Kin competition accelerates experimental range expansion in an arthropod herbivore

Project description:In this study, we show that in a spider mite species, Tetranychus urticae, genetic changes do not drive experimental range expansions. We performed two experiments, each with two treatments, wherein mite populations were allowed to expand their habitat range. In a first experiment, we either replaced migrating females with females from the parental stock populations (Replacement From Stock) or left the migrants unmanipulated (Control). In a second experiment, we compared the range expansions of non-evolving, genetically inbred, populations (Iso) with those of evolving, genetically diverse, populations (Mix). Transcriptomic analysis supported other lines of evidence showing that experimental range expansion was driven by kin competition and not by genetic changes (see also Van Petegem et al, 2017). Only 21 differentially expressed genes were found.

Dicer-like proteins and their role in plant-herbivore interactions in Nicotiana attenuata

Project description:DICER-like proteins produce small RNAs that silence genes involved in development and defenses against viruses and pathogens. Which DCLs participate in plant-herbivore interactions remains unstudied. We identified four distinct DCL genes and stably silenced their expression by RNAi in Nicotiana attenuata, a model system for the study of plant-herbivore interactions. Silencing DCL1 expression was lethal to the plants. Manduca sexta larvae performed significantly better on ir-dcl3and ir-dcl4 plants, but not on ir-dcl2 plants compared to wild type plants. Phytohormones, defense metabolites and microarray analyses revealed that when DCL3 and DCL4 were silenced separately, herbivore resistance traits were regulated in distinctly different ways. Crossing of the lines revealed complex interactions in the patterns of regulation. Single ir-dcl4 and double ir-dcl2/ ir-dcl3 plants were impaired in JA accumulation, while JA-Ile was increased in ir-dcl3 plants. Ir-dcl3 and ir-dcl4 plants were impaired in nicotine accumulation; silencing DCL2 in combination with either DCL3 or DCL4 restored nicotine levels to those of WT. Trypsin proteinase inhibitor activity and transcripts were only silenced in ir-dcl3 plants. We conclude that DCL2/3/4 interact in a complex manner to regulate anti-herbivore defenses and that these interactions significantly complicate the already challenging task of understanding smRNA function in the regulation of biotic interactions.

Effect of drought on herbivore-induced plant gene expression: Population comparison for range limit inferences

Project description:Low elevation âtrailing edgeâ range margin populations typically face increases in both abiotic and biotic stressors that may contribute to range limit development. We hypothesize that selection may act on ABA and JA signaling pathways for more stable expression needed for range expansion, but that antagonistic crosstalk prevents their simultaneous co-option. To test this hypothesis, we compared high and low elevation populations of Boechera stricta that have diverged for constitutive levels of glucosinolate defenses and root:shoot ratios; neither population has high levels of both traits. If constraints imposed by antagonistic signaling underlies this divergence, one would predict that high constitutive levels of traits would coincide with lower plasticity. To test this prediction, we compared the genetically diverged populations in a double challenge drought-herbivory growth chamber experiment. Although a glucosinolate defense response to the generalist insect herbivore Spodoptera exigua was attenuated under drought conditions, the plastic defense response did not differ significantly between populations. Similarly, although several potential drought tolerance traits were measured, only stomata aperture behavior, as measured by carbon isotope ratio, was less plastic as predicted in the high elevation population. However, RNAseq results on a small subset of plants indicated differential expression of relevant genes between populations as predicted. We suggest that the ambiguity in our results comes from a weaker link between the pathways and the functional traits compared to transcripts.
