“How much a plant accumulates GABA when it is stressed determines how much it applies the brake pedal to reduce the pore opening the following morning, and water loss that day - like a stress memory of the day before.” – Dr. Bo Xu.

Plant drought tolerance relates to pore openings

Science Notes: Molecule associated with relaxation controls the size of pores and water loss

Reading Time: 2 minutes A team of Australian and German researchers has discovered a novel pathway that plants can use to save water and improve their drought tolerance. The research published recently in Nature Communications shows that the molecule GABA (gamma-aminobutyric acid), most commonly associated with relaxation in animals, can control the size of the pores on plant leaves […] Read more

In the world’s largest study of so-called “jumping genes,” the researchers traced two particular jumping genes.

Australian scientists find species-jumping genes more common than thought

Cross-species gene transfers, even between plants and animals have occurred frequently

Reading Time: 2 minutes University of Adelaide, Australia, scientists have shown that widespread transfer of genes between species has radically changed the genomes of today’s mammals and been an important driver of evolution. In the world’s largest study of so-called “jumping genes,” the researchers traced two particular jumping genes across 759 species of plants, animals and fungi. These jumping […] Read more
