Bioinformatics analysis of bZIP gene family of Panax ginseng

Objective To analyze bZIP gene family bioinformatics of Renshen (Panax ginseng), so as to provide theoretical basis for the development and utilization of ginseng functional genes. Methods Using PlantTFDB database to predict ginseng bZIP gene; The genetic family information and characteristics of ginseng bZIP were obtained through ExPASy website; The conserved gene sequences of PgbZIP gene family were analyzed by MEME website; The phylogenetic relationship of PgbZIP gene family were established by using MEGA software; PgbZIP expression analysis were conducted by TBtools software. Results The ginseng genome contained 157 bZIP gene family members, of which 152 were located in the nucleus, and the remaining five were located in the chloroplast and endoplasmic reticulum, respectively. The relative molecular mass was between 14 009.93 and 83 440.38, and the isoelectric point was in the range of 4.53—10.05, the number of amino acids was between 120 aa—760 aa, except for PgbZIP157, all were hydrophilic proteins. The expression level of PgbZIP131 under drought stress was 83.47; the expression level of PgbZIP99 was the highest under root (119.82) and salt stress (117.86) conditions, respectively; the expression level of PgbZIP117 in leaves was 48.54; the highest expression level of PgbZIP106 in flowers was 79.55; The highest expression level of PgbZIP118 in mature fruits was 119.32; the highest expression level of PgbZIP101 in immature fruits was 65.32. Conclusion It is speculated that PgbZIP99 has similar functions to the homologous gene AtbZIP11, and can regulate root meristem activity; PgbZIP131 has the highest expression under drought stress conditions, and it is speculated that PgbZIP131 has an important regulatory effect on drought stress; A subfamily members ABF2/AREB1, ABF3, ABF4/AREB2 is involved in the regulation of drought stress and salt stress. It is speculated that PgbZIP74, PgbZIP132, PgbZIP122 and PgbZIP112, which have a homologous relationship with members of subfamily A, have similar regulatory effects under drought stress and salt stress.
