Solanum dulcamara occurs in a broad range of ecologically contrasting habitats, ranging from permanent wetlands to dry costal dunes (Dawood et al. ; Visser et al. ). In autumn and , seeds of S. dulcamara were collected at nine locations along the coast of the Netherlands (Fig. 1). At each location, habitats with contrasting. Given that photosynthetic light responses are highly plastic in response to conditioning light levels (Björkman, ) and that different species/lineages of Hawaiian lobeliads occur in substantially different light environments, using a phylogenetically structured analysis on field data would conflate the effects of phylogeny and ecology.

Assembled plastomes were aligned to the completely annotated bittersweet (Solanum dulcamara L.) plastome available from GenBank (NC; Amiryousefi et al., ). Annotations were transferred from the references to the assembled plastomes using Geneious v with a similarity threshold of 80%, and were then checked and refined manually. We used Solanum dulcamara L. (Solanaceae) plants originating from different populations in the vicinity of Berlin (Erkner: 52° 25′ ″ N; 13° 46′ ″ E, Grunewald: 52° 27′ ″ N; 13° 11′ ″ E, and Siethen 52° 16′ ″ N; 13° 11′ ″ E) and from the Netherlands (Friesland: 52° 58′ ” N 5°

Plant material. In , seeds of Solanum dulcamara were collected at the North Sea island Texel (53° 7′24″N, 4° 47′10″E) and at the more southern coastal location Voorne (51° 51′2″N, 4° 4′29″E). For each of these locations, seeds were sampled in a wetland population at the shores of freshwater dune lakes, and in a dryland population at dry primary sand dunes well above the. Accepted by.

Summary. Clonal replicates of six genotypes of Solanum dulcamara L. grown in eight different environments were compared for photosynthesis and growth. Four of the genotypes were native to shaded habitats, two to sun habitats.

The experimental growth environments differed in light level, daily temperature amplitude and substrate moisture availability. Photosynthetic and growth properties of Solanum dulcamara L. were studied under controlled environments. The experimentally tested plants were clonal replicates of five field-collected individuals, three from fully exposed habitats and two from deeply shaded habitats.

After 4 weeks of growth in one of eight environmental treatments, each plant was measured for leaf adaxial Cited by: Photosynthetic and growth properties of Solanum dulcamara L.

Solanum dulcamara is one of the species found in an unu-sually wide range of light habitats (9, 12) and has been suggested to have two physiological races, one adapted to low and one adapted to high light conditions (12).

The high-energy cost and apparently low plasticity of C4 photosynthesis, compared to C3 photosynthesis, may limit the productivity and distribution of C4 plants in low light (LL) environments.

As noted earlier, Solanum dulcamara is widely distributed across a spectrum of habitats, from perpetually flooded to typically “ mesophytic ” to chronically droughted. In general, contrasting habitats can be expected to lead to local adaptation, i.e. directional selection producing genotypes particularly fit to their habitat.
