Changes in sucrose synthetase activities in aging potato tuber slices.
The me-chanism by which the reversible conversion of starch ito sucrose takes place in potato tubers exposed t,o cold is as yet essentilally unknown. Early 'studies on the subjectt tried to correllate this conversion with va,riations in the activity of related enzymes (10). Those responsible for the synthesis of sucrose and sticrose-6--phosphiate (1) are undoubtedly highly relevant. In add'itio...
متن کاملDetection of sweet potato virus C, sweet potato virus 2 and sweet potato feathery mottle virus in Portugal.
Field sweet potato plants showing virus-like symptoms, as stunting, leaf distortion, mosaic and chlorosis, were collected in southwest Portugal and tested for the presence of four potyviruses, sweet potato virus C (SPVC), sweet potato virus 2 (SPV2), sweet potato feathery mottle virus (SPFMV), sweet potato virus G (SPVG), and the crinivirus sweet potato chlorotic stunt virus (SPCSV). DsRNA frac...
متن کاملSucrose Metabolism in Tubers of Potato (Solanum tuberosum L.): Effects of Sink Removal and Sucrose Flux on Sucrose-Degrading Enzymes.
Excision of developing potato (Solanum tuberosum L.) tubers from the mother plant, followed by storage at 10 degrees C, resulted in a rapid, substantial decrease in sucrose synthase activity and considerable increases in hexose content and acid invertase activity. A comparison of the response of three genotypes, known to accumulate different quantities of hexoses in storage, showed that both su...
متن کاملSweet-potato Scurf
The scurf disease of the sweet potato (Ipomoea batatas) was first described by Halsted, who published a brief account of it in 1890. To the fungus he gave the name Monilochaetes infuscans, a new genus and species, of which, unfortunately, he gave no technical description. For many years following his pioneer work little or no attention was given to sweet-potato diseases. This very common and in...
متن کاملLocalization of sweet potato chlorotic stunt virus (SPCSV) in synergic infection with potyviruses in sweet potato.
Among diseases reported worldwidely for sweet potato (Ipomoea batatas (L) Lam) crop, one of the most frequent is the Sweet potato virus disease (SPVD), caused by sweet potato chlorotic stunt virus (SPCSV) and sweet potato feathery mottle virus (SPFMV) co-infection. In Argentina, there exists the sweet potato chlorotic dwarf (SPCD), a sweet potato disease caused by triple co-infection with SPCSV...
