Photosynthesis in Eurasian Watermilfoil (Myriophyllum spicatum L.).
Gas exchange of Eurasian watermilfoil (Myriophyllum spicatum L.) indicated a near-zero CO(2) compensation point and a high temperature optimum for photosynthesis. These properties are characteristic of plants fixing CO(2) by a beta-carboxylation mechanism. Operation of the Calvin cycle was shown and no evidence for beta-carboxylation was obtained. These results indicate that near-zero CO(2) com...
متن کاملDevelopment of microsatellite markers in the hexaploid aquatic macrophyte, Myriophyllum spicatum (Haloragaceae)1
UNLABELLED PREMISE OF THE STUDY We developed microsatellite primers to investigate genetic diversity and population genetic structure of the cosmopolitan submerged plant Myriophyllum spicatum. • METHODS AND RESULTS Twenty microsatellite loci were identified in M. spicatum using the microsatellite-enriched library method. The numbers of alleles per locus ranged from one to 13, and the expec...
متن کاملInfluence of geography and environment on patterns of genetic differentiation in a widespread submerged macrophyte, Eurasian watermilfoil (Myriophyllum spicatum L., Haloragaceae)
The effects of geographic and environmental variables on the pattern of genetic differentiation have been thoroughly studied, whereas empirical studies on aquatic plants are rare. We examined the spatial genetic differentiation of 58 Myriophyllum spicatum populations distributed throughout China with 12 microsatellite loci, and we analyzed its association with geographic distance, geographic ba...
متن کاملCopper Accumulation, Tolerance and Release by a Submerged Aquatic Plant Myriophyllum Spicatum L
EXTENDED ABSTRACT Myriophyllum spicatum L. is a common macrophyte in aquatic environments and is often considered as preferred aquatic plants in phytoremediation. We investigated Cu accumulation, tolerance and release of the submerged aquatic plant M. spicatum and its potential for Cu phytoremediation. Plant shoots accumulated Cu with a maximum of 18 735 mg Cu kg dry weight after exposed to 62....
متن کاملSeasonal and spatial dynamics of allelochemicals in the submersed macrophyte Myriophyllum spicatum L
Myriophyllum spicatum L. (or milfoil for short) is a highly competitive submersed macrophyte which can replace other submersed macrophytes and form monospecific stands. Frequently, epiphyte cover and phytoplankton development is low in M. spicatum dominated systems. Milfoil shoots grow fast and tall and tend to form canopies at the water surface depriving underlying photosynthetic organisms of ...
