Figure 3From: Sex- and season-dependent differences in telomere length and telomerase activity in the leaves of ash and willowRepresentative TRAP analysis images used to measure the telomerase activity in leaves of male or female ash and willow. A Ash samples. Lane 1: telomerase-negative control M: 50-bp ladder DNA marker; lanes 2–4: male trees; lanes 5–7: female trees. B Willow samples. Lane 1: telomerase-negative control; lane M: 50-bp ladder DNA marker; lanes 2–5: male trees; lanes 6–9: female trees. Leaves of ash and willow were sampled in April, 2011.Back to article page
