Chromosome evolution is a fundamental aspect of evolutionary biology. The evolution of
chromosome size, structure and shape, number, and the change in DNA composition …

Most of the present knowledge about cell organization and function is based on molecular
and genetic methods as well as cytological investigations. While electron microscopy allows …

How do separate sexes originate and evolve? Plants provide many opportunities to address
this question as they have diverse mating systems and separate sexes (dioecy) that evolved …

Cannabis sativa–derived tetrahydrocannabinol (THC) production is increasing very fast
worldwide. C. sativa is a dioecious plant with XY Chromosomes, and only females (XX) are …

Plant sex chromosomes can be vastly different from those of the few historical animal model
organisms from which most of our understanding of sex chromosome evolution is derived …

The transfer of genetic material from the mitochondria and plastid to the nucleus gives rise to
nuclear integrants of mitochondrial DNA (NUMTs) and nuclear integrants of plastid DNA …

When sex chromosomes stop recombining, they start to accumulate differences. The sex-
limited chromosome (Y or W) especially is expected to degenerate via the loss of nucleotide …

Seabuckthorn (Hippophae rhamnoides) is a dioecious shrub commonly used in the
pharmaceutical, cosmetic, and environmental industry as a source of oil, minerals and …

Background The cytogenomic study of repetitive regions is fundamental for the
understanding of morphofunctional mechanisms and genome evolution. Passiflora edulis a …

Abstract Background and Aims Dioecious species with well-established sex chromosomes
