Hybrid plants, like corn, grow bigger and better than their parents because many of their genes for photosynthesis and starch metabolism are more active during the day, report researchers in the ...
Variation and Evolution in Plants and Microorganisms: Toward a New Synthesis 50 Years After Stebbins
In 1950, G. Ledyard Stebbins devoted two chapters of his book Variation and Evolution in Plants (Columbia Univ. Press, New York) to polyploidy, one on occurrence and nature and one on distribution and ...
One chromosome from the mother, one chromosome from the father: For us humans and the vast majority of animal species, having a double set of ...
For animals, an extra chromosome can result in major problems, but plants are another matter. Many plants can survive an extra copy of their entire genome (polyploidy), and this process often results ...
A research team has elucidated the role of polyploidy in the evolution and breeding of vegetable crops, leveraging advanced sequencing technologies to dissect the genetic and epigenetic nuances of ...

Whole genome duplication (WGD) happens in all kingdoms of life. It is most common in plants, but also occurs in some of the most aggressive cancers. After WGD, the cell has extra genomes and is called ...
WHEN a cell divides to produce two daughter cells having the same genetical properties as itself, the nucleus resolves itself into a definite number of structures, the chromosomes. These, splitting ...
