英文摘要: Abstract(#br) Background(#br)The phytohormone ethylene (ET) is a key signaling molecule for inducing the biosynthesis of shikonin and its derivatives, which are secondary metabolites in Lithospermum erythrorhizon . Although ETHYLENE INSENSITIVE3 (EIN3)/EIN3-like proteins (EILs) are crucial transcription factors in ET signal transduction pathway, the possible function of EIN3/EIL1 in shikonin biosynthesis remains unknown. In this study, by targeting LeEIL-1 ( L. erythrorhizon EIN3-like protein gene 1) at the expression level, we revealed the positive regulatory effect of LeEIL-1 on shikonin formation.(#br) Results(#br)The mRNA level of LeEIL-1 was significantly up-regulated and down-regulated in the LeEIL-1 -overexpressing hairy root lines and LeEIL-1 -RNAi hairy root lines, respectively....
