Plant Peptides on the Rise: From Historical Insight to Future Applications

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant peptides constitute a rapidly expanding class of signalling molecules essential to plant physiology, mediating key processes such as development, stress adaptation, and immune responses. This review traces the history of plant peptide research, from the seminal discovery of systemin to the recent identification of non‐canonical peptides (

The configuration of events and cell growth activity in the storeyed cambium of the linden (Tilia cordata Mill.)

open access: yesActa Societatis Botanicorum Poloniae, 2014
A sample of wood from the trunk of the studied linden showed a periodic change in the orientation of the grain, occurring in an approximately two-year cycle.

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Similar Relative Carbon Costs for Construction and Storage of Sun and Shade Branches in Mature Temperate Trees

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Irradiance strongly affects the morphology, carbon (C) uptake and construction costs of leaves and branches. Within tree crowns, light decreases from the top downwards, but whether this translates to differences in the C balance of sun and shade branches remains unclear. Here, we combined a light‐driven photosynthesis model, parameterised with

Transcriptome-based WGCNA reveals the molecular regulation of xylem plasticity in acclimation to drought and rewatering in mulberry

open access: yesFrontiers in Plant Science
Xylem plasticity is important for trees to coordinate hydraulic efficiency and safety under changing soil water availability. However, the physiological and transcriptional regulations of cambium on xylem plasticity are not well understood. In this study,

Iron homeostasis in the annual and perennial stem zones of Arabis alpina

open access: yesPlant Biology, EarlyView.
Iron accumulates in secondary growth tissues in the perennial stem zone and is correlated with particular gene expression patterns in the perennial model plant Arabis alpina. Abstract Plants store nutrients, including the micronutrient iron, in bioavailable forms to support growth in subsequent seasons. The perennial lifestyle is preponderant in nature.

Preliminary study on phloemogenesis in Norway spruce: influence of age and selected environmental factors

open access: yesJournal of Forest Science, 2011
The process of phloem formation in Norway spruce (Picea abies [L.] Karst.) was analysed during the growing season 2009 in Rájec-Němčice locality (Czech Republic).

Legacies from early‐season hot drought: how growth cessation alters tree water dynamics and modifies stress responses in Scots pine

open access: yesPlant Biology, EarlyView.
Early‐season hot drought in Scots pine limits growth and productivity but improves resilience to late‐season drought through reduced water use. Abstract Tree responses to drought are well studied, but the interacting effects of drought timing on growth, water use, and stress legacy are less understood.

Positive mixture effects in pine–oak forests during drought are context‐dependent

open access: yesPlant Biology, EarlyView.
Mixture effects in drought‐stressed pine‐oak forests are context‐dependent, with Gambel oak and ponderosa pine benefiting from their complementarity under semi‐arid conditions. Abstract The increasing severity and frequency of droughts will play a pivotal role in shaping future forest ecosystems worldwide.

Plant stem cells: unity and diversity

open access: yesВавиловский журнал генетики и селекции, 2016
Stem cells are undifferentiated cells of multicellular organisms that can divide, self-renew and differentiate. Despite the differences of properties, general principles of the existence of stem cells can be distinguished in all multicellular organisms ...
