Modeling Sub‐Grid Peatland Vegetation Dynamics in the ORCHIDEE‐PEAT Land Surface Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Peatlands store about one‐third of total global soil carbon. Vegetation composition strongly regulates peatland carbon dynamics. Global warming and climate‐driven ecohydrological changes are expected to alter peatland vegetation composition, necessitating accurate simulation of vegetation dynamics to predict future fate of peatland carbon.

Root Cortex Provides a Venue for Gas-Space Formation and Is Essential for Plant Adaptation to Waterlogging

Frontiers in Plant Science, 2019
Lysigenous aerenchyma, which develops by death and subsequent lysis of the cortical cells in roots, is essential for internal long-distance oxygen transport from shoot base to root tips of plants in waterlogged soil.

Effect of Carex rostrata on seasonal and interannual variability in peatland methane emissions [PDF]

, 2014
Peatlands are a large natural source of atmospheric methane (CH4), and the sedge Carex rostrata plays a critical role in the production, oxidation, and transport of CH4 in these systems.

Secondary Aerenchyma Formation in Hypocotyl in Summer Leguminous Crops.

Japanese Journal of Crop Science, 2000
The secondary aerenchyma formation in hypocotyl just below the soil surface was investigated by using the young seedings of wild soybean and six summer leguminous crops grown under upland and excessive moisture conditions for 14 days. Under the upland conditions, secondary aerenchyma was scarcely observed in any species.

Graminoids Increase Greenhouse Gas Emissions From Thawed Permafrost at the End of the Growing Season

Global Change Biology, Volume 32, Issue 3, March 2026.
Field study investigating whether and to which degree graminoids further reduce soil redox and lead to more greenhouse gas emissions from thawing permafrost soil on top of hydrology and anoxia effects. Graminoids, thus, contribute to thawed permafrost soils turning to C sources rather than sinks toward the end of the growing season.

Increased CH4 Oxidation in Arctic Tundra Ecosystems Caused by Vegetation‐Mediated Soil Drying

Global Change Biology, Volume 32, Issue 3, March 2026.
In a warmer Arctic, vegetation changes can play a critical role in methane dynamics. Our results indicate that taller vegetation, shifts in species composition, and warmer air temperatures enhance soil aeration by increasing evapotranspiration, thereby promoting methane oxidation in surface soils.

Variation in the plant-mediated methane transport and its importance for methane emission from intact wetland peat mesocosms [PDF]

, 2013
Aims and Methods Vascular plants are known to influence the production, transport and oxidation of methane in wetland soils, but these processes are not well understood.

Accession‐Specific Responses to Submergence Stress in Lotus japonicus: Implications for Legume Climate Resilience

Journal of Agronomy and Crop Science, Volume 212, Issue 2, March 2026.
ABSTRACT Flooding is a major abiotic stress that limits legume productivity and ecological resilience. Identifying variation in submergence tolerance among legume accessions is critical for developing climate‐resilient cultivars. This study investigated phenotypic and physiological responses to complete submergence in nine Lotus japonicus accessions ...

Effects of different water regimes on the anatomical characteristics of roots of grasses promising for revegetation of areas surrounding hydroelectric reservoir Efeitos de diferentes regimes hídricos sobre as características anatômicas de raízes de gramíneas promissoras para revegetação de áreas marginais a reservatórios hidrelétricos

Ciência e Agrotecnologia, 2003
The objective of this study was to evaluate the effect of different water regimes on some aspects of root anatomy of three grasses: Echinochloa pyramidalis (canarana), Setaria anceps (setária) and Paspalum paniculatum (paspalo).

Epidermal Cell Dynamics Regulates Rice Lamina Joint Morphogenesis and Leaf Angle Formation through OsZHD1 and OsZHD2 Regulation

Advanced Science, Volume 13, Issue 9, 13 February 2026.
The lamina joint determines leaf angle and plant architecture. Xu et al. establish a live‐imaging system for the rice lamina joint and reveal that asymmetric epidermal cell elongation and division between the lateral and medial edges drive leaf angle formation.
