Ethylene is a gaseous plant hormone that most likely became a functional hormone during
the evolution of charophyte green algae, prior to land colonization. From this ancient origin …

Evolutionary, as well as genetic, evidence suggests that vascular development evolved
originally as a cell death programme that allowed enhanced movement of water in the …

Postmortem lignification of xylem tracheary elements (TEs) has been debated for decades.
Here, we provide evidence in Zinnia elegans TE cell cultures, using pharmacological …

The development and growth of plants, as well as their successful adaptation to a variety of
environments, is highly dependent on the conduction of water, nutrients and other important …

All plant cells are encased in primary cell walls that determine plant morphology, but also
protect the cells against the environment. Certain cells also produce a secondary wall that …

The current status of lignocellulosic biomass as an invaluable resource in industry,
agriculture, and health has spurred increased interest in understanding the transcriptional …

Key message Environmental cues regulate plant vascular differentiation and plant evolution
through simple hormonal mechanisms of a single or a few moving signals. Abstract …

Plants are the primary producers of biomass on earth. As an almost stereotypic feature,
higher plants generate continuously growing bodies mediated by the activity of different …

Key message The spatial and temporal distributions of plant hormones during tree-ring
formation are beginning to be elucidated. Plant hormones play specific roles in tree-ring …

The radial growth of plant stem is based on the development of cribro-vascular cambium
tissues. It affects the transport efficiency of water, mineral nutrients and photoassimilates …
