Rising temperatures put Africa’s rice production at risk

January 18th, 2018 / African Farming, UK

A new modelling study published today warns that the dry-season irrigated rice in West Africa’s Sahel region has reached the critical threshold of 37 degrees Celsius – the tipping point. Further temperature rise could devastate rice yields in this region due to decreasing photosynthesis at high temperatures.
This is an ominous …

Scientists use CRISPR-Cas9 technology to improve drought and salt tolerance in rice

January 11th, 2018 / ISAAA, US

The ∆ 1 -pyrroline-5-carboxylate synthetase (P5CS) is the rate-limiting enzyme in proline (Pro) synthesis and is involved in drought and salt stress tolerance in plants. An OsP5CS gene was isolated from a stress-treated commercial rice variety, BC15.
The length of rice OsP5CS was 2173 nucleotides, containing an ORF encoding for …

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 …

‘Super beans’ raise hopes in hunger-prone parts of Africa

December 4th, 2017 / WRAL.com

Richard Opio dipped a dirt-stained hand into the pinkish beans, marveling at the dramatic changes they’ve made for his family. They used to harvest two sacks of normal beans; now they take in six.
The so-called “super bean,” a fast-maturing, high-yield variety, is being promoted by Uganda’s government and agriculture experts …

GM plant species numbers set to dramatically increase

December 4th, 2017 / Cosmos, Australia

Genetic modification of food crops is, depending on your point of view, a wondrous technological solution to feed a growing global population or a hubris-soaked scientific monstrosity sowing the seeds of environmental apocalypse.
Yet the war over GM crops, though intense, has so far been restricted to a small number of …

B4FA Fellow Lominda Afedraru reports:
There is increasing use of processed fertilizer by large scale farmers in the country with the aim of increasing their farm productivity.
Uganda’s smallholder agricultural sector continues to register one of the lowest fertilizer applications in sub-Saharan Africa.
The statistics indicates that Ugandan farmers use 1 to 1.5 …

Prickly pear cactus Is ‘miracle’ crop for dry regions

November 28th, 2017 / Thomson Reuters

It is spiky, alien-looking and can be found decorating homes around the world, but experts say the prickly pear cactus could help alleviate hunger in arid regions due to its ability to thrive in harsh conditions and its multiple uses.
