**Abstract:** Climate change is exacerbating drought conditions globally, severely impacting crop yields. *Brassica napus* (rapeseed), a crucial oilseed crop, is particularly vulnerable. This study details a novel approach for enhancing drought tolerance in *B. napus* by pyramiding the *DREB1F* and *NCED3* genes, both known to play critical roles in drought response, using CRISPR-Cas12a technology. We combine advanced phenotyping techniques with QTL mapping to identify optimal genomic locations for targeted gene editing, significantly exceeding existing genetic improvement strategies through precision and combinatorial engineering.

يشعر ملايين الأمريكيين بحزن عميق وغضب متزايد إزاء قتل مصلحة الهجرة والجمارك لأم لثلاثة أطفال، ويحتج الآف الناس في مئات المدن والبلدات في جميع أنحاء البلد. يدل هذا على تحول عميق في المشاعر.
