WebJun 28, 2024 · CRISPR-mediated genome editing has become a powerful tool for genetic modification of biological traits. However, developing an efficient, site-specific, gene knock-in system based on homology-directed DNA repair (HDR) remains a significant challenge in plants, especially in woody species like poplar. Here, we show that simultaneous … WebThus, as with the resection-dependent HDR pathway, the Brca1–Ctip interaction appears to be dispensable for MMEJ repair of chromosomal DSBs. Single-strand annealing (SSA) is a mutagenic mode of DSB repair that shares some features with MMEJ (Bennardo et al., 2008; McVey and Lee, 2008). In SSA, annealing occurs between long (>30 nucleotides ...

Defects in this regulation can induce genome instability and cancer. 53BP1 is critical for the control of DSB repair, promoting NHEJ, and inhibiting the 5' end resection needed for HDR.
