Epigenetic Crop Hardening is a genetic modification technique that rapidly adapts crops to environmental stresses like drought and salt without altering the DNA sequences. This is achieved by using CRISPR-off switches and chemical modifiers to activate latent stress-response genes.
It addresses the challenge of rapidly adapting crops to changing environmental conditions caused by climate change, such as increased drought and salinity levels in agricultural lands.
The process involves identifying and activating specific epigenetic marks on genes related to stress responses in plants. By utilizing CRISPR-off switches, which are essentially modified versions of the CRISPR-Cas9 system that do not cut DNA but instead modify gene expression, scientists can activate dormant or silenced genes responsible for enhancing plant resilience under adverse conditions. Chemical modifiers are then applied to further enhance this activation process.
The manufacturing process involves identifying target genes through extensive genetic analysis, designing CRISPR-off switches and chemical modifiers, and then applying these tools to plant cells. This is a complex but relatively fast process compared to traditional genetic modification techniques.
The build process includes gene identification, CRISPR-off switch design, chemical modifier development, and subsequent application in plants through transformation methods like Agrobacterium-mediated transformation or direct DNA delivery systems.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking required for certain genetic transformation methods. Overall, operational power requirements are modest but manufacturing processes require significant energy input.
