The effect of polyploidy and hybridization on the evolution of floral colour in Nicotiana (Solanaceae).
Speciation in angiosperms can be accompanied by changes in floral colour that may influence pollinator preference and reproductive isolation. This study investigates whether changes in floral colour can accompany polyploid ...
Microsatellites and petal morphology reveal new patterns of admixture in Orchis hybrid zones
The genetic structure of hybrid zones provides insight into the potential for gene flow to occur between plant taxa. Four closely related European orchid species (Orchis anthropophora, O. militaris, O. purpurea, and O. ...
