Differential lineage-specific amplification of transposable elements is responsible for genome size variation in Gossypium.

Abstract excerpt

The DNA content of eukaryotic nuclei (C-value) varies approximately 200,000-fold, but there is only a approximately 20-fold variation in the number of protein-coding genes. Hence, most C-value variation is ascribed to the repetitive fraction, although little is known about the evolutionary dynamics of the specific components that lead to genome size variation. To understand the modes and mechanisms that underlie...
