No Mate, No Problem: Molecular Mechanisms Involved in Parthenogenesis in the Cosmopolitan Earthworm Aporrectodea trapezoides (Annelida, Clitellata)

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Approximately, 40% of earthworm species can reproduce by parthenogenesis. This is the case for the cosmopolitan species, Aporrectodea trapezoides, although sexual forms have been described sporadically. We analyse the genotypes and microbiomes of 30 individuals from four localities where both forms appear in order to understand the ...

Transcriptional evidence of pluripotency during development of the leaf gall formed by grape phylloxera (Daktulosphaira vitifoliae)

open access: yesNew Phytologist, EarlyView.
Summary Galls are structures formed by plants in response to stimuli by parasitic insects. Because galls require altered gene expression to change cell fates, their initiation requires pluripotent or ‘reactive’ cells. We used RNA sequencing to test three hypotheses about potential sources of pluripotency in the leaf gall formed by grape phylloxera ...

Rhizobacteria prime the activation of plant defense and nutritional responses to suppress aphid populations on barley over time

open access: yesNew Phytologist, EarlyView.
Summary Interactions between plants and soil microbes are widespread and are documented to modulate plant–insect herbivore interactions. Still, it remains unclear how these shape the overall plant defense responses and the mechanisms in suppressing insect populations.

Invasive plants decrease arbuscular mycorrhizal fungal diversity and promote generalist fungal partners

open access: yesNew Phytologist, EarlyView.
Summary Invasion by exotic plants is a major threat to ecosystem biodiversity globally. Although mutualistic belowground associations can play a significant role in successful invasion, studies have shown mixed results regarding the effects of plant invasion on arbuscular mycorrhizal fungi (AMF). Here, we tested how exotic dominance (i.e.
