  3. Article ; Online: Evolution of mixed mating: Effects of among-parent variation in early-acting inbreeding depression coupled with overproduction of ovules.

    Abstract Theoretical models were developed to propose a new mechanism enhancing mixed mating (reproduction by both outcrossing and selfing) in hermaphroditic plants; mixed mating can be maintained if there exists among-parent variation in early-acting inbreeding depression in embryos and parents can replace dead embryos by overproduction of ovules. In the two main models developed, the number of embryos produced is allowed to evolve, parents may overproduce embryos, and among-parent variation in early-acting inbreeding depression does not exist or exists. I found that mixed mating does not evolve if among-parent variation in early-acting inbreeding depression does not exist, whereas it evolves if it exists. If the degree of early-acting inbreeding depression in embryos is variable among parents, parents with the same selfing strategy suffer different effects of early-acting inbreeding depression. Specifically, overproduction of embryos may be insufficient when inbreeding depression is severe but wasteful when it is weak. Hence, it is advantageous to produce a moderate number of embryos to reduce waste of resources. Mixed mating is then advantageous to avoid great reductions in seed number caused by massive loss of selfed embryos in cases of severe inbreeding depression.

    Abstract Frequencies of deleterious mutations are higher than expected in many plants. Here, by developing a two-locus two-allele model, I examine the effects of differential timing of the expression of deleterious mutations (two-stage effects) on the maintenance of mutations. I assume early- and late-acting loci to distinguish whether maintenance of mutations in populations with high selfing rates is explained better by two-stage effects of single mutations, or by separate mutations in both early- and late-acting loci. I found that, when ovules are overproduced, the stable frequency of early-acting mutations is higher if mutations also occur in a late-acting locus than if a late-acting mutation is lacking. The stable frequency of late-acting mutations is higher if mutations also occur in an early-acting locus than if an early-acting mutation is lacking. Selective interference does not account for these results because analyses in which the number of loci subject to mutations is equalized are included. Overproduction of ovules has little effect on maintenance if either early- or late-acting mutations are lacking, whereas when ovules are not overproduced, the two-stage effect does not enhance the maintenance of mutations. Hence, mutations occurring in both loci coupled with overproduction of ovules enhances the maintenance of mutations in populations with high selfing rates. The detailed mechanisms underlying the two-stage effect were also analyzed.

    Abstract The Cell Dome is a dome-shaped structure (diameter: 1 mm, height: 270 μm) with cells enclosed within a cavity, covered by a hemispherical hydrogel shell, and immobilized on a glass plate. Given that the cells within Cell Dome are in contact with the inner walls of the hydrogel shell, the properties of the shell are anticipated to influence cell behavior. To date, the impact of the hydrogel shell properties on the enclosed cells has not been investigated. In this study, we explored the effects of the cell adhesiveness of hydrogel shell on the behavior of enclosed cancer cells. Hydrogel shells with varying degrees of cell adhesiveness were fabricated using aqueous solutions containing either an alginate derivative with phenolic hydroxyl moieties exclusively or a mixture of alginate and gelatin derivatives with phenolic hydroxyl moieties. Hydrogel formation was mediated by horseradish peroxidase. We used the HeLa human cervical cancer cell line, which expresses fucci2, a cell cycle marker, to observe cell behavior. Cells cultured in hydrogel shells with cell adhesiveness proliferated along the inner wall of the hydrogel shell. Conversely, cells in hydrogel shells without cell adhesiveness grew uniformly at the bottom of the cavities. Furthermore, cells in non-adhesive hydrogel shells had a higher percentage of cells in the G1/G0 phase compared to those in adhesive shells and exhibited increased resistance to mitomycin hydrochloride when the cavities became filled with cells. These results highlight the need to consider the cell adhesiveness of the hydrogel shell when selecting materials for constructing Cell Dome.

    Abstract High estimates of inbreeding depression have been obtained in many plant populations with high selfing rates. However, deleterious mutations might be purged from such populations as a result of selfing. I developed a simulation model assuming the presence of mutations at two sets of loci, namely, early- and late-acting loci, and the selective abortion of embryos coupled with ovule overproduction. In the model, early-acting loci are expressed during embryo initiation, and less vigorous embryos are aborted. Late-acting loci are expressed after selective abortion ends; the surviving embryos (seeds) compete, and some of them form the next generation. If mutations are allowed to occur in both early- and late-acting loci, both types increase in frequency in populations with high selfing rates. However, this phenomenon does not occur if mutations occur only in the early- or only in the late-acting loci. Consistent results are observed even if the total number of loci in which mutations are allowed to occur is the same for simulations with both early- and late-acting loci, only early-acting loci, or only late-acting loci, indicating that the presence of both types of loci is the causal factor. Thus, the two-stage effect, or occurrence of both early- and late-acting mutations, promotes the maintenance of these mutations in populations with high selfing rates.

    Abstract Intraspecific variations in pollen morphological traits are poorly studied. Interspecific variations are often associated with pollination systems and pollinator types. Altitudinal environmental changes, which can influence local pollinator assemblages, provide opportunities to explore differentiation in pollen traits of a single species over short distances. The aim of this study is to examine intraspecific variations in pollen traits of an insect-pollinated shrub, Weigela hortensis (Caprifoliaceae), along an altitudinal gradient. Pollen spine phenotypes (length, number and density), pollen diameter, lipid mass (pollenkitt) around pollen grains, pollen production per flower and pollinator assemblages were compared at four sites at different altitudes. Spine length and the spine length/diameter ratio of pollen grains were greater at higher altitudes but not correlated with flower or plant size. Spine number and density increased as flower size increased, and pollen lipid mass decreased as plant size increased. Bees were the predominant pollinators at low-altitude sites whereas flies, specifically Oligoneura spp. (Acroceridae), increased in relative abundance with increasing altitude. The results of this study suggest that the increase in spine length with altitude was the result of selection favouring longer spines at higher-altitude sites and/or shorter spines at lower-altitude sites. The altitudinal variation in selection pressure on spine length could reflect changes in local pollinator assemblages with altitude.

    Abstract Flowers cluster at various spatial scales, so pollinators use information from multiple scales when foraging in natural plant populations. Little is known about the effects of interactions between scales or their relative strength. We examined bumblebee foraging behaviour in a natural population of Salvia nipponica in 10 and 7 patches in 2019 and 2020, respectively. We recorded within-patch factors (display size of racemes and local open raceme densities) and patch-level factors (patch size and distance from the nearest patch) and analysed their relationships with pollinator behaviour. The numbers of visits per raceme and flower were mainly affected by the interaction of patch size and raceme density; they were higher in locations with lower raceme density in larger patches. The ratio of flowers visited to all open flowers in a raceme during a raceme visit, which relates to a bumblebee's choice to leave a raceme, was mainly affected by the interaction of display size and local open raceme density; in 2019 it was higher in racemes with smaller display sizes, while in 2020 the strength and direction of the relationship depended on the open raceme density. These results suggest that pollinators relied on the sizes of flower clusters at different spatial scales when visiting and leaving racemes and adjusted their responses to the sizes of flower clusters depending on the distances between clusters. Therefore, it is important to evaluate factors at various spatial scales and their interactions to fully understand pollinator behaviour in natural plant populations.
