AbstractThlbalfodplyistlyingregsiateityblendducndl tion growth.Genetic engineering has emerged as arevolutionary approach to enhance crop yields.Engineering C3 wheat to achieve C4 photosyntesiswithtlfatleasigodtityoahosiisosuly developed“C -like wheat”，a fully functional C4 -type Kranz anatomy has not yet been achieved.Further exploration is needed regarding the vascular development and cellular patterning mechanisms in C4 crops.Advances in mutant screening strategies and comparative genomic data mining are progressively deepening our understanding of the genetic basis underlying C4 anatomical formation.This review summarizes the molecular mechanisms of C4 photosynthetic pathways and outlines engineering strategies for converting C3 wheat to C4 photosynthesis，along with current challenges and future directions，in order to provide valuable references for achieving C4 engineering in wheat and offer solutions to ensure global food security.
