A continuous application of ethylene (10 mul/l) and propylene (500 mul/l) to potato tubers (Solanum tuberosum L.) resulted in an upsurge of respiration and a concomitant rise in peroxides. When applied in 100% O(2), the effect of ethylene and propylene on respiration and peroxide formation was augmented. Hydrogen cyanide (500 mul/l) mimicked the action of ethylene and propylene inducing a respi...

phosphorylatson, if any, only occurs in later stages of infection. Isolation of mitochondria (Mw) from potato tuber tissue (Solanum tuberosum L.) which are reasonably intact and show respiratory control by adenosine diphosphate (ADP) has been des cribed recently.3,4) The present paper deals with some properties of Mw prepared from healthy, infected and cut potato tuber tissues. The method of ex...

HPLC used in combination with ion trap to identify target analytes tuber part potato. results s...

Pectobacterium carotovorum subsp. brasiliense is a member of the soft rot Enterobacteriaceae (SRE) family that causes tuber soft rot and blackleg diseases of stems in potato plants. Currently, there are no effective chemical strategies for the control of members of the SRE. Thus, an understanding of the inducible defense responses in stems of potato plants is important, particularly during colo...

Malnutrition is one of the world's largest health concerns. Folate (also known as vitamin B₉) is essential in the human diet, and without adequate folate intake, several serious health concerns, such as congenital birth defects and an increased risk of stroke and heart disease, can occur. Most people's folate intake remains sub-optimal, even in countries that have a folic acid food fortificatio...

The Gly decarboxylase multienzyme complex (Gly cleavage system, EC 2.1.2.10) catalyzes the conversion of Gly into COz, NH3, and 5,10-methylene-tetrahydrofolate, reducing NAD+ to NADH. The enzyme has been isolated from animals, plants, and bacteria-in animals and plants it occurs exclusively in the mitochondrial matrix, and in photosynthetic tissue it can be found in very large amounts (Bourguig...
