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 ...
