✦ Synopsis
Rhizosphere population characteristics of two cultivars of spring wheat (Tritieum aestivum L. emend Thell.), Rescue (R) and Cadet (C), and the related chromosome substitution lines, C-R5B and C-R5D, were investigated. R e p l a c e m e n t of the chromosome pair, 5 B, in Cadet with 5 B from Rescue made m a n y of the rhizosphere microbial characteristics of C-R5 B similar to or the same as those in the rhizosphere of the donor parent, Rescue. In contrast, substitution of the functionally related chromosome pair, 5D, did not cause marked changes in the rhizosphere microbial population, demonstrating the specificity of the plant's control over factors governing the rhizosphere microbial environment.
