Arabidopsis	At4g22880	Involved in anthocyanin and protoanthocyanidin biosynthesis by catalyzing the oxidation of leucoanthocyanidins into anthocyanidins.	The Arabidopsis TDS4 gene encodes leucoanthocyanidin dioxygenase (LDOX) and is essential for proanthocyanidin synthesis and vacuole development.; 2003; DOI: 10.1046/j.1365-313x.2003.01834.x; PMID: 12940955; https://pubmed.ncbi.nlm.nih.gov/12940955/ | Arabidopsis thaliana expresses a second functional flavonol synthase.; 2009; DOI: 10.1016/j.febslet.2009.05.006; PMID: 19433090; https://pubmed.ncbi.nlm.nih.gov/19433090/ | Leucoanthocyanidin Dioxygenase in Arabidopsis thaliana: characterization of mutant alleles and regulation by MYB-BHLH-TTG1 transcription factor complexes.; 2011; DOI: 10.1016/j.gene.2011.05.031; PMID: 21683773; https://pubmed.ncbi.nlm.nih.gov/21683773/
