Aharoni et al. (2001) found that ectopic expression of FaMYB1, a strawberry fruit ripening transcription factor containing the repressor domain, resulted in the reduced Cya content and other flavonoid content, which in turn confirmed that Cya is the major anthocyanin determines the petal colour in tobacco plants.
Orthologs of RIN and SPL (squamosa) tomato transcription factors, which are known to be very important fruit ripening trancription factors [ 63, 64], were at much higher transcript levels in the skin and decline with °Brix level (Additional file 2).
The tomato SlPSY1 and SlPSY2 are targets of the MADS-box transcription factor Ripening Inhibitor, and SlPSY1 gene expression and enzyme activity is inhibited by tomato Stay-green 1 [ 82, 83].
In addition to the sequence information and full-length clones developed in this work, digital analyses of EST abundance in the four different post-harvest conditions has revealed a large number of candidate genes with fluctuating transcript levels in response to factors such as ripening, long-term cold storage and a combination of these two factors (ripening + long-term cold storage).
All remaining peaks were then tested for detection performance of biological variance by fitting a linear model between the estimated abundance and first order predictors based on the experimental factors ripening stage, genotype, treatment and harvesting time.
In the cases where regulation of SlTCP expression by ripening regulatory transcription factors was detected, but no binding to the target promoter was observed, several other scenarios are possible.
These ripening-associated transcription factors regulate ripening through the biosynthesis of ethylene and/or its signalling.
The ACO gene has been previously studied in apple and reported to be a key factor in ripening processes in peach, such as ethylene biosynthesis, pigmentation, cell wall metabolism, carbohydrate metabolism and signal transduction.
We previously indicated the presence of up-regulated transcription factors in ripening tomato fruit by data mining in TIGR Tomato Gene Index.
To identify the molecular mechanisms associated with developing wooliness, we have taken a global approach towards identifying genes that are differentially expressed in response to factors such as cold, ripening, or the combined effects of these two factors (cold + ripening), the latter of which results in the woolly peach phenotype.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
