Anyone who has taken a long road trip or bike ride has used a product of the spurge plant family — rubber. The spurge family, or Euphorbiaceae, includes economically valuable plants like the rubber tree, castor oil plant, poinsettia and cassava. Newly identified fossils found in Argentina suggest that a group of spurges took a trip of their own tens of millions of years ago. Driven by climatic changes and land movements over millennia, a group of spurges relocated thousands of miles from ancient South America to Australia, Asia and parts of Africa.

Plant roots have their own thermometer to measure the temperature of the soil around them and they adjust their growth accordingly. Through extensive experiments, researchers were able to demonstrate that roots have their own temperature sensing and response system. In a new study theyalso provide a new explanation for how roots themselves detect and react to higher temperatures. The results could help develop new approaches for plant breeding.

Using a newly available genome sequence of grass pea (Lathyrus sativus L.) a research team has identified key biochemical steps that lead to the production of the neurotoxin β-L-ODAP (ODAP).  

Plants use photosynthesis to produce oxygen, nutrients and bioenergy. But this complex biochemical process is inefficient, with only a fraction of the sun’s energy actually being utilized in photosynthesis. Researchers want to change this in order to help increase the yield of cultivated crops. A research team has now discovered that the outer envelope membrane of chloroplasts could play a key role in this process.
