菊属植物PIN基因家族的鉴定及生物信息学分析
Identification and bioinformatics analysis of PIN gene family in chrysan-themum plants
摘要
Abstract
The PIN protein family is an auxin efflux carrier responsible for transporting auxin from intracellular to extracellular space,a process that is essential for the distribution of auxin and the establishment of concentration gradients in plants.In this study,113 members of the PIN gene family were identified in five species of chrysanthemum plants by bioinformatics methods,and their physicochemical properties were analyzed in depth,revealing the diversity of physical and chemical properties of these members.By constructing a phylogenetic tree,we found that these PIN genes were divided into six distinct branches,and the closely related members presented similar conserved motifs and conserved domains,suggesting that they may have similar or related functions.Chromosome localization and collinearity analysis further demonstrated the distribution patterns of PIN genes in chrysanthemum plants,as well as their replication and rearrangement events in the genome.In addition,promoter cis-acting element analysis showed that the promoter region of the PIN gene was rich in regulatory elements related to growth and development,hormone signal transduction and stress response,suggesting that the PIN gene may be regulated by multiple signals in plant growth and development and environmental adaptation.Gene expression analysis showed that the PIN gene presented specific expression patterns in different organs of chrysanthemum plants.The above results provide a theoretical basis for the subsequent study of the function of the PIN gene in chrysanthemum plants.关键词
