Abstract Detail



A Colloquium Honoring Leslie D. Gottlieb

Weeden, Norman [1], Henry, Amanda [2], Gottlieb, Leslie [3].

The genetic basis of several critical differences between the bee-pollinated Clarkia concinna and its hawk-moth pollinated derivative C. breweri.

Clarkia concinna and C. breweri are known to possess a progenitor/derived species relationship and can be intercrossed despite considerable morphological divergence, particularly in those traits associated with the different pollinators of the two species. C. concinna flowers open in the morning, are scentless, and possess slender, striped petals, pink sepals and a thread-like filament. C. breweri flowers open in the evening and possess a pleasant aroma, broad petals, greenish sepals, and a clavate filament. We analyzed the segregation of these and other characters in F3 families from a cross between the two species and compared the observed segregation patterns with those of DNA markers on a linkage map constructed for this population. Most of the species differences examined appeared to be controlled by relatively few genes, although genes with minor effects could not be resolved in the relatively small population (95 F3 families). The primary gene affecting scent was confirmed to be linalool synthase.
