Discovery of rare DNA marker in plants challenges previous assumptions
Could it be that one of only three known markers directly targeting the DNA does not exist outside the realm of microbes? Now, researchers led by Xiaoqi Feng at the Institute of Science and Technology Austria (ISTA) have demonstrated that this marker—N4-methylcytosine (4mC)—is essential for sperm development and maturation in the liverwort Marchantia polymorpha, a key organism in plant evolution.
