Premise of the study: Agricultural practices routinely create
opportunities for crops to hybridize with wild relatives, leading to crop
gene introgression into wild genomes. Conservationists typically worry
this introgression could lead to genetic homogenization of wild
populations, over and above the central concern of transgene escape.
Alternatively, viewing introgression as analogous to species invasion, we
suggest that increased genetic diversity may likewise be an undesirable
outcome. Methods: Here, we compare the sensitivity of conventional
population genetic metrics with species diversity indices as indicators of
the impact of gene flow on genetic diversity. We illustrate this novel
approach using multilocus genotype data (12 allozyme loci) from 10 wild
(Beta vulgaris subsp. maritima) and eight putative crop–wild hybrid beet
populations (B. vulgaris subsp. vulgaris × B. vulgaris subsp. maritima)
scattered throughout Europe. Results: Conventional population genetic
metrics mostly failed to detect shifts in genetic composition of putative
hybrid populations. By contrast, species diversity indices unambiguously
revealed increased genetic diversity in putative hybrid populations.
Discussion: We encourage other workers to explore the utility of our more
sensitive approach for risk assessment prior to the release of transgenic
crops, with a view toward widespread adoption of our method in studies
aimed at detecting allelic invasion.
