When plants attack: parasitic plants use ethylene as a host invasion signal

By | JSPB, News, Plant Health, Plant Science

To develop a successful parasitic relationship, parasitic plants form a specialized structure, the haustorium which attaches to and invades the host plant. The formation of haustoria is regulated by signal molecules derived from the host plant and allows the parasitic plant to absorb water, nutrients, and small materials from the host plant. Now, researchers find that the plant hormone ethylene mediates the invasion of hosts by parasitic plants

Repairing the photosynthetic enzyme Rubisco

By | News, Plant Science

The enzyme Rubisco catalyzes the assimilation of CO2 from the atmosphere into organic matter. This is the central step in photosynthesis that generates sugar molecules for the production of essentially all biomass. Despite its pivotal role, Rubisco works relatively slowly and is easily inhibited by sugar products. By improving the function of Rubisco researchers hope to be able to boost the process of photosynthesis. The goal is to address the growing global demand for food and reduce the current greenhouse gas-induced climate change.

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.
