Summary Plant architecture influences the microenvironment throughout canopy layer. Plants with a more erect leaf allow for an increase in planting densities and light to reach lower leaves. This is predicted crop carbon assimilation. Frictional resistance wind reduces air movement canopy, resulting higher humidity. By increasing proportion of photosynthesis humid gains efficiency water use might be expected, although this may slightly offset by open erectophile form canopy. An anatomical feature members Poaceae family that impacts angle articulated junction sheath blade, which also bares ligule auricles. Mutants, lack ligules auricles, show no articulation at junction, leaves are near vertical. In maize, these phenotypes termed liguleless result from null mutations genes: ZmLG1 (Zm00001eb432520) ZmLG2 (Zm00001eb147220). sorghum, SbiRTx430.06G264300 ( Sb LG1) SbiRTx430.03G392300 LG2) annotated as respective maize homologues. A hair‐pin element designed down‐regulate both LG1 LG2 was introduced into grain sorghum genotype RTx430. Derived transgenic events harbouring failed develop displayed reduced angles vertical, but less vertical than mutations. Under field settings, plots sown having phenotype levels, led increases above‐ground biomass seed yield, without use.

Climate change is altering our environment, subjecting multiple agroecosystems worldwide to an increased frequency and intensity of abiotic stress conditions such as heat, drought, flooding, salinity, cold and/or their potential combinations. These stresses impact plant growth, yield survival, causing losses billions dollars agricultural productivity, in extreme cases they lead famine, migration even wars. As the rate environment has dramatically accelerated recent years, more research urgently needed discover develop new ways tools increase resilience crops different conditions. In this theme issue, studies addressing molecular, metabolic, physiological responses other plants challenges are discussed, well exploit these mechanisms biotechnological applications aimed at preserving increasing crop under changing climate This article part issue ‘Crops stress: can we mitigate impacts on agriculture launch ‘Resilience Revolution’?’
