18 Jan 2018 The condition of possessing more than two complete genomes in a cell has intrigued biologists almost a century. Many plant species including flowering plants are polyploids, and we know that it has a significant role in the evolution and crop improvement. It is well tolerated in many groups of eukaryotes.
Full-text (PDF) | All crop plants are polyploid and some genomes have been duplicated more recently than others. Advancements in cytogenetic and molecular tools, including high-density genetic mapping, fl orescent in situ hybridization, and genome and EST sequencing, have enabled new insights into
Mountain Horticultural Crops Research and Extension Center, North Carolina State University,. 455 Research Drive, Fletcher, North plant breeding programs. WHAT IS POLYPLOIDY AND HOW . Considering the profound importance of polyploidy in plant evolution, it is under- standable that there was considerable
Polyploid formation is often accompanied with loss of duplicated chromatin, changes in gene expression, novel epistatic interactions, and endosperm effects. All of these factors need be considered in a genome-wide context for optimizing marker assisted selection and crop plant improvement. Please view the pdf by using
7 Sep 2006 ation, extrapolation of model plant functional genomics may be limited by paralog subfunctionalization because gene function in model species may not correctly predict gene function in particular crop plants. The Role of Polyploidy in Crop Improvement. For more than 60 yr, polyploidy has been con-.

16 Dec 2015 Full-text (PDF) | Main conclusion: This article provides an up-to-date review concerning from basic issues of polyploidy to aspects regarding the relevance and role of both natural and artificial polyploids in plant breeding programs. Polyploidy is a major force in the evolution of both wild and
15 May 2013 This chapter seeks to illuminate some of these studies and explain the applications and implications of polyploidy in plant breeding and other . Meiotic aberrations related to spindle formation, spindle function and cytokinesis have been implicated in this process (Ramsey and Schemske, 1998).
