Genome-wide identification and annotation of the Nuclear-factor YA gene family in cassava (Manihot esculenta Crantz)

Nuclear factor Y (NF-Y) is a transcription factor which plays an important role in the regulation of various developmental processes and stress responses in plants. By using various bioinformatics tools, the identification and analyses of the NF-YA subunit of cassava (Manihot esculenta Crantz) have been attempted in this study. A total of 12 members of the NF-YA gene family were identified in the cassava genome. They were located on the 18 cassava chromosomes with different frequencies. Several initial structural analyses of the NF-YA family were also performed. Among them, the typical gene organization of the MeNF-YA gene family contained 5 exons/4 introns. Interestingly, the conserved region of NF-YA was characterized by the interaction of NF-YB/C domain and the DNA binding domain. This study provided information on NF-Y in plants.
