In the course of the 4th German National Forest Inventory, samples of the two oak species Quercus robur and Quercus petraea were collected throughout Germany. Genetic analyses were performed based on 403 nuclear, 21 chloroplast and 7 mitochondrial markers. The analyses showed good differentiation between the two species based on genetic data. Both species are connected through hybridization and introgression, but only about 2%...

Mosquitoes are significant vectors of various pathogens. Unlike vertebrates, insects rely solely on innate immunity. Hemocytes play a crucial role in the cellular part of the innate immune system. The gaseous radical nitric oxide (NO) produced by hemocytes acts against pathogens and also functions as a versatile transmitter in both the immune and nervous systems, utilizing cyclic guanosine monophosphate (cGMP) as a second mess...

SARS-CoV-2 has emerged as a previously unknown zoonotic coronavirus that spread worldwide causing a serious pandemic. While reliable nucleic acid–based diagnostic assays were rapidly available, only a limited number of validated serological assays were available in the early phase of the pandemic. Here, we evaluated a novel flow cytometric approach to assess spike-specific antibody responses.HEK 293T cells expressing SARS-CoV-...
