Construction of an Editing System for Forest Tree Genomes Based on an Efficient Visual Screening Marker in <i>Eucalyptus urophylla</i> × <i>Eucalyptus grandis</i>

Herein, the clustered regularly interspaced short palindromic repeats (CRISPRs)/CRISPRs-associated protein 9 (Cas9) technology for genome editing was used to develop an efficient gene editing system for <i>Eucalyptus urophylla</i> × <i>Eucalyptus grandis</i> and generate a ne...

description Herein, the clustered regularly interspaced short palindromic repeats (CRISPRs)/CRISPRs-associated protein 9 (Cas9) technology for genome editing was used to develop an efficient gene editing system for <i>Eucalyptus urophylla</i> × <i>Eucalyptus grandis</i> and generate a new <i>Eucalyptus</i> germplasm with reduced lignin content in the pulp for environmental sustainability in papermaking. By targeting the cinnamate-4-hydroxylase (<i>C4H</i>) gene in <i>E. urophylla</i> × <i>E. grandis</i>, the recombinant plasmid pHEE401E-<i>35S-RUBY-EuC4H</i> was constructed through homologous recombination. This plasmid was then transformed into <i>E. urophylla</i> × <i>E. grandis</i> callus tissue. Using the <i>RUBY</i> gene as a marker, positive transformants were screened based on the callus tissue phenotype. Subsequent PCR and sequencing confirmed the successful creation of mutants with a significantly edited <i>EuC4H</i> gene. This method offers a valuable framework and guidance for genetically improving and establishing an efficient gene editing system in <i>Eucalyptus</i>.
