Holliday junction resolvases mediate chloroplast nucleoid segregation

Resolution achieved Chloroplasts possess multiple copies of their own chloroplast DNA that are packaged into DNA-protein complexes known as nucleoids. The shape, number, and distribution of chloroplast nucleoids change markedly depending on the cell cycle, developmental stage, and nutritional environment. Kobayashi et al. identified Holliday junction resolvase as a key factor in the dynamism of chloroplast nucleoids in the unicellular green...
