Early transcription in Caenorhabditis elegans embryos
... The time of onset for embryonic transcription in C. elegans has previously been assessed indirectly by two different methods, with somewhat differing results. In situ hybridization with labelled oligo(dT) probes to detect poly(A)+ mRNAs showed the first detectable increase in nuclear labelling at ap ...

F-Actin-Dependent Endocytosis of Cell Wall

In plants, formation of large intracellular compartments in response to BFA treatment is a unique feature of some, but not all, cells. Here, we have analyz ...
