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

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.

Programmed cell death during aerenchyma formation in Typha angustifolia leaves
Aquatic Botany, 2014Abstract To facilitate gas exchange, some plants produce specialized air cavities called aerenchyma. To determine how the aerenchyma is formed, we conducted serial experimental observations and tests. Here we provide evidence that aerenchyma is formed in Typha angustifolia leaves through cell lysis in which programmed cell death (PCD) is involved ...

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 ...

Aerenchyma formation in roots of four banana (Musa spp.) cultivars
Scientia Horticulturae, 1999Abstract We assessed the impact of aeration and stagnation of the rooting medium on aerenchyma development and root porosity (total gas spaces) in four banana cultivars (cvs) using plantlets from tissue culture and from suckers. Aerenchyma formation in nodal roots of banana was expressed as percentage root porosity and cross sectional area of ...

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 ...

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

The ethylene receptor regulates Typha angustifolia leaf aerenchyma morphogenesis and cell fate
Planta, 2019Ethylene receptor is crucial for PCD and aerenchyma formation in Typha angustifolia leaves. Not only does it receive and deliver the ethylene signal, but it probably can determine the cell fate during aerenchyma morphogenesis, which is due to the receptor expression quantity.

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 ...
