Abstract:

To reveal the sequence characteristics,subcellular localization,and expression pattern of PatASIL2,belonging to the Trihelix transcription factor family,the PatASIL2 gene was first cloned using the cDNA of Pogostemon cablin (patchouli)as a template,and the bioinformatics analysis was further performed.The PatASIL2-EGFP expressed vector was constructed and transformed into Arabidopsis protoplasm to investigate the subcellular localization of PatASIL2.The real-time quantitative reverse transcription PCR(qRT-PCR)was also performed to detect the expression profiles of PatASIL2 gene in different tissues of patchouli and under treatments of methyl jasmonate(MeJA),salt stress,drought stress,and cold stress.The results indicated that PatASIL2 gene contained an open reading frame of 1 035 bp and encoded 344 amino acids.The PatASIL2 protein was an unstable hydrophilic protein without transmembrane domains and signal peptides and had 41 serine phosphorylation sites and one Myb_DNA-bind_4 conserved domain.The phylogenetic analysis showed that PatASIL2 was classified into the SIP1 subfamily of Trihelix transcription factor family,and clustered closely with Sesamum indicum SiASIL2.The subcellular localization result indicated that PatASIL2 was a nuclear-localized protein.The qRT-PCR results indicated that PatASIL2 expressed in the young leaf,mature leaf,old leaf,stem,and root in patchouli,particularly with the highest expression in the old leaf.The PatASIL2 expression was significantly upregulated by MeJA at 12—24 h and salt stress at 3—24 h.The expression of PatASIL2 was significantly upregulated at 24 h after drought treatment,and at 12 h after cold treatment.
