AERENCHYMA DEVELOPMENT IN WATERLOGGED PLANTS
American Journal of Botany, 1980Aerenchyma development in waterlogged Helianthus annuus, Lycopersicon esculentum, and Salix fragilis was studied. More than half of the root cortical tissue sometimes became an air cavity in willow roots which developed in water. There was no cortical aerenchyma in the terminal portion, but more advanced aerenchyma developed towards the base of the ...

Programmed cell death and aerenchyma formation in roots
Trends in Plant Science, 2000Lysigenous aerenchyma contributes to the ability of plants to tolerate low-oxygen soil environments, by providing an internal aeration system for the transfer of oxygen from the shoot. However, aerenchyma formation requires the death of cells in the root cortex.

Physiological roles for aerenchyma in phosphorus-stressed roots
Functional Plant Biology, 2003Low phosphorus availability induces the formation of cortical aerenchyma in roots. The adaptive significance of this response is unknown. We hypothesized that aerenchyma may be helpful to low-phosphorus plants by reducing root respiratory and phosphorus requirements, thereby increasing the metabolic efficiency of soil exploration.

New Phytologist, 2003
SummaryAerenchyma – tissue containing enlarged gas spaces – occurs in many plants. It is formed either as part of normal development, or in response to stress (e.g. hypoxia). Two mechanisms of aerenchyma formation have been described; schizogeny, in which development results in the cell separation and lysigeny, in which cells die to create the gas ...

Aerenchyma formation in crop species: A review
Field Crops Research, 2013Flooding is a major problem in many crop areas around the world. However, many wetland plant species can expand their roots into flooded soils because of the presence of longitudinal aerenchyma channels that facilitate oxygen diffusion from the shoots to the root tips.

Aerenchyma Formation in Plants
2013Aerenchyma enhances internal aeration between, and within, shoots and roots. Aerenchyma formation is therefore important for the adaptation of plants in environments with excess water, such as plants with roots in waterlogged soils or submerged shoots.

DIAPHRAGMS AND AERENCHYMA IN SCIRPUS VALIDUS
American Journal of Botany, 1971After the short‐lived apical meristem ceases activity, a basal intercalary meristem produces all new tissues in the aerial internode of Scirpus validus Vahl. These include extensions of the original vascular system and of the original partitioning walls as well as new vascular bundles and new walls which are produced in a predictable pattern ...

HIGH CARBON DIOXIDE CONCENTRATIONS IN AERENCHYMA OF TYPHA LATIFOLIA
American Journal of Botany, 1992Diurnal and seasonal patterns of CO2 concentration ([CO2]) in leaf gas spaces were measured to better understand the relationship of sediment‐derived CO2 to photosynthesis in the emergent wetland species, Typha latifolia L. (cattail). Leaf [CO2] was above 2,000 μl/liter at dawn on all but the first sampling date.

Enhancement of porosity and aerenchyma formation in nitrogen-deficient rice roots
Plant Science, 2014Root aerenchyma provides oxygen from plant shoots to roots. In upland crops, aerenchyma formation is induced mainly by oxygen or nutrient deficiency. Unlike upland crops, rice forms root aerenchyma constitutively and also inductively in response to oxygen deficiency.
