Development, and genetic and metabolic characterization of new tomato mutants with enhanced and deficient carotenoid content

Tomato (Solanum lycopersicum) is a valuable vegetable crop rich in health-protective carotenoids, but breeding improvements are limited by its narrow genetic diversity. New mutants with enhanced and deficient carotenoid content in a single genetic background of tomato cv. MicroTom were developed via...

Description
Summary:Tomato (Solanum lycopersicum) is a valuable vegetable crop rich in health-protective carotenoids, but breeding improvements are limited by its narrow genetic diversity. New mutants with enhanced and deficient carotenoid content in a single genetic background of tomato cv. MicroTom were developed via chemical mutagenesis. Genetic and metabolic analyses showed that mutant DC260, which exhibited fruit color alteration from red to deep red interlaced with orange color, had significant (P
