Abstract
Helianthus annuus J-01 was sequenced using a high-throughput sequencing platform, and the structural characteristics of the whole chloroplast genome sequence were analyzed. The results showed that the H. annuus J-01 chloroplast genome, like most higher plants, has a typical circular double-stranded tetrad structure. The chloroplast genome size is 151142bp, GC content is 38.99%, and a total of 127 genes have been annotated, including 84 protein-coding genes, 35 tRNA genes and 8 rRNA genes. A total of 18 genes in the H. annuus J-01 chloroplast genome contain introns, of which ycf3 and clpP genes contain 2 introns. In protein-coding genes, leucine is the amino acid with the highest codon encoding rate, and the amino acid with the lowest encoding rate is cysteine. The A/T content of the third codon is 69.32%, and the third codon of the H. annuus J-01 chloroplast genome coding gene prefers to use A/T.
