Physiological Responses of Typical Wetland Plants Following Flooding Process—From an Eco-Hydrological Model Perspective

Frontiers in Ecology and Evolution, 2022
Anaerobics increase resistance to gas transport and microbial activity in flooded soils. This may result in the presence of aerenchyma in the roots of some wetland plants.

Morpho‐Anatomical and HPTLC Investigations of Lysimachia nummularia L. (Primulaceae) Grown in Switzerland

Microscopy Research and Technique, EarlyView.
This research provides a complete morphoanatomical description of Lysimachia nummularia, as well as a HPTLC profile. Standard techniques of light and scanning electron microscopies, as well as standard techniques of HPTLC, were used. ABSTRACT Primulaceae are distributed all over the world, encompassing around 2590 species.

Aerenchyma Carbon Dioxide Can Be Assimilated in Typha Iatifolia L. Leaves [PDF]

Plant Physiology, 1994
Leaf structural characteristics and gas-exchange measurements were used to determine whether photosynthetic tissue of Typha Iatifolia L. (cattail) utilized CO2 from the aerenchyma gas spaces, part of an internal pathway for gas transport in this wetland species. The partial pressure of CO2 (pCO2) in these aerenchyma gas spaces can be more than 10 times

Plant responses to limited aeration: Advances and future challenges

Plant Direct, 2023
Limited aeration that is caused by tissue geometry, diffusion barriers, high elevation, or a flooding event poses major challenges to plants and is often, but not exclusively, associated with low oxygen.

Mechanical Strength: An Unrecognised Target in the Genetic Improvement of Crops

Plant Biotechnology Journal, EarlyView.
ABSTRACT Leaf angle (LA) is a crucial agronomic trait influencing planting density and crop yield. Previous research highlighted the importance of cellular variations in the ligular region for determining LA, but the underlying regulatory mechanisms remain unclear.

Roles of auxin and ethylene in aerenchyma formation in sugarcane roots [PDF]

Plant Signaling & Behavior, 2018
Although the cross-talk between auxin and ethylene has been described during plant development, the role played by auxin upon gene expression during aerenchyma formation is poorly understood. Root aerenchyma formation results from the opening of gas spaces in the cortex.

Root Structural and Metabolic Plasticity Confers Tolerance to Salinity in Wild Barley Species Grown Under Waterlogging

Plant, Cell &Environment, EarlyView.
ABSTRACT Salinity combined with waterlogging is a major abiotic stress that severely limits crop growth and yield. We investigated species‐specific adaptations to salinity under constant waterlogging conditions in the wild halophytic barleys Hordeum marinum and H. glaucum, compared with the cultivated H. vulgare.

Root cortical aerenchyma inhibits radial nutrient transport in maize (Zea mays) [PDF]

Annals of Botany, 2013
Formation of root cortical aerenchyma (RCA) can be induced by nutrient deficiency. In species adapted to aerobic soil conditions, this response is adaptive by reducing root maintenance requirements, thereby permitting greater soil exploration. One trade-off of RCA formation may be reduced radial transport of nutrients due to reduction in living ...

Response to Waterlogging Stress in Wild and Domesticated Accessions of Timothy (Phleum pratense) and Its Relatives P. alpinum and P. nodosum

Plants, 2023
Timothy (Phleum pratense) is a cool-season perennial forage grass widely grown for silage and hay production in northern regions. Climate change scenarios predict an increase in extreme weather events with fluctuating periods of high rainfall, requiring ...

Root and microbial contributions to anoxic microsite formation in the rhizosphere: a microfluidic approach

New Phytologist, Volume 250, Issue 5, Page 3486-3498, June 2026.
Summary Plant root‐associated anoxic microsites may influence the fate of nutrients and contaminants in the rhizosphere, but their dynamics remain relatively unknown. To examine the formation of root‐induced anoxic microsites over space and time, we use microfluidic devices integrated with transparent, planar oxygen sensors in a wheat (Triticum ...
