learn everything you need to know about these often misunderstood-and incredibly interesting-microbes. In this engagingly written and scientifically rigorous book, author and scientist Ludger Wess introduces an eclectic collection of impressive, useful, weird, and dangerous bacterial species. Wess reveals everything he knows about bacteria, including their ability to survive almost anywhere, to "sleep" for millions of years before becoming active again, to maintain their own immune systems (a discovery that has led to medical breakthroughs for humans), and to-hypothetically-live on other planets. In part two, Wess moves on to his curious compendium of bacterial species, presenting fifty fascinating portraits grouped by useful categories: bacteria that are record holders, extreme-habitat dwellers, unusual consumers, people-helpers, and people-harmers. Beautiful black-and-white illustrations accompany each portrait. At the end of this engrossing read, Wess recognizes how much we still don't know about bacteria. But by starting here, we can come closer to understanding the first life on Earth.

Plants are endowed with innate immune system, which acts as a surveillance system against possible attack by pathogens. Plant innate immune systems have high potential to fight against viral, bacterial, oomycete and fungal pathogens and protect the crop plants against wide range of diseases. However, the innate immune system is a sleeping system in unstressed healthy plants. Fast and strong activation of the plant immune responses aids the host plants to win the war against the pathogens. Plant hormone signaling systems including salicylate (SA), jasmonate (JA), ethylene (ET), abscisic acid (ABA), auxins, cytokinins, gibberellins and brassinosteroids signaling systems play a key role in activation of the sleeping immune systems. Suppression or induction of specific hormone signaling systems may result in disease development or disease resistance. Specific signaling pathway has to be activated to confer resistance against specific pathogen in a particular host. Two forms of induced resistance, systemic acquired resistance (SAR) and induced systemic resistance (ISR), have been recognized based on the induction of specific hormone signaling systems. Specific hormone signaling system determines the outcome of plant-pathogen interactions, culminating in disease development or disease resistance. Susceptibility or resistance against a particular pathogen is determined by the action of the signaling network. The disease outcome is often determined by complex network of interactions among multiple hormone signaling pathways. Manipulation of the complex hormone signaling systems and fine tuning the hormone signaling events would help in management of various crop diseases. The purpose of the book is to critically examine the potential methods to manipulate the multiple plant hormone signaling systems to aid the host plants to win the battle against pathogens.

Marine fungi play a major role in marine and mangrove ecosystems.
