Ben-Gurion University plant biologist is figuring out how wild wheat protects itself from insects

Researchers at Ben-Gurion University have discovered two defense methods in wild emmer wheat that can protect cultivated wheat from insects. The wheat produces a poison called benzoxazinoid and has a coating of 'hairs' that prevent insects from burrowing, allowing for improved pest resistance

Global spread of powdery mildew through migration and trade

A research team uncovered the secret of powdery mildew's success by comparing genetic compositions of 172 strains from 13 countries on five continents. The pathogen was introduced to new regions through human migration and trade, undergoing hybridization with local species to form better-adapted hybrids.

Is organic farming always good for the environment? – Researchers create strategy to help decide

A recent study by Xi'an Jiaotong-Liverpool University provides a method to help farmers and policymakers decide whether organic farming is beneficial for the environment. The researchers analyzed international studies to find a threshold where organic farming's biodiversity gain outweighs its land requirements.

50 years of traditional crop conservation a success but some crops still lack protection

A recent study reveals that nearly two-thirds of traditional farmer crop varieties are already represented in genebanks, but conservation gaps persist for key crops like pearl millet and potatoes. The analysis highlights areas with high diversity in landraces, such as Bangladesh, Ethiopia, and India.

Genetic options ensure rust resistance is toast

Researchers at King Abdullah University of Science & Technology (KAUST) have identified a stem rust resistance gene in Aegilops sharonensis and transferred it to common wheat. The new transgenic wheat lines show high levels of resistance to the stem rust pathogen, providing hope for mitigating the devastating effects of climate change.

The hardy wild grass that could save our bread

A team of researchers identified a stem rust resistance gene from wild goat grass species Aegilops sharonensis, which can be cross-bred into wheat for immunity against deadly crop pathogens. The genetic potential of this hardy relative has been largely unexplored and holds promise for reducing the threat of the stem rust disease.

Climate change to stir up global agriculture within next decade, NASA/PIK study finds

A NASA/PIK study found that new climate conditions will push crop yields outside of their normal range in more regions, particularly in breadbasket areas. This could lead to severe losses for farmers unless they adapt quickly by changing planting dates or using different crop varieties.
