Characteristics of <i>LDOX</i> Gene Structure Analysis and Construction of Protein Interaction Network in <i>Actinidia arguta</i>

The purpose of this study is to reveal the structure and function leucoanthocyanidin dioxygenase ( LDOX ) gene in Actinidia arguta . Bioinformatics methods were used analyze nucleotide amino acid sequences , construct protein interaction network gene, conduct GO KEGG functional annotation analysis. results showed that there 10 conserved motifs which was closely related Vaccinium corymbosum Lonicera japonica  and Daucus carota Cis-regulated elements mainly involved ABA signaling pathways, responding drought response, anaerobic induction, gibberellic acid, auxin response factor, MeJA low temperature photostimulus response. Physical chemical properties structural analysis it hydrophilic protein, no signal peptide transmembrane regions found, including Ser phosphorylation sites (13), Thr (12) Tyr (6). There two O-glycosylation (Thr 4 323 Asn 107 N- glycosylation at residues ranging from 109. a domain conservative 48-347 bp 20G-FeⅡ Oxy. secondary main random coil (43.10%). certain between proteins such as F3H, UFGT, FLS PAL, flavonoid biosynthesis metabolism process plays an important role plant-type vacuole membrane, regulates catalytic activity redox active molecule.  gene highly regulatory progesterone pathway, provides theoretical basis for further research on mechanism
