Abstract
With the decline of cultivated land and increase of the population in recent years, an agricultural revolution is urgently needed to produce more food to improve the living standards of humans. As one of the foundations of synthetic biology, artificial chromosomes hold great potential for advancing crop improvement. They offer opportunities to increase crop yield and quality, while enhancing crop resistance to disease. The progress made in plant artificial chromosome technology enables selective modification of existing chromosomes or the synthesis of new ones to improve crops and study gene function. However, current artificial chromosome technologies still face limitations, particularly in the synthesis of repeat sequences and the transformation of large DNA fragments. In this review, we will introduce the structure of plant centromeres, the construction of plant artificial chromosomes, and possible methods for transforming large fragments into plant cells.
