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.

Brachypodium SPEECHLESS2 Promoter Drives Expression of a Synthetic EPF to Reduce Stomatal Density in Sugarcane Without Pleiotropic Effects

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2372-2384, April 2026.
ABSTRACT Stomata are microscopic pores that regulate the exchange of CO2 and water vapour, making them a major target for engineering plants with improved intrinsic water use efficiency (iWUE). Proof‐of‐concept studies have demonstrated the potential to increase iWUE by reducing stomatal density (SD) and stomatal conductance (gsw) by ubiquitously ...

Linking Superoxide Production and Scavenging in Plant Development

Plant, Cell &Environment, Volume 49, Issue 4, Page 2048-2068, April 2026.
ABSTRACT Due to their strong oxidizing potential, rapid membrane permeability, and high reactivity, reactive oxygen species (ROS) play essential roles in plant development and stress responses. Superoxide (O2•‐) is a primary product of molecular oxygen reduction and a crucial source of hydrogen peroxide, representing a ROS species of substantial ...

Characterizing the causes and consequences of calcium oxalate crystal presence in Vitis riparia

American Journal of Botany, Volume 113, Issue 3, March 2026.
Abstract Premise Calcium oxalate biomineralization in plants is phylogenetically widespread and morphologically diverse, but the function of these inorganic crystals is an area of active debate. The variety of environmental conditions that produce the crystals, as well as the inconsistent evidence that they provide antiherbivore defense across plant ...

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.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Aspects of an experimental study on root aerenchyma development and the ecological implications thereof

Bothalia: African Biodiversity & Conservation, 1983
Anaerobic conditions induced cortical aerenchyma in maize roots cultivated in water culture. Similar results were obtained by growing the plants in nitrate and phosphate deficient solutions but the cavitation was more severe when conditions were ...

Nitrogen application rates mediate rice cooking quality by interfering with root anatomical and senescence physiological traits

Plant, Soil and Environment
Nitrogen fertiliser is a key determinant of rice yield and grain quality; however, the synergistic mechanisms through which nitrogen regulates root anatomical structure, physiological traits, and cooking quality in rice varieties with different eating ...

Rooting System of Rice Cultivated under System of Rice Intensification (SRI) Method which Improving Rice Yield

Hayati Journal of Biosciences, 2018
The development of plant roots is known to play a very important role in the uptake of water and nutrients by rice plants. However, there are few studies on what changes, if any, are induced in the rooting systems of rice plants under System of Rice ...

AERENCHYMA FORMATION IN MAIZE PLANTS UNDER PHOSPHORUS DEFICIENCY

Revista Brasileira de Milho e Sorgo, 2006
The objective of this work was to verify, under phosphorus stress (P), possible alterations to the root anatomy of maize inbred line A188 and its transgenic version having the genetic construction AtPT2::GUS. AtPT2::GUS plants were used as a positive control to validate the P stress, once this promoter directs GUS reporter gene expression only to the ...
