Plant DNA speaks English, identifies new species

23.03.2012
The important changes to the way scientists name new plants that took effect on 1 January 2012 included the fall of the so-called Latin requirement - a stipulation that descriptions or diagnoses of new species had to be in Latin.

The new rules make it possible to take full advantage of an ongoing revolution in how botanists and mycologists verify that a particular species is indeed new to science: Many studies now routinely include the sequencing of short DNA regions that will amplify easily, even when the DNA comes from old specimens.

Such "barcoding" sequences can be used to confirm a suspected new species as long as related species that already have a scientific name are also being sequenced for the same DNA stretch.

There is no standard Latin vocabulary for describing DNA barcoding, yet in English, there is.

In an article in the open access journal PhytoKeys, botanists Natalia Filipowicz (Medical University of Gdañsk), Michael Nee (New York Botanical Garden), and Susanne Renner (University of Munich), now provide the first English-language diagnosis of a new species that relies exclusively on DNA data.

Their publication of a new species in the Solanaceae genus Brunfelsia also includes a traditional morphology-based description and pictures of the plant, but the researchers trust that "molecular diagnoses" will become a standard feature in future taxon descriptions.

The DNA sequences generated for the study have all been deposited in the public database GenBank, enabling other researchers to make use of them.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
