Tuber transcriptome analysis reveals a novel WRKY transcription factor StWRKY70 potentially involved in potato pigmentation.

Tuber flesh pigmentation, conferred by the presence of secondary metabolite anthocyanins, is one of many key agronomic traits for potato tubers. Although several genes of potato anthocyanin biosynthesis have been reported, transcription factors (TFs) contributing to tuber flesh pigmentation are still not fully understood. In this study, transcriptomic profiling of diploid potato accessions with or without tuber flesh pigmentation was conducted and genes of the anthocyanin biosynthesis pathway were found significantly enriched within the 1435 differentially expressed genes (DEGs).

Genome-wide identification of microRNAs involved in the regulation of fruit ripening and climacteric stages in melon ().

Fruit ripening is influenced by multiple plant hormones and the regulation of genes. However, studies on posttranscriptional regulators (e.g.
