Download or read book Biotechnology and Ecology of Pollen written by David L. Mulcahy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Recognition of the Forgotten Generation D. L. MULCAHyl Pollen was long believed to serve primarily a single function, that of delivering male gametes to the egge A secondary and generally overlooked value of pollen is that it serves to block the transmission of many defective alleles and gene combinations into the next generation. This latter function comes about simply because pollen tubes carrying defective haploid genotypes frequently fail to complete growth through the entire length of the style. However, the beneficial consequences of this pollen selection are diluted by the fact that the same deleterious genotypes are often transmitted through the egg at strictly mendelian frequencies (Khush, 1973). Gene expression in the pollen might thus at least appear to be a phenomenon of trivial consequence. Indeed, Heslop-Harrison (1979) rightly termed the gametophytic portion of the angiosperm life cycle, the "forgotten generation." This neglect, however, came about despite subtle but constant indications that pollen is the site of intense gene activity and selection. For example, Mok and Peloquin (1975) demonstrated that relatively heterozygous diploid pollen shows heterotic characteristics whereas relatively homozygous diploid pOllen does not. This was proof positive that genes are expressed (that is, transcribed and translated) in the pollen. 1 Department of Botany, University of Massachusetts Amherst, MA 01003, USA viii However, the implications for pollen biology of even this recent and well known study were not widely recognized.

Download or read book Applications of Fast Breeding Technologies in Crop Improvement and Functional Genomics Study written by Xingguo Ye and published by Frontiers Media SA. This book was released on 2024-07-30 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the latest ten years, fast breeding technologies have been effectively applied in crop trait modification, gene mapping, and functional genomics study, which include haploid induction based on inducer lines, genome editing mediated by CRISPR/Cas9, and molecular selection based on special markers. By using CRISPR/Cas9, many crop traits such as disease resistance, good quality, early maturity, high grain weight, male sterile, and pre-harvest sprouting tolerance have been modified in a few generations. Particularly, new haploid inducer lines have been created in maize, rice, Arabidopsis, wheat, alfalfa, foxtail millet, tomato, and Brassica oleracea by editing MTL (PLA1/NLD), DMP, and PLD3 genes via CRISPR/Cas9 for largely producing haploid grains directly. Additionally, new types of molecular markers have been developed and used to trace agronomically important traits for easily screening and locating gene position on chromosomes for gene cloning, except for generally employed makers like SSR, SNP, and EST.

Download or read book The Potato Crop written by Hugo Campos and published by Springer Nature. This book was released on 2019-12-03 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.
