Abstract Background Lipid-specific live cell dyes are an important tool for the study of algal lipid metabolism, the monitoring of lipid production, and the identification of algal strains with high lipid yields. Nile Red and BODIPY have emerged as t

Land plants are anchored in one place for most of their life cycle and therefore must constantly adapt their growth and metabolism to abiotic stresses such as light intensity, temperature and the availability of water and essential minerals. Thus, pl

Chloroplasts are the powerhouse of the plant cell, yet they are resource-intensive and will cause photooxidative damage if their activity overshoots the demands of growth. The adjustment of chloroplast activity to match growth is therefore vital for

Guanosine tetraphosphate (ppGpp) accumulation inhibits chloroplast gene expression and promotes super grana formation in the moss Physcomitrium (Physcomitrella) patens

SummaryThe nucleotides guanosine tetraphosphate and pentaphosphate (or ppGpp) are implicated in the regulation of chloroplast function in plants. ppGpp signalling is best understood in the model vascular plant Arabidopsis thaliana where it acts to re

SummaryChloroplasts retain elements of a bacterial stress response pathway that is mediated by the signalling nucleotides guanosine penta- and tetraphosphate, or (p)ppGpp. In the model flowering plant Arabidopsis, ppGpp acts as a potent regulator of
