Title:
Loss of nuclear flavanols during drought periods in Taxus baccata 
Abstract:
Normally, needles of Taxus baccata during the growth period prominently stain blue for nuclear flavanols with the histochemical DMACA procedure. However, under excess heat and drought conditions, nuclear flavanols of current-year needles decline to zero. Nevertheless, greenish-yellow-coloured flavonols (quercetin derivatives) were still observed in nuclei. All of these yellow nuclei were in a silenced state and without mitosis. This link between drought and loss of nuclear flavanols was found in...    »
