Abstract: The phytohormone auxin exerts a pleiotropic effect on various aspects of plant growth and development, including cell elongation, cell division, differentiation, root initiation, apical dominance, and tropic responses. Auxin mediates these effects at the molecular level by altering the expression of numerous genes. Most early auxin response genes are classified into three families: AUX/ IAAs, GRETCHEN HAGEN3s (GH3s), and Small Auxin-Up RNA (SAUR). AUX/IAA (PF02309) family genes achieve transcript due to the induction of plant hormone auxin and part of them have an N-terminal DNA binding domain. It is a transcriptional repressor that has proved to play a very vital role in auxin signaling pathway. GH3 (PF03321) was first found in soybean later, some GH3 genes were reported and divided into three groups: one combine JA-amino acid conjugates, the others were used to produce IAA conjugates and catalyze the 30 conjugation of amino acids and 4-substituted benzoic acid. GH3 plays an important role in auxin signaling pathways, optical signaling pathways and plant defense responses; Previous reports indicated that SAUR protein contains a central domain (PF02519), and it is highly conserved. The SAUR domain mainly contains hydrophobic amino acids, short, highly conserved, charged patches and a nearly invariant cysteine residue. Around the SAUR domain, SAUR 35 proteins have lowly conservative length N- and C-terminal extensions. Small auxin-up RNAs (SAURs) are the early auxin-responsive genes represented by a large multigene family in plants. In order to recognize the SAUR (Small auxin-up RNA) gene from the whole genome of the grape, the gene of SAUR gene was identified from the whole genome of the grape, and the gene structure, amino acid characterization, chromosome localization, gene evolution,functional analysis and tissue expression analysis of the SAUR gene family were carried out. A total of 64 members of the SAUR gene family were identified and showed cluster distribution on 8 chromosomes among 19 chromosomes. The genes were mainly distributed in Chr3 and Chr4. Chr3, exist the highest number of genes, 37 were distributed in it. the length of Grape SAUR family genes is shorter, where 59 genes are intronless. Analysis of protein physical and chemical characteristics showed that most SAUR protein was alkaline, the structure stability was poor, the protein fat soluble index was high, and it was hydrophilic. The function prediction of genes showed that the SAUR gene mainly functioned as growth factors, structural proteins, transcription, transcriptional regulation and responded to stress and immunization response and immune response. Most of them were involved in growth regulation. According to the phylogenetic analysis, it was divided into 10 branches. Analysis of different tissue expression profiles showed that SAUR gene family members had different tissue expression patterns and had some regulation effect on abiotic stress. This information has laid a foundation for the functional analysis of SAUR gene family. This work will pave a a new era of applying genetic information to a deeper understanding of strawberries and used to enhance the agricultural production. Making genetic information and genomics applied in many aspects of grape production, which means that the era of application of genetic information in crop production has arrived.
