Scientists have discovered how plants manage to live alongside each other in places that are dark and shady. Moderate shade or even the threat of shade – detected by phytochrome photoreceptors – causes plants to elongate to try to outgrow the competition.
An international study has revealed the structure of a membrane-remodeling protein that builds and maintains photosynthetic membranes. These fundamental insights lay the groundwork for bioengineering efforts to strengthen plants against environmental stress, helping to sustaining human food supply and fight against climate change.
As well as bright colours and subtle scents, flowers possess many invisible ways of attracting their pollinators, and a new study shows that bumblebees may use the humidity of a flower to tell them about the presence of nectar, according to recent research.
The first plant embryo gene expression atlas at the single cell level was developed by a team of researchers. The work is a milestone on the way to uncovering the molecular mechanisms that determine how the most fundamental plant cell-types are established at the beginning of life.
Findings reveal how plants use a blend of genes, geography, demography and environmental conditions to evolve defense chemicals over time.
The mystery of the formation of one of the most peculiar plant forms – the Romanesco cauliflower – has been solved by a team of international and multidisciplinar scientists.
Plants are constantly exposed to microbes: pathogens that cause disease, commensals that cause no harm or benefit, and mutualists that promote plant growth or help fend off pathogens. For example, most land plants can form positive relationships with arbuscular mycorrhizal fungi to improve nutrient uptake. How plants fight off pathogens without also killing beneficial microbes or wasting energy on commensal microbes is a largely unanswered question.
To describe something as slow and boring we say it’s “like watching grass grow”, but scientists studying the early morning activity of plants have found they make a rapid start to their day – within minutes of dawn.
Researchers have re-animated specimens of a fungus that causes coffee wilt to discover how the disease evolved and how its spread can be prevented.
Scientists have discovered a single gene that simultaneously boosts plant growth and tolerance for stresses such as drought and salt, all while tackling the root cause of climate change by enabling plants to pull more carbon dioxide from the atmosphere.
