Trehalose metabolism in plants.
It has long been thought that the biosynthesis of trehalose, a sugar present in all kingdoms, is absent from the vast majority of higher plants. However, recent experiments have indicated that genes from Arabidopsis are able to complement yeast strains deficient in trehalose metabolism. In yeast, trehalose has been suggested as a regulatory component in the control of glycolytic flux and in a v...
متن کاملMolybdenum Metabolism in Plants
Abstrad: Among the micronutrients essential for plant growth and for microsymbionts, Mo is required in minute amounts. However, since Mo is often sequestered by Feor Al-oxihydroxides, especially in acidic soils, the concentration of the watersoluble molybdate anion available for uptake by plants may be limiting for the plant, even when the total Mo content of the soil is sufficient. In contrast...
متن کاملLipid metabolism in plants
Plants produce the majority of the world's lipids, and most animals, including humans, depend on these lipids as a major source of calories and essential fatty acids. Like other eukaryotes, plants require lipids for membrane biogenesis, as signal molecules, and as a form of stored carbon and energy. In addition, soft tissues and bark each have distinctive protective lipids that help prevent des...
متن کاملSelenium Metabolism in Plants
Selenium (Se) is an essential nutrient for many organisms, but also toxic at higher levels. While certain algae require Se to make selenoproteins, no such requirement has been shown for higher plants. Still, plants readily take up and assimilate Se using sulfur (S) transporters and biochemical pathways, and can also volatilize methylated Se. Some plants can even hyperaccumulate Se to levels aro...
متن کاملMetabolism of brassinosteroids in plants.
Brassinosteroids represent a class of plant hormones. More than 70 compounds have been isolated from plants. Currently 42 brassinosteroid metabolites and their conjugates are known. This review describes the miscellaneous metabolic pathways of brassinosteroids in plants. There are some types of metabolic processes involving brassinosteroids in plants: dehydrogenation, demethylation, epimerizati...
