A pleiotropic “stretch” phenotype is associated with metaxylem vessel element length, axial hydraulic conductance, root elongation, water utilization, and drought adaptation in maize

Crop Science, Volume 66, Issue 3, May/June 2026.
Abstract We tested the hypothesis that metaxylem phenotypes influence drought adaptation in maize (Zea mays L.) through in silico modeling and empirical studies under water deficit in controlled environments and in the field. Substantial genotypic variation for metaxylem vessel element length (MVEL) was observed. Longer MVEL was correlated with reduced

Image_4_Immunoprofiling of Cell Wall Carbohydrate Modifications During Flooding-Induced Aerenchyma Formation in Fabaceae Roots.tif

, 2020
Understanding plant adaptation mechanisms to prolonged water immersion provides options for genetic modification of existing crops to create cultivars more tolerant of periodic flooding. An important advancement in understanding flooding adaptation would

Development of schizogenous intercellular spaces in plants

Frontiers in Plant Science, 2015
Gas exchange is essential for multicellular organisms. In contrast to the circulatory systems of animals, land plants have tissues with intercellular spaces (ICSs), called aerenchyma, that are critical for efficient gas exchange.

Printed PHBV‐Based Sensors as a Real‐Time Proxy for Soil Microbial Decomposer Activity During Drought and Flood Recovery

European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
Novel sensors that can be made cheaply (1) are deployed in multiple pots (2). These have either nutrient‐poor soil with a biodiverse community or arable soil with wheat plants which are subjected to droughts and flood stresses (2). We show the sensors can track decomposition through time at high temporal resolution while and after the pots are stressed,

Low Climate Benefit of Nordic Coastal Marshes: Site Conditions Outweigh Grazing Effects and Shape Trade‐Offs Between Carbon Storage and Its Stability

Global Change Biology, Volume 32, Issue 5, May 2026.
Conceptual diagram of soil carbon cycling across climatic and environmental gradients in Nordic marshes and grazing effect. Denmark's warmer climate, high nutrient inputs, elevated salinity, and sandy soils promote rapid microbial decomposition of predominantly labile and root‐derived OC, driving high CO2 emissions and relatively high although unstable

Aerenchyma formation and recovery from hypoxia of the flooded root system of nodulated soybean

, 2015
Background and Aims Flooding results in hypoxia of the root system to which N-2 fixation of nodulated roots can be especially sensitive. Morphological adaptions, such as aerenchyma formation, can facilitate the diffusion of oxygen to the hypoxic tissues.

Multi‐Decadal Dynamics of Wetland Methane Emissions Revealed by Knowledge‐Guided Machine Learning

Global Change Biology, Volume 32, Issue 5, May 2026.
Eddy covariance data for wetland CH4 emissions are fragmented, restricting the assessment of their long‐term dynamics. This study developed a knowledge‐guided machine‐learning framework that integrates field observations with biogeochemical principles to reliably reconstruct historical methane fluxes.

The function of the aerenchyma in arborescent lycopsids: evidence of an unfamiliar metabolic strategy [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2010
Abstract Most species of the modern family Isoëtaceae (Quillworts) some other modern hydrophytes, use a metabolic pathway for carbon fixation that involves uptake of sedimentary carbon and enrichment of CO2 in internal gas spaces as a carbon-concentrating mechanism.

Growth, Photosynthesis and Root Metabolome Responses to Graded Hypoxia in Contrasting Rice Cultivars

Journal of Agronomy and Crop Science, Volume 212, Issue 3, May 2026.
ABSTRACT Rice is an economically important crop and a staple food for a large proportion of the world's population. Although rice is generally adapted to flooded soils, cultivars may differ in their responses to reduced oxygen availability. Here, we evaluated growth, physiological performance and organ‐specific metabolic profiles of two rice cultivars ...

Evolution of aerenchyma formation in a maize breeding program. [PDF]

, 2016
Approximately 28 million hectares of intermittently flooded land with agricultural potential in Brazil could be used for rice crop rotation to increase production.
