Plants, like animals, are obligate aerobes, but due to their inability to move, have evolved adaptation mechanisms that enable them to survive short periods of low oxygen supply, such as those occurring after heavy rain or flooding. Crop plants are often grown on soils subject to waterlogging and many are sensitive to waterlogging of the root zone. The combination of unfavourable weather condit...

The evergreen Nothofagus betuloides and deciduous Nothofagus pumilio live close together in Tierra del Fuego. The fact that these two species rarely form mixed forests suggests that the soil factor can contribute to the distribution of two species on a local scale. Most of these forests are undisturbed; therefore, soil characteristics may reflect both the influence of the species and of the dom...

To investigate the mechanism on waterlogging tolerance in Brassica napus, 12 B. napus cultivars with different waterlogging tolerance were used in the research and Waterlogging Tolerance Index (WTI) was calculated by multiplying relative percentage germination and the relative seedling height. The results indicated that Lactate Dehydrogenase (LDH) enzyme activity rapidly increased at 24 h after...

A previous report showed that both Pyruvatedecarboxylase (PDC) genes were significantly upregulated in kiwifruit after waterlogging treatment using Illumina sequencing technology, and that the kiwifruit AdPDC1 gene was required during waterlogging, but might not be required during other environmental stresses. Here, the function of another PDC gene, named AdPDC2, was analyzed. The expression of...

More than one third of the world’s irrigated areas suffer occasional or more frequent waterlogging (Donmann and Houston, 1967). Waterlogging has been shown to limit wheat yields in many regions of the world; an area estimated at 10 million ha is waterlogged each year in developing countries (Sayre et al., 1994). Waterlogging occurs when rainfall or irrigation water collects on the soil surface ...

Radiata pine (Pinus radiata D. Don) and Douglas fir (Pseudotsuga menziesii (Mirb.) Franco.) seedlings were subjected to waterlogging periods of 1, 2, 4, 3, and 16 weeks. Phosphorus-32 uptake and succinic dehydrogenase activity of waterlogged mycorrhizas were measured and compared with non-waterlogged mycorrhizas. After 2 weeks of waterlogging Douglas fir mycorrhizas absorbed less P than control...

Waterlogging and salinity are two major abiotic stresses that hamper crop production world-wide resulting in multibillion losses. Plant abiotic stress tolerance is conferred by many interrelated mechanisms. Amongst these, the cell's ability to maintain membrane potential (MP) is considered to be amongst the most crucial traits, a positive relationship between the ability of plants to maintain h...
