Polyploidy, the condition of possessing more than two complete genomes in a cell, has
intrigued biologists for almost a century. Polyploidy is found in many plants and some animal …

In vitro chromosome doubling can be induced by several antimitotic agents. The most
commonly used are colchicine, oryzalin and trifluralin. The process of induced chromosome …

To investigate the impact of manipulating stomatal density, a collection of Arabidopsis
epidermal patterning factor (EPF) mutants with an approximately 16-fold range of stomatal …

Abstract Background and Aims Specific leaf area (SLA), a key element of the 'worldwide leaf
economics spectrum', is the preferred 'soft'plant trait for assessing soil fertility. SLA is a …

Abstract Background and Aims The amount of DNA in an unreplicated gametic chromosome
complement is known as the C-value and is a key biodiversity character of fundamental …

Angiosperms show a remarkable range in genome size (GS), yet most species have small
genomes, despite the frequency of polyploidy and repeat amplification in the ancestries of …

Karyological characteristics are among the traits underpinning the invasion success of
vascular plants. Using 11 049 species, we tested the effects of genome size and ploidy …

The abrupt origin and rapid diversification of the flowering plants during the Cretaceous has
long been considered an “abominable mystery.” While the cause of their high diversity has …

Recent work has made progress in relating the size of stomata to stomatal functioning and,
in particular, the speed of opening and closing and its implications. Calculations of the …

Nearly four decades ago, Roose & Gottlieb (Roose & Gottlieb 1976 Evolution 30, 818–
830.(doi: 10.2307/2407821)) showed that the recently derived allotetraploids Tragopogon …
