Genomic Analysis Points to Multiple Genetic Mechanisms for Non-Transformable ST-50.

and are well known for their natural competence, i.e., their capacity for the uptake of naked DNA with subsequent transformation.

Coordinated transcriptional regulation of the carotenoid biosynthesis contributes to fruit lycopene content in high-lycopene tomato genotypes.

Lycopene content in tomato fruit is largely under genetic control and varies greatly among genotypes. Continued improvement of lycopene content in elite varieties with conventional breeding has become challenging, in part because little is known about the underlying molecular mechanisms in high-lycopene tomatoes (HLYs). We collected 42 HLYs with different genetic backgrounds worldwide.
