Humans have the enzyme hSMUG1, which removes any U residues that occur in single-stranded DNA during replication or transcription.  Two other human DNA glycosylases, TDG and MBD4, remove either U or T residues paired with G, generated by deamination of cytosine or 5-methylcytosine, respectively.

When plants recognize elicitors from insect saliva, An increase in the cytosolic Ca2+ concentration ([Ca2+]cyt) is an early signal that mediates insect elicitor–induced responses.
