This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fruit quality, its postharvest maintenance, and shelf life are critical in crop production and for many crops have been altered by breeding, adjustment of cultural practices and storage conditions as well as application of chemicals such as fungicides. Fruit that do not meet quality standards e.g. due to poor appearance and taste, excessive postharvest deterioration, fungal decay, or the presence of spoilage are unmarketable and cause economic losses to producers, shippers, wholesalers, retailers, and consumers. Strawberry (Fragaria x ananassa) are universally appreciated for their sensory fruit quality attributes but are highly perishable soft fruit with short shelf life. In the last decades, production and marketing requirements for strawberries have shifted towards large scale, centralized production and long-distance shipping and thus requirements for fruit quality have changed towards firm, long shelf life fruit. Breeding has met those demands by developing firm, large fruited, extended shelf life cultivars. Compared to modern cultivars, fruit from older varieties are softer with shorter shelf life but are often perceived as better tasting. The main objective of this dissertation is to increase the understanding of how strawberry (Fragaria x ananassa) fruit quality, shelf life, and susceptibility to fungal decay are genetically controlled and how breeding has altered those traits in the last decades. The specific objectives are: 1) Understand how breeding has reshaped fruit quality and shelf life (Chapter 1). Fruit quality is multi-faceted and relevant to sensory consumer satisfaction e.g. through taste, texture, or appearance, but is also relevant to successful marketing and shipping e.g. through appearance and shelf life. Understanding what caused the actual and perceived differences in fruit quality between old and modern cultivars as well as the genetics that underly those traits is important for plant breeders. Additionally, tools need to be developed to efficiently phenotype and select for those traits (marker-trait association or genomic selection). 2) Assess the current knowledge on the strawberry - Botrytis cinerea pathosystem (Chapter 2). Another critical aspect in fruit quality and shelf life is fungal decay. In strawberry, up to 80% of fruit can be lost under unfavorable conditions, both pre-harvest and postharvest. The main fungal spoilage pathogen in strawberry fruit is Botrytis cinerea, an ubiquitous necrotrophic fungus with broad host range and complex infection strategies. Management of this fungus is currently mainly based on fungicides, but innovative approaches such as biological control or fruit treatments with e.g. edible coatings are being tested. Interestingly, unripe fruit are resistant to the fungus and become increasingly susceptible throughout ripening. Additionally, breeding has been hypothesized to have decreased strawberry susceptibility to B. cinerea, possibly due to correlations with fruit quality, e.g. increased fruit firmness, changes of sugar - acid balance, or anthocyanin concentration, but susceptibility differences between modern and old cultivars have never been proven. 3) Characterize the genetic architecture of strawberry susceptibility to B. cinerea (Chapter 3). To understand what factors influence B. cinerea susceptibility in ripe strawberry fruit, large scale studies of diverse germplasm are necessary to investigate the genetic architecture of fungal disease susceptibility as well as correlation of fruit quality with B. cinerea susceptibility. For this purpose, development of high throughput phenotyping protocols and tools for selection (e.g. genomic selection) are critical as they will facilitate both academic studies and commercial breeding. 4) Characterize adaptation necrotrophic fungal infection strategies to different physiological conditions in fruit via fruit ripening stages (Chapter 4). In order to target studies and breeding for improved resistance of fruit to B. cinerea and necrotrophic fungi in general, it is critical to understand infection strategies of necrotrophic fungi. This information will help what tools fungi use to facilitate successful infections and understanding how strategies change throughout fruit ripening will help to understand the effect of fruit quality (e.g. cell wall fortification, sugar - acid ratio) on both the infection outcome and the adaptation of infection strategies of necrotrophic fungi. Results from this dissertation contribute to a better understanding of factors underlying strawberry fruit quality and interaction with fungal pathogens. Many findings can be integrated into breeding for improved strawberry quality or can be used to guide future studies on fruit quality and fruit-pathogen interaction.

