Many insect pest species also transmit viruses. The sapsucking species are effective virus vectors, delivering virus particles directly into the vascular tissue, thereby permitting their rapid dissemination throughout the plant

Mutations in dnaA render replication asynchronous, which suggests that DnaA could be the “titrator” or “clock” that measures the number of origins relative to cell mass.

Cytokinin has been linked to the activation of a Cdc25- like phosphatase, whose role is to remove an inhibitory phosphate group from the Cdc2 kinase. 

Cytokinins elevate the expression of the CYCD3 gene, which encodes a D-type cyclin'

In addition to proteins involved in NER, a variant form of XP called XP-V is caused by a defect in the translesion DNA polymerase, Pol h. The gene encoding Pol h is sometimes called XPV. Individuals with XP-V have a milder form of XP.
