GDP-D-mannose pyrophosphorylase (GMP, EC 2.7.7.22) catalyzes the synthesis of GDP-D-mannose and represents the first committed step in plant ascorbic acid biosynthesis. Using potato GMP cDNA sequence as a querying probe, 65 highly homologous tomato ESTs were obtained from dbEST of GenBank and the

GDP-mannose pyrophosphorylase (GMPase, EC 2.7.7.22) catalyses the synthesis of GDP-D-mannose and represents the first committed step in the formation of all guanosin-containing sugar nucleotides found in plants which are precursors for cell wall biosynthesis and, probably more important, the

Industrially important extracellular enzymes from filamentous fungi are often O-mannosylated. The structure and function of the pmtA (AapmtA) gene encoding the protein O-D-mannosyltransferase of Aspergillus awamori were characterized. The AapmtA disruptant, designated AaPMTA, was constructed by

The present work report the unusual uranium uptake by foodstuff, especially those rich in carbohydrates like rice when they are cooked in water, contaminated with uranium. The major staple diet in South Asia, rice, was chosen to study its interaction with UO2(2+), the active uranium species in

Horn lian (Typhonium giganteum) is a perennial herb of the family Aracea and is commonly used for expelling phlegm and as an antispasmodic treatment. In August 2012, horn lian grown in Changchun, Jilin Province of China, exhibited soft rot disease with ~60% incidence and experienced great losses.

In 2001, a new disease of common bean (Phaseolus vulgaris L.) caused by Erwinia rhapontici (Millard) Burkh. was detected in seed samples from southern Alberta, Canada. Infected seeds had pink or pinkish-brown lesions on the seed coat. The disease was found in great northern (cv. US1140), pink (cv.

Konnyaku (Amorphophallus rivieri Durieu) is grown in some rural areas of China as an important cash crop. In 2011, there was a serious outbreak of Konnyaku soft rot in Xuanwei District of Yunnan Province of China. The disease was characterized by partial or complete tuber rot. At its anaphase, the

Milk thistle (Silybum marianum) is an annual or biannual plant of the Asteraceae family that produces the hepaprotectant silymarin. In 2012, almost all milk thistle grown in the medicinal herbal garden of Jilin Agricultural University (Changchun, Jilin Province, China) exhibited symptoms of a

Peace lily (Spathiphyllum wallisii Regel) is a popular ornamental potted plant in Argentina. During May of 2008 (austral autumn), necrotic lesions of unknown etiology were observed on S. wallisii in a nursery in Pontevedra (34°45'6″S, 58°42'42″W). Plants first showed water-soaked areas starting from

A cell-wall preparation from the cells of Elsinoe leucospila, which produces elsinan extracellularly when grown on sucrose or glucose-potato extract medium, was fractionated systematically. The heteropolysaccharide that was released by treatment with Actinase E digestion, comprised D-mannose,

BACKGROUND Various cytomorphologic and biochemical markers of apoptosis are found in different compartments (plasma membrane, cytoplasm, nucleus, and mitochondria) of target cells. Although the plasma membrane is an easily accessible cellular compartment, relatively little is known about its changes

Conidia of the insect-pathogenic fungus Metarhizium anisopliae var. anisopliae produced on different growth substrates (culture media or insect cadavers) demonstrate reproducibly altered tolerance to UV-B radiation [Rangel, D.E.N., Braga, G.U.L., Flint, S.D., Anderson, A.J., Roberts, D.W., 2004.

Ascorbic acid (vitamin C) is the most abundant antioxidant in plants. Its biosynthetic pathway via GDP-D-mannose and L-galactose, which was proposed only recently, is now supported by molecular genetic evidence from Arabidopsis thaliana and transgenic potato plants. Except for the last step (which
