Pyrophosphate levels strongly influence ascorbate and starch content in tomato fruit
Ascorbate (vitamin C) deficiency leads to low immunity, scurvy, and other human diseases and is therefore a global health problem. Given that plants are major ascorbate sources for humans, biofortification of this vitamin in our foodstuffs is of considerable importance. Ascorbate is synthetized by a number of alternative pathways: (i) from the glycolytic intermediates D-glucose-6P (the key inte...
متن کاملRegulation of tomato fruit ascorbate content is more highly dependent on fruit irradiance than leaf irradiance.
BACKGROUND AND AIMS The mechanisms involving light control of vitamin C content in fruits are not yet fully understood. The present study aimed to evaluate the impact of fruit and leaf shading on ascorbate (AsA) accumulation in tomato fruit and to determine how fruit sugar content (as an AsA precursor) affected AsA content. METHODS Cherry tomato plants were grown in a glasshouse. The control ...
متن کاملSucrose Synthase, Starch Accumulation, and Tomato Fruit Sink Strength.
Contrasting evidence has accumulated regarding the role of acid invertase and sucrose synthase in tomato fruit sink establishment and maintenance. In this work the relationships among the activities of sucrose synthase and acid invertase, Lycopersicon esculentum Mill cv UC-82B fruit growth, and starch accumulation were analyzed in fruit at 0 to 39 d after anthesis. Sucrose synthase, but not aci...
متن کاملInfluence of KSB, PSB and NFB on fruit quality and potassium contents in tomato
To evaluate the inoculation effect of potassium releasing, phosphate solubilizing and nitrogen fixing bacteria on the fruit quality of tomato, an experiment based on randomized complete block design with 9 treatments and 3 replications has been conducted. In this experiment, tomato (super chief cv.) seedlings of the in the treasury cultivation with single and combined treatments of the potassiu...
