Examples of DNA degradation in V. faba tissues. Lanes 1–15: DNA extracted individually from 15 embryos dissected from 24-hour imbibed seeds. DNA in lanes 1–5, 6–10, and 11–15 were extracted using the battery-operated, laboratory, and manually-operated microcentrifuges, respectively. Lanes 16–30: DNA extracted individually from 15 embryos dissected from seeds that had been left at 21°C for 48 hours, following 24 hours of imbibition. DNA in lanes 16–20, 21–25, and 26–30 were extracted using the battery-operated, laboratory, and manually-operated microcentrifuges, respectively.