Download or read book Post harvest Pathology written by Dov Prusky and published by Springer Science & Business Media. This book was released on 2009-12-01 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a collection of papers that includes material presented at the 2008 International Congress for Plant Pathology, this text features research right at the leading edge of the field. The latest findings are particularly crucial in their implications for fruit production; an important market sector where in some areas up to 50 per cent of the crop can be lost after harvest. While post-harvest fruit treatments with fungicides are the most effective means to reduce decay, rising concerns about toxicity have led to the development of alternative approaches to disease control, including biological methods, the subject of three chapters of this book. With several new techniques requiring modification of current post-harvest practices, it is more important than ever to stay abreast of the latest information. Other chapters deal with the mechanisms of host fruit and vegetable resistance, fungal pathogenicity factors and their relationship with the host response, and a number of subjects related to disease assessments before harvest as well as their relationship to the postharvest treatment of fruits and vegetables. The book also includes several useful case studies of crops such as kiwifruit and peaches, where different approaches at the pre- and post-harvest levels are combined to good effect. With food production issues gaining an ever higher profile internationally, this text makes an important contribution to the debate.
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.

Available in PDF, EPUB and Kindle. Book excerpt: The world population has been increasing day by day, and demand for food is rising. Despite that, the natural resources are decreasing, and production of food is getting difficult. At the same time, about one-quarter of what is produced never reaches the consumers due to the postharvest losses. Therefore, it is of utmost importance to efficiently handle, store, and utilize produce to be able to feed the world, reduce the use of natural resources, and help to ensure sustainability. At this point, postharvest handling is becoming more important, which is the main determinant of the postharvest losses. Hence, the present book is intended to provide useful and scientific information about postharvest handling of different produce.

Download or read book Advances in Postharvest Pathology of Fruits and Vegetables written by Boqiang Li and published by Frontiers Media SA. This book was released on 2020-01-03 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fruits and vegetables are an important part of a healthy diet. However, one third of fruit and vegetables are lost after harvest every year. Most losses are caused by pathogen (mostly fungi) infections, which lead to postharvest decay. In addition, some postharvest fungal pathogens can produce toxic secondary metabolites (i.e. mycotoxins) during their infecting periods. Mycotoxin contamination may cause serious food safety issues. At present, the use of synthetic fungicides is still the main means to control postharvest diseases. However, the development of resistance in fungal pathogens to fungicides and the growing public concern over the health and environmental risks associated with high levels of pesticides in fruits and vegetables have urged researchers to develop alternative methods of disease control. A deeper understanding of the infecting mechanisms of postharvest pathogens will provide great insight into developing new controlling strategies.

Book excerpt: The book covers the latest development in the biosciences field covering key topics in crop improvement including ‘omic approaches to improving sustainable crop production, advancement in marker technology, strategies in genetic manipulation, crop quality and sustainability and plant microbe interaction detailing on proven technologies to address critical issue for agricultural sustainability which are beneficial for researchers and students. The book also includes aspects of preserving crops after harvest as this is a key factor in promoting sustainable crop quality in terms of addressing waste, choosing the appropriate packaging and moving crops through the food and industrial supply chain. An important strategy to overcome the challenges in providing food for the world population in a sustainable manner is through concerted efforts by crop scientists to embrace new technologies in increasing yield, quality and improving food safety while minimizing adverse environmental impact of the agricultural activities. Most of the proven molecular and genetic technologies in crop science have been tested and verified in model plants such as Arabidopsis and tomato. The technologies, when deployed on various plant species of importance for human nutrition and industrial applications, including cereals, vegetables, fruits, herbs, fibre and oil crops, face many challenges, not only due to their longer life cycle but many other physiological and environmental factors affecting yield and quality of plant products. Furthermore, major impacts on crop production due to catastrophic diseases and global climate change needs urgent and innovative solutions. Therefore a systematic approach, employing various leading-edge technologies that enable the functional elucidation of key pathway genes via ‘omics tools, genome wide association with desired phenotypes and development of cost effective and practicable molecular tools for selection, is vital. The International Conference on Crop Improvement was held to address these and other pressing issues. This volume summarizes the keynote presentations from the meeting and highlights addition discussions that are critical to crop improvement in a challenging time.
