WebbThe history of modern-day maize begins at the dawn of human agriculture, about 10,000 years ago. Ancient farmers in what is now Mexico took the first steps in domesticating maize when they simply chose which kernels (seeds) to plant. These farmers noticed that not all plants were the same. Total RNA was isolated from immature ears (2–3 cm in length) and other tissues using TRI reagent (Molecular Research Center). Northern blots using ∼12 µg total RNA of sample per lane were performed using standard procedures (see Supplementary Information). Complementary DNA for real-time … Visa mer A W22 × W22:tga1 F2 fine-mapping population of 3,106 plants that segregated for Tga1-maize versus tga1-teosinte1 was generated by self-pollinating F1 hybrids of the parental stocks. … Visa mer After genetic mapping demonstrated that tga1 lies within the BAC c126f15, we shotgun-sequenced it to 7 × coverage (see Supplementary Information).
