Geraniaceae plastid genomes are highly rearranged, and each of the four genera already sequenced in the family has a distinct genome organization. This study reports plastid genome sequences of six additional species, Francoa sonchifolia, Melianthus villosus, and Viviania marifolia from Geraniales, and Pelargonium alternans, California macrophylla, and Hypseocharis bilobata from Geraniaceae. These genome sequences, combined with previously published species, provide sufficient taxon sampling to reconstruct the ancestral plastid genome organization of Geraniaceae and the rearrangements unique to each genus. The ancestral plastid genome of Geraniaceae has a 4 kb inversion and a reduced, Pelargonium-like small single copy region. Our ancestral genome reconstruction suggests that a few minor rearrangements occurred in the stem branch of Geraniaceae followed by independent rearrangements in each genus. The genomic comparison demonstrates that a series of inverted repeat boundary shifts and inversions played a major role in shaping genome organization in the family. The distribution of repeats is strongly associated with breakpoints in the rearranged genomes, and the proportion and the number of large repeats (>20 bp and >60 bp) are significantly correlated with the degree of genome rearrangements. Increases in the degree of plastid genome rearrangements are correlated with the acceleration in nonsynonymous substitution rates (dN) but not with synonymous substitution rates (dS). Possible mechanisms that might contribute to this correlation, including DNA repair system and selection, are discussed.

The Martinsburg Initiative (TMI) is a community-based model developed in Martinsburg, West Virginia, that implements a comprehensive approach to adverse childhood experiences and substance use prevention and mitigation by leveraging partnerships in public health and health care, public safety, and education. TMI receives coordinated federal funding and technical assistance from the Centers for Disease Control and Prevention, the Washington-Baltimore High Intensity Drug Trafficking Agency, and the National Association of County and City Health Officials to integrate evidence-based and promising strategies. It advances such strategies by translating them for implementation within the community, evaluating the reach and potential impact of the model, and by engaging key stakeholders. Preliminary results describing program reach and short-term outcomes collected for a subset of the interventions during implementation are presented. The model uses touchpoints across multiple community sectors in the city of Martinsburg to break the cycle of trauma and substance use across the life span.
