Analysis of the Alternative Splicing Events of Exogenous δ-Aminolevulinic Acid under NaCl Stress in Wild Jujube Seedlings

Salt injury, as an abiotic stress factor, seriously affects the quality and yield of crops. This study was conducted by analyzing alternative splicing in control (CK), δ-aminolevulinic acid (ALA), NaCl, ALA + NaCl treatments wild jujube (Zizyphus spinosus (Bunge)Hu) using RNA-seq. It found that unique differential is closely related to alleviation salt analyzed intermediates chlorophyll synthesis content leaves. The results showed were reduced disrupted leaves under stress, exogenous spraying could alleviate effect on chlorophyll. RNA-seq indicated genes dominated exon skipping all experimental treatments. Gene Ontology Kyoto Encyclopedia Genes Genomes analyses revealed CK comparison groups primarily enriched porphyrin metabolism, chloroplast, energy metabolism pathways. hypothesized treatment can effects altering photosynthesis, jujube. In addition, verification with significantly upregulated expression HEMH, UROIII, ChlD increased biosynthetic endogenous ALA, porphobilinogen, protoporphyrin IX, Mg-protoporphyrin protochlorophyllide, which served
