A xylem-produced peptide PtrCLE20 inhibits vascular cambium activity in Populus. [PDF]
Plant Biotechnol J, 2020 SummaryIn trees, lateral growth of the stem occurs through cell divisions in the vascular cambium. Vascular cambium activity is regulated by endogenous developmental programmes and environmental cues. However, the underlying mechanisms that regulate cambium activity are largely unknown.

Roots Structure and Development of Austrobaileya scandens (Austrobaileyaceae) and Implications for Their Evolution in Angiosperms [PDF]
, 2020 Since the resolution of the ANA grade [Amborellales, Nymphaeales, Austrobaileyales] as sister to all other flowering plants, a few comparative studies of root structure have suggested that some of their anatomical traits could be of importance to ...

Frontiers in Plant Science, 2020 The plasticity of plant development relies on its ability to balance growth and stress resistance. To do this, plants have established highly coordinated gene regulatory networks (GRNs) of the transcription factors and signaling components involved in ...

Epigenetics at the crossroads of secondary growth regulation
Frontiers in Plant Science, 2022 The development of plant tissues and organs during post-embryonic growth occurs through the activity of both primary and secondary meristems. While primary meristems (root and shoot apical meristems) promote axial plant growth, secondary meristems ...

Stem cambial variants of Taiwan lianas
Botanical Studies, 2022 Background Cambium in lianas, responsible for secondary growth, develop diverse and diagnostic traits during the climbing phase. Studies on the cross-section of Taiwanese liana cambial variants are scarce.

Overexpression of a Prefoldin β subunit gene reduces biomass recalcitrance in the bioenergy crop Populus. [PDF]
, 2020 Prefoldin (PFD) is a group II chaperonin that is ubiquitously present in the eukaryotic kingdom. Six subunits (PFD1-6) form a jellyfish-like heterohexameric PFD complex and function in protein folding and cytoskeleton organization.

Are the anatomical traits of stems and leaves good indicators of habitat specificity in closely related Myrtaceae species from Patagonia? [PDF]
Acta Botânica Brasílica, 2023 The anatomical attributes of young stems and leaves of newly formed shoots were studied for five Patagonian species of Myrtaceae: Amomyrtus luma, Ugni molinae, Luma apiculata, Myrceugenia exsucca and M. ovata var. nannophylla.

The vascular cambium revisited
IAWA Journal, 2023 Summary The vascular cambium presents fundamental questions about the evolution and developmental biology of plants. Over time, our perspectives of the vascular cambium have changed as new molecular and genetic approaches have augmented anatomical observations and are now providing new insights into longstanding topics related to vascular cambium ...

On growth and flow: hydraulic aspects of aboveground meristems. [PDF]
New PhytolSummary Water is essential for plant growth under both normal and stress conditions. Aboveground, two key meristems control plant development: the shoot apical meristem and the vascular cambium. Here, stem cell maintenance and cell differentiation are affected by hydraulic fluctuations across seasons, days, or even hours. Water fluxes, turgor pressure,
