Halophytes As Bioenergy Crops
Shrinking arable land due to soil salinization and, depleting fresh water resources pose serious worldwide constraints to crop productivity. A vision of using plant feedstock for biofuel production can only be realized if we can identify alternate species that can be grown on saline soils and therefore, would not compete for the resources required for conventional agriculture. Halophytes have r...
متن کاملSalt Tolerance and Crop Potential of Halophytes
Although they represent only 2% of terrestrial plant species, halophytes are present in about half the higher plant families and represent a wide diversity of plant forms. Despite their polyphyletic origins, halophytes appear to have evolved the same basic method of osmotic adjustment: accumulation of inorganic salts, mainly NaCl, in the vacuole and accumulation of organic solutes in the cytopl...
متن کاملPolyamines in inflammation
esults on page 257 by Soulet and Rivest implicate polyamines in controlling immune responses in the brain. Their results suggest that polyamine synthesis, if left unchecked, can cause damaging inflammatory responses reminiscent of neurodegenerative disorders. Recognition of bacterial and viral pathogens by microglial cells, the brain’s equivalent of macrophages, elicits a cascade of gene expres...
متن کاملPolyamines in intestinal growth.
The total cellular mass of the small intestine is well controlled and can adapt, with hypo- or hyperplasia, to a wide variety of stimuli. Luminal nutrients, hormonal factors and pancreatic and biliary secretions have all been implicated in the regulation of intestinal mucosal growth. The polyamines (putrescine, spermidine and spermine) and the key enzyme controlling their synthesis (ornithine d...
متن کاملPolyamines in living organisms
Natural polyamines, putrescine, spermidine and spermine are ubiquitous cell components essential for normal cellular functions and growth. Chemically these compounds are very simple organic aliphatic cations and fully protonated under physiological conditions. There is a strong correlation between proliferation rate of the cells and their polyamine contents. Adjustments of intracellular concent...
