Yield stability is fundamental to global food security in the face of climate change, and better strategies are needed for buffering crop yields against increased weather variability. Regional- scale analyses yield can support robust inferences about widely-grown staple crops, but have not been accomplished. We present a novel analytical approach, synthesizing 2000-2014 data on soil factors quantify their impact county-level maize four US states that vary widely these (Illinois, Michigan, Minnesota Pennsylvania). quantified as both 'downside risk' (minimum potential, MYP) 'volatility' (temporal variability). show excessive heat drought decreased mean stability, while higher precipitation stability. Soil water holding capacity strongly affected volatility all states, either directly (Minnesota Pennsylvania) or indirectly, via its effects MYP (Illinois Michigan). infer contributing help buffer variable weather. Given responds (within limits) agronomic management, our analysis highlights broadly relevant management variability, informs region-specific strategies.

Exploiting natural variation and genetic manipulation of stomatal conductance for crop improvement

Current Opinion in Plant Biology, Год журнала: 2019, Номер 49, С. 1 - 7

Rising global temperatures and more frequent episodes of drought are expected to drive reductions in crop yield, therefore new avenues for improving productivity must be exploited. Stomatal conductance (gs) balances plant CO2 uptake water loss, therefore, greatly impacting the cumulative rate photosynthesis use over growing season, which key determinants yield productivity. Considerable natural variation exists stomatal anatomy, biochemistry behavioural characteristics that impact on kinetics magnitude gs thus gaseous exchange between atmosphere. Exploiting these differences traits could provide novel breeding targets varieties potentially efficient have ability maintain and/or maximize a range diverse environments. Here we an overview behaviour, as well potential exploit such genetic manipulation improvement.
