Table 4 DNA genotype of archaic grains and modern rice accessions by specific primer set in the nuclear genome

From: Classification of archaic rice grains excavated at the Mojiaoshan site within the Liangzhu site complex reveals an Indica and Japonica chloroplast complex

  1. aNumerical number indicates number of accessions in modern rice accessions
  2. bElectrophoresis and sequencing were used to detect an expected DNA fragment in regions qSH1, sh4 and DJ6 and the size of each DNA fragment was used as the genotype name. “F1–R1” or “F1–R2” are primer set in DJ6. NA = Not amplification by specific primer set
