Findings clarify the specialized function of two TKs in A. thaliana and establish that the [nucleotide] salvage pathway mediated by the kinases is essential for plant growth and development. [AtTK1]
Title: Thymidine kinases share a conserved function for nucleotide salvage and play an essential role in Arabidopsis thaliana growth and development.

suggest that thymidine kinase 1a contributes to several DNA repair pathways by providing deoxythymidine triphosphate that serve as precursors for DNA repair and to balance deoxyribonucleotides pools
Title: Arabidopsis thaliana thymidine kinase 1a is ubiquitously expressed during development and contributes to confer tolerance to genotoxic stress.

Data show that thymidine kinase was encoded by AtTK1a (AT3G07800) and (AT5G23070), and deoxyadenosine, deoxyguanosine and deoxycytidine kinase activities were encoded by a single AtdNK (AT1G72040) gene.
