Weighted Gene Co-Expression Network Analysis Reveals Key Pathways and Hub Genes Associated with Successful Grafting in Pecan (Carya illinoinensis)

Patch budding (bud grafting) is a commonly used method for pecan reproduction; however, the grafting survival rate varies with cultivars. Clarifying underlying mechanisms of successful pivotal graft technique improvement. Here, weighted gene co-expression network analysis (WGCNA) was conducted to dissect key pathways and genes related pecan. Based on transcriptome data two contrasting cultivars (an easy-to-survive cultivar ‘Pawnee’ difficult-to-survive ‘Jinhua’) in response budding, all variable transcripts were grouped into 18 modules. There modules that significantly correlated trait different Enrichment showed several enriched ontology (GO) terms oxidative detoxification associated hormone signaling pathway occupied high ratio A total 52 hub identified, 48 promoter polymorphisms between Our study suggested probably The identified here might be led divergence rates among results will lay foundation future improvement
