Supplementary Files and Data of 'Live-bearing cockroach genome reveals convergent evolutionary mechanisms linked to viviparity in insects and beyond'

Live birth (viviparity) has arisen repeatedly and independently among animals. We sequenced the genome and transcriptome of the viviparous Pacific beetle-mimic cockroach and performed comparative analyses with two other viviparous insect lineages, tsetse flies and aphids, to unravel the basis underlying the transition to viviparity in insects. We identified pathways undergoing adaptive evolution for insects, involved in uro-genital remodeling, tracheal system, heart development, and nutrient metabolism. Transcriptomic analysis in the cockroach and tsetse viviparity reveals that uterine remodeling and nutrient production are increased and the immune response is altered during pregnancy, facilitating structural and physiological changes to accommodate and nourish the progeny. These patterns of convergent evolution of viviparity among insects, together with similar adaptive mechanisms identified among vertebrates, highlight that the transition to viviparity requires changes in uro-genital remodeling, enhanced tracheal and heart development (corresponding to angiogenesis in vertebrates), nutrient metabolism, and shifted immunity in all animal systems.

Dietary protein and sodium co-limit cockroach growth and reproduction, 2019-2020

The dataset contains information on a feeding study done on the cockroach species Blaptica dubia. Cockroaches were assigned to a combination of treatments that contained two levels of protein (low 21% or high 27%) and three levels of sodium (low 0.06%, medium 0.15%, or high 0.3%). Cockroaches were reared until reaching maturity, growth measurements were taken every 14 days. Individuals from the same treatment were then paired to reproduce their first clutch of offspring.

Phylogenomics and deep convergence in cockroach hind-wing morphology

Despite regular advances in Blattodea systematics, several relationships remain controversial or untested in formal phylogenetic reconstructions. This common situation for understudied metazoan groups limits our power to answer questions about phenotypic evolution. In this study, we infer the evolutionary history of Blattodea using newly sampled taxa that improve phylogenetic resolution while also illuminating the evolutionary history of an unusual phenotype—the apically folded hind-wing. Taxa newly sequenced include those with a hind-wing apical fold (Anaplecta pulchella, A. pygmaea, A. sp. cf. malaysensis, Diplopterina parva, Prosoplecta semperi, Anaplectoidea klossi, and Oulopteryx illuminata sp. nov. that we describe herein, including its male genitalia) and other rare taxa (Dipteretrum hamstroemi, Duchailluia togoensis, Lauraesilpha mearetoi, Buboblatta vlasaki). The phylogenetic design utilizes 41 genes over 91 species in total, analyzed in a maximum likelihood and coalescent framework. To quantify the phylogenetic uncertainty of the analysis, support for various topologies is assessed. We find unambiguous support for the surprising position of Neotropical Oulopteryx (Oulopterygidae) as sister to New Caledonian/Australian Tryonicidae. This, and other phylogenetic findings, reveal that the apically folded hind-wing may have arisen nine times in Blattodea. Further investigations are needed, notably with an increased taxonomic sampling, to demonstrate stronger support for the placement of rogue taxa (e.g., Anaplecta) and to investigate the evolutionary correlates of wing evolution.

Data for dating in the dark: Elevated substitution rates in cave cockroaches (Blattodea: Nocticolidae) have negative impacts on molecular date estimates

Rates of nucleotide substitution vary substantially across the Tree of Life, with potentially confounding effects on phylogenetic and evolutionary analyses. A large acceleration in mitochondrial substitution rate occurs in the cockroach family Nocticolidae, which predominantly inhabit subterranean environments. To evaluate the impacts of this among-lineage rate heterogeneity on estimates of phylogenetic relationships and evolutionary timescales, we analysed nuclear ultraconserved elements (UCEs) and mitochondrial genomes from nocticolids and other cockroaches. Substitution rates were substantially elevated in nocticolid lineages compared with other cockroaches, especially in mitochondrial protein-coding genes. This disparity in evolutionary rates is likely to have led to different evolutionary relationships being supported by mitochondrial genomes and UCE loci. Furthermore, analyses using relaxed-clock models inferred much deeper divergence times compared with a flexible local clock. Our phylogenetic analysis of UCEs, which is the first genome-scale study to include all nine major cockroach families, unites Corydiidae and Nocticolidae and places Anaplectidae as the sister lineage to the rest of Blattoidea. We uncover an extraordinary level of genetic divergence in Nocticolidae, including two highly distinct clades that separated ~115 million years ago despite both containing representatives of the genus Nocticola. The results of our study highlight the potential impacts of high among-lineage rate variation on estimates of phylogenetic relationships and evolutionary timescales.
