Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Cloning, Gene Expression Analysis, and Phylogenic Relationship of dbat Gene from Iranian Endemic Yew (Taxus baccata L.)

Journal of Medicinal Plants, 2013
Background: Taxol is one of the most important anticancer agents that its supply mainly depends on biological processes. 10 - deacetyl baccatin III- O- acetyl transferase (dbat) gene is one of the key genes in Taxol biosynthetic pathway and it is ...

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

Boreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

A novel method based on high‐resolution imaging spectroscopy to predict fine‐root traits and the economics space of fresh tree roots

New Phytologist, EarlyView.
Maps of the estimated root nitrogen concentration in the < 0.5‐mm‐diameter classes of 20 woody species based on the imaging spectroscopy using the shortwave infrared spectral region. Summary Tree fine‐root morphological, anatomical, and chemical traits are important to reflect belowground resource acquisition strategies to support tree growth, but ...

Cell‐Specific Expression and Cellular Compartmental Regulation in Camptothecin Biosynthesis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant secondary metabolites such as monoterpenoid indole alkaloids (MIAs) show tightly regulated biosynthesis and accumulation in specific organelles of distinct cell types. However, the cell‐specific expression patterns of anticancer MIA camptothecin biosynthetic genes in Ophiorrhiza pumila and the regulatory mechanisms of camptothecin ...

Transcriptome analyses provide insights into the expression pattern and sequence similarity of several taxol biosynthesis-related genes in three Taxus species

BMC Plant Biology, 2019
Background Taxol is an efficient anticancer drug; however, the accumulation of taxoids can vary hugely among Taxus species. The mechanism underlying differential accumulation of taxoids is largely unknown. Thus, comparative analysis of the transcriptomes

Taxidea taxus

, 2020
Taxidea taxus (Schreber, 1777) American Badger Taxidea taxus is primarily distributed throughout western and central Oklahoma but also has been documented in eastern counties. Caire et al. (1989) reported specimen records from 32 counties and observations from three counties.
