This book was released on 2002 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminum (Al) toxicity is one of the major constraints for agriculture on acid soils, which occupy large regions of the word's agricultural area. At the low pH values associated with these soils (pH 4 -5). Al+3 is solubilized into the soil solution and is toxic to plants, dramatically inhibiting root growth and crop yield. Plant breeding approaches have been used to develop Al tolerant crop genotypes for over 50 years. In order to further improve crop Al tolerance, researchers are now investigating the molecular and physiological mechanisms underlying crop Al tolerance, with the ultimate goal of isolating major Al tolerance genes. Sorghum is an important cereal crop species that exhibits extraordinary levels of tolerance to abiotic stresses such as Al toxicity and drought. Yet, almost nothing is known about the genetics and physiology of sorghum Al tolerance, hence this was the focus of the thesis research described here. A detailed molecular genetic characterization of the mechanisms of Al tolerance in sorghum was conducted in two sources of sorghum Al tolerance, SC283 and SC566. SC283 was found to harbor a single major Al tolerance gene (Alt sb), which exhibited partial dominance in this study. Alt sb was subsequently mapped to a chromosomal location that was apparently not conserved in relation to the location of known Al tolerance genes in wheat and barley. Additional studies indicated that Al tolerance in SC566 is also controlled by the Alt sb gene. The results are discussed with regards to the possible conservation of Al tolerance genes across species in the Poaceae. The physiological studies of Al tolerance were performed with Al tolerant (ATF10B) and sensitive (ATF8B) near isogenic lines derived from SC283. These studies suggested that Alt sb encodes a tolerance mechanism that acts by excluding Al from sensitive sites in the root tip via and Al-activated root citrate exudation. Al tolerance in ATF10B appears to be inducible by Al, in that Al tolerance increased as the roots were exposed to Al for longer time periods. The thesis is concluded with a description of future research that will focus on the isolation of Alt sb by positional cloning.

Book Synopsis Biotechnologies of Crop Improvement, Volume 3 by : Satbir Singh Gosal
Download or read book Biotechnologies of Crop Improvement, Volume 3 written by Satbir Singh Gosal and published by Springer. This book was released on 2018-08-09 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past 15 years, cellular and molecular approaches have emerged as valuable adjuncts to supplement and complement conventional breeding methods for a wide variety of crop plants. Biotechnology increasingly plays a role in the creation, conservation, characterization and utilization of genetic variability for germplasm enhancement. For instance, anther/microspore culture, somaclonal variation, embryo culture and somatic hybridization are being exploited for obtaining incremental improvement in the existing cultivars. In addition, genes that confer insect- and disease-resistance, abiotic stress tolerance, herbicide tolerance and quality traits have been isolated and re-introduced into otherwise sensitive or susceptible species by a variety of transgenic techniques. Together these transformative methodologies grant access to a greater repertoire of genetic diversity as the gene(s) may come from viruses, bacteria, fungi, insects, animals, human beings, unrelated plants or even be artificially derived. Remarkable achievements have been made in the production, characterization, field evaluation and commercialization of transgenic crop varieties worldwide. Likewise, significant advances have been made towards increasing crop yields, improving nutritional quality, enabling crops to be raised under adverse conditions and developing resistance to pests and diseases for sustaining global food and nutritional security. The overarching purpose of this 3-volume work is to summarize the history of crop improvement from a technological perspective but to do so with a forward outlook on further advancement and adaptability to a changing world. Our carefully chosen “case studies of important plant crops” intend to serve a diverse spectrum of audience looking for the right tools to tackle complicated local and global issues.

This book was released on 2024-02-13 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Research Topic is part of the article collection series - Multi-omics and Computational Biology in Horticultural Plants: From Genotype to Phenotype. Horticultural plants play an important role for humans by providing herbal medicines, beverages, vegetables, fruits, and ornamentals. High-throughput technologies have revolutionised the time scale and power of detecting insights into physiological changes and biological mechanisms in plants. All sequencing data and tools have helped us better understand the evolutionary histories of horticultural plants and provide genotype and phenotype resources for molecular studies on economically important traits. The integration of these -omics technologies (e.g., genomics, transcriptomics, proteomics, metabolomics, lipidomics, ionomics, and redoxomics) is currently at the forefront of plant research. The genomes of horticultural plants are highly diverse and complex, often with a high degree of heterozygosity and polyploidy. Novel computational methods need to be developed to take advantage of state-of-the-art genomic technologies. As a result, the mining of multi-omics data and the development of new computational biology approaches for the reliable and efficient analysis of plant traits is necessary.

Book Synopsis Water Stress and Crop Plants by : Parvaiz Ahmad
Download or read book Water Stress and Crop Plants written by Parvaiz Ahmad and published by John Wiley & Sons. This book was released on 2016-06-08 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants are subjected to a variety of abiotic stresses such as drought, temperature, salinity, air pollution, heavy metals, UV radiations, etc. To survive under these harsh conditions plants are equipped with different resistance mechanisms which vary from species to species. Due to the environmental fluctuations agricultural and horticultural crops are often exposed to different environmental stresses leading to decreased yield and problems in the growth and development of the crops. Drought stress has been found to decrease the yield to an alarming rate of some important crops throughout the globe. During last few decades, lots of physiological and molecular works have been conducted under water stress in crop plants. Water Stress and Crop Plants: A Sustainable Approach presents an up-to-date in-depth coverage of drought and flooding stress in plants, including the types, causes and consequences on plant growth and development. It discusses the physiobiochemical, molecular and omic approaches, and responses of crop plants towards water stress. Topics include nutritional stress, oxidative stress, hormonal regulation, transgenic approaches, mitigation of water stress, approaches to sustainability, and modern tools and techniques to alleviate the water stress on crop yields. This practical book offers pragmatic guidance for scientists and researchers in plant biology, and agribusinesses and biotechnology companies dealing with agronomy and environment, to mitigate the negative effects of stress and improve yield under stress. The broad coverage also makes this a valuable guide enabling students to understand the physiological, biochemical, and molecular mechanisms of environmental stress in plants.
