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.

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

EFFECT OF ETHYLENE ON AERENCHYMA DEVELOPMENT
American Journal of Botany, 1981When applied to a part of stem or basal part of stem and root system, 1 ppm ethylene induced lysigenous aerenchyma development in the stem cortex of Helianthus annuus, Lycopersicon esculentum, and Phaseolus vulgaris. Local application of ethylene to a part of stem significantly increased the activity of cellulase in that part of stem in the above three

A Re‐examination of the Functional Significance of Aerenchyma
Physiologia Plantarum, 1972AbstractModel roots of known length and internal porosity were assayed for ROL (radial oxygen loss) by the cylindrical Pt electrode technique and a series of curves were obtained which express the inter‐relationships between ROL and diffusion path length over a wide range of internal porosity levels.The results indicate that internal porosity can exert

ROLE OF CELLULASE IN AERENCHYMA DEVELOPMENT IN SUNFLOWER
American Journal of Botany, 1979A hypothesis that ethylene causes aerenchyma development in waterlogged plants through increased cellulase activity was tested with sunflower, Helianthus annuus L. Treatment with commercial cellulase induced aerenchyma development in sunflower stem sections.

Aerenchyma Formation and Methane and Oxygen Exchange in Rice
Soil Science Society of America Journal, 1993Abstract Limited information exists on the direct link between the intensity of soil reduction or anaerobiosis and gas exchange in rice ( Oryza sativa L.). A laboratory experiment was conducted to determine the extent to which specific levels of soil redox potential (Eh ...

The Parichnos Problem and the Function of Aerenchyma in the Lycopsida
Bulletin of the Peabody Museum of Natural History, 2014Abstract The term parichnos, coined in 1891, has been used since then with more or less precision to describe a morphological or anatomical feature in several taxa of fossilized lycopsids. The parichnos is a tissue system found surrounding or accompanying the (vascular) leaf traces on their paths from the stele to the leaves.

CO2 and O2 transport in the aerenchyma of Cyperus papyrus L.
Aquatic Botany, 1995Abstract Cyperus papyrus L. (papyrus) is an emergent wetland species with C 4 photosynthesis. Culms of papyrus possess numerous large intercellular air cavities and functional ‘Kranz’ chlorenchyma which are involved in CO 2 recycling in the culm. In darkness, the CO 2 concentration in the culms increased to 74 times that of the ambient air.
