Distinct patterns of gene expression during regeneration and asexual reproduction in the annelid Pristina leidyi [PDF]
, 2022 Regeneration, the ability to replace lost body parts, is a widespread phenomenon in the animal kingdom often connected to asexual reproduction or fission, since the only difference between the two appears to be the stimulus that triggers them.

Oikos, EarlyView.Climate warming and plant invasions jointly alter alpine ecosystems, but the mechanisms underlying these interactions remain unclear. A key to predicting ecosystem vulnerability is whether native and invasive species can sustain performance as conditions warm.

Ecology and Evolution, 2021 We studied the impact of flooding and light availability gradients on sexual and asexual reproduction in Lindera melissifolia (Walt.) Blume, an endangered shrub found in floodplain forests of the Mississippi Alluvial Valley (MAV), USA.

Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico
PLANTS, PEOPLE, PLANET, EarlyView.Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

Scientific Reports, 2017 Ulocladium was thought to be a strictly asexual genus of filamentous fungi. However, Ulocladium strains were shown to possess both MAT1-1-1 and MAT1-2-1 genes as observed in homothallic filamentous Ascomycetes. Here, we demonstrate that the U.

Pest Management Science, EarlyView.Understanding how infection timing drives disease is essential for the development of fungicide resistance management strategies. For blackleg disease of canola, all infection timings can contribute to the following generation, therefore all fungicide applications have the ability to select for resistance.

Patterns of molecular evolution in a parthenogenic terrestrial isopod (Trichoniscus pusillus) [PDF]
PeerJThe “paradox of sex” refers to the question of why sexual reproduction is maintained in the wild, despite how costly it is compared to asexual reproduction. Because of these costs, one might expect nature to select for asexual reproduction, yet sex seems

Pest Management Science, EarlyView.The study has identified mutations in the voltage gated sodium channel of the English grain aphid (Sitobion avenae) at M918 and L932, which have not been previously reported in this species. Abstract BACKGROUND The grain aphid, Sitobion avenae Fabricius (Hemiptera: Aphididae), is a vector of yellow dwarf viruses and an important pest of cereals.

PLoS ONEMacroalgal populations often consist of free-living haploid (gametophyte) and diploid (sporophyte) stages. Various ecological studies have been conducted to examine the demographic diversity of haploid-diploid populations with regard to the dominant ...

A key role for sex chromosomes in the regulation of parthenogenesis in the brown alga Ectocarpus.
PLoS Genetics, 2019 Although evolutionary transitions from sexual to asexual reproduction are frequent in eukaryotes, the genetic bases of these shifts remain largely elusive.
