Changes of free polyamines in the leaves and stems of ‘Kinnow’ mandarin tree as affected by alternate bearing
In order to investigate the seasonal changes and the possible role of the free polyamines in the leaves and stems on the alternate bearing habit of the ‘Kinnow’ mandarin (Citrus reticulata Blanco) trees, a comparative study was conducted to analyze the levels of free polyamines (putrescine, spermidine and spermine) in the leaves and stems tissues of “on” and &ldquo...
متن کاملProteases of Senescing Oat Leaves
Two proteases isolated from senescent oat (Avens saiva) leaves have been subjected to further study. One of these, an acid protease active at pH 4.2, is inhibited by phenylmethylsulfonyl fluoride (PMSF) but not by iodoacetamide (lAc). The other, active at pH 6.6, is inhibited by both PMSF and IAc. These results, together with previously reported evidence that mercaptoethanol stimulates the acti...
متن کاملSenescing sexual ornaments recover after a sabbatical.
Somatic deterioration in ageing animals may arise from allocation of resources to reproduction at the expense of repair and maintenance. Thus, accumulated reproductive effort is likely to progressively limit the expression of sexual ornaments at older ages. We analysed the effect of age and reproductive effort on the sexual attractiveness (foot colour) of male blue-footed boobies. Using a long-...
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...
