Density-dependent processes influencing the evolutionary dynamics of dispersal: a functional analysis of seed dispersal in Arabidopsis thaliana (Brassicaceae).

We conducted a functional analysis of seed dispersal and its plasticity in response to density in Arabidopsis thaliana by growing morphologically diverse ecotypes under high and low density and measuring seed dispersion patterns under controlled conditions. Maternal plant architectural traits such as height and branching, and fruit traits such as dehiscence and silique length influenced various...

Molecular evolution of phytochromes in Cardamine nipponica (Brassicaceae) suggests the involvement of PHYE in local adaptation.

Given that plants are sessile organisms, traits involved in adapting to local environments and/or in monitoring the surrounding environment, such as having photoreceptors, are significant targets of natural selection in plant evolution. To assess the intraspecific adaptive evolution of photoreceptors, we investigated sequence variations in four phytochrome genes (PHYA-C and PHYE) of Cardamine n...

Lectotypification of names of Himalayan Brassicaceae taxa currently placed in the genus Cardamine

Lectotypes of twenty-eight names of taxa currently recognized or synonymized in Cardamine are designated as part of the work on the account of the genus for the Pan-Himalayan Flora. Among them, the previous first-step lectotypification of the name Cardaminecalthifolia is finalized. In cases when specimen images are available online, stable identifiers for specimens, other permanent links, or li...

Origin of the disjunct tetraploid Cardamine amporitana (Brassicaceae) assessed with nuclear and chloroplast DNA sequence data.

Seventy-four nucleotide sequences from the ITS regions of nuclear ribosomal DNA and 76 from the trnL-trnF spacer of chloroplast DNA were used to address the origin of tetraploid Cardamine amporitana, the conspecifity of central Italian and northeastern Spanish populations, and the possible cause for such geographic disjunction. Because of the complex lineage relationships in Cardamine, the samp...
