The intrusive growth of initial cells in re-arangement of cells in cambium of Tilia cordata Mill.

open access: yesActa Societatis Botanicorum Poloniae, 2014
In the cambium of linden producing wood with short period of grain inclination change (2-4 years), the intensive reorientation of cells takes place. This is possible mainly through an intrusive growth of cell ends from one radial file entering space ...

Strigolactone‐mediated architecture regulation and stress resilience: Insights and innovations for crop breeding

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review summarizes the discovery, biosynthesis, and transport of strigolactone, and the D14‐D3/MAX2‐D53/SMXLs signaling module. It highlights diverse roles of strigolactone in plant architecture, stress responses, and crop breeding, including species‐specific functions, hormonal crosstalk, and agricultural applications.

Vessel differentiation in isolated stem segments of Fraxinus excelsior L. after treatment with auxin

open access: yesActa Societatis Botanicorum Poloniae, 2014
Experiments were carried out on isolated stem segments of ash collected from natural conditions during the winter dormancy season. In order to stimulate cambial activity and vessel differentiation the internodes were treated with auxin.

Hedger of Last Resort: Evidence from Brazilian FX Interventions, Local Credit, and Global Financial Cycles

open access: yesThe Journal of Finance, EarlyView.
ABSTRACT We show that FX interventions can be effective, particularly in attenuating global financial spillovers. We exploit global financial shocks and Brazilian central bank interventions in FX derivatives using three matched administrative registers: bank credit (to firms), foreign credit to banks, and employer‐employees. After the U.S.

Development of the Vascular Cambium of Taxodium ascendens and Its Seasonal Activities in Subtropical China

open access: yes, 2023
The vascular cambium is an extensive and permanent secondary meristem with wood cells products of periclinal divisions commonly contributed to two directions and arranged in radial files of trees.

Intra‐annual transfer of hydrogen and oxygen isotopic signals from water and sugar precursors to tree rings: Processes and mechanisms

open access: yesNew Phytologist, EarlyView.
Intra‐annual radial growth of beech and spruce in 2021 and 2022. Summary The oxygen (δ18O) and hydrogen (δ2H) isotope compositions of leaf and xylem water shape tree‐ring isotope baselines, while the fraction of sugars undergoing isotopic modification downstream of leaves (fO, fH) determines the dominant hydrologic signal.

Molecular regulation of vascular cambium identity and activity [PDF]

open access: yes, 2015
In plants, secondary development and wood formation originates from the cell divisions within the vascular meristem, where the vascular stem cells are located. This thesis work presents my results on the molecular regulation of vascular cambium stem cell

Cross‐stage single‐cell and spatial metabolome analyses reveal periderm specialization and tanshinone biosynthesis in Salvia miltiorrhiza roots

open access: yesNew Phytologist, EarlyView.
Biosynthesis and accumulation of tanshinones in the periderm of Salvia miltiorrhiza during secondary root growth. Summary Perennial herbs develop long‐lived roots that undergo repeated cycles of secondary growth, during which the periderm functions as a protective barrier and a major site of specialized metabolite accumulation.

Spatiotemporal Metabolome and Single‐Nucleus Transcriptome Integration Illuminates an Auxin Gradient Orchestrated by NtTAC1 Underlying Leaf Angle Regulation in Tobacco

open access: yesPlant Biotechnology Journal, EarlyView.
Proposed model of TAC1‐mediated leaf angle regulation in tobacco. ABSTRACT Plant architecture is key to crop yield, with leaf angle being critical for high‐density cultivation. Although TAC1 represents a promising regulator of leaf angle for breeding, its molecular mechanism remains poorly understood, particularly at single‐nucleus resolution. Here, we
