Both the origin of domesticated apple and the overall phylogeny of the genus Malus are still not completely resolved. Having this as a target, we built a 134,553-position-long alignment including two previously published chloroplast DNAs (cpDNAs) and 45 de novo sequenced, fully colinear chloroplast genomes from cultivated apple varieties and wild apple species. The data produced are free from c...

The types of plant diversity on the territory Radomyshl Forestry in areas with different forest vegetation conditions were investigated. 21 species belonging to 15 families and 18 genera have been identified. main are determined (Pinus sylvestris-Vaccinium vitisidaea+V. myrtillus-Cladonia spp.+ Pleurozium; Pinus sylvestris-Calluna vulgaris-Pleurozium+ Cladonia ssp.; myrtillus-Pleurozium; sylves...

The batch sorption capability of Romanian pine bark for the removal of Cu(II) and Zn(II) ions from diluted aqueous solutions was investigated as a function of initial pH, contact time, and temperature. The metal sorption sequence is Cu > Zn. The experimental data for Cu(II) and Zn(II) ions retention on the tested bark of Pinus sylvestris L. showed a better compliance with the pseudo–second orde...

Our findings suggest that i) phytotoxic materials can be isolated from Bursaphelenchus xylophilus-infected Scots pine, but not from noninfected pines; ii) the phytotoxins cause wilting of 45-day-old and 2-year-old pine seedlings in a dose and species dependent manner; iii) the phytotoxins are produced early in the infection, accumulate or increase with time, and may function to suppress water t...

Plant alkaloids, one of the largest groups of natural products, provide many pharmacologically active compounds. Several genes in the biosynthetic pathways for scopolamine, nicotine, and berberine have been cloned, making the metabolic engineering of these alkaloids possible. Expression of two branching-point enzymes was engineered: putrescine N-methyltransferase (PMT) in transgenic plants of A...

The side effects and the emerging resistance to the available drugs against leishmaniasis and trypanosomiasis led to the urgent need for new therapeutic agents against these diseases. Thirty one extracts of thirteen medicinal plants from the Brazilian Cerrado were therefore evaluated in vitro for their antiprotozoal activity against promastigotes of Leishmania donovani, and amastigotes of Trypa...

UNLABELLED PREMISE OF THE STUDY A set of novel expressed sequence tag (EST) microsatellite markers was developed in Pinus sylvestris var. mongolica to promote further genetic studies in this species. • METHODS AND RESULTS One hundred seventy-five EST-simple sequence repeat (SSR) primers were designed and synthesized for 31,653 isotigs based on P. tabuliformis EST sequences. The primer pair...
