title: One-Step Generation of Chromosomal Rearrangements in Rice.
abstract: The combination of the DNA sequence-specific recombination system Cre/LoxP and the DNA transposon system Activator (Ac)/Dissociation (Ds) has been used for insertional and deletional mutagenesis, as well as for the generation of artificial ring chromosomes in model plants such as Arabidopsis and tobacco. However, it takes a long time to complete this process, even in Arabidopsis. To overcome this issue, a new binary vector, pDLHC, has been developed to induce chromosomal rearrangements for a short time in rice. pDLHC has been found to be effective in the induction of deletions between two LoxPs in the T2 generation of "Nihon bare" expressing Ac TPase. pDLHC has potential for the efficient generation of various types of chromosomal rearrangements including deletions, inversions, translocations and artificial ring chromosomes in plants, and the detailed protocol for rice is described here.
