Reproductive Evolution: Symptom of a Selfing Syndrome
نویسنده
چکیده
In the nematode Caenorhabditis elegans, a single gene (plg-1) encodes the dominant protein found in mating plugs - a means of inhibiting multiple matings. Naturally occurring loss of plg-1 function results in males that fail to deposit mating plugs - a manifestation of relaxed sexual selection since the evolution of self-fertilization in this species.

Evolution of the selfing syndrome in Ipomoea
Plants that are highly selfing typically exhibit a suite of morphological traits termed a "selfing syndrome," including reduced corollas and reproductive structures, loss of corolla pigmentation, little anther-stigma separation, and a lower pollen/ovule (P/O) ratio. While it is typically assumed that these changes are adaptive, few attempts have been made to determine whether they result from t...
متن کاملCis-Regulatory Changes Associated with a Recent Mating System Shift and Floral Adaptation in Capsella
The selfing syndrome constitutes a suite of floral and reproductive trait changes that have evolved repeatedly across many evolutionary lineages in response to the shift to selfing. Convergent evolution of the selfing syndrome suggests that these changes are adaptive, yet our understanding of the detailed molecular genetic basis of the selfing syndrome remains limited. Here, we investigate the ...
متن کاملSexually antagonistic polymorphism in simultaneous hermaphrodites.
In hermaphrodites, pleiotropic genetic trade-offs between female and male reproductive functions can lead to sexually antagonistic (SA) selection, where individual alleles have conflicting fitness effects on each sex function. Although an extensive theory of SA selection exists for dioecious species, these results have not been generalized to hermaphrodites. We develop population genetic models...
متن کاملThe relative importance of reproductive assurance and automatic selection as hypotheses for the evolution of self-fertilization.
BACKGROUND The field of plant mating-system evolution has long been interested in understanding why selfing evolves from outcrossing. Many possible mechanisms drive this evolutionary trend, but most research has focused upon the transmission advantage of selfing and its ability to provide reproductive assurance when cross-pollination is uncertain. We discuss the shared conceptual framework of t...
متن کاملDemographic signatures accompanying the evolution of selfing in Leavenworthia alabamica.
The evolution of selfing from outcrossing is a common transition, yet little is known about the mutations and selective factors that promote this shift. In the mustard family, single-locus self-incompatibility (SI) enforces outcrossing. In this study, we test whether mutations causing self-compatibility (SC) are linked to the self-incompatibility locus (S-locus) in Leavenworthia alabamica, a sp...
