Update on Plant Lipoxygenases Plant Lipoxygenases. Physiological and Molecular Features
Lipoxygenases (LOXs; EC 1.13.11.12) are nonheme iron-containing dioxygenases widely distributed in plants and animals. LOX catalyzes the addition of molecular oxygen to polyunsaturated fatty acids containing a (Z,Z)-1,4-pentadiene system to produce an unsaturated fatty acid hydroperoxide. LOX initiates the synthesis of a group of acyclic or cyclic compounds collectively called oxylipins, which ...
متن کاملSoybean leaves contain multiple lipoxygenases.
Chromatofocusing of soybean (Glycine max L.) leaf lipoxygenases revealed three distinct peaks of activity. Based on their isoelectric points (pls), pH optima, and mutant analysis it appears that the leaf isozymes are different from those described from mature soybean seed. At least one leaf lipoxygenase appears to differ from those found in hypocotyls. The pls of the main bands of the three lea...
متن کاملEffects of seed aging on subsequent seed reserve utilization and seedling growth in soybean
Reduced seedling growth is a consequence of seed deterioration. The heterotrophic seedling growth can be considered as the product of three components: (1) initial seed weight, (2) the fraction of seed reserves which are mobilized, and (3) the conversion efficiency of mobilized seed reserves to seedling tissues. It is not clear which of these component (s) is affected by seed deterioration. To ...
متن کاملEffects of exogenous auxins on expression of lipoxygenases in cultured soybean embryos.
The expression of lipoxygenases (LOXs) is known to be developmentally regulated in soybeans (Glycine max. [L.] Merr.). Hormones have been firmly established as being involved in the growth and developmental processes of a number of plant species. Correlation between the expression of LOXs and the development and germination of soybean embryos suggests that plant hormones may affect the expressi...
متن کاملNitrogen Fertilizer Effects on Soybean Growth, Yield, and Seed Composition
While previous research has been contradictory, potential grain yield responses and seed protein increases have led to con tinuing interest in N fertilizer application to soybean (Glycine max (L.) Merr.]. Field experiments were conducted at seven lo cations from 1990 to 1991 in Alabama to determine soybean response to N fertilization at various growth stages. Treatments included a factorial a...
