Insert Tongue Here – flower arrows guide fly tongues | Not Exactly Rocket Science | Discover Magazine
The iris is pollinated by the accurately named “long-proboscid fly”, whose tongue is twice as long as its body. It hovers over the flower and aims for the centre, driving its tongue deep into the stem to reach the pool of nectar at the bottom. As it drinks, its head pushes against the flower’s male organs, which deposit a dollop of pollen. When the fly leaves, it carries this payload to another iris. The flies and the flowers are intimate partners of evolution. The long tongues and stems have been perfectly aligned to give one partner a drink and the other a flying sexual aide.
All of this depends on the white arrows. When Dennis Hansen from the University of Kwazulu-Natal painted over the markings, the fly could no longer find the flower’s centre. The arrows are like a sign that says, “Insert tongue here”.
Largest-ever Map of Interactions of Plant Proteins Produced
Known as an "interactome," the new Arabidopsis network map defines 6,205 protein-to-protein Arabidopsis interactions involving 2,774 individual proteins. By itself, this map doubles the volume of data on protein interactions in plants that is currently available.

Patrick Schnable gives Capitol Hill seminar on the future of our food
Schnable highlighted the value of next generation sequencing technologies in linking genes to crop traits resulting in ultimate improvements in yield, disease and pest resistance, and nutrient utilization. He sees traditional breeding and genetic engineering as complementary approaches in meeting this goal. He stressed that U.S. involvement in this type of agricultural research is essential.
Talking Plants: International Botanical Congress in Melbourne all a twitter
Half way through the International Botanical Congress in Melbourne it's time to draw breath. The pace has been cracking, particularly with hands on Twitter, eyes on the speaker and mind on running the Congress.
Some background first. The International Botanical Congress is held every six years and attracts botanists from around the world to discuss the latest developments in plant science. The previous congress was held in Vienna, Austria, in 2005, and the next will be held in China in 2017.
