New technique to help plant breeders develop drought resistant varieties faster

December 13th, 2017 / ISAAA, US

Scientists from the Canadian Light Source (CLS) have teamed up with researchers from the University of Saskatchewan (U of S) to develop a new technique to examine drought tolerance in wheat. Led by Chithra Karunakaran and Karen Tanino, the team developed a simple non-destructive method to screen hundreds of wheat …

Genes found in drought-resistant plants could accelerate evolution of water-use efficient crops

December 6th, 2017 / Oak Ridge National Laboratory

Scientists at the Department of Energy’s Oak Ridge National Laboratory have identified a common set of genes that enable different drought-resistant plants to survive in semi-arid conditions, which could play a significant role in bioengineering and creating energy crops that are tolerant to water deficits.
Plants thrive in drylands by keeping …

Blog: Brachiaria, the homecoming of African pasture grasses, Brachiaria grasses, which originated primarily from natural grasslands in Africa, do not look particularly remarkable. Yet these forage species for feeding farm animals are the most widely used in the tropics. Because Brachiaria is adapted to acidic, low-fertility soils and is much more …

Drought tolerant maize provides extra 9 months of food for farming families

October 11th, 2017 / CIMMYT

Drought is a major limiting factor for maize production and can reduce maize yields by up to nearly 40 percent. In the past 10 years, most farmers in southern Africa have experienced around 1–3 drought years, potentially due to climate change.
A new study from scientists with the International Maize and …

Drought resistant, higher-yielding GM rice developed by Japanese researchers

April 10th, 2017 / Genetic Literacy Project, US

Scientists at the RIKEN Center for Sustainable Resource Science have developed strains of rice that are resistant to drought in real-world situations. Published in Plant Biotechnology Journal, the study reports that transgenic rice modified with a gene from the Arabidopsis plant yield more rice than unmodified rice when subjected to …

Researchers map out the chemical pathways that help plants cope with drought

November 14th, 2016 / Natural Science News, Panama

A team of researchers has pinpointed some of the mechanisms used by plants to cope with drought conditions. The discovery of the specific genes and proteins involved may help plant breeders develop crops better suited to changing conditions brought on by global warming. The details were just published in the …
