Oxic microzones and radial oxygen loss from roots of Zostera marina (2005, background): “…in agar showed that the ROL was variable along the root axis in different wetland species (e.g. Armstrong 1971 [Oryza spp.], Connell et al. 1999 [Halophila ovalis], Armstrong et al. 2000 [Phragmites australis]), with substantial ROL only occurring close to the root tips and the fine lateral roots.”
Waterlogging tolerance in the tribe Triticeae: the adventitious roots of Critesion marinum have a relatively high porosity and a barrier to radial oxygen loss (2001, background): “(Armstrong et al. 2000).”
Oxygen Movement in Seagrasses (2007, background): “To ensure sufficient oxygen supply along the length of roots to the root apex, the radial loss from root surfaces of seagrasses and other aquatic plants seems to decline substantially with increasing distance to root tips (Fig. 6; Armstrong, 1971; Connell et al., 1999; Armstrong et al., 2000; McDo”
Role of Plants in a Constructed Wetland: Current and New Perspectives (2013, background): “Oxygenation by roots has been shown to have a significant impact on important mechanisms of wastewater treatment in CWs, including influence on redox potential [61], which is critical in determining nitrogen fate, oxidation of some phytotoxins [56], and enhancement of microbial activity [62].”
Suberin lamella development in maize seedling roots grown in aerated and stagnant conditions (2005, background): “Co-ordination of the lateral roots, cortical bridges and unmodified exodermis has been observed in Phragmites (Justin & Armstrong 1987; Armstrong et al. 2000; Soukup, Votrubová & í ková 2002), and it is believed that the unsuberized exodermal ‘windows’ provide a low resistance point of egress for th”
Oxygen dynamics in the rhizosphere of Zostera marina: A two‐dimensional planar optode study (2006, background): “Our present knowledge on the anatomical basis for the barriers against ROL in rooted macrophytes is very limited, but it is probably related to densely packed cells, suberin deposits, and lignification of the outer cell layers (Sorrel and Boon 1994; Barnabas 1996; Armstrong et al. 2000).”
Rhizosphere: biophysics, biogeochemistry and ecological relevance (2009, background): “2008), possibly up to a few mm from the root surface (Begg et al. 1994; Armstrong et al. 2000).”
Similarity and diversity in adventitious root anatomy as related to root aeration among a range of wetland and dryland grass species (2002, background): “Although the physical basis of the barrier to ROL was not evaluated in the present study, traits such as lignification and/or suberization the epidermal-hypodermal cylinder (Armstrong & Armstrong 1988; Armstrong et al. 2000) or the dense arrangement of cells in the epidermalhypodermal cylinder (Conn”
Long-distance transport of gases in plants: a perspective on internal aeration and radial oxygen loss from roots (2003, background): “water, nutrients, soil toxins, soilderived gases) between roots and soil would be determined by the anatomical and chemical nature of the barrier (Beckett, Armstrong & Armstrong J 2001b), as well as the possibility of ‘passage areas’ (Armstrong et al. 2000).”
Water Flow in the Roots of Crop Species: The Influence of Root Structure, Aquaporin Activity, and Waterlogging (2007, background): “The nature of the barrier is unresolved but may involve tightly packed cells and wall modifications such as thickening and lignification (Armstrong et al., 2000).”
