C. Hartmann et al., Nuclear control of mitochondrial genome reorganization characterized usingcultured cells of ditelosomic and nullisomic-tetrasomic wheat lines, CURR GENET, 38(3), 2000, pp. 156-162
In vitro-mediated reorganization of the mitochondrial genome is governed by
information contained in the nuclear genome. Here we show, from the study
of tissue cultures initiated from an almost complete collection of diteloso
mic and nullisomic-tetrasomic wheat lines, that nuclear control of the mito
chondrial genome structure is a highly complex process. Whereas information
responsible for the amplification of defined molecular configurations has
been found to be located in either a single or a few chromosomal arms, othe
r rearrangements such as changes in the relative amounts of interconverting
subgenomic structures are governed by a number of genes scattered over mos
t of the wheat chromosomes.
