Response and adaptation by plants to flooding stress. | Semantic Scholar (2024)

This update reviews the current comprehension of the metabolic, physiological and morphological responses and adaptations of plants to soil waterlogging and suggests efficient use of carbohydrates may discriminate between tolerant and intolerant species.

This review summarizes the major findings from proteomic studies that have examined flooding stress-response mechanisms in important crop species, and protein abundance changes and their significance during post-flooding recovery are discussed.

The present review summarizes physiological and molecular features of waterlogging tolerance of trees; the focus is on carbon metabolism in both, leaves and roots of trees.

An overview of the articles is provided, with attempts to summarize how recent research results are being used to produce varieties of crop plants with greater flooding tolerance, notably in rice.

It is vital that biotechnological and breeding efforts to harness mechanisms that facilitate the maintenance of productivity in response to drought, flooding, and heat stress are accelerated in the coming decade.

There was no significant interaction between inbreeding and the intensity of any stress type, and ID was not higher under novel than under familiar stresses, and phenotypic plasticity in biomass allocation, leaf functional traits and in root nodulation of the legume to the various stress treatments was not influenced by inbreeding.

Results show that P. fasciculatum is more resistant to flooding than B. brizantha, with a high production of adventitious roots, which probably helped the species to survive the period of hypoxia.

The capacity to elongate is an important selective trait in field distribution patterns of plants in flood-prone environments and may be more widely applicable in ecological studies that aim to understand the functional relationship between plant traits and species distributions along environmental gradients.

Light increases the survival of terrestrial plants under water, indicating that photosynthesis commonly occurs under these submerged conditions, and thereby alleviates the adverse effects of flooding.

DNA markers for a major QTL for tolerance are shown to be potentially useful in breeding programmes designed to improve submergence tolerance, and recent progress achieved using linkage mapping to locate quantitative traits loci for tolerance inherited from a submergence-tolerant cultivar FR13A is reviewed.

It is shown that acclimation to anoxia in plants involves integration of a set of sophisticated characteristics, as a consequence of which the habitat within the anoxic cell is a very different world to that of the aerobic cell.

The pattern of transcript accumulation of a R. palustris alpha-expansin gene correlated with the pattern of petiole elongation upon submergence, indicating a significant increase of the in vitro cell wall extensibility in submerged petioles.

This review addresses the extent of knowledge on the plant ecology of these wetlands and covers: the relationships between the climate and the hydrological regime on the floodplain; the vegetation patterns, succession and adaptation; and primary production.

The review highlights recent work on the processes that sense oxygen deficiency and ethylene signals, subsequent transduction processes which initiate cell death, and steps in protoplast and wall degeneration that create the intercellular voids.

The foundations of a marker-assisted scheme for introducing submergence tolerance into agriculturally desirable cultivars of rice are established and this work exploits naturally occurring differences between certain rice lines in their tolerance to submergence.
