gene-function
Gene-function research in plant science focuses on identifying and characterizing the specific roles that individual genes play in plant growth, development, metabolism, and stress responses. By linking genetic sequences to their biological functions, scientists can uncover the molecular mechanisms underlying traits such as yield, disease resistance, and environmental adaptation. This knowledge is foundational for crop improvement efforts and for understanding how plants respond to changing conditions at a molecular level.

Scientists developed a smarter gene-editing approach called TKC-MC that can reliably create rice plants with one working copy and one broken copy of a critical gene — something standard CRISPR tools struggle to do because they tend to knock out both copies, killing the plant.
A single intentional mismatch at position 11 or 17 in the gene-editing guide sequence was enough to enrich heritable heterozygous (one working / one broken copy) plants in sensitive gene targets.
For harder-to-edit gene targets, combining mismatches at positions 8 and 15 together maximized the yield of useful heterozygous plants.
Using a cocktail of three guide RNA variants (G1, M11, and M8+M15) together significantly increased the proportion of partially edited mutants compared to using a standard single guide RNA alone.
