Soluble and microsomal glutatione S-transferase activities in pea seedlings (Pisum sativum L.).

Epicotyl and primary leaves of pea seedlings (Pisum sativum L., var. Alaska) were found to contain soluble and microsomal enzymes catalyzing the addit...

Effect of exogenous lead on growth and carbon metabolism of pea (Pisum sativum L) seedlings.
The present study investigated the effect of exogenous lead (Pb) on seedling growth, carbohydrate composition and vital enzymes of sucrose metabolism, starch degradation, pentose phosphate pathway and glycolysis in pea seedlings. With 0.5 mM Pb, redu

Dehydration induces expression of GALACTINOL SYNTHASE and RAFFINOSE SYNTHASE in seedlings of pea (Pisum sativum L.).
The exposition of 7-day-old pea seedlings to dehydration induced sudden changes in the concentration of monosaccharides and sucrose in epicotyl and roots tissues. During 24h of dehydration, the concentration of glucose and, to a lesser extent, fructo

Flowering time adaption in Swedish landrace pea (Pisum sativum L.).
Cultivated crops have repeatedly faced new climatic conditions while spreading from their site of origin. In Sweden, at the northernmost fringe of Europe, extreme conditions with temperature-limited growth seasons and long days require specific adapt

Transport of exogenous auxin in two-branched dwarf pea seedlings (Pisum sativum L.) : Some implications for polarity and apical dominance.
Dwarf pea plants bearing two cotyledonary shoots were obtained by removing the epicotyl shortly after germination, and the patterns of distribution of (14)C in these plants was investigated following the application of [(14)C]IAA to the apex of one s

Accumulation of (14)C from exogenous labelled auxin in lateral root primordia of intact pea seedlings (Pisum sativum L.).
When [(14)C]indol-3yl-acetic acid was applied to the apical bud of 5-day old dwarf pea seedlings which possessed unbranched primary roots, a small amount of (14)C was transported into the root system at a velocity of 11-14 mm h(-1). Most of the (14)C

Development of chromatin-bound and soluble DNA polymerase activities during germination of Pisum sativum L.
Chromatin-bound and soluble DNA-dependent DNA polymerases were assayed in the embryonic axes of germinating peas (Pisum sativum L.). Activities of both enzymes increased markedly during germination, prior to the onset of net DNA synthesis. The activi

Possible control sites of polysaccharide synthesis during cell growth and wall expansion of pea seedlings (Pisum sativum L.).
The activities of the enzymes of uridine diphosphate sugar interconversions (UDP-D-glucose 4-epimerase, UDP-D-glucuronate 4-epimerase, UDP-D-xylose 4-epimerase, UDP-D-glucose dehydrogenase and UDP-D-glucuronate decarboxylase) were measured by using e

Evidence for carrier-mediated transport of L-leucine into isolated pea (Pisum sativum L.) chloroplasts.
The uptake of leucine into isolated, intact, pea chloroplasts was investigated using the silicone oil centrifugation technique. The internal: external ratio of leucine exceeded unity at low external leucine concentrations. Uptake of leucine at differ

Characterization of proanthocyanidin metabolism in pea (Pisum sativum) seeds.
Proanthocyanidins (PAs) accumulate in the seeds, fruits and leaves of various plant species including the seed coats of pea (Pisum sativum), an important food crop. PAs have been implicated in human health, but molecular and biochemical characterizat

Whole shoot mineral partitioning and accumulation in pea (Pisum sativum).
Several grain legumes are staple food crops that are important sources of minerals for humans; unfortunately, our knowledge is incomplete with respect to the mechanisms of translocation of these minerals to the vegetative tissues and loading into see
