Loss of the IR region in conifer plastomes: Changes in the selection pressure and substitution rate of protein‐coding genes

open access: yesEcology and Evolution, Volume 12, Issue 1, January 2022., 2022
There are significant differences in the selection pressure of 12 genes and the evolution rate of 9 genes between conifer and non‐conifer. This difference seems to be not related to the loss of typical IR regions but related to habitat. And the newly obtained short IR region plays a role in stabilizing the genome.

Stimulation of taxane production in suspension cultures of Taxus yunnanensis by oligogalacturonides [PDF]

open access: yes, 2010
When Taxus yunnanensis cells of 12-day-old cultures were exposed to oligogalacturonide (OGA) at 20-80µg ml-1 for 3 days, it was found that paclitaxel and 10-deacetyl baccatin III (10-DAB III) content peaked at 23 and 24 µg g-1 dry wt, respectively.

Effects of flavonoids derived from Taxus yunnanensis on p-glycoprotein and cytochrome P450 3A4 [PDF]

open access: yes, 2013
The intestinal uptake of paclitaxel is hampered by trans-membrane efflux transporters such as P-glycoprotein (P-gp), and paclitaxel is mainly metabolized by cytochrome P450 3A4 (CYP3A4) presented in the liver.

Hypoglycemic effects of the wood of Taxus yunnanensis on streptozotocin-induced diabetic rats and its active components [PDF]

open access: yes, 2006
Hypoglycemic effects of the H2O and MeOH extracts of the wood of Taxus yunnanensis were examined in streptozotocin (STZ)-induced diabetic rats. The H2O extract significantly lowered the fasting blood glucose level by 33.7% at a 100 mg/kg dose on ...
