Sucrose Phosphate Synthase , Sucrose Synthase , and Invertase Activities in Developing Fruit of Lycopersicon esculentum Mill . and the Sucrose Accumulating Lycopersicon hirsutum Humb . and Bonpl . 1 Daphne Miron and Arthur
The green-fruited Lycopersicon hirsutum Humb. and Bonpi. accumulated sucrose to concentrations of about 118 micromoles per gram fresh weight during the final stages of development. In comparison, Lycopersicon esculentum Mill. cultivars contained less than 15 micromoles per gram fresh weight of sucrose at the ripe stage. Glucose and fructose levels remained relatively constant throughout develop...
متن کاملREGULATION OF CELLULASE AND PECTINASE ACTIVITIES IN CHERRY TOMATO (Lycopersicon esculentum MILL var. cerasiforme) FRUIT BY USE OF 1-METHYLCYCLOPROPENE
Softening, which accompanies ripening fruits is also to a large extent, responsible for the damage that occurs during handling and shipping. The effects of 1-Methylcyclopropene (1-MCP) application at different ripening stages (mature green, breaker, breaker + 2 days and breaker + 4 days) on cellulase and pectinase activities of cherry tomato fruit (Lycopersicon esculentum Mill. var. cerasiforme...
متن کاملPurification of Endosperm Sucrose Synthase From Guichao
Sucrose synthase activity in rice is potentially yield limiting. Earlier research indicated that endosperm sucrose synthase activity during grain filling was higher in ‘Guichao’ rice than in U.S. rice cultivars. We set about to purify sucrose synthase from Guichao endosperm as part of an overall research effort to understand the physiological reasons for the high yields of Guichao compared to U...
متن کاملSucrose Synthase in Wild Tomato, Lycopersicon chmielewskii, and Tomato Fruit Sink Strength.
Here it is reported that sucrose synthase can be readily measured in growing wild tomato fruits (Lycopersicon chmielewskii) when suitable methods are adopted during fruit extraction. The enzyme also was present in fruit pericarp tissues, in seeds, and in flowers. To check for novel characteristics, the wild tomato fruit sucrose synthase was purified, by (NH(4))(2)SO(4) fraction and chromatograp...
متن کاملPurification and some properties of a lectin from the fruit juice of the tomato (Lycopersicon esculentum).
In the tomato (Lycopersicon esculentum) plant, the fruit juice was found to be the richest source of agglutinating activity. The lectin responsible could be inhibited by oligomers of N-acetylglucosamine, and this property was exploited to purify the lectin by affinity adsorption on trypsin-treated erythrocytes. The lectin is a glycoprotein that cross-reacts immunologically with the lectin from ...
