A group of researchers may have found a way to reverse falling crop yields caused by increasingly salty farmlands throughout the world. Brigham Young University scientists have used bacteria found in the roots of salt-tolerant plants to successfully inoculate alfalfa plants against overly salty soil.
In new research published in the journal Science, a team of biologists, including Colorado State University Assistant Professor of Biology Marc Nishimura, have shed new light on a crucial aspect of the plant immune response. Their discovery, revealing how plant resistance proteins trigger localized cell death, could lead to new strategies for engineering disease resistance in next-generation crops.
At an unprecedented scale, researchers have now catalogued the array of surveillance tools that plants use to detect disease-causing microbes across an entire species.
A research team investigated the impact of extreme fires on previously intact carbon stores by studying the soil and vegetation of the boreal forest and how they changed after a record-setting fire season in the Northwest Territories in 2014. They collected 200 soil samples and used radiocarbon dating to estimate the carbon age. They found combustion of legacy carbon in nearly half of the samples taken from young forests (less than 60 years old).
Study assembles canola root's dose-response curves for nitrogen sources.
Simple, fast and flexible: it could become significantly easier to vaccinate plants against viruses in future. Scientists at Martin Luther University Halle-Wittenberg (MLU), the Leibniz Institute of Plant Biochemistry (IPB) and the National Research Council in Italy (CNR) have developed a new method for this purpose. It enables the rapid identification and production of precisely tailored substances that combat different pathogens. The researchers discuss their work in the next edition of Nucleic Acids Research.
A research group led by Prof. LE Jie at the Institute of Botany of the Chinese Academy of Sciences found a genetic suppressor of flp stomatal defects. They found that RPA2a, a core subunit of Replication Protein A (RPA) complexes, acted downstream from the core cell cycle genes of CDKB1 to ensure terminal division during stomatal development and the formation of paired guard cells to create functional stomata units.
A research team led by Namiko Nishida from Kobe University have succeeded in comprehensively identifying the long noncoding ribonucleic acids (IncRNAs) that are expressed when Chinese cabbage is temporarily exposed to cold temperatures for four weeks.
When insects carry the pollen from one flower to another to pollinate them, the pollen must attach to and detach from different surfaces. Scientists from Kiel University have discovered that the mechanisms are far more complex than previously assumed. They differ depending on the duration of the contact and the microstructure of the plant surfaces. The results could be interesting for drug delivery and for developing alternative strategies in agriculture and food production.
By analysing 138 experiments, researchers have mapped the potential of today's plants and trees to store extra carbon by the end of the century.
