Solanum lycopersicumTranscriptome or Gene expression


ABSTRACT: Gene expression in wild-type fruit. Strand-specific RNA-Seq data was used to calculate the gene expression value (RPKM) in four wild-type fruit developmental stages including immature fruit at 17DPA, mature green fruit (seeds development completes) at 39DPA, breaker fruit (onset of ripening) at 42DPA and fully ripe fruit at 52DPA. For each sample, two to four biological replicates were sequenced. Note: Samples in SRA were assigned the same sample accession. This is incorrect as there are different samples, hence “Source Name” was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.

Ripening of tomato fruits is triggered by the plant hormone ethylene, but its effect is restricted by an unknown developmental cue to mature fruits containing viable seeds. To determine whether this cue involves epigenetic remodeling, we expose tomatoes to the methyltransferase inhibitor 5-azacytidine and find that they ripen prematurely. We performed whole-genome bisulfite sequencing on fruit in four stages of development, from immature to ripe. We identified 52,095 differentially methylated re  ...[more]
