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.

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.

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. 

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.

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 expressed. Non-symbiotic hemoglobin is a factor during plant development, biotic and abiotic stress.

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.
