Golden inlaid polygonatum odoratum circular RNA PacircPEX and application thereof

The invention relates to the technical field of plant genetic engineering, in particular to gold-inlaid polygonatum odoratum circular RNA PacircPEX and application thereof. The cDNA (complementary deoxyribonucleic acid) nucleotide sequence of the gold inlaid fragrant solomonseal rhizome annular RNA PacircPEX is as shown in SEQ ID NO. 1 or SEQ ID NO. 2. The invention finds the effect of the circular RNA PacircPEX of the gold inlaid polygonatum odoratum on the plant drought resistance aspect, provides a theoretical basis and a gene resource for the resistance breeding of the gold inlaid polygonatum odoratum, provides a powerful tool for the transgenic research of the gold inlaid polygonatum odoratum, provides valuable circular RNA for the stress-resistant molecular breeding of the gold inlaid polygonatum odoratum, and has important significance for revealing the stress-resistant molecular mechanism of bamboos. The limitation of conventional breeding is broken through, and the bamboo breeding process is accelera
