First Report of Impatiens necrotic spot virus in Hoya carnosa in Korea

Pregnanes and pregnane glycosides from Hoya carnosa.

Eleven pregnanes were isolated from the hydrolysate of the CHCl3 extract fractionated from the caules of Hoya carnosa. Among these, six pregnanes, including 19-acetoxydigipurpurogenin II, were new, and their structures were elucidated. The structures of twenty new pregnane tetraosides and pentaosides, named hoyacarnosides A-T, besides three known ones from the CHCl3 extract, were determined.

First report on infectious necrotic enteritis in piglets in Iran

Malate metabolism in Hoya carnosa mitochondria and its role in photosynthesis during CAM phase III.

This study investigated the respiratory properties and the role of the mitochondria isolated from one phosphoenolpyruvate carboxykinase (PCK)-CAM plant, Hoya carnosa, in malate metabolism during CAM phase III. The mitochondria showed high malate dehydrogenase (mMDH) and aspartate amino transferase (mAST), and a significant amount of malic enzyme (mME) activities. H. carnosa readily oxidized mal...

Effects of Protease Inhibitors on the Proteins in Two Dimensional Electrophoresis Maps of Hoya carnosa Mitochondria

The analysis and characterizations of complex protein mixtures are the central aims of proteomics. The core technology of proteomics is 2DE which simultaneously separates and displays hundreds to thousands of proteins. In the 2DE technique, the sample preparation step with high protection against proteolysis is one of the necessary steps for high quality resolution of proteins in 2DE maps. The ...

First Report of Septoria centellae Associated with Leaf Spot of Centella asiatica in Korea

Septoria centellae associated with leaf spot of Centella asiatica is reported for the first time in Korea. The fungus is described and illustrated in detail. It is also compared with related species of Septoria present on Centella and Hydrocotyle spp. with taxonomic comments. Two monoconidial isolates from Jeju and Wando were successfully cultured and have been deposited in the Korean Agricultu...
