Complete and circularized genome sequences of five nitrogen-fixing sp. strains isolated from root nodules of peanut, , cultivated in Tunisia.

This manuscript reports the complete and circularized Oxford Nanopore Technologies (ONT) long read-based genome sequences of five nitrogen-fixing symbionts belonging to the genus , isolated from root nodules of peanut () grown on soil samples collected from Tunisia.

Natural genetic variation and negative density effects in plant-nematode interactions.

is a suitable host for phytoparasitic nematodes of the genus . Successful nematode infection leads to the formation of root galls. We tested for natural genetic variation and inoculation density effects on nematode reproductive success in the interaction between and .

Tempo of Degeneration Across Independently Evolved Nonrecombining Regions.

Recombination is beneficial over the long term, allowing more effective selection. Despite long-term advantages of recombination, local recombination suppression can evolve and lead to genomic degeneration, in particular on sex chromosomes. Here, we investigated the tempo of degeneration in nonrecombining regions, that is, the function curve for the accumulation of deleterious mutations over time, leveraging on 22 independent events of recombination suppression identified on mating-type chromosomes of anther-smut fungi, including newly identified ones.

Global urban environmental change drives adaptation in white clover.

Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors.

Draft Genome Sequences of Nitrogen-Fixing Bradyrhizobia Isolated from Root Nodules of Peanut, Arachis hypogaea, Cultivated in Southern Tunisia.

Here, we report the draft genome sequences of two nitrogen-fixing symbionts, sp. strain sGM-13 and sp. strain sBnM-33, isolated from root nodules of peanut grown on soil samples collected from two regions in South Tunisia.
