The current world population of 7.8 billion is predicted to reach 10 billion by 2057. Future access to affordable and healthy food will be challenging, with malnutrition already affecting one in three people worldwide. Two new papers recognized that global crop production systems need to expand their outputs sustainably to feed this rapidly growing human population.
Invasive shrubs in Northeastern forests that sprout leaves earlier in the spring and keep them longer in the fall not only absorb more sunlight than native shrubs, but their foliage lowers air temperatures on the forest floor, likely giving them another competitive advantage.
Scientists discover endophytic bacteria that can survive the unfavorable interior of passion fruit seeds and get transmitted to the seedlings on germination
A study into the energy-making process in plants could help engineer crops more resistant to stress or bacteria that produce pharmaceuticals.
How flowers form properly within a limited time frame has been a mystery. Now researchers have found that KNUCKLES, a small multi-functional protein, supports the correct timing of floral development for the proper formation of flower reproductive organs
Velloziaceae is a monocot family that is made up of five genera and c. 250 species with a disjunct distribution in Africa mainland, Madagascar, Arabian Peninsula, China and South America. They are recognized as the largest lineage of vascular plants that can tolerate desiccation, hence are resurrection plants.
European old-growth forests are estimated to occupy only 0.7% of the total forested area; they are of prime ecological value, representing small vestiges of how Europe’s past primeval forest may have looked. In addition, old-growth forests provide various and important ecosystem services, such as biodiversity maintenance, long-term carbon storage, and landscape uniqueness. Therefore, old-growth forests represent valuable natural laboratories for evaluating how trees of different dimensions and ages respond to global change drivers, including climate warming and land-use changes. Although there is increasing attention on these ecosystems, knowledge of the long-term impacts of climate change in the Mediterranean environment is still limited. A recent study found that in Mediterranean mountainous area old-growth forests show remarkable resistance to climate warning.
Many important crop plants can be devastated by pathogens including bacteria, fungi and viruses. Knowing exactly how some plants respond could give researchers the information to breed crops with the best disease-fighting power or even design new and improved immune sensors in genetically modified plants.
Ferns are the second most species rich lineages of land plants and highly suitable to test the association between genome diversity and lineage diversification. Many studies have recovered substantial differences in genome diversity. However, less attention has been given to ferns.
aching and disinfecting agent. However, it is also constantly produced in living cells. Often as a byproduct of biological processes, sometimes intentionally, for example to kill pathogens. It is also thought that H2O2 plays an important role as a signaling molecule.
