Austrobaileya has long served as a model for ancient angiosperm pollen structure. Its pollen germination is relatively rapid and requires < 10 % of the progamic phase. Extensive evidence discussed in this paper suggests pollen germination underwent acceleration early in angiosperm history. More
Grapevines growing in Australiasuffer from high temperatures which have major effects on photosynthesis and transpiration. To learn more, gas exchange was measured in this study over several seasons and then modelled across temperatures from 20 to 45oC and validated with independent data. More
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 other traits, among populations. More
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. More
This paper compiles and discusses all currently available nuclear genome size data for red algae in relation to their most recent taxonomic classification. More
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 abiotic stress. More
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 responds linearly to purified GFP titration. More
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. More
A recent report places AoB PLANTS Handling Editor Kermit Ritland at the center of a commercial breeding programme of paw paw. “This guy Si Brown is so interesting” Kermit comments; “[He] made a cold call to me one day, that is the way venture capitalists work. Si got a degree in Plant Ecology from McGill […] More
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. More
Submergence inhibits photosynthesis by terrestrial wetland plants, but less so in species that possess leaf gas films when submerged. Floodwaters are often supersaturated with dissolved CO2enabling photosynthesis by submerged terrestrial plants, although rates remain well-below those in air. This newly published paper by Timothy D. Colmer, Anders Winkel, and Ole Pedersen reviews this important adaptation that […] More
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 diversity across these mountain ranges. More
