BACKGROUND AND AIMS Intraspecific ploidy-level variation is an important aspect of a species' genetic make-up, which may lend insight into its evolutionary history and future potential. The present study explores this phenomenon in a group of eastern Asian Cardamine species. METHODS Plant material was sampled from 59 localities in Japan and Korea, which were used in karyological (chromosome c...
Brachypodium distachyon (L.) P. Beauv. (2n = 2x = 10) is a small annual grass species where the existence of three different cytotypes (10, 20, and 30 chromosomes) has long been regarded as a case of autopolyploid series with x = 5. However, it has been demonstrated that the cytotypes assumed to be polyploids represent two separate Brachypodium species recently named as Brachypodium stacei (2n...
The basal monocot genus Acorus comprises essential oil-producing plants widely used in traditional medicine various countries, including India. calamus sensu lato is a polyploid complex where the oil composition, to some extent, depends on ploidy level. literature recognizes diploids (in temperate Asia and North America), triploids (Asian origin, naturalized elsewhere) tetraploids (temperate tr...
