Resumen:
Adverse environmental conditions pose serious limitations toagricultural production. Classical biotechnological approachestowards increasing abiotic stress tolerance focus on boostingplant endogenous defence mechanisms. However,overexpression of regulatory elements or effectors is usuallyaccompanied by growth handicap and yield penalties due tocrosstalk between developmental and stress-responsenetworks. Herein we offer an overview on novel strategies withthe potential to overcome these limitations based on theengineering of regulatory systems involved in the fine-tuning ofthe plant response to environmental hardships, including posttranslationalmodifications, small RNAs, epigenetic control ofgene expression and hormonal networks. The developmentand application of plant synthetic biology tools and approacheswill add new functionalities and perspectives to geneticengineering programs for enhancing abiotic stress tolerance.
