Trouble brewing

Ethiopian coffee farming faces major challenges in the decades to come, not least due to climate change. Significant resilience, and even a substantial increase in coffee production area, could be acheived by precise and timely relocation of coffee-growing areas. But longer-term prospects are less optimistic.

  • Science is a competitive business and in any competition there can be ‘shortcuts’ to success. Transparency is the only way to guarantee that research results can be trusted more than some sporting achievements.

  • A high-quality sunflower genome provides insight into Asterid genome evolution. Moreover, integrative analyses based on quantitative genetics, expression and diversity data uncover the gene networks and candidate genes for oil metabolism and flowering time, two important agronomic traits for sunflowers.

  • The nitrate signalling pathway now has a backbone. CPK calcium-dependent kinases are the long-awaited molecular link between major players in this pathway, the membrane-located nitrate transceptor NRT1.1 and the NLP transcription factors.

  • Plants defend themselves from invading viruses using RNA silencing. However, plant viruses try to spoil this defensive mechanism by expressing one or more proteins that act as RNA silencing suppressors. One such protein spoils plant defence by transporting the silencing signal into the peroxisomes to avoid its systemic spread.

    Review Article
  • Before maize-based agriculture, there existed in eastern North America a crop system that is now only known from archaeological data. Present research is exploring whether these crops, which sustained ancient societies for millennia, can be re-domesticated.
