Plastid-to-nucleus DNA transfer provides a rich genetic resource to the complexity of plant nuclear genome architecture. To date, the evolutionary route of nuclear plastid DNA (nupt) remain unknown in conifers. We have sequenced the complete plastomes of two yews, Amentotaxus formosana and Taxus mairei (Taxaceae of coniferales). Our comparative genomic analyses recovered an evolutionary scenari...

TWO experiments were carried out to test the hypothesis that herbivory induces higher levels of taxanes in the bark of two year old Taxus media cv Hicksii cuttings. For the first experiment bark was cut 1.0 mm deep every 5.0 mm in two groups of cuttings; with 0.1% 2,4-D applied over the wounded bark in one group. Both groups and a control were harvested one week later. In the second experiment ...
