Pinoresinol-lariciresinol reductase (PLR) is a key enzyme in podophyllotoxin (PTOX) biosynthesis pathway, which catalyzes the conversion of pinoresinol into secoisolariciresinol, central precursor for PTOX biosynthesis. Podophyllum peltatum an important anticancer species, and content obviously different from various plant organs. Therefore, investigation PLR gene expression facilitates underst...

Juniperus rigida (J. rigida) which is endemic to East Asia, has traditionally been used as an ethnomedicinal plant in China. This study was undertaken to evaluate the quality of J. rigida samples derived from 11 primary regions in China. Ten phenolic compounds were simultaneously quantified using reversed-phase high-performance liquid chromatography (RP-HPLC), and chlorogenic acid, catechin, po...

Treatment of neurons with taxol leads to the formation of microtubule bundles in which individual microtubules are much more closely spaced than in untreated neurons (Letourneau and Ressler, 1984). This suggests that taxol interferes with the mechanisms that regulate microtubule spacing in situ. I have determined whether treatment of neurons with taxol alters the composition of their microtubul...

a procedure was developed for rapid in vitro germination of linum album seeds by scarification and exposing to gibberellic acid (ga3) and kinetin (kn).  concentrations of podophyllotoxin (ptox) and related aryltetralin lignans α-peltatin, β-peltatin, 5’-demethoxy-6-methoxypodophyllotoxin and 6-methoxypodophyllotoxin (mptox) in l. album fresh plant organs were determined by hplc. a degree of var...
