摘要： Currently, the PR1 gene in strawberry has not been reported yet. Therefore, in this study, the FaPR1 gene sequence was obtained and cloned based on the transcriptome data of strawberry in response to anthracnose infection. The characteristics of FaPR1-related sequences were analyzed using bioinformatics methods. Moreover, the potential interacting proteins of FaPR1 were predicted using the interaction pairs included in the STRING database, and the interaction between them was verified by the yeast two-hybrid method. In addition, the phenotypic and physiological changes of strawberry materials with overexpressed FaPR1 gene after infection by Colletotrichum gloeosporioides (Penz.) Sacc. were analyzed to provide reference genes and a theoretical basis for molecular breeding for anthracnose resistance. The main results were as follows: (1) The FaPR1 gene encodes a protein containing 162 amino acid residues with an isoelectric point of 5.52; (2) The FaPR1 protein is closely related to Rosa chinensis Jacq. PR1 (RcPR1) protein and Rosa hugonis Hemsl. PR1 (RhPR1) protein; (3) There is an interaction between FaPR1 and the strawberry thaumatin-like protein 1 (FaTLP1); (4) The FaPR1 gene plays an important role in strawberry resistance to anthracnose, and overexpression of the FaPR1 gene can enhance strawberry resistance to this disease.
