Data for: Trinity assembled transcriptome of a Eurasian (Myriophyllum spicatum) and a hybrid (M. spicatum × M. sibiricum) genotype of watermilfoil
<p>Aquatic plant managers frequently treat Eurasian watermilfoil (<em>Myriophyllum spicatum</em> L.; EWM) and hybrid watermilfoil (<em>Myriophyllum spicatum</em> L. × <em>Myriophyllum sibiricum</em> Komarov) with 2,4-dichlorophenoxyacetic acid (2,4-D) herbicide. However, watermilfoil genotypes can differ in their response to 2,4-D. In this study, we compared facultative and constitutive gene expression differences for two watermilfoil genotypes (one Eurasian and one hybrid) that differ in their sensitivity to 2,4-D. To do this, we compared between control and 0.5mg L-1 2,4-D treated plants at four time points after treatment. We also assembled the first de novo watermilfoil transcriptome. We found that while qualitatively similar, the facultative transcriptional response of the EWM genotype to 2,4-D treatment was much stronger than the hybrid genotype, indicated by a greater number and log-fold-change of differentially expressed genes at all time points after treatment. Further, we found that the EWM and hybrid genotype differed in their 9-cis-epoxycarotenoid dioxygenase (NCED) and abscisic acid (ABA) gene response, and that there was a greater amount of photosynthesis gene downregulation (both in number and log-fold-change) in the EWM than the hybrid genotype. At the constitutive level, overall, the hybrid expressed genes at a higher level than the EWM genotype, but not the genes of the 2,4-D response pathway. These differences in gene expression match with the degree of phenotypic difference in growth observed between these genotypes when exposed to 2,4-D. The hybrid genotype used here mitigates the effects of 2,4-D treatment better than the EWM genotype at both the molecular and phenotypic level. More study is needed to understand the mechanism(s) of mitigation and whether this is a cause of hybridity, or the specific genotypic backgrounds used here.</p>

North Temperate Lakes site, station Trout Lake, study of plant biomass of Myriophyllum verticillatum in units of gramsPerSquareMeter on a yearly timescale
The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from North Temperate Lakes (NTL) contains plant biomass of Myriophyllum verticillatum measurements in gramsPerSquareMeter units and were aggregated to a yearly timescale.

Experimental data (Biomass, RGR, LDMC, SLA etc.) of Myriophyllum spicatum and Cabomba caroliniana
<p>The synergy between climate change, eutrophication and biological invasion is threatening for native submerged plants in many ways. The response of submerged plants to these changes is a key factor that determines the outcome of biological invasion. In order to explain the invasion successes, we investigated the combined effects of climate change and eutrophication related environmental factors (temperature, light, nutrients) on the hard trait responses of a native and an alien submerged species (<i>Myriophyllum spicatum</i>, <i>Cabomba caroliniana</i>) from the same growth form. In a factorial design we cultivated the two species in aquaria containing low and high nutrient concentrations and incubated at four light intensities under two temperature levels. We used invasion related four functional traits (relative growth rate, specific leaf area, leaf dry matter content, nitrogen to carbon ratio) to measure the environmental response of the species. We calculated plasticity indexes to express the hard trait differences between species. The alien species <i>C. caroliniana</i> showed significantly higher relative growth rate and specific leaf area than <i>M. spicatum</i> especially under low light intesity indicating that <i>Cabomba</i> is much more shade tolerant.<b> </b>Elevated temperature resulted in higher specific leaf area and reduced dry mass content for <i>C. caroliniana </i>indicating that<i> Cabomba </i>may have higher invasion success. <i>M. spicatum</i> showed significantly higher leaf dry matter content than <i>C. caroliniana</i>. Chemical analyses of the plant tissue revealed that although <i>M. spicatum</i> showed significantly higher N:C molar ratio, nonetheless the daily nitrogen uptake of <i>C. caroliniana</i> was three times faster than that of <i>M. spicatum</i>. Results indicated that due to its higher shade tolerance and nitrogen uptake capacity, <i>Cabomba</i> has greater invasion success with increasing temperature combined with low light levels.</p>
