Typifications and synonymy in Polystichum (Dryopteridaceae) from Chile and Argentina
Polystichum Roth is one of the largest and most taxonomically challenging fern genera. South American species have a rich and complex nomenclatural history; many of the early names are inadequately typified. Based on extensive examination of original type material, we designate eleven lectotypes (including Aspidium mohrioides, Aspidium montevidense f. imbricata, Aspidium montevidense f. squamul...
متن کاملOrigin of Hawaiian Polystichum (Dryopteridaceae) in the context of a world phylogeny.
A genus-wide molecular phylogeny for Polystichum and allied genera (Dryopteridaceae) was reconstructed to address the biogeographic origin and evolution of the three Hawaiian Polystichum species, all endemic there. The analysis was based on the cpDNA sequences rbcL and the trnL-F spacer from a taxonomically and geographically diverse sample. Parsimony and Bayesian phylogenetic analyses of the c...
متن کاملCytological Features of the Egg Cell Protoplasts Isolated from Gametophytes of Fern, Struthiopteris niponica (Kunze) Nakai
Egg cell protoplasts were isolated from the gametophyte of the fern, Struthiopteris niponica (Kunze) Nakai. Archegonia were excised from the prothallia and then digested in an enzyme solution that contained Cellulase "Onozuka" RS and Macerozyme R-10. After 3 hours of incubation, the egg cell protoplasts had separated completely from the somatic cells. The protoplasts had such cytological featur...
متن کاملBioactive furanoeremophilanes from Senecio otites Kunze ex DC.
The furanoeremophilanes 6 beta-angeloyloxy-1,10-dehydrofuranoeremophilan-9-one (1), 6 beta-hydroxy-1,10-dehydrofuranoeremophilan-9-one (2) and 6 beta-propionyloxy-1,10-dehydrofuranoeremophilan-9-one (3) were isolated from Senecio otites, their structures elucidated by spectral analyses, and their insecticidal and phytotoxic properties evaluated. Compounds 1-3 proved to be effective aphid antife...
متن کاملPhylogenetic Relationships of the Fern Cyrtomium falcatum (Dryopteridaceae) from Dokdo Island Based on Chloroplast Genome Sequencing
Cyrtomium falcatum is a popular ornamental fern cultivated worldwide. Native to the Korean Peninsula, Japan, and Dokdo Island in the Sea of Japan, it is the only fern present on Dokdo Island. We isolated and characterized the chloroplast (cp) genome of C. falcatum, and compared it with those of closely related species. The genes trnV-GAC and trnV-GAU were found to be present within the cp genom...
