Rhizosphere Iron (III) Deposition and Reduction in a Juncus effusus L.-Dominated Wetland

soil and rates of radial oxygen loss. Radial O2 loss is in turn influenced by plant activity (Bedford et al., 1991; Iron (III) plaque forms on the roots of wetland plants from the Kuehn and Suberkropp, 1998) and morphological charreaction of Fe(II) with O2 released by roots. Recent laboratory studies acteristics such as suberized and lignified roots (Armhave shown that Fe plaque is more rapidly...

Growth inhibition as indicator of stress because of atrazine following multiple toxicant exposure of the freshwater macrophyte, Juncus effusus L.

Atrazine is a herbicide used most frequently in North America, but it usually is encountered in mixtures of agrochemicals. Few atrazine exposure studies have been conducted using mixed pesticides; therefore, little data are available to suggest reliable means of discerning effects attributable to atrazine. The common freshwater macrophyte, Juncus effusus L., was exposed in 66 mesocosms to atraz...

Establishment of Agrobacterium-mediated Bt Gene Transformation System in Mat Rush (juncus Effusus L.)

Agrobacterium-mediated genetic transformation was explored for inducing insect resistance in mat rush (Juncus effusus L.). Firstly, the callus regeneration system was established, and secondly the Agrobacterium tumefaciens strain EHA105 with plasmid pKUB carrying cryIA(b), hph and gus genes, coding for hygromycin phosphotransferase and β-glucuronidase, respectively, was used for transformation....
