  • Citizen scientists from 200 years ago and today help shed light on climate change trends - Citizen science observations across two centuries reveal a┬ádramatic, climate-driven shift to earlier leaf out and flowering, which varies across settings, species and functional groups. Plants in urban areas, insect pollinated trees, and early-season species show the greatest rate of advancement overall. This unprecedented comparison of historic-modern network observations illustrates how long-term monitoring and citizen science efforts are invaluable for ecological forecasting and discovery.
  • Photorhabdus luminescens -- a true all-rounder: Insect pathogenic bacterium also helps to combat fungal infestation - The bacterium Photorhabdus luminescens is already used as bioinsecticide to protect crops against a wide range of insect pests. Researchers have recently demonstrated that P. luminescens can also protect plants against fungal infection.
  • Case solved: The biosynthesis of strychnine elucidated - A research team has disclosed the complete biosynthetic pathway for the formation of strychnine in the plant species Strychnos nux-vomica (poison nut). The researchers identified all genes involved in the biosynthesis of strychnine and other metabolites and expressed them in the model plant Nicotiana benthamiana. This enabled them to show that these extremely complex and pharmacologically important molecules can be synthesized using 'metabolic engineering' methods.
