Plastid uridine salvage activity is required for photoassimilate allocation and partitioning in Arabidopsis.

The Plant cell - 1 Aug 2011

Chen Mingjie, Thelen Jay J

Abstract excerpt

Nucleotides are synthesized from de novo and salvage pathways. To characterize the uridine salvage pathway, two genes, UKL1 and UKL2, that tentatively encode uridine kinase (UK) and uracil phosphoribosyltransferase (UPRT) bifunctional enzymes were studied in Arabidopsis thaliana. T-DNA insertions in UKL1 and UKL2 reduced transcript expression and increased plant tolerance to toxic analogs 5-fluorouridine and...
