Data from: Characterizing the reproductive transcriptomic correlates of acute dehydration in males in the desert-adapted rodent, Peromyscus eremicus
Background: The understanding of genomic and physiological mechanisms related to how organisms living in extreme environments survive and reproduce is an outstanding question facing evolutionary and organismal biologists. One interesting example of adaptation is related to the survival of mammals in deserts, where extreme water limitation is common. Research on desert rodent adaptations has focused predominantly on adaptations related to surviving dehydration, while potential reproductive physiology adaptations for acute and chronic dehydration have been relatively neglected. This study aims to explore the reproductive consequences of acute dehydration by utilizing RNAseq data in the desert-specialized cactus mouse (Peromyscus eremicus). Results: We exposed 22 male cactus mice to either acute dehydration or control (fully hydrated) treatment conditions, quasimapped testes-derived reads to a cactus mouse testes transcriptome, and then evaluated patterns of differential transcript and gene expression. Following statistical evaluation with multiple analytical pipelines, nine genes were consistently differentially expressed between the hydrated and dehydrated mice. We hypothesized that male cactus mice would exhibit minimal reproductive responses to dehydration; therefore, this low number of differentially expressed genes between treatments aligns with current perceptions of this species' extreme desert specialization. However, these differentially expressed genes include Insulin-like 3 (Insl3), a regulator of male fertility and testes descent, as well as the solute carriers Slc45a3 and Slc38a5, which are membrane transport proteins that may facilitate osmoregulation. Conclusions: These results suggest that in male cactus mice, acute dehydration may be linked to reproductive modulation via Insl3, but not through gene expression differences in the subset of other a priori tested reproductive hormones. Although water availability is a reproductive cue in desert-rodents exposed to chronic drought, potential reproductive modification via Insl3 in response to acute water-limitation is a result which is unexpected in an animal capable of surviving and successfully reproducing year-round without available external water sources. Indeed, this work highlights the critical need for integrative research that examines every facet of organismal adaptation, particularly in light of global climate change, which is predicted, amongst other things, to increase climate variability, thereby exposing desert animals more frequently to the acute drought conditions explored here.

Fig. 5 in Alterations in nepetalactone metabolism during polyethylene glycol (PEG)- induced dehydration stress in two Nepeta species
Fig. 5. The expression of selected transcription factors (COI1, JAZ3, MYC2, MYB and YABBY5) during PEG-induced dehydration stress in Nepeta rtanjensis (a) and N. argolica ssp. argolica (b) leaves at 1, 3 and 6 days of PEG treatment (DPT). Obtained values were normalized against NrGAPDH (a) and NaGAPDH (b) as the endogenous controls and presented relatively to their respective controls as calibrators. Results are presented as the means ± SD of three biological replicates. Asterisks (*) denote significant differences between PEG-treated and non-treated plants (unpaired t-test, *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001). Abbreviations: COI1- coronatine-insensitive 1, JAZ3-jasmonate ZIM-domain 3, MYC2- transcription factor Mouse-ear cress 2, MYB- transcription factor containing MYB-domain, YABBY5- YABBY5 transcription factor, GADPH- glyceraldehyde-3-phosphate dehydrogenase. Heatmaps of Pearson correlations of the absolute expression values for nepetalactone biosynthetic genes and transcription factors in N. rtanjensis (c) and N. argolica ssp. argolica (d). Correlation coefficients are shown in the lower triangle, while statistical significance (p <0.01) is marked with an asterisk at the appropriate positions in the upper triangle. Each square indicates the Pearson's correlation coefficient for a pair of genes, and the value of the correlation coefficient is represented by the intensity of yellow (positive correlations) or grey (negative correlations) in N. rtanjensis, or green (positive) and grey (negative) in N. argolica ssp. argolica, as indicated on the colour scale (for the interpretation of the references to colour in this Figure legend, the reader is referred to the web version of this article). The correlogram is ordered based on hierarchical cluster analysis (HCA) performed on a distance matrix (1- correlation matrix: minimal distance for absolutely positively correlated and maximal distance for absolutely negatively correlated gene expression). Cluster agglomeration was done using the single-linkage clustering method. The dendrograms are shown on heatmap sides. Abbreviations: GPPS- geranyl diphosphate synthase, GES- geraniol synthase, G8O- geraniol 8-oxidase, 8HGO- 8-hydroxygeraniol oxidoreductase, IS- iridoid synthase, NEPS- nepetalactol-related short-chain dehydrogenase, COI1- coronatine-insensitive 1, JAZ3-jasmonate ZIM-domain 3, MYC2- transcription factor Mouse-ear cress 2, MYBtranscription factor containing MYB-domain, YABBY5- YABBY5 transcription factor, DPT-days of PEG treatment.

Fig. 1 in Alterations in nepetalactone metabolism during polyethylene glycol (PEG)- induced dehydration stress in two Nepeta species
Fig. 1. The exposure of N. rtanjensis and N. argolica ssp. argolica shoots to PEG-induced dehydration stress under in vitro conditions resulted in the alterations of morphological and physiological parameters. As revealed by SEM of leaf surfaces of non-treated (a and c) and PEG-treated (b and d) N. rtanjensis and N. argolica ssp. argolica plants, peltate glandular trichomes (PGT) preserve their morphology, while stomata (white arrows) are closed in PEG-treated leaves at 6 days of PEG treatment (6DPT). Morphological differences between non-treated (e and g) and PEG-treated plants (f and h) at 6DPT indicated tissue dehydration and turgor loss in both model species. As a measure of dehydration stress, fresh weight (FW) of shoots (i and k) and their relative water content (RWC) (j and l) were traced throughout 6 days of PEG treatment in both N. rtanjensis and N. argolica ssp. argolica shoots. PEG-treated N. rtanjensis (yellow bars) and N. argolica ssp. argolica plants (green bars) are compared with their respective controls (grey bars) at 1DPT, 3DPT and 6DPT. Error bars represent SE of three biological replicates. Asterisks (*) denote significant differences between PEG-treated and non-treated plants (unpaired t-test, *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001). Abbreviations: DPT-days of PEG treatment. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)

Fig. 6. The relative expressions of the nepetalactone biosynthesis candidate genes (a) and of transcription factors (b) in trichomes and abraded leaves of Nepeta rtanjensis were normalized against 18S rRNA gene as endogenous control, and expressed relative to abraded leaves as calibrators.

Asterisks (*) denote significant differences between trichomes and depleted leaves (paired t-test, *p ≤ 0.05; **p ≤ 0.001; ***p ≤ 0.0001). Light micrograph of detached leaf trichomes (c) showing individual peltate glandular trichomes (PGT) and non-glandular mechanical trichomes (MT), bar = 100 μm. The light microscope (Leica DM2000, Germany) was used for the analysis of detached trichomes from N. rtanjensis leaves and image capturing was acquired with Software Leica IM1000 (Leica, Germany). Abbreviations: GPPSgeranyl diphosphate synthase, GES- geraniol synthase, G8O- geraniol 8-oxidase, 8HGO- 8-hydroxygeraniol oxidoreductase, IS- iridoid synthase, NEPS- nepetalactol-related short-chain dehydrogenase, COI1- coronatine-insensitive 1, JAZ3- jasmonate ZIM-domain 3, MYC2- transcription factor Mouse-ear cress 2, MYB- transcription factor containing MYB-domain, YABBY5- YABBY5 transcription factor.
