Lygodium japonicum fern accumulates copper in the cell wall pectin.
The present work reports the results of a study on the growth kinetics and characterization of matrix polysaccharides in the cell walls of Lygodium japonicum prothallium grown in the presence of copper (Cu). When the prothallium was cultured in the media containing 0.2 mM or 0.4 mM CuSO(4), it showed a rapid accumulation of Cu with a maximum uptake of Cu measured in the cells up to 20 d of cult...
متن کاملJapanese Climbing Fern (Lygodium japonicum) Management in Florida’s Apalachicola Bottomland Hardwood Forests
Japanese climbing fern (Lygodium japonicum) is an invasive vine that has been identified as an economic and ecological threat in forest ecosystems of the Southeast. In two separate studies, we examined the use of directed sprays of glyphosate, imazapyr, and metsulfuron-methyl herbicides, alone and in combination, for control of Japanese climbing fern and for impacts to associated vegetation in ...
متن کاملPlastome Sequences of Lygodium japonicum and Marsilea crenata Reveal the Genome Organization Transformation from Basal Ferns to Core Leptosporangiates
Previous studies have shown that core leptosporangiates, the most species-rich group of extant ferns (monilophytes), have a distinct plastid genome (plastome) organization pattern from basal fern lineages. However, the details of genome structure transformation from ancestral ferns to core leptosporangiates remain unclear because of limited plastome data available. Here, we have determined the ...
متن کاملEvidence for a gibberellin biosynthetic origin of ceratopteris antheridiogen.
The species-specific chemical messenger, antheridiogen A(Ce), mediates the differentiation of male gametophytes in the fern Ceratopteris. In order to investigate the biochemical origin of antheridiogen, the effect of the inhibitors, 2'-isopropyl-4'-(trimethylammoniumchloride)-5' -methylphenylpiperidine-1-carboxylate (AMO-1618), 2-chloroethyl trimethylammonium chloride (CCC), and alpha-cycloprop...
