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.
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.
Aloe vera is a well-known plant species from the genus Aloe used throughout the globe in wide range of products from creams and soaps to drinks and over-the-counter products. The genus Aloe has been used in traditional medicine for centuries, and approximately 20% of the species are used locally in the regions they grow.
Rice (Oryza sativa L) is the world’s most widely used cereal for human consumption and the second most produced in the world after maize. However, rice production is seriously threatened by rice blast, a fungal disease that has been reported in more than 80 countries on all continents, including the growing areas of almost all rice-producing regions in Spain (Andalusia, Extremadura, Catalonia, Valencia, etc.).
Governments are not using the latest mapping technology to report key environmental data about tropical forests to the UN, say researchers.
Tree roots commonly associate with fungi to exchange nutrients and improve their adaptation to changes in their environment. However, the biological processes at work in this mutually beneficial relationship (namely ectomycorrhizae) have not yet been fully explored. Now, researcher have demonstrated for the first time that the establishment of the symbiotic relationship between the model tree poplar and an ectomycorrhizal fungus is controlled by epigenetics.
Can the deathbed rally of a few dying cells save the rest of the body? New evidence from plants. The “deathbed rally,” the “last hurrah” — it’s not unheard of for living things to mysteriously perk up in the moments before death. It turns out that plants do it too, at least at the cellular level.
Researchers ahave recently discovered a new species of Fabaceae. The new species was named Astragalus bashanense.
The tropics hold most of the planet’s biodiversity. In order to preserve this fragile and valuable asset, many individuals and communities need to get involved and be well informed. However, tropical ecology and conservation sciences are still often affected by colonialistic and discriminatory practices, which can hamper nature conservation success. An international research team from leading universities in tropical research has now proposed how researchers from the Global South, which consists of nations historically damaged by colonialism, could better promote solutions for a sustainable development.
