Book Summary:

Novel Aspects of Insect-Plant Interactions Edited by Pedro Barbosa and Deborah K. Letourneau Focusing on three trophic levels, this study widens the current understanding of the ecological interactions between plants, herbivores, and their parasitoids and predators. Emphasized are the mediating effects of plant-derived allelochemicals on those interactions. The book also covers microorganisms as mediators of intertrophic and intratrophic interactions; theory and mechanisms: plant effects via allelochemicals on the third trophic level; and key roles of plant allelochemicals in survival strategies of herbivores. 1988 (0 471-83276-6) 362 pp. Plant-Animal Interactions Evolutionary Ecology in Tropical and Temperate Regions Edited by Peter W.

Book Summary:

Soil-borne microorganisms can have significant effects on aboveground interactions between plants and other organisms. For example, association with some non-pathogenic soil microbes stimulates plants and modify volatile emissions, defense capability, nutritional quality and host gene expression. Likewise, detrimental microorganisms like some plant viruses, can also change plant phenotype in ways that influence transmission. As a result, microbe-plant associations may indirectly modify the interactions among plants, herbivorous insects and parasitoids. While the relevance of microorganisms on the ecology of plant mediated interactions has been widely studied, research that integrates ecological and molecular approaches involved in these multi-trophic interactions are still limited. The general goal of this research is to understand how microbial associations influences plant-pathogen and plant-insect interactions in soybean. To achieve this goal, I use a combination of chemical analysis, gene transcriptomics and insect behavior linked with state-of-the-art data mining techniques. We examined how two species of beneficial rhizobacteriathe plant growth promoter rhizobacteria (PGPR) species Delftia acidovorans, which lives in the rhizosphere in close association with root surfaces, and the nitrogen-fixing Bradyrhizobium japonicuminfluence the interactions of soybean plants (Glycine max cultivar Williams 82) with the herbivorous beetle Epilachna varivestis, which vectors an economically important pathogen of cultivated soybean, Bean pod mottle virus (BPMV) and with the parasitoid wasp Pediobius foveolatus. In a multi-factorial experiment, we characterized the volatile organic compounds (VOC), the primary and secondary leaf metabolites and the transcriptome produced by soybean plants in the presence/absence of the two rhizobacteria and with or without infection by BPMV. Our results indicate that BPMV infection and inoculation with beneficial rhizobacteria cause dramatic changes in metabolites and genes related with plant nutrition and defense, with significant consequences for soybean interactions with an important herbivore and virus vector.

Book Summary:

There are many non-pathogenic viruses that are maintained in a persistent lifestyle in plants. Plant persistent viruses are widespread, replicating in their hosts for many generations. The roles of plant persistent viruses have not been studied thoroughly, but their very long-term relationships with their hosts, and their high level of vertical transmission imply beneficial interactions. So far, Endornaviridae is the only family with a single-stranded RNA genome, containing one large open reading frame. Bell pepper endornavirus (BPEV), Hot pepper endornavirus, Capsicum frutescens endornavirus 1 (CFEV 1) have been identified from peppers. Peppers are native to Central and South America, and as domesticated plants human selection accelerated their evolution. Using a collection of 97 different peppers the evolution of pepper persistent viruses was studied. The evolution of endornaviruses in different peppers was investigated using two fragments from the viral helicase (Hel) and RNA dependent RNA polymerase (RdRp) domains. In addition, by using single nucleotide polymorphisms the pepper host populations and phylogenies were analyzed. The endornaviruses phylogeny was correlated with its Capsicum species host. In this study BPEV was limited to C. annuum species, and the RdRp and Hel phylogenies identified two clades that correlated with the host pungency. No C. annuum infected with CFEV 1 was found in this study, but the CFEV 1 RdRp fragment was recovered from C.chinense, C. frutescens, and C.bacccutum and C. pubescens.Partitiviridae is the most common persistent virus family in wild plants. Jalapeo and Hungarian Wax peppers (Capsicum annuum) have been reported with Pepper cryptic virus 1 (PCV 1) and Pepper cryptic virus 2 (PCV 2), respectively. Both viruses belong to the genus Deltapartitivirus from Partitiviridae family. The evolution of PCV 1 and PCV 2 was investigated using the RdRp and coat protein of both viruses. Both viruses were detected in cultivated and wild peppers. It is shown that these viruses have a remarkably slow evolution rate in comparison with acute RNA viruses. This might be correlated with the strong purifying selection related to the lifestyle of theses viruses, or the replication strategies in double stranded RNA viruses, that use a stamping machine mode of replication. Finally, some potential beneficial effects of persistent virus were examined. In wild plants partitivirus infection decreased the likelihood of acute virus infection. I compared the effect of odor cues from PCV 1 infected (J+) and virus free (J-) Jalapeo pepper on the aphid Myzus periscae, a common vector of acute plant viruses. Pairwise preference experiments showed a stark contrast to insect-plant interactions in acute virus infections: virus infected plants deterred aphids. The acute plant virus Cucumber mosaic virus (CMV) manipulates its host's volatile emission to attract aphid vectors and facilitate its transmission. Volatiles of J+ and J- CMV infected plants were more attractive to aphids than J+ and J- mock inoculated plants. However, in pairwise preference between J+ CMV- and J- CMV-infected plants, aphids preferred the J- CMV volatile blend. Also, aphid fecundity on J+ and J- plants was measured as an indicator for the effect of PCV 1 on host quality for aphids. Aphid reproduction on J+ plants was more than two fold lower than J- plants. This study demonstrates a beneficial relationship between PCV 1 and Jalapeo plants by protecting the plants from the vector of acute viruses. In addition, the effect of PCV 1 on the Jalapeo's developmental growth was tested by measuring the average time required for seed germination, emergence of first true leaf, first open flower and dried biomass of plants. PCV 1 showed no significant effect on the developmental growth of Jalapeo plants.

Book Summary:

The history of pathogens and vectors, unique symptoms of diseases and economic importance of important viral diseases have been dealt with in the introductory chapter of this book. While highlighting the role of arthropods, nematodes, and fungi; other agents of the spread of plant pathogens have also been included. Important aspects of insect vectors with direct bearing on transmission, i.e. vector identification, biology, feeding apparatus, and mechanism of spread including control of pathogens through vectors are covered comprehensively. As aphids and other hemipterous insects are major insect vectors, the book stresses on this order. There is a focus on the transmission of determinants under different categories of the transmission mechanism. The transmission determinant paradigm comprising coat protein and helper component has been expounded with recent cases. A brief description of new diseases at least one from each genus of plant viruses has been included in this compendium to elucidate the interaction of vector and virus. Phytoplasmal etiology of pathogens has been detailed separately on account of their importance. The transmission of plant viruses through insects with biting and chewing type of mouth parts has been discussed in detail as separate chapter. The latest research in the field of mites, nematodes, and fungi as vectors of plant viruses has been included. How the phytotoxemia is different from other crop disorders, has been critically explained with support from suitable and common examples of crop disorders. The book also highlights the effects of plant viruses on their vectors. An account of classification of plant viruses has also been given for better understanding of subject matter. Likewise, the information on the electron microscope along with its use has been included so as to define the procedure of examining sub-microscopic entities. The latest developments in the management of plant pathogens through vector management have been discussed with special reference to the use of biotechnology, crop protection, and plant resistance. The book will be of value to the teachers and to researchers. It will also be useful for extension workers in managing crop disorders. Students and researchers of entomology, plant pathology, plant protection and virology disciplines will obtain the latest in the field, through this book.
