Inundation that gives rise to soil flooding, or more complete submergence, is the most
common environmental cause of oxygen deprivation for vascular plants. Species differ …

These topics are reviewed under the headings: sources of ethylene (entrapment by water,
biosynthesis as related to oxygen supply, and production by soil); physiological responses of …

Rice plants are much damaged by several days of total submergence. The effect can be a
serious problem for rice farmers in the rainfed lowlands of Asia, and runs contrary to a …

Stress on plants imposed by flooding of the soil and deeper submergence constitutes one of
the major abiotic constraints on growth, species' distribution and agricultural productivity. …

Enhanced development of gas-spaces beyond that due to the partial cell separation normally
found in ground parenchymas and their derivatives creates tissue commonly termed “…

The roots and stem base of intact, 10 day old maize (Zea mays L. cv. LG11) plants, grown in
nutrient solution, were continuously aerated either with ethylene (5 μl l -1 ) in air or with air …

It has been estimated that wetlands occupy approximately 6% of the earth’s land surfaces (Maltby
1991). They comprise fresh, brackish and salt-water marshes, inland and coastal …

Research on the mechanisms that underlie plant responses to flooding and the capacity of
some species or cultivars to tolerate flooding is reviewed. Effects of flooding on the roots, the …

The sigma-1 receptor is widely distributed in the central nervous system and periphery.
Originally mischaracterized as an opioid receptor, the sigma-1 receptor binds a vast number of …

The sigma receptor is a novel protein that mediates the modulation of ion channels by
psychotropic drugs through a unique transduction mechanism depending neither on G proteins …
