Growing edible mushrooms alongside trees can produce a valuable food source for millions of people while capturing carbon, mitigating the impact of climate change, a new study has found.

Researchers have developed the first-ever microneedle-based drug delivery technique for plants. The method can be used to precisely deliver controlled amounts of agrochemicals to specific plant tissues for research purposes. When applied in the field, it could be used in precision agriculture to improve crop quality and disease management.
New research finds almost 4000 Australian plant species have not been photographed before in the wild, which may lead to their extinction.
The DNA sequence of a gene in wheat responsible for resisting a devastating virus has been discovered, providing vital clues for managing more resistant crops and maintaining a healthy food supply.
Photosynthesis is the process whereby plants turn sunlight into the energy (sugars) that they need to survive and grow. For most plants, this happens in the leaves, which contain chlorophyll; a green pigment that is essential for photosynthesis as it absorbs light. However, some plants have evolved unconventional ways of performing photosynthesis.
A research team has discovered the mechanisms by which the seed decides to remain in «hibernation» or to trigger its germination depending on the outside temperature.
Seed germination depends on light in many plants. But not always: Aethionema arabicum, a plant adapted to challenging environmental conditions, does it its own way. Here, the phytochromes, the receptors for red and far-red light, play an unexpected role in seed germination and time this process to the optimal season. These findings are a compelling example of the evolutionary rewiring of signaling modules that help plants adapt to their habitats.
Plant Genetic Resources underpin not only the future of agriculture and food security, but are increasingly being re-evaluated to address issues such as climate adaptation, nutrition and the wider bio-economy. This week a prominent ‘perspective’ paper provides an excellent overview and explanation of the international agreements that govern use of Plant Genetic Resources (PGR) as well as best practices for complying with the agreements.
An international team of scientists found that the right number of copies of a specific group of genes can stimulate longer root growth, enabling wheat plants to pull water from deeper supplies. The resulting plants have more biomass and produce higher grain yield,
New research from the Swedish University of Agricultural Sciences has found that a plant’s natural ability to store seeds in soil, a method for preserving seeds in unfavourable conditions, is not as useful as once thought.
