Characterization and microsatellite marker development for Geosmithia obscura, a common bark and ambrosia beetle associate
<p class="MsoNormal"><strong><span>Background. </span></strong><span>S</span><span>ymbioses between <em>Geosmithia</em> fungi and </span><span>wood-boring and bark beetles</span><span> seldom result in disease induction within the plant host. Yet exceptions exist such as <em>Geosmithia</em> <em>morbida</em>, the causal agent of Thousand Cankers Disease (TCD) of walnuts and wingnuts and <em>Geosmithia</em> sp. 41, the causal agent of Foamy Bark Canker disease of oaks. Isolates of<em> G. obscura </em>were recovered from black walnut trees in eastern Tennessee and<em> </em>at least one isolate induced cankers following artificial inoculation. Due to the putative pathogenicity and lack of recovery of <em>G. obscura </em>from natural lesions, a molecular diagnostic screening tool was developed using microsatellite markers mined from the <em>G. obscura </em>genome.</span></p> <p class="MsoNormal"><strong><span>Results. </span></strong><span>A total of 3,256 candidate microsatellite markers were identified (2236, 789, 137 di-, tri-, and tetra- motifs were identified, respectively), with 2011, 703, 101 di-, tri-, and tetra- motifs containing markers with primers. From these, 75 microsatellite markers were randomly selected, screened, and optimized, resulting in 28 polymorphic markers that yielded single, consistently recovered bands which were used in downstream analyses. Five of these microsatellite markers were found to be specific to <em>G. obscura </em>and did not cross-amplify into other, closely related species. Although the remaining tested markers could be useful, they cross-amplified within different <em>Geosmithia</em> species, making them not reliable for <em>G. obscura </em>detection.</span></p> <p class="MsoNormal"><strong><span>Conclusion.</span></strong><span> Five novel microsatellite markers (GOBS9, GOBS10, GOBS41, GOBS43, GOBS50) were developed based on <em>G. obscura</em> genome. These species-specific microsatellite markers are available as a tool for use in molecular diagnostics and can assist future surveillance studies.</span></p>
Provenance rather than nitrogen addition dominate the phenotypes and plasticity of Ambrosia artemisiifolia in China
<p><span>Phenotypic plasticity, which differs between species, populations, individuals, even traits, is considered as one of the mechanisms of plant invasion. We conducted a common garden experiment with six provenances (HRB, CC, HG, ML, MZ, LB) of <em>Ambrosia artemisiifolia</em> and three nitrogen addition treatments to test their performance response. In order to explore the adaptation strategies of <em>A. artemisiifolia </em>towards heterogeneous habitats, phenotypic plasticity indexes were calculated to analyze among different provenances and traits. All traits were significantly influenced (<em>P</em><0.05) by provenance, except for number of inflorescences, inflorescences length and intercellular CO<sub>2</sub> concentration. Nitrogen addition notably affected on seed length, root biomass ratio, root-shoot ratio and four physiological traits (Pn, Tr, Gs, Ci). Among six provenances, the phenotypic plasticity index differed significantly (<em>P</em><0.05), but there were no significant differences of plasticity among nitrogen treatments. And biomass phenotypic plasticity was relatively higher both in response to prevenance and to nitrogen. We also found that only the plasticity of 100-seed weight was closely related to latitude, climate and genetic factors. In summary, provenances had a greater impact on the phenotype and plasticity of <em>A. artemisiifolia</em> than nitrogen addition, indicating the potential for further evolution of plasticity. Differences in plasticity among provenances and traits are important in predicting the invasion trend of <em>A. artemisiifolia</em> in the future.</span></p>
