A PCR-based ‘molecular tool box’, based on a region of the ras-related protein gene Ypt 1, was developed for the identification of 15 Phytophthora species that damage forests and trees: P. cactorum , P. cambivora , P. cinnamomi , P. citricola , P. europaea , P. inundata , P. lateralis , P. megasperma , P. nemorosa , P. kernoviae , P. pseudosyringae , P. psychrophila , P. quercina , P. ramorum a...

Bioassay-guided fractionation of a CH(2)Cl(2)-MeOH extract of the aerial parts of Albizia inundata resulted in the isolation of two new natural oleanane-type triterpene saponins {3-O-[α-L-arabinopyranosyl(1→6)]-2-acetamido-2-deoxy-β-D-glucopyranosyl oleanolic acid (1) and 3-O-[α-L-arabinopyranosyl(1→2)-α-L-arabinopyranosyl(1→6)]-2-acetamido-2-deoxy-β-D-glucopyranosyl acacic acid lactone (2)} al...

Given the lack of a resistant genetic pool in host plants, the introduction of exotic invasive pathogens can result in epidemics that affect a specific ecosystem and economy. Plant quarantine, which is designed to protect endemic plant resources, is a highly invaluable safeguard that should keep biosecurity with increasing international trade and global transportation. A total of 34 species of ...

Abstract Non-vascular plants associating with arbuscular mycorrhizal (AMF) and Mucoromycotina ‘fine root endophyte’ (MFRE) fungi derive greater benefits from their fungal associates under higher atmospheric [CO 2 ] (a[CO ]) than ambient; however, nothing is known about how changes in a[CO affect MFRE function vascular plants. We measured movement of phosphorus (P), nitrogen (N) carbon (C) betwe...
