Ecological traits of the circumboreal plant Viburnum opulus were examined here to improve understanding of the variation of populations occurring in the same biome but on different continents. Seedling development/emergence is shown to be highly similar but some degree of variation was present in o

Little is known about the genome of Anthurium other than chromosome observations, which frequently indicate supernumerary (“B”) chromosomes. New genome size estimates for 34 species and nine cultivars presented here provide insights into genome organization and evolution in this very large genus.

The evidence presented here suggests non-symbiotic hemoglobins affect hormone responses by scavenging NO. Auxin, jasmonic acid, salicylic acid, ethylene and abscisic acid have altered responses when hemoglobins are expressed. Non-symbiotic hemoglobin is a factor during plant development, biotic and

This paper reports that filter cubes made with machine-vision dichroic filters and illuminated with a royal blue light emitting diode can be used to produce an epifluorescent digital camera attachment that improves whole organism green fluorescent protein (GFP) photography. Mean pixel intensity res

The genome size and organization of the important medicinal plant Catharanthus roseus is shown to correspond to 1C = 0.76 pg (~738 Mbps) and 2n=16 chromosomes. The data in this recently published paper provide a sound basis for future studies including cytogenetic mapping, genomics and breeding.

Molecular genetic diversity and population structure analysis were used to clarify the controversial botanical classification of Stylosanthes guianensis. In this paper, the accessions were clustered in nine groups, each of which was mainly composed of only one of the four botanical varieties.

Nathalie Escaravage, Jocelyne Cambecèdes, Gérard Largier and André Pornon present here the genetic structure of the endangered endemic species, Aster pyrenaeus. Only 14 populations remain in the Pyrenees and the Cantabrian Mounts. The study provides new insights into the pattern of plant genetic di
