Researchers at Leipzig University and the German Centre for Integrative Biodiversity Research (iDiv) have compiled the world's most comprehensive list of known plant species. It contains 1,315,562 names of vascular plants, thus extending the number by some 70,000 - equivalent to about 20%. The researchers have also succeeded in clarifying 181,000 hitherto unclear species names. The data set has now been published in Scientific Data. This marks the culmination of ten years of intensive research work.
Princeton researchers Shan He, Martin Jonikas, and colleagues have discovered how Rubisco holoenzymes assemble to form the fluid-like matrix of the algal pyrenoid, an organelle that mediates the incorporation of carbon dioxide into sugars. The study detailing the group's findings was published November 23, 2020 in the journal Nature Plants.
Princeton University researchers have discovered that assembly of the algal pyrenoid, a structure that mediates the incorporation of carbon dioxide into sugars, is guided by the presence of a particular protein sequence, or motif. The study describing this breakthrough, by researchers Moritz Meyer, Martin Jonikas, and colleagues, appeared November 11, 2020 in the open-access journal Science Advances.
With new insights into how the genetic tool CRISPR - which allows direct editing of our genes - evolved and adapted, we are now one step closer to understanding the basis of the constant struggle for survival that takes place in nature. The results can be used in future biotechnologies.
Australian researchers have identified a protein that could protect the kidneys from 'bystander' damage caused by cancer therapies. The 'cell survival protein', called BCL-XL, was required in laboratory models to keep kidney cells alive and functioning during exposure to chemotherapy or radiotherapy. Kidney damage is a common side effect of these widely used cancer therapies, and the discovery has shed light on how this damage occurs at the molecular level.
Bread wheat can grow in highly diverse regional environments. An important reason for its great genetic variety is the cross-hybridization with many chromosome fragments from wild grasses. This is shown by the genome sequences of 10 wheat varieties from four continents, which an international consortium including researchers from the University of Zurich has now decoded.
On a near daily basis, the internet spews out numerous tips and tricks for exercise motivation. Now we can add smell to the long and growing list. A research team led by a scientist at the University of California, Riverside, has found olfaction--or smell--may play an important role in motivating mammals to engage in voluntary exercise. Performed in lab mice, the study may open up new areas of research and have relevance for humans.
Living at low gravity affects cells at the genetic level, according to a study of worms in space.
Using data collected from a number of different resources, a multidisciplinary team is reporting discovery of a common thread that drives this damage: mitochondrial dysfunction. The researchers used a systems approach to look at widespread alterations affecting biological function. The findings are reported November 25 in the journal Cell.
University of Cincinnati researchers have discovered new clues into why some people with head and neck cancer respond to immunotherapy, while others don't.
