International Union for the Protection of New Varieties of Plants
We developed 22 SSRs by using 3 approaches, RAHM (random amplified hybridization microsatellites), 5’ anchored PCR methods and an enriched genomic library. Seventy of 22 SSRs could be successfully amplified for Pyrus spp., which showed highly polymorphic. Sixty Asian pear accessions from 6 Pyrus species were genetically identified by 9 SSR markers with a total of 133 putative alleles. The SSR m...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Introducing Hurwitz Numbers for Severi-type Varieties
Fixing an arbitrary point p ∈ CP and a triple (g, d, `) of nonnegative integers satisfying the inequality g ≤ (d+l−1 2 ) − (l 2 ) , we associate a natural Hurwitz number to the (open) Severi-type varietyWg,d,` consisting of all reduced irreducibke plane curves of degree d + l with genus g and having an ordinary singularity of order l at p (the remaining singular points of such curves being usua...
متن کاملIntroducing aromatic amino acid hydroxylases from plants.
In humans, a deficiency in Phe hydroxylase activity results in phenylketonuria, a metabolic disorder that is characterized by the accumulation of Phe. Phe hydroxylase belongs to the iron-containing aromatic amino acid hydroxylase (AAH) family, whose members catalyze the hydroxylation of Phe, Trp, or Tyr in a reaction that depends on the donation of electrons by tetrahydropterin (reviewed in Fit...
متن کاملIntroducing new technology safely.
AIM This report considers the introduction of new technology and the implications for patient safety. METHODS AND DISCUSSION A distinction is made between 'conceptually' new and 'contextually' new technology. The life cycle of technology from development to routine use is discussed and the key role for regulation, health technology assessment, clinical engineering and surveillance in this lif...
