520	3		_aDrought is one of the main abiotic factors that affect agricultural productivity, jeopardizing food security. Modern biotechnology is a useful tool for the generation of stress-tolerant crops, but its release and field-testing involves complex regulatory frameworks. However, gene editing technology mediated by the CRISPR/Cas9 system is a suitable strategy for plant breeding, which can lead to precise and specific modifications in the plant genome. The aim of the present work is to produce drought-tolerant plant varieties by modifying the trehalase gene. Furthermore, a new vector platform was developed to edit monocot and dicot genomes, by modifying vectors adding a streptomycin resistance marker for use with the hypervirulent Agrobacterium tumefaciens AGL1 strain. The gRNA design was based on the trehalase sequence in several species of the genus Selaginella that show drought tolerance. Arabidopsis thaliana carrying editions in the trehalase substrate-binding domain showed a higher tolerance to drought stress. In addition, a transient transformation system for gene editing in maize leaves was characterized.
