Biologists often use green fluorescent protein (GFP) to see what happens inside cells. GFP, which scientists first isolated in jellyfish, is a protein that changes light from one color into another. Attaching it to other proteins allows researchers to find out if cells produce those proteins and where within cells to find them. This in turn shows how cells deliver and use genes.
Plant leaves can cope with much higher salt concentrations than roots. The underlying mechanism may help to develop more salt-tolerant crops. When there is a lack of water, heat or intensive irrigation, the level of common salt (sodium chloride) in the soil increases. However, most crops are sensitive to salt. They react to the increasing soil salinity by greatly reducing their growth. This leads to a reduction in the harvest.
Genebanks play an important role in the long-term conservation of plant genetic resources for food and agriculture. Out of 1,800 genebank collections worldwide, more than 600 are in Europe. This vast array of crop diversity can be exploited to make our crops more nutritious, productive and resilient to pests, diseases and environmental changes, only if we have information about it.
Pre-treatment with ethanol activates molecular processes that could allow crops to tolerate a warming world. A dose of ethanol, better known as common alcohol, can enable plants to withstand heat stress that might otherwise kill them, biologists have found. This could offer a low-cost way to make crops more resilient to the effects of climate change.
A research group has developed a rapid breeding strategy to generate tomato lines with different colored fruits from red-fruited materials by CRISPR/Cas9-mediated multiplex gene editing.
As days grow colder and shorter, and many of us find ourselves entrenched in winter, you wouldn’t be mistaken for feeling a noticeable reduction in activity around you. However, in certain crops such as winter wheat and barley, this cold season holds the key to flowering in the spring. This well-studied process, called vernalization, requires the plant to sense appropriate conditions – i.e., low temperature and short day-length – usually early in development to “overwinter” through several inhospitable months.
Researchers have studied how certain bacteria perform photosynthesis using low-energy light, which could be engineered into crops to boost production. By studying the way two bacteria perform the difficult chemistry of photosynthesis, a team has discovered the trade-offs they make when using lower-energy light. This could inform plant genetic engineering that aims to make crop and biomass production more efficient.
Researchers have identified a new reason to protect mangrove forests: they’ve been quietly keeping carbon out of Earth’s atmosphere for the past 5,000 years.
A new banana fungus is rapidly spreading across the globe. It hit Africa a decade ago, and now spreads, a genetic study reveals. They state that the disease poses a threat to Africa’s food security.
Scientists use genomic data to resolve the phylogeny of zygnematophyte algae and pinpoint several emergences of multicellularity in the closest known relatives of terrestrial plants.
