Abstract:

The objective of this study was to identify the PAT gene family in three kinds of Apiaceae vegetable crops (Daucus carota, Apium graveolens, Coriandrum sativum) at genome scale and provide a reference for further exploration of their roles in plant growth, development and stress tolerance. The PAT proteins were identified from genomes of the three species by BLAST and hmmsearch. TBtools was used to depict chromosome locations of PAT genes. The isoelectric point and molecular weight were analyzed by Expasy. TMHMM-2.0, CELLO v.2.5 and WoLF PSORT were used to predict transmembrane regions and subcellular localization of PAT. MEGA6 was used to construct the phylogenetic tree, and MEME was used to analyze conserved motifs of PAT proteins. Based on real time quantitative PCR results and transcriptome data, TBtools was used to draw gene expression heat map, and tissue expression characteristics and responses to stress of PAT genes were analyzed. The results showed that 27, 25, 27 PAT gene family members were identified in Daucus carota, Apium graveolens, Coriandrum sativum respectively, which were named as DcPAT1-27, AgPAT1-25, CsPAT1-27. These members with transmembrane regions distributed unevenly on chromosomes of three species, and they had different physical and chemical properties. According to phylogenetic analysis, PAT proteins from Apiaceae and other species were divided into 7 groups, and Apiaceae PAT proteins were distributed throughout all groups. Structural analysis showed that all PAT proteins had DHHC-CRD domain, and conserved amino acid residues in this domain had varied among different species. Gene expression analysis showed that the expression levels of PAT genes were different across different tissues of Daucus carota, Apium graveolens, Coriandrum sativum. Some members showed high or low expression levels in all tissues, and the expression levels of some DcPAT genes had changed after salt stress or low temperature stress.
