Essential features of chromosomes in all eukaryotes including plants and animals are Replication, Segregation, gene expression and inheritance. PubMedGoogle Scholar. This finding provides a likely explanation of why F. vesca came to quickly dominate gene expression among resident subgenomes. Today the resulting subgenomes continue to behave as separate blueprints interpreted simultaneously to define the assembly and function of a common complex structure. It has extremely small berries, fine flavor, surprisingly little of the usual strawberry aroma, but a refreshing acidity. All rights reserved. BMC Plant Biol. The DNA found in strawberry cells can be extracted using common, everyday materials. These findings are of great interest, as few resistance genes have been characterized in strawberry, and they may represent new tools for molecular marker development that will allow breeders to coalesce multiple resistance genes into a single genetic background. Fern (Ophioglossum reticulatum) is a homosporous fern containing the highest number of chromosomes than plants, animals, or fungus.
