Chromoplasts are carotenoid-accumulating plastids found in many fruits and flowers. In a new paper, Li and colleagues show that the Or gene of cauliflower induces differentiation of β-carotene-containing chromoplasts in the (normally non-pigmented) curd tissue. This is the first time that a gene product controlling chromoplast differentiation is described. Or encodes an evolutionarily conserved DnaJ cysteine-rich domain-containing protein that can be used for metabolic engineering in crop plants, such as potato. © 2007 Elsevier Ltd.
