The crude, partly burned wooden cross planted behind it was given to the museum by the local F.B.I. office.
Our first view of the Okefenokee Swamp, where the story takes place, is centered on a crude wooden cross, planted in a shallow channel and topped with a human skull.
Linkage of HWA1 with RM5349 and RM224 was confirmed by adding the 82 three-way cross plants (Fig. 3).
Examination of the two cross plants revealed that the phenotypes of abi4-1/35S abi4-1/35Snd abi5-1/35S::MIR394a plands abi5-1/35S abi5-1/35S to the phenotype of abi4-1 and abi5-1 plants, respectively [ 6, 26, 27].
We compared fully crossed plant - soil inoculum combinations from different source populations within the regions by growing plants in increasingly distant 'away soils'.
This pattern of population structure has been previously reported in other out crossing plant species [ 27, 28].
The cluster analysis suggests that genetic distance among crossed plant populations is higher between Pampean and Gulf, and intermediate between Pampean and Marshall.
Conventional plant-breeding involving selection of plants for specific traits has utilized both intraspecies and interspecies crosses, plant hybrid production, chemical and X-ray mutagenesis, embryo rescue, and other techniques [ 12, 13].
Five interspecific hybrids were obtained by crossing plant 03 as female with one plant of accession ClAlo 943 of S. chacoense as male; the latter was provided by the Potato and Forages Germplasm Bank, EEA Balcarce, INTA, Argentina.
