Fresh leaves were collected, and leaf chloroplasts were extracted.. Zea mays subsp. mays

Sweet maize, originating in Central and South America, is an endosperm mutant in common maize. Sweet maize has the genetic characteristics of inhibiting the conversion of sugar to starch, with less starch accumulation and high sugar content during the kernels ripening period. So sweet maize has rich nutrition and good taste, known as "fruit maize". Considering that chloroplast genomes provide ideal information for species identification and evolution, the chloroplast of sweet maize is sequenced and compared to obtain comprehensive information on its classification and evolution.
