Thidiazuron (N-phenyl-N'-1,2,3-thiadiazol-5-ylurea; TDZ) is an artificial plant growth regulator that is widely used in plant tissue culture. Protocorm-like bodies (PLBs) induced by TDZ serve as an efficient and rapid in vitro regeneration system in Rosa species. Despite this, the mechanism of PLB induction remains relatively unclear. TDZ, which can affect the level of endogenous auxins and cyt...

Tree peony (Paeonia ostii) is an ornamental flowering plant that generally recalcitrant to establishment of a mature somatic embryo regeneration system in vitro. Glucose-6-phosphate translocator (GPT) plays important regulatory role embryogenesis plants. In this study, PoGPT1 was cloned, and bioinformatic analysis functional verification the gene were performed. The results showed encoded polyp...
