Genome-wide analysis of tomato NF-Y factors and their role in fruit ripening

摘要

BackgroundFruit ripening is a complex developmental process that depends on a coordinated regulation of numerous genes, including ripening-related transcription factors (TFs), fruit-related microRNAs, DNA methylation and chromatin remodeling. It is known that various TFs, such as MADS-domain, MYB, AP2/ERF and SBP/SPL family proteins play key roles in modulating ripening. However, little attention has been given to members of the large NF-Y TF family in this regard, although genes in this family are known to have important functions in regulating plant growth, development, and abiotic or biotic stress responses.
