Through collaborative efforts across scientific disciplines and stakeholders, we can harness the full potential of CRISPR-Cas9 to address the complex challenges facing our planet and pave the way for a more resilient and food-secure future [4]. Understanding CRISPR-Cas9 CRISPR-Cas9, short for Clustered Regularly Interspaced Short Palindromic Repeats and CRISPR-associated protein 9, is a genome-editing tool derived from the bacterial immune system [5]. It allows researchers to precisely modify DNA sequences within the genome of an organism. The system consists of two main components: the Cas9 protein, which acts as molecular scissors, and a guide RNA (gRNA) that directs Cas9 to the target DNA sequence. At the heart of the CRISPR-Cas9 revolution lies a sophisticated molecular machinery capable of precise genome manipulation. Understanding the intricacies of CRISPR-Cas9 is fundamental to appreciating its profound impact on plant biology and agriculture.
