Genome-wide identification of invertase genes in sweetpotato and its response to nitrogen and planting densities.

ABSTRACT:

Background

Invertases (INVs) included CWIN, CIN and VIN, are key enzymes in sucrose hydrolysis into glucose and fructose and essential for plant root development. Yet the effects of nitrogen and planting density on IbINVs expression remains unexplored in sweetpotato.

Results

This study identified 22 invertase (IbINV) genes in the sweetpotato genome and conducted comprehensive analyses of their subcellular localization, gene structure, and conserved motifs and domains. Gene Ontology functional and protein interaction network analysis suggested that IbCWIN1/2/5/6 potentially interact with HKL1/3, HXK2/3/4, and other proteins, significantly influencing carbohydrate metabolic functions and biological processes in sweetpotato. Transcriptome data revealed that IbCIN2 and IbVIN3 we
