Book Description
Insect-Plant Interactions and Induced Plant Defence Chair: John A. Pickett, 1999 This book examines the sophisticated mechanisms that plants use to defend themselves against attack by insects and pathogens, focusing on the networks of plant signalling pathways that underlie these defences. In response to herbivory, plants release a complex blend of as many as 100 volatile chemicals, known as semiochemicals ('sign chemicals'). These act as an airborne SOS signal, revealing the presence of the herbivore to the predators and parasitoids that are its natural enemies. Plants also have endogenous defence mechanisms that can be induced in response to pathogens, and separate chapters deal with systemic acquired resistance, phytoalexins, and the interacting pathways in pathogen and pest resistance. The book discusses underlying biochemical mechanisms by which plant stress leads to the biosynthesis of chemical signals from pools of secondary metabolite precursors, or even from the primary metabolism source. Finally, consideration is given to the possibilities for exploiting these signalling pathways by plant molecular genetics. The use of plant signals and their analogues to switch on defence pathways in crop plants is covered in depth. Bringing together contributions from entomologists, chemical ecologists, molecular biologists and plant physiologists this book is truly interdisciplinary, and will be essential reading for anyone with an interest in agricultural pest control.

Book Description
This Reference Work is devoted to plant secondary metabolites and their evolutionary adaptation to different hosts and pests. Secondary metabolites play an important biological role in plants’ defence against herbivores, abiotic stresses and pathogens, and they also attract beneficial organisms such as pollinators. In this work, readers will find a comprehensive review of the phytochemical diversity, modification and adaptation of secondary metabolites, and the consequences of their co-evolution with plant parasites, pollinators, and herbivores. Chapters from expert contributors are organised into twelve sections that collate the current knowledge in intra-/inter-specific diversity in plant secondary metabolites, changes in secondary metabolites during plants’ adaptation to different environmental conditions, and co-evolution of host-parasite metabolites. Among the twelve themed parts, readers will also discover expert analysis on the genetics and chemical ecology evolution of secondary metabolites, and particular attention is also given to allelochemicals, bioactive molecules in plant defence and the evolution of sensory perception in vertebrates. This reference work will appeal to students, researchers and professionals interested in the field of plant pathology, plant breeding, biotechnology, agriculture and phytochemistry.

Book Description
"Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well." "Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production." "This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Book Description
Drought and herbivory are two stresses that threaten productivity and survival of plants. While plant responses to either drought or herbivory are well studied, the responses of plants to concurrent drought and herbivory are unclear. This dissertation investigates the impact of water availability on plant-insect interactions using chemical ecology, plant physiology, molecular biology, and ecology approaches. We discovered that drought stress enhances plant resistance against insect herbivores and reduces plant tolerance against defoliation. In addition to its negative impact on plant tolerance, drought stress also reduces the number of insect natural enemies and other arthropods on plants. The reduction in arthropod number was found to benefit certain insect herbivores by reducing negative species interactions such as competition and predation. We hypothesized that the reduction in arthropod number on drought-stressed plants are partly associated with changes in plant volatile emission and found that the detrimental effects of drought on natural enemy attraction was associated with changes in herbivore-induced plant volatile (HIPV) emissions. Using current knowledge on ecology of drought-plant-insect interactions, we discussed the implications of water availability on plant anti-herbivore defenses and the integration of water and pest management in crop production around the world. Furthermore, we discover the ability of insect herbivores to induce drought-like response for their own benefit. We identify a hydrogen peroxide-producing salivary protein (glucose oxidase, GOX) in caterpillar Helicoverpa zea that triggers stomatal closure in plants. Stomatal closures were further linked to inhibition of important defense related HIPVs, such as (Z)-3-hexenyl acetate and (Z)-3-hexenol, which is similar to HIPV changes caused by drought. The findings discover an herbivore adaptation that utilize drought-like responses of plants for their own benefits and show the links between stomatal behavior and HIPV emission. This is the first study that utilizes CRISPR-Cas9 mutagenesis to study salivary protein function of insect herbivores and showed that organisms other than microbes can modulate behavior of stomata. As changes in water availability and pest continue to threaten plants in both natural and agricultural systems under climate changes, this dissertation contributes to a better understanding of the impacts of drought stress on plant-insect interactions from molecular, organismal, to populational levels. Additionally, we highlight the ability of insect herbivores to induce drought-like responses of plants, such as stomatal closure, for their own benefit, which is a novel strategy that have not been reported to date. We further demonstrate that stomata are important parts of plant responses to herbivores, in addition to its roles in responses to abiotic stresses and pathogen attack. However, significant knowledge gap exists in stomatal functions in plant-insect interactions, we are certain that the findings in this dissertation will incite further research and lead to a better understanding of stomatal functions in plant responses to their environment.
