甜菜NAC转录因子家族的全基因组鉴定OA

Objective To identify and conduct a bioinformatics analysis of the NAC transcription factor family in sugar beet,providing a theoretical basis for further investigation of the NAC gene family in this species.Method Bioinformatics methods were employed to conduct a genome-wide identification of the NAC transcription factor gene family members in sugar beet.Various software tools,including ExPASy,Cell-PLoc 2.0,MEME,TBtools,and MEGA,were utilized for predictive analysis of their physicochemical properties,subcellular localization,chromosomal locations,phylogenetic relationships,gene structures,conserved domains,cis-acting elements,and gene synteny.Result The results indicated that a total of 27 NAC transcription factor gene family members were identified in the sugar beet genome,distributed unevenly across the chromosomes.All members possessed the conserved NAM domain,with 23 of these genes predicted to be localized in the nucleus.Based on their phylogenetic relationship with Arabidopsis thaliana,the sugar beet NAC genes were classified into 16 subfamilies alongside Arabidopsis.Analysis of gene structures revealed that most genes contain both exons and introns.Cis-acting element analysis suggested that these NAC transcription factors may be involved in responses to various biotic and abiotic stresses.Conclusion The NAC genes in sugar beet are relatively evolutionarily conserved but exhibit functional diversity.They are involved in the growth and development of sugar beet and play important roles in its stress resistance.
