Gene Family Evolution Reflects Adaptation to Soil Environmental Stressors in the Genome of the Collembolan Orchesella cincta
Collembola (springtails) are detritivorous hexapods that inhabit the soil and its litter layer. The ecology of the springtail Orchesella cincta is extensively studied in the context of adaptation to anthropogenically disturbed areas. Here, we present a draft genome of an O. cincta reference strain with an estimated size of 286.8 Mbp, containing 20,249 genes. In total, 446 gene families are expa...
متن کاملVariation, selection and heritability of thermal reaction norms for juvenile growth in Orchesella cincta (Collembola: Entomobryidae)
Genetic variation for thermal plasticity plays an important role in the success or failure of a species with respect to the colonization of different thermal habitats and the ability to deal with climatic change. The aim of this paper is to study the relative contribution of the additive and non-additive components of genetic variation for the slope of the temperature reaction norm for juvenile...
متن کاملMicro-evolution of toxicant tolerance: from single genes to the genome’s tangled bank
Two case-studies published 55 years ago became textbook examples of evolution in action: DDT resistance in houseflies (Busvine) and the rise of melanic forms of the peppered moth (Kettlewell). Now, many years later, molecular studies have elucidated in detail the mechanisms conferring resistance. In this paper we focus on the case of metal tolerance in a soil-living arthropod, Orchesella cincta...
متن کاملLipid composition and extreme temperature tolerance following exposure to fluctuating temperatures in Orchesella cincta
Ectotherms commonly adjust storage and membrane lipid composition to ambient temperature to counteract detrimental thermal effects on lipid fluidity. The effect of repeated temperature fluctuations on fatty acid composition and thermal tolerance was investigated. We exposed Orchesella cincta to two constant temperatures (5ºC and 20°C), and a continuously fluctuating treatment (5ºC/20ºC every tw...
متن کاملDesaturase expression in response to temperature in the soil arthropod Orchesella cincta
To anticipate the effects of climate change, one needs mechanistic knowledge on the biochemical and physiological pathways underlying temperature plasticity. Remodelling of cell membrane fatty acids in response to changes in environmental temperature by ectotherms helps to maintain membrane function. We investigated the RNA expression of genes coding for various desaturase enzymes, which are be...
