This book was released on 2011 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Population growth and climate change pose a serious challenge to food supply. Agriculture is the biggest consumer of freshwater in the world. With widespread water scarcity and expected changes in rainfall patterns, both boosting plant yield using the same amount of water and increasing the survival and yield of crops under drought are top priorites for plant biologists. The understanding of genetic and physiological mechanisms controlling water-use efficiency (WUE) and of plant resistance to drought is, however, still limited. Tomato (Solanum lycopersicum L.) is an excellent genetic model with a rich source of natural variation in its wild relatives. S. pennellii Correll, among them, is adapted to the arid conditions of the Andean region in South America and exhibits a high tolerance to drought and increased WUE, measured as biomass gained per unit of water lost. In this work, a series of crosses and screening steps were done with the aim of introducing some of the genetic determinant(s) of S. pennellii's adaptation to drought into cultivated tomato (miniature cultivar Micro-Tom). Selecting hybrids with delayed wilting, a homozygous line was found which showed delayed wilting upon water deprivation and increased WUE. This novel genotype, named WELL (an acronym for Water Economy Locus in Lycopersicon) exhibited pleiotropic traits, including semi-determinate growth habit, elongated internodes, and more erect, wrinkled leaves. The introgressed segment was mapped to a pericentromeric region of 42 to 54 cM on the long arm of chromosome 1, which comprises the yellow fruit epidermis pigmentation gene. Physiological analyses showed that WELL leaves have lower stomatal conductance than their Micro-Tom counterparts under drought, in spite of a similar or slightly increased stomatal density, implying more closed stomata i.e. an increased stomatal sensitivity to water deprivation in WELL leaves. Recombinant lines with reduced introgressions (1-24 cM) were generated. Their preliminary analysis indicated that some of the pleiotropic traits in WELL were not genetically linked to the delayed wilting phenotype and two of the recombinant lines appeared to have altered growth responses under drought, but this deserves closer examination.

Therefore, more extensive exploration and effective exploitation of plant genetic resources are essential prerequisites for the release of improved cultivars. Accordingly, the remarkable progress in genomics approaches and more recently in sequencing and bioinformatics offers unprecedented opportunities for mining germplasm collections, mapping and cloning loci of interest, identifying novel alleles and deploying them for breeding purposes. This book collects 48 highly interdisciplinary articles describing how genomics improves our capacity to characterize and harness natural and artificially induced variation in order to boost crop productivity and provide consumers with high-quality food. This book will be an invaluable reference for all those interested in managing, mining and harnessing the genetic richness of plant genetic resources.
Download or read book Allele Mining for Genomic Designing of Vegetable Crops written by Chittaranjan Kole and published by CRC Press. This book was released on 2024-06-03 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deliberates on the concept, strategies, tools, and techniques of allele mining in vegetable crops and its application potential in genome elucidation and improvement including studying allele evolution, discovery of superior alleles, discerning new haplotypes, assessment of intra- and interspecific similarity, and studies of gene expression and gene prediction. Available gene pools in global germplasm collections specifically consisting of wild allied species and local landraces for almost all major crops have facilitated allele mining. Development of advanced genomic techniques including PCR-based allele priming and Eco-TILLING based allele mining are being widely used now for mining superior alleles. Allele's discovery has become more relevant now for employing molecular breeding to develop designed crop varieties matching consumer needs and with genome plasticity to adapt the climate change scenarios. All these concepts and strategies along with precise success stories are presented in the chapters dedicated to the major vegetable crops. The first book on the novel strategy of allele mining in vegetable crops for precise breeding Presents genomic strategies for mining superior alleles underlying agronomic traits from genomic resources Depicts case studies of PCR-based allele priming and Eco-TILLING based allele mining Elaborates on gene discovery and gene prediction in major vegetable crops This book will be useful to the students and faculties in various plant science disciplines including genetics, genomics, molecular breeding, agronomy, and bioinformatics; the scientists in seed industries; and, the policymakers and funding agencies interested in crop improvement.

Download or read book Molecular and Metabolic Mechanisms Associated with Fleshy Fruit Quality written by Ana M. Fortes and published by Frontiers Media SA. This book was released on 2017-09-08 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fleshy Fruits are a late acquisition of plant evolution. In addition of protecting the seeds, these specialized organs unique to plants were developed to promote seed dispersal via the contribution of frugivorous animals. Fruit development and ripening is a complex process and understanding the underlying genetic and molecular program is a very active field of research. Part of the ripening process is directed to build up quality traits such as color, texture and aroma that make the fruit attractive and palatable. As fruit consumers, humans have developed a time long interaction with fruits which contributed to make the fruit ripening attributes conform our needs and preferences. This issue of Frontiers in Plant Science is intended to cover the most recent advances in our understanding of different aspects of fleshy fruit biology, including the genetic, molecular and metabolic mechanisms associated to each of the fruit quality traits. It is also of prime importance to consider the effects of environmental cues, cultural practices and postharvest methods, and to decipher the mechanism by which they impact fruit quality traits. Most of our knowledge of fleshy fruit development, ripening and quality traits comes from work done in a reduced number of species that are not only of economic importance but can also benefit from a number of genetic and genomic tools available to their specific research communities. For instance, working with tomato and grape offers several advantages since the genome sequences of these two fleshy fruit species have been deciphered and a wide range of biological and genetic resources have been developed. Ripening mutants are available for tomato which constitutes the main model system for fruit functional genomics. In addition, tomato is used as a reference species for climacteric fruit which ripening is controlled by the phytohormone ethylene. Likewise, grape is a reference species for non-climacteric fruit even though no single master switches controlling ripening initiation have been uncovered yet. In the last period, the genome sequence of an increased number of fruit crop species became available which creates a suitable situation for research communities around crops to get organized and information to be shared through public repositories. On the other hand, the availability of genome-wide expression profiling technologies has enabled an easier study of global transcriptional changes in fruit species where the sequenced genome is not yet available. In this issue authors will present recent progress including original data as well as authoritative reviews on our understanding of fleshy fruit biology focusing on tomato and grape as model species.
