Gas Transport and Exchange through Wetland Plant Aerenchyma
2013Aerenchyma, the large airspaces in aquatic plants, is a rapid gas transport pathway between atmosphere and soil in wetlands. Oxygen transport aerates belowground tissue and oxidizes rhizosphere soil, an important process in wetland biogeochemistry. Most plant O2 transport occurs by diffusion, and the major challenge for its accurate measurement is ...

Programmed Cell Death and Aerenchyma Formation Under Hypoxia
2010This chapter describes the sequence of events leading to lysigenous aerenchyma formation in the roots of wetland and dryland plants. The events start from various stimuli that can induce cells to go through programmed cell death (PCD) in mid-cortical regions of the root: lack of oxygen (hypoxia), nitrogen, phosphorus or sulphur starvation and ...

Development of aerenchyma in roots and rhizomes of Carex rostrata (Cyperaceae)
Nordic Journal of Botany, 1992Aerenchyma development in Carex rostrata was studied using light and scanning electron microscopy. Specimens were collected at two locations in southern Finland. Examination showed the beginning of aerenchyma development in the cortex of roots at the distance of 30–45 mm from the apex and it was fully developed at 75–90 mm from the apex.

Regulation of Aerenchyma Formation in Roots and Shoots by Oxygen and Ethylene
1989Excess water, especially around roots and the lover parts of the shoot, is a frequent cause of abnormally slow rates of gaseous exchange between plants and their environment (Armstrong, 1979) in a wide range of habitats that embrace tidal estuaries, river and lake margins, swamp and marshland, poorly drained agricultural land, rice paddies and ...

Iron tolerance and the role of aerenchyma in wetland plants
1981The relative iron (II) tolerance of a range of wetland plants was determined and compared with some species characteristic of well drained soils. A wide range of tolerance occurred amongst the wetland species but they were generally more tolerant than those from well drained soils.
