The species of Pimpinella, one the largest genera family Apiaceae, are traditionally cultivated for medicinal purposes. In this study, high-throughput double digest restriction-site associated DNA sequencing technology (ddRAD-seq) was used to identify single nucleotide polymorphisms (SNPs) in eight Pimpinella from Iran. After double-digestion with enzymes HpyCH4IV and HinfI, a total 334,702,966...

Genetic elements that cheat Mendelian segregation by biasing transmission in their favor gain a significant fitness benefit. Several examples of sex-ratio meiotic drive, where one sex chromosome biases its own transmission at the cost of the opposite sex chromosome, exist in animals and plants. While the distorting sex chromosome gains a significant advantage by biasing sex ratio, the autosomes...

We examined the associations between intestinal helminth infracommunity structure and infection parameters and the age, size, and year and region of collection of 130 female lesser scaup (Aythya affinis) during their 2014-2015 spring migrations through the upper Midwest, USA. We identified a total of 647,174 individual helminths from 40 taxa, including 20 trematodes, 14 cestodes, 4 nematodes an...

Phenotypic plasticity describes the phenotypic adjustment of the same genotype to different environmental conditions and is best described by a reaction norm. We focus on the effect of ocean acidification on inter- and intraspecific reaction norms of three globally important phytoplankton species (Emiliania huxleyi, Gephyrocapsa oceanica and Chaetoceros affinis). Despite significant differences...

In this paper the genus Pheidologeton Mayr, 1862 is synonymized under Carebara Westwood, 1840 and the Carebara polita group is established and revised. This species group currently includes six species from the Afrotropical region (C. madibai, C. nicotianae, C. perpusilla, C. polita, C. silvestrii, and C. villiersi) and two species from the Neotropical region (C. brevipilosa and C. urichi). The...

No Brasil, o consumo de chás a base plantas medicinais e fitoterápicas advém do conhecimento empírico da população acerca dos benefícios uso cada espécie. Dentre os mais comercializados no Brasil estão as duas espécies conhecidas erva doce, Pimpinella anisum Foeniculum vulgare, utilizadas não apenas pelo seu efeito ansiolítico, mas também pelos seus controle sintomas climatério.

The chemical composition of the essential oil of fruits of Pimpinella haussknechtii. was studied by GC-MS. After GC-MS analysis, one unknown component (56.7%) was observed, which was not characterized in the GC-MS library. The essential oil of P.haussknechtii was injected to HPLC using YMC-Pak-Sil column (250 × 20 mm) with gradient system of hexane (A), and hexane: ethyl acetate, 9:1 (B) to yie...
