Lesson 2 • Delivery of CRISPR Components into Plants

Compares DNA, RNA, and ribonucleoprotein delivery routes for Cas9 and guide RNA into plant cells. Delivery method choice affects editing efficiency, off-target risk, and regulatory status.

Lesson 3 • Guide RNA Design and Off-Target Analysis

Covers bioinformatic tools for guide RNA selection, specificity scoring, and off-target prediction in plant genomes. Rigorous design minimizes unintended mutations in edited lines.

Lesson 4 • Detection and Analysis of Editing Events

Teaches T7E1 assay, amplicon sequencing, and whole-genome sequencing to detect and quantify editing outcomes. Accurate genotyping is required to select homozygous edited lines for downstream use.

Lesson 1 • Protein Expression and Proteomics
