Photograph by Ron Oldfield, Macquarie University, See http://dx.doi.org/10.1093/aob/mcs295 The image shows sporophytes and calyptras of Funaria hygrometrica, a water moss (photograph by Ron Oldfield, Macquarie University). The calyptra is a gametophytic tissue that covers the tip of the elongating sporophyte. A young sporophyte with an intact calyptra appears in the lower left corner, whilst other […]
Genetic model organisms have revolutionized science, and with rapid advances in technology there is significant potential to launch more plant species towards model status. However, these new model organisms have to be carefully selected.
A paper in AoB PLANTS describes new methods for real-time monitoring of trace gases such as ethylene, nitric oxide and ethanol which play an important role in many areas of biology.
Celastrus paniculatus, "the intellect tree", is a climbing shrub with medicinal properties found throughout India. And it's under threat.
Teasels are an important species for wildlife, but they don't like salt. Will they survive?
Although micropropagation is a common method these days, much of the science behind regeneration of whole plants from tiny specks of plant tissue remains uncertain.
How useful is environmentally-friendly green roof technology in hostile climates?
Considered by some to be the Mount Everest of crop genomes, the challenging wheat genome is close to being scaled. An international team has produced a draft of wheat's DNA sequence, one that identifies many of its genes and has made possible the identification of thousands of potential genetic changes that could improve this key […]
You might think the answer is "very carefully", but in the case of Opuntia fragilis, it turns out to be "not at all". Considering its aversion to reproduction, one wonders how the brittle prickly pear manages to continue the species? The fragility of its pads provides its survival mechanism. The pads break off easily, and this […]

Salt marshes have been disintegrating and dying over the past two decades along the U.S. Eastern seaboard and other highly developed coastlines, without anyone fully understanding why. A new paper reports that nutrients—such as nitrogen and phosphorus from septic and sewer systems and lawn fertilizers—can cause salt-marsh loss. http://goo.gl/7OeFI #onGplus Google+: Reshared 2 times Google+: View […]
The European Commission says clearing land in order to plant biofuel crops can often cancel out the environmental benefits of biofuel. In some cases forests are chopped down. The EU is putting a cap of 5% on the food-based biofuel allowed in the renewable energy used in transport. #onGplus Embedded Link EU acts to counter biofuel […]
