We studied the effect of L-lactate on both the cleavage and the condensation reactions of Pinus pinea isocitrate lyase. This compound is a competitive of Pinus pinea isocitrate lyase towards both isocitrate and glyoxylate, whereas is a mixed type inhibitor towards succinate. Assuming that L-lactate
The polyphenolic structure common to flavonoids enables them to donate electrons and exert antioxidant activity. Since the mitochondrial electron transport chain consists of a series of redox intermediates, the effect of flavonoids in a complex mixture of polyphenols, as well as related pure
Sodium pheophorbide a (SPA) is a new alternative fungicide with low toxicity and high efficiency, which has high fungicidal activity against Pestalotiopsis neglecta, a pathogen that causes black spot needle blight of Pinus sylvestris var. mongolica. To utilize SPA for plant disease control,
The effects of excision, light and cytokinin (N6-benzyladenine) on 14C-acetate metabolism in cotyledons of Pinus radiata (D. Don) were determined. 14CO2 was released and the distribution of radioactivity into lipids, sugars, organic acids and amino acids was determined. While light and cytokinin
Capillary electrophoresis methods are described for the analysis of the major inorganic anions (nitrite, nitrate, chloride, sulphate, phosphate), organic acids (oxalate, malate, citrate, succinate) and inorganic cations (ammonium, potassium, sodium, calcium, magnesium) in leaf extracts. Analytical
