Tomato hydroxymethylglutaryl-CoA reductase is required early in fruit development but not during ripening.

The activity of 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) and the level of its mRNA have been determined at various stages of tomato fruit development. The HMGR reaction makes mevalonate, a necessary component in the synthesis of all isoprene containing compounds, such as sterols and carotenoids. A cDNA clone encoding the active site region of HMGR has been isolated from a tomato l...

Fruit cuticle lipid composition during development in tomato ripening mutants.

Recent studies suggest that fruit cuticle is an important contributing factor to tomato (Solanum lycopersicum) fruit shelf life and storability. Moreover, it has been hypothesized that variation in fruit cuticle composition may underlie differences in traits such as fruit resistance to desiccation and microbial infection. To gain a better understanding of cuticle lipid composition diversity dur...

Regulation of carotenoid formation during tomato fruit ripening and development.

Carotenoid biosynthesis and its regulation during tomato fruit development and ripening is a complex process that occurs alongside the differentiation of chloroplasts into chromoplasts and changes to the organoleptic properties of the fruit. Unusually for plants, the ripe tomato fruit accumulates large amounts of lycopene, as the pattern of gene expression found in green fruit changes during fr...

Regulation of tomato fruit ripening

Fruit ripening is a sophisticatedly orchestrated developmental process, unique to plants, that results in major physiological and metabolic changes, ultimately leading to fruit decay and seed dispersal. Because of their strong impact on fruit nutritional and sensory qualities, the ripeningassociated changes have been a matter of sustained investigation aiming at unravelling the molecular and ge...

Changes in Gene Expression during Tomato Fruit Ripening.

Total proteins from pericarp tissue of different chronological ages from normally ripening tomato (Lycopersicon esculentum Mill. cv Rutgers) fruits and from fruits of the isogenic ripening-impaired mutants rin, nor, and Nr were extracted and separated by sodium dodecylsulfate-polyacrylamide gel electrophoresis. Analysis of the stained bands revealed increases in 5 polypeptides (94, 44, 34, 20, ...
