Modeling the metachronous ripening pattern of mature green tomato as affected by cultivar and storage temperature.

Nutritional benefits and organoleptic characteristics, including visual, textural, taste, and flavor, are the critical characteristics of economically important fruit. Ripening is a crucial phenomenon in the formation of these quality characteristics in fruits. Therefore, controlling the ripening phenomenon is extremely important not only to maximize the benefits of the fruit but also to avoid food losses caused by over-ripening.

Epigenetic modifications of the 35S promoter in cultured gentian cells.

Our previous studies found strict gene silencing associated with CaMV-35S promoter-specific de novo methylation in transgenic gentian plants. To dissect the de novo methylation machinery, especially in association with histone modification, 35S-driven sGFP-expressing and -silenced gentian cultured cell lines that originated from a single transformation event were produced and used for epigenetic analyses. A sGFP-expressing primarily induced cell suspension culture (PS) was hypomethylated in the 35S promoter region, although a low level of de novo methylation at the 35S enhancer region (-148 to -85) was detected.
