TL;DR: The application of a new gene-based strategy for sequencing the wheat mitochondrial genome shows its structure to be a 452 528 bp circular molecule, and provides nucleotide-level evidence of intra-molecular recombination.

TL;DR: Variation in repeat number at 20 microsatellite loci of Arabidopsis thaliana was studied in a worldwide sample of 42 ecotypes to investigate the pattern and level of polymorphism in repetitive sequences in natural plant populations.

TL;DR: Codon usage in nuclear genes of four monocot and three dicot species was analyzed to find general patterns in codon choice of plant species, and codon bias was correlated with GC content at the third codon position.

TL;DR: In this article, the authors investigated phylogenetic relationships among plasmons in Triticum and Aegilops, and made PCR-single-strand conformational polymorphism (PCR-SSCP) analyses of 14.0-kb chloroplast (ct) and 13.7-kb mtDNA regions that were isolated from 46 alloplasmic wheat lines and one euplasmic line.

TL;DR: A neighbor-joining tree was constructed on the basis of the AFLP variation and has a star-like topology and shows no clear association between ecotype and geographic origin, suggesting a recent spread of this plant species and limited migration between its habitats.
