A mechanism used by a fungal pathogen to promote spread of the devastating cereal crop disease, blast, has been revealed in fine detail.

Farmers are becoming more involved than ever in the work of developing new, sustainable crop varieties, with a recent Alliance study showing how a “citizen science” approach for on-farm experimentation called tricot, generated agricultural data via local organizations in Central America.
Over the last two centuries, human actions have resulted in rising temperatures, a massive carbon imbalance, and tremendous biodiversity loss. However, there are cases in which human stewardship seems to help remediate this damage. Researchers examined tropical forests across Asia, Africa and the Americas and found that the forests located on protected Indigenous lands were the healthiest, highest functioning, most diverse, and most ecologically resilient.
The central biocatalyst in photosynthesis, Rubisco, is the most abundant enzyme on earth. By reconstructing billion-year-old enzymes, a team of Max Planck Researchers has deciphered one of the key adaptations of early photosynthesis. Their results not only provide insights into the evolution of modern photosynthesis but also offer new impulses for improving it.
A research team has measured the dynamic leakiness of CO2 from C4 plants. Previous studies had measured the leakiness under steady-state conditions, but this group took the measurements to prove that leakiness can and should be measured as a dynamic parameter.
Foxtail millet, Setaria italica, is one of the oldest and more resilient crops worldwide. Compared to rice and wheat, millet has excellent climate resilience and requires less fertilizer, pesticides, and irrigation than mainstream cereals. In addition, millet-based foods are nutritionally superior to other cereal crops. With these properties, this crop is poised to play an important role to strengthen food security for the world’s growing population.
Biologists have revealed how plants suppress the formation of stomata, the microscopic pores on their surface, to limit water loss during drought conditions.
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.
