Contrasted NCED gene expression across conifers with rising and peaking abscisic acid responses to drought [PDF]

Plant Stress
Conifer trees have diverse strategies to cope with drought. They accumulate the plant hormone abscisic acid (ABA) following a range of profiles from constantly rising to peaking and falling (R- and P-type) with direct effect on foliar transpiration.

Gram-Scale Access to (3,11)-Cyclotaxanes-Synthesis of 1-Hydroxytaxuspine C. [PDF]

Angew Chem Int Ed Engl
Belonging to the family of complex taxanes, 1‐hydroxytaxuspine C is a densely functionalized natural product. The synthesis was realized via a semisynthetic approach, starting from commercially available 10‐deacetylbaccatin III. A late‐stage photocyclization was utilized to install the characteristic transannular bond of complex taxanes, transforming ...

Comparative Genomic Analysis Reveals the Mechanism Driving the Diversification of Plastomic Structure in Taxaceae Species

Frontiers in Genetics, 2020
Inverted repeat (IR) regions in the plastomes from land plants induce homologous recombination, generating isomeric plastomes. While the plastomes of Taxaceae species often lose one of the IR regions, considerable isomeric plastomes were created in ...

Phylogenetics of native conifer species in Vietnam based on two chloroplast gene regions rbcL and matK

Czech Journal of Genetics and Plant Breeding, 2021
We used two chloroplast gene regions (matK and rbcL) as a tool for the identification of 33 local conifer species. All 136 sequences, 101 newly generated (14 species for gene matK; 16 species for gene rbcL) and 35 retrieved from the GenBank, were used in

Phylogenetics of Taxus Using the Internal Transcribed Spacers of Nuclear Ribosomal DNA and Plastid trnL-F Regions

Horticulturae, 2020
Taxus is a genus of trees and shrubs with high value in horticulture and medicine as a source of the anticancer drug paclitaxel. The taxonomy of the group is complex due to the lack of diagnostic morphological characters and the high degree of similarity

Spatiotemporal Distribution Patterns and Conservation Priorities of Gymnosperms With Different Leaf Shapes in China Under Climate Change. [PDF]

Ecol Evol
This study modeled the spatiotemporal distribution patterns of 71 rare gymnosperm species (including varieties) with five different leaf morphologies in China in response to climate change and found that approximately half of the species will experience significant range contractions and migrate to higher altitudes toward the northwest.
