Plant responses to limited aeration: Advances and future challenges
Plant Direct, 2023 Limited aeration that is caused by tissue geometry, diffusion barriers, high elevation, or a flooding event poses major challenges to plants and is often, but not exclusively, associated with low oxygen.

Plant Biotechnology Journal, EarlyView.ABSTRACT Rice has developed an efficient system for manganese (Mn) uptake, mediated by two distinct transporters, OsNramp5 and OsMTP9. These transporters exhibit polar localization at the root exodermis and endodermis; however, the mechanisms underlying their polar localization and their role in Mn uptake remain unclear.

Cell wall changes during the formation of aerenchyma in sugarcane roots [PDF]
Annals of Botany, 2017 Aerenchyma develops in different plant organs and leads to the formation of intercellular spaces that can be used by the plant to transport volatile substances. Little is known about the role of cell walls in this process, although the mechanism of aerenchyma formation is known to involve programmed cell death and some cell wall modifications.

Plant, Cell &Environment, EarlyView.ABSTRACT Salinity combined with waterlogging is a major abiotic stress that severely limits crop growth and yield. We investigated species‐specific adaptations to salinity under constant waterlogging conditions in the wild halophytic barleys Hordeum marinum and H. glaucum, compared with the cultivated H. vulgare.

Plant, Cell &Environment, EarlyView.ABSTRACT Cereal crops are fundamental to global food security, but their production is increasingly challenged by rising demand and the unpredictable impacts of climate change. Among the most limiting and interdependent resources sustaining yields are nitrogen and water.

Aerenchyma Development in the Freshwater Marsh Species Sagittaria Lancifolia L.
, 1997 Aerenchyma tissue consists of gas channels that provide a pathway for O$\sb2$ transport to waterlogged roots. Aerenchyma gas spaces are formed by cell separation or cell lysis during development.
