Local and Indigenous communities warn of a significant decrease in the abundance of wild edible plants and mushrooms that negatively impacts their nutrition and food security, from local to global scales.
In new research, scientists used bioinformatics and deep sequencing to identify soil viruses and better understand their roles in the Earth. Most of these viruses infect bacteria, and are thus thought to play an important part in maintaining microbial populations.
The carnivorous Venus flytrap can be anaesthetised with ether. Some surprising parallels to anaesthesia in humans emerge.
Research team shows potential for sustainable land use in Madagascar the most important country for vanilla production – the fragrant ingredient that is a favourite flavour for ice cream, cakes and cookies.
A study has conducted a comprehensive survey of nearly 200 potentially harmful alien plant species that could have a detrimental impact upon agriculture, forestry and biodiversity in Ghana once they enter the country.
Cell division ensures growth or renewal and is thus vital for all organisms. However, the process differs somewhat in animals, bacteria, fungi, plants, and algae. Until now, little was known about how cell division occurs in algae. Researchers have used confocal laser scanning microscopy (CLSM) to capture the very first high-resolution three-dimensional images of cell division in live cells of the microalga Volvox carteri, and have identified new cellular structures involved in the process.
Seven to nine percent of all vascular plant species occurring in Europe are globally threatened. The researchers combined Red Lists of endangered plant species in Europe with data on their global distribution. It helps assess the overall level of threat to plant species and thus supports the basis of international nature conservation activities.
We typically think of plants strutting their best stuff aboveground: showy flowers, fragrant blossoms, and unique shapes abound. But their development belowground is equally magical. In a new study, a team of international scientists, dug deep to better understand one of the most extraordinary root systems in the world.
Wildfires are devastating, but they can also bring new life by clearing existing vegetation and allowing new plants to spring up. Many plants in fire-prone areas actually require exposure to fire for seeds to germinate. In the past decade, scientists have discovered an ancient receptor protein that can detect molecules called karrikins in smoke from burnt plant material. The “smoke detector” protein, called KAI2, initiates molecular signals that speed up germination of seeds.
Whether Guard Cells (GCs) carry out photosynthesis has been debated for decades. Earlier studies suggested that guard cell chloroplasts (GCCs) cannot fix CO2 but later studies argued otherwise. Until recently, it has remained controversial whether GCCs and/or GC photosynthesis play a direct role in stomatal movements.
