Histones were extracted from chromatin of the following: a moss (Polytrichum juniperinum); the primitive vascular plants Psilotum nudum and Equisetum arvense; a fern (Polypodium vulgare); the gymnosperms fir (Abies concolor), yew (Taxus canadensis) and Gingko biloba; the dicotyledonous angiosperms

Chitinase-A from a lycophyte Selaginella doederleinii (SdChiA), having molecular mass of 53 kDa, was purified to homogeneity by column chromatography. The cDNA encoding SdChiA was cloned by rapid amplification of cDNA ends and polymerase chain reaction. It consisted of 1477 nucleotides and its open

The phytotoxicity of formaldehyde for spider plants (Chlorophytum comosum L.), tobacco plants (Nicotiana tabacum L. cv Bel B and Bel W3), and soybean (Glycine max L.) cell-suspension cultures was found to be low enough to allow metabolic studies. Spider plant shoots were exposed to 7.1 [mu]L L-1

Silicon (Si) is a beneficial element to plants, and its absorption via transporters leads to protective effects against biotic and abiotic stresses. In higher plants, two groups of root transporters for Si have been identified: influx transporters (Lsi1) and efflux transporters (Lsi2). Lsi1
