New hypothesis proposed on why some seeds are hard

Hard seeds are prevented from germinating by a water-impermeable seed coat, and for many years this has been considered to be a dormancy mechanism. Scientists from Kew, the University of Bergen and the University of Sheffield ...

RIKEN BioResource Center to provide seeds of model cereal plant

Seeds of the model cereal plant Brachypodium distachyon are now available at the RIKEN BioResource Center (BRC) in Japan, the second bioresource facility to provide seeds of this important model plant to the international ...

Why red algae never colonized dry land

The first red alga genome has just been sequenced by an international team coordinated by CNRS and UPMC at the Station Biologique de Roscoff (Brittany), notably involving researchers from CEA-Genoscope, the universities of ...

Updating classifications to reflect monophyly

Improving DNA amplification from problematic plants

The polymerase chain reaction (PCR) is a common technique used to amplify, or copy, pieces of DNA. Amplified DNA is then used in genetic analyses for everything from medicine to forensics. In plant research, PCR is a vital ...
