Polyploidy: From Evolution to New Plant Development Polyploidy: From Evolution to New Plant Development©
INTRODUCTION Polyploidy is an intriguing phenomenon in plants that has provided an important pathway for evolution and speciation. Although the first polyploid was discovered over a century ago, the genetic and evolutionary implications of polyploidy are still being elucidated (Bennett, 2004; Soltis et al., 2003). On a more practical level, there are many opportunities for utilizing polyploidy ...
متن کاملPolyploidy
Polyploidy is defined as an increase in genome DNA content. Throughout the plant and animal kingdoms specific cell types become polyploid as part of their differentiation programs. When this occurs in subsets of tissues within an organism it is termed somatic polyploidy, because it is distinct from the increase in ploidy that is inherited through the germline and present in every cell type of t...
متن کامل-ATPase from Oat Seedlings
Acidification of endomembrane compartments by the vacuolar-type H 1 -ATPase (V-ATPase) is central to many cellular processes in eukaryotes, including osmoregulation and protein sorting. The V-ATPase complex consists of a peripheral sector (V 1 ) and a membrane integral sector (V o ); however, it is unclear how the multimeric enzyme is assembled. A 64-kD polypeptide that had copurified with oat ...

متن کاملEndoreplication: polyploidy with purpose.
A great many cell types are necessary for the myriad capabilities of complex, multicellular organisms. One interesting aspect of this diversity of cell type is that many cells in diploid organisms are polyploid. This is called endopolyploidy and arises from cell cycles that are often characterized as "variant," but in fact are widespread throughout nature. Endopolyploidy is essential for normal...
