title: [Cloning and bioinformatics analysis of chalcone synthase (AsCHS1) gene in Aquilaria sinensis].
abstract: OBJECTIVE
  The study aimed to clone the open reading frame of chalcone synthase (CHS) from Aquilaria sinensis and analyze the bioinformatics and expression of the gene.
  
  
  METHODS
  One unique sequence containing CHS domain was discovered in our previous reported wound transcriptome dataset of A. sinensis. The open reading frame of CHS was cloned by RT-PCR strategy with the template of mixed RNA extracted from A. sinensis stem which treated by different wound time. The bioinformatic analysis of this gene and its corresponding protein was performed. The AsCHS1 expression in calli was analyzed with histone gene as an internal control gene under wound condition by qRT-PCR technique.
  
  
  RESULTS
  One unique sequence of CHS, named as AsCHS1, was cloned from A. sinensis. The full length of AsCHS1 cDNA was containing a 1 192 bp ORF that encoded 397 amino acids. The result of qRT-PCR displayed that the highest expression level was at 12 h, which indicated that it was possibly involved in early-stage response to wound.
  
  
  CONCLUSIONS
  Cloning and analyzing AsCHS1 gene from A. sinensis provided basic information for study the function and expression regulation of AsCHS1 in the flavonoids biosynthesis.
