Transcriptome analysis of table grapes (Vitis vinifera L.) identified a gene network module associated with berry firmness.

ABSTRACT: Berry firmness is one of the main selection criteria for table grape breeding. However, the underlying genetic determinants and mechanisms involved in gene expression during berry development are still poorly understood. In this study, eighteen libraries sampled from Vitis vinifera L. cv. 'Red Globe' and 'Muscat Hamburg' at three developmental stages (preveraison, veraison and maturation) were analyzed by RNA sequencing (RNA-Seq). The firmness of 'Red Globe' was significantly higher than that of 'Muscat Hamburg' at the three developmental stages. In total, a set of 4,559 differentially expressed genes (DEGs) was identified between 'Red Globe' and 'Muscat Hamburg' in the preveraison (2,259), veraison (2030) and maturation stages (2682), including 302 transcription factors (TFs).
