We performed next-generation sequencing of the 18S rDNA–ITS1–5.8S rDNA region along with traditional Sanger rbcL, matK, ndhF, and ITS1–5.8S rDNA–ITS2 to clarify hybridization pattern in subtribe Alopecurinae genus Alopecurus particular. Our data support hybrid origin × brachystylus from between A. geniculatus (sect. Alopecurium) pratensis Alopecurus). Moreover, brachystylus, only aequalis-like ribotypes tetraploid participated. Surprisingly, we found traces introgression arundinaceus-like...

Radial increment objectively reflects the quality of assimilation apparatus a woody plant. Its features indicate influence various anthropogenic, biotic and abiotic factors as well stability plant under stress. The aim this study was to survey long-term dynamics radial growth six tree species: Betula pendula, Ulmus glabra, Quercus robur, Tilia cordata, Picea abies Pinus silvestris, depending on impact creating reservoir fluctuations water level in it. Additionally, another determine whether...

The member of trace-amine associated receptor family, TAAR5 was suggested to recognize tertiary amines, mostly in the olfactory system; however, knocking out mice showed an enhancing effect on adult neurogenesis and dopamine neurotransmission striatum. To estimate role TAAR5, we performed gene expression profiling striatal samples from knockout (KO) their wild-type littermates. higher several genes involved dopaminergic signaling downregulation with gliogenesis were revealed TAAR5-KO mice....
