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...
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...
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...
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 ...
This paper compiles and discusses all currently available nuclear genome size data for red algae in relation to their most recent taxonomic classification.
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...
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...
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...
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...
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...
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...
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...
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...
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...
