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...

Free Paper — Modelling leaf photosynthetic and transpiration temperature-dependent responses in Vitis vinifera cv. Semillon grapevines growing in hot, irrigated vineyard conditions
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...
Free paper — Seed germination and seedling development ecology in world-wide populations of a circumboreal Tertiary relict
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...
Free paper — Genome size in Anthurium evaluated in the context of karyotypes and phenotypes
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 ...
Free paper — Estimates of nuclear DNA content in red algal lineages
This paper compiles and discusses all currently available nuclear genome size data for red algae in relation to their most recent taxonomic classification.
Free paper — Non-symbiotic haemoglobins—What’s happening beyond nitric oxide scavenging?
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...
Free paper — An epifluorescent attachment improves whole-plant digital photography of Arabidopsis thaliana expressing red-shifted green fluorescent protein
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...
Free paper — 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 in this recently published paper provide a sound...
AoB PLANTS Handling Editor involved in an exciting commercial paw paw breeding programme
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...
Free paper — Identification of Stylosanthes guianensis varieties using molecular genetic analysis
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...
Free paper — A perspective on underwater photosynthesis in submerged terrestrial wetland plants
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...
Free paper — Conservation genetics of the rare Pyreneo-Cantabrian endemic Aster pyraneus (Asteraceae)
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...
Free paper — Dividing without centrioles
Innovative MTOCs organize mitotic spindles in bryophytes, the earliest extant lineages of land. Triple staining of γ-tubulin, microtubules, and nuclei here reveal that three types of MTOCs initiate spindles in...
Free—open access paper: Evolutionary development of the plant spore and pollen wall
This article provides an overview of the development and structure of spore and pollen walls in the major plant groups and summarises progress in our understanding of the molecular genetics underpinning spore/pollen...
