What is Manipulation of fruit sugar composition but not content in Lycopersicon esculentum fruit by introgression of an acid invertase gene from Lycopersicon pimpinellifolium about?

## Summary The effects are shown here of genetic manipulation of invertase on fruit sugar metabolism in tomato. Introgression of the acid invertase gene on chromosome 3 from __Lycopersicon pimpinellifolium__ (an accession containing high invertase activity) into __Lycopersicon esculentum__ (with relatively low activity) was used to study effects on fruit development and both sugar composition and content. The __L. pimpinellifolium__ parent fruit had higher fruit invertase activities, greater hexose contents and lower sucrose accumulation that the __L. esculentum__ parent. A strong correlation between fruit invertase activity and soluble sugar content was observed only in the __L. pimpinellifolium__ parent and not in the homozygous fruit from either cross. In all cases high soluble acid invertase activities prevented sucrose accumulation and led to the build‐up of hexoses. The introgression of the invertase locus from __L. pimpinellifolium__ into __L. esculentum__ did not result in higher soluble solids in the progeny than in the __L. esculentum__ parent, but it did modify their relative composition. Changes in the invertase gene composition alone are not sufficient to increase frui
