| description | Treatment with signalling precursors of trehalose-6-phosphate allows light-triggered release of trehalose-6-phosphate in
Arabidopsis thaliana
and increases the yield and drought resistance of spring wheat (
Triticum aestivum).
Chemical spray signals better crop yield
These authors present an alternative to the use of genetically modified (GM) crops to boost crop yield. Benjamin Davis and colleagues sprayed growing plants with signalling precursors of trehalose-6-phosphate (T6P). Uptake of the T6P analogues is triggered by sunlight, leading to T6P release in
Arabidopsis thaliana
, and increased yield and drought resistance in spring wheat (
Triticum aestivum
). The availability of chemical treatments of this type could be of particular importance in countries where GM crops are not widely accepted.
The pressing global issue of food insecurity due to population growth, diminishing land and variable climate can only be addressed in agriculture by improving both maximum crop yield potential and resilience
