Data from: Mitochondrial phylogenomics of Hemiptera reveals adaptive innovations driving the diversification of true bugs

Hu Li, , Eric G. Chapman, Daniel Burkhardt, Fan Song, Pei Jiang, Jinpeng Liu, Xuguo Zhou, Wanzhi Cai & John M. Leavengood
Hemiptera, the largest non-holometabolous order of insects, represents ~7% of metazoan diversity. With extraordinary life histories and highly specialized morphological adaptations, hemipterans have exploited diverse habitats and food sources through ~300 million years of evolution. To elucidate the phylogeny and evolutionary history of Hemiptera, we carried out the most comprehensive mitogenomics analysis on the richest taxon sampling to date covering all the suborders and infraorders, including 34 newly sequenced and 94 published mitogenomes. With optimized...

Data from: Light sensing by opsins and fungal ecology: NOP-1 modulates entry into sexual reproduction in response to environmental cues

Zheng Wang, Junrui Wang, Ning Li, Jigang Li, Frances Trail, Jay C. Dunlap & Jeffrey P. Townsend
Understanding the genetic basis of the switch from asexual to sexual lifestyles in response to sometimes rapid environmental changes is one of the major challenges in fungal ecology. Light appears to play a critical role in the asexual–sexual switch—but fungal genomes harbour diverse light sensors. Fungal opsins are homologous to bacterial green-light-sensory rhodopsins, and their organismal functions in fungi have not been well understood. Three of these opsin-like proteins were widely distributed across fungal genomes,...

Data from: Cumulative and partially recoverable impacts of nitrogen addition on a temperate steppe

Tianxiang Hao, Ling Song, Keith Goulding, Fusuo Zhang & Xuejun Liu
Atmospheric nitrogen (N) deposition has been shown to decrease biodiversity and change nutrient cycles in terrestrial ecosystems. However, our understanding of ecological responses to chronic N addition and ecological recovery from N enrichment to grassland is limited. Here we present evidence from an 11-year grassland experiment with a range of N addition rates (0, 30, 60, 120, 240, and 480 kg N ha−1 yr−1) in Inner Mongolia, China. Chronic N addition led to a reduction...

Data from: High genetic diversity in the offshore island populations of the tephritid fruit fly Bactrocera dorsalis

Chunyan Yi, Chunyan Zheng, Ling Zeng & Yijuan Xu
Background: Geographic isolation is an important factor that limit species dispersal and thereby affects genetic diversity. Because islands are often small and surrounded by a natural water barrier to dispersal, they generally form discrete isolated habitats. Therefore, islands may play a key role in the distribution of the genetic diversity of insects, including flies. Results: To characterize the genetic structure of island populations of Bactrocera dorsalis, we analyzed a dataset containing both microsatellite and mtDNA...

Data from: Arabidopsis MKK10-MPK6 mediates red-light-regulated opening of seedling cotyledons through phosphorylation of PIF3

Xiaoyun Xin, Wenhao Chen, Bo Wang, Fan Zhu, Yuan Li, Hailian Yang, Jigang Li & Dongtao Ren
Photomorphogenesis is an important process in which seedlings emerge from soil and begin autotrophic growth. Photomorphogenesis mechanisms include light signal perception, signal transduction, and the modulation of light-responsive genes expression, ultimately leading to cellular and developmental changes. Phytochrome-interacting factors (PIFs) play pivotal roles in negatively regulating photomorphogenesis. Light-induced activation of phytochromes triggers the rapid phosphorylation and degradation of PIFs, but the kinases responsible for the phosphorylation of PIFs are largely unknown. Here, we show that...

Data from: Extreme polyandry aids the establishment of invasive populations of a social insect

Guiling Ding, Huanli Xu, Benjamin P. Oldroyd & Rosalyn S. Gloag
Although monandry is believed to have facilitated the evolution of eusociality, many highly eusocial insects have since evolved extreme polyandry. The transition to extreme polyandry was likely driven by the benefits of within-colony genetic variance to task specialization and/or disease resistance, but the extent to which it confers secondary benefits, once evolved, is unclear. Here we investigate the consequences of extreme polyandry on the invasive potential of the Asian honey bee, Apis cerana. In honey...

Data from: Facilitation among plants can accelerate density-dependent mortality and steepen self-thinning lines in stressful environments

Wei-Ping Zhang, Xin Jia & Gen-Xuan Wang
The speed and slope of plant self-thinning are all affected by plant-plant interactions across environmental gradients. Possible mechanisms driving the self-thinning dynamics include the relative strength of root vs. shoot competition, and the interplay between competition and facilitation. Although these mechanisms often act in concert, their relative importance has not yet been fully explored. We used both a one-layer and a two-layer zone-of-influence (ZOI) model to examine how competition and facilitation drive self-thinning across stress...

Data from: Genome-wide assessment of population structure and genetic diversity and development of a core germplasm set for sweet potato based on specific length amplified fragment (SLAF) sequencing

Wenjin Su, Lianjun Wang, Jian Lei, Shasha Chai, Yi Liu, Yuanyuan Yang, Xinsun Yang & Chunhai Jiao
Sweet potato, Ipomoea batatas (L.) Lam., is an important food crop that is cultivated worldwide. However, no genome-wide assessment of the genetic diversity of sweet potato has been reported to date. In the present study, the population structure and genetic diversity of 197 sweet potato accessions most of which were from China were assessed using 62,363 SNPs. A model-based structure analysis divided the accessions into three groups: group 1, group 2 and group 3. The...
