Archaeological evidence reveals the impacts of ancient hunter-gatherers and settlers on tropical forests over the last 45,000 years. Archaeology can thus play an important role in promoting heritage and informing conservation and policy-making.
A Review Article describes recent progress in plant genome editing by introducing newly developed editing tools and methods and their application. The associated challenges and future prospects are also discussed.
A Review Article highlights knowledge of miRNA function in orchestrating distinct agronomic traits by summarizing recent functional analyses of 65 miRNAs in 9 major crops and discusses the potential application of miRNAs as a tool in crop improvement.
Invasive plants pose a particular environmental management issue given rapid environmental change and an unpredictable future. Productive connections have recently been established between social and natural science approaches to the problem.
Fifty per cent of the nitrogen fertilizer used globally is lost as ammonia, nitrate or nitrous oxide. Nitrification inhibitors, exuded by plant roots, play a role in reducing those losses both naturally and in the service of sustainable agriculture.
The role of nodule cysteine-rich (NCR) peptides during the nitrogen-fixing symbiosis is complex. They are more than just antimicrobial compounds used by the host to control bacterial growth, as previously thought.
Molecular dating has suggested that angiosperms existed earlier than the Late Cretaceous. Scattered fossil evidence for Triassic or Jurassic angiosperms exists but this Review concludes that the case remains unproven at best.
