Microspore Culture in eleven Cultivars of Loquat
In plant breeding, microspore embryogenesis via isolated microspore culture is increasing as a method to obtain in a single-step doubled haploids and homozygosity. In this study, isolated microspore culture of eleven cultivars of loquat (Eriobotrya japonica (Thunb.) Lindl.) has been carried out. An analysis of anthers from different flower bud sizes, has been carried out, to identify and to select the flower bud size with anthers containing the highest quantity of vacuolated microspores. After a pre-treatment of the panicles at 4°C in dark for 4 days, flower buds were sterilized and microspores were isolated and cultured in two different media (P and MB). Moreover, only the isolated microsp…
Interim 2017/18 influenza seasonal vaccine effectiveness: combined results from five European studies
Between September 2017 and February 2018, influenza A(H1N1)pdm09, A(H3N2) and B viruses (mainly B/Yamagata, not included in 2017/18 trivalent vaccines) co-circulated in Europe. Interim results from five European studies indicate that, in all age groups, 2017/18 influenza vaccine effectiveness was 25 to 52% against any influenza, 55 to 68% against influenza A(H1N1)pdm09, -42 to 7% against influenza A(H3N2) and 36 to 54% against influenza B. 2017/18 influenza vaccine should be promoted where influenza still circulates. Funding: The five studies have received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 634446 to conduct the study in…
