Molecular Regulation of Cell Wall Structure During Wood Formation in Forest Trees

Journal of Natural Fibers
There is a growing demand for wood as a sustainable energy source and an essential carbon sink for ecosystems. Wood formation is a dynamic process involving plant radial growth in various stages, including vascular cambial cell proliferation, xylem ...

Drought and salinity stress remodel Asian rice (Oryza sativa) leaf development through cell‐type‐specific regulatory programs

New Phytologist, EarlyView.
Osmotic stressors induce developmental and physiological changes in rice (Oryza sativa) seedlings, which are modulated by cell‐type‐specific gene expression and regulatory networks. We exposed plants to two levels of drought and salinity stress and measured the effects of these stressors on developing leaves by measuring physiological traits, ion ...

The vascular cambium of trees and its involvement in defining xylem anatomy

, 2017
The growth of perennial plants from tall upright trees up to small prostrate dwarf shrubs is a complex of interlinked processes resulting in a three-dimensional body whereby meristematic tissues play a crucial role. Among the various fractions

Functional memory of drought affects leaf chemical defenses and microbial interactions in aspen

New Phytologist, EarlyView.
Experimental design of the common garden study. Summary Drought is an important driver of tree mortality, but its long‐term impacts on trait expression remain poorly understood. Leaves are a key interface at which trees respond to abiotic stress, and foliar traits such as chemical defenses and microbial communities may play a role in determining post ...

Reciprocal transport of carbon and nitrogen between plants and the hyphosphere microbiome in a temperate grassland

New Phytologist, EarlyView.
Overview of the experimental design and 13CO2 pulse‐labeling approach in the field. Summary Despite its relevance for plant nutrient acquisition, the role of the hyphosphere in structuring fungal–bacterial networks and mediating carbon–nitrogen (C–N) exchange under field conditions remains unclear.

Linking drought strategy to climate‐of‐origin in a widespread C4 grass: hydraulic traits, xylem anatomy and stomatal behaviour in Themeda triandra

New Phytologist, EarlyView.
Climate‐of‐origin of Themeda triandra populations used in this study. Summary Hydraulic, stomatal, and anatomical traits strongly influence plant performance under drought, but the extent to which these trait‐types are coordinated and relate to climate‐of‐origin remains vastly underexplored in herbaceous species relative to woody plants.

Coupled decline in growth and fine‐branching signals the onset of drought‐induced European beech mortality

New Phytologist, EarlyView.
Conceptual synthesis of drought‐induced mortality in European beech. Summary Severe and recurrent droughts have caused widespread canopy decline and mortality in European forests. Drought‐induced mortality occurs when structural damage and physiological dysfunction impair a tree's ability to recover, yet it remains unclear when trees transition from ...

Carbohydrate content governs growth‐storage allocation during recovery from carbon depletion

New Phytologist, EarlyView.
Conceptual framework for competing hypotheses of growth‐storage carbon allocation during recovery from carbon limitation. Summary How plants prioritize carbon (C) allocation between growth and storage remains an outstanding question, limiting predictions of forest C cycling and ecosystem resilience following periods of C limitation. To address this gap,

Transport of Amino Acids via Xylem and Phloem in Detached Wheat Shoots [PDF]

, 1991
In maturing wheat ears the xylem predominantly feeds the glumes, while the phloem is directed to the developing grains. A transfer of amino acids and rubidium from the xylem lo the phloem was observed in the peduncle.
