The complete chloroplast genome sequence of corn and economic analysis on production costs profits in Zhengzhou city

Corn is one of the main food crops in China. The problem of corn production cost benefit has always been the most concerned issue of farmers. In this paper, economic analysis of corn production cost benefit is conducted, and the chloroplast genome sequence is studied. The complete chloroplast genome sequence of corn was characterized from Illumina pair-end sequencing. The chloroplast genome of corn was 140,382 bp in length, containing a large single-copy region (LSC) of 82,156 bp, a small single-copy region (SSC) of 15,952 bp, and two inverted repeat (IR) regions of 21,137 bp. The overall GC content is 36.80%, while the correponding values of the LSC, SSC, and IR regions are 34.5%, 30.5%, and 42.5%, respectively. The genome contains 118 complete genes, including 85 protein-coding genes (78 protein-coding gene species), 25 tRNA genes (19 tRNA species) and 8 rRNA genes (4 rRNA species). The Neighbour-joining phylogenetic analysis showed that corn and Zea mays cultivar B73 clustered together as sisters to other Zea species.
