Cytogenetic characterization and genome size of the medicinal plant Catharanthus roseus (L.) G. Don

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 provide a sound basis for future studies including cytogenetic mapping, genomics and breeding

An epifluorescent attachment improves whole-plant digital photography of Arabidopsis thaliana expressing red-shifted green fluorescent protein

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 responds linearly to purified GFP titration
