Study Finds ‘Missing Link’ in the Evolutionary History of Carbon-Fixing Protein Rubisco

By | GPC Community, News, Plant Science

Researchers identify a unique version of a photosynthetic enzyme that has been in use for billions of years. A team of scientists has discovered an ancient form of rubisco, the most abundant enzyme on Earth and critical to life as we know it. Found in previously unknown environmental microbes, the newly identified rubisco provides insight into the evolution of the photosynthetic organisms that underlie the planet’s food chains.

Efficient pollen identification

By | News, Plant Science

From pollen forecasting, honey analysis and climate-related changes in plant-pollinator interactions, analysing pollen plays an important role in many areas of research. Microscopy is still the gold standard, but it is very time consuming and requires considerable expertise. Scientists have now developed a method that allows them to efficiently automate the process of pollen analysis.

Plants without cellular recycling systems get creative in the dark

By | ASPB, News, Plant Science

Deprived of sunlight, plants are unable to transform carbon dioxide from the atmosphere into sugars. They are essentially starved of one of their most important building blocks. The plant’s not-so-secret weapon to combat this and other scarcity is autophagy. Similar to recycling, autophagy helps break down damaged or unwanted pieces of a cell, so that building blocks can be used again. New research shows that plants that lack the core components for autophagy have to get creative about recycling nutrients like carbon when they’re left in the dark.

Engineering Drought-Resistant Crops with Crassulacean Acid Metabolism (CAM) Photosynthesis

By | ASPB, News, Plant Science

Drought causes major crop losses in many regions of the world, and climate change threatens to exacerbate the occurrence of drought in temperate as well as arid regions. Researchers used a sophisticated mathematical modelling approach to study the effects of introducing CAM photosynthesis, which is used by plants that are able to thrive in arid conditions, into C3 plants, which tend to thrive only in areas where sunlight intensity and temperatures are moderate and water is plentiful.

Genome duplications as evolutionary adaptation strategy

By | News, Plant Science

Genome duplications play a major role in the development of forms and structures of plant organisms and their changes across long periods of evolution. Biologists made this discovery in their research of the Brassicaceae family. To determine the scope of the different variations over 30 million years, they analysed all 4,000 species of this plant family and investigated at the genus level their morphological diversity with respect to all their characteristic traits.
