Organisms possess photoperiodic timing mechanisms to detect variations in day length and temperature as the seasons progress. The nature of molecular interpreting signaling these environmental changes elicit downstream neuroendocrine physiological responses are just starting emerge. Here, we demonstrate that, Drosophila melanogaster, EYES ABSENT (EYA) acts a seasonal sensor by trigger appropriate responses. We observed that tissue-specific genetic manipulation eya expression is sufficient...
There is a dynamic reciprocity between plants and their environment: soil physiochemical properties influence plant morphology metabolism, root exudates shape the environment surrounding roots. Here, we investigate reproducibility of trait changes in response to three growth environments. We utilized fabricated ecosystem (EcoFAB) devices grow model grass Brachypodium distachyon distinct media across four laboratories: phosphate-sufficient -deficient mineral allowed assessment effects...
Abstract Studying how novel phenotypes originate and evolve is fundamental to the field of evolutionary biology as it allows us understand organismal diversity generated maintained. However, determining basis challenging involves orchestrated changes at multiple biological levels. Here, we aim overcome this challenge by using a comparative species framework combining behavioral, gene expression, genomic analyses egg-laying substrate-choice behavior invasive pest Drosophila suzukii. First,...
Beneficial plant-microbe interactions offer a sustainable biological solution with the potential to boost low-input food and bioenergy production. A better mechanistic understanding of these complex will be crucial improving plant production as well performing basic ecological studies investigating plant-soil-microbe interactions. Here, detailed description for ecosystem fabrication is presented, using widely available 3D printing technologies, create controlled laboratory habitats (EcoFABs)...
Abstract Drosophila suzukii, or spotted-wing drosophila, is now an established pest in many parts of the world, causing significant damage to numerous fruit crop industries. Native East Asia, D. suzukii infestations started United States a decade ago, occupying wide range climates. To better understand invasion ecology this pest, knowledge past migration events, population structure, and genetic diversity needed. In study, we sequenced whole genomes 237 individual flies collected across...

Abstract Drosophila suzukii lay eggs in soft-skinned, ripening fruits, making this insect a serious threat to berry production. Since its 2008 introduction into North America, growers have used insecticides, such as pyrethroids and spinosads, the primary approach for D. management, resulting development of insecticide resistance pest. This study sought identify molecular mechanisms conferring these populations. We sequenced transcriptomes two pyrethroid- spinosad-resistant isofemale lines....
Abstract Tuta absoluta is one of the largest threats to tomato agriculture worldwide. Native South America, it has rapidly spread throughout Europe, Africa, and Asia over past two decades. To understand how T. been so successful improve containment strategies, high-quality genomic resources an understanding population history are critical. Here, we describe a highly contiguous annotated genome assembly, as well genome-wide analysis samples collected across Latin America. The new assembly L50...
There is a dynamic reciprocity between plants and their environment: On one hand, the physiochemical properties of soil influence plant morphology metabolism, while on other, root exudates shape environment surrounding roots. Here, we investigate both these aspects as well reproducibility responses across laboratories. The model grass Brachypodium distachyon was grown in phosphate-sufficient phosphate-deficient mineral media, sterile extract, within fabricated ecosystem (EcoFAB) devices four...

Abstract The tomato pest Phthorimaea absoluta Meyrick is highly invasive but has not yet invaded North America. However, several morphologically similar species are already present, making detection of P. presence and invasion challenging. We designed a quantitative PCR molecular diagnostic to differentiate absoluta, operculella (Zeller), or Keiferia lycopersicella (Walsingham) (Lepidoptera: Gelechiidae) DNA. Additionally, we developed an RPA-Cas12a that allows for the isothermal DNA,...
