Abstract:
... Enrichment of specific RNAs is important for RNA analysis. MnCl2 has been used previously to enrich viroid RNA fractions from total RNA from infected plants. We have expanded this method to show that MnCl2 can enrich single-stranded as well as structured RNAs of 450 nt and below from a total RNA preparation. We have applied this method to map the transcription start sites of a PSTVd transcript fro ...

We demonstrate that the method performs well on as little as 4 mg of cells scraped directly from a few colonies. Sensitivity, specificity and reproducibility of the scaled‐down method are comparable with those ...

Abstract:
... Microautophagy is originally defined as lysosomal (vacuolar) membrane dynamics to directly enwrap and transport cytosolic components into the lumen of the lytic organelle. Molecular details of microautophagy had remained unknown until genetic studies in yeast identified a set of proteins required for the process. Subsequent studies with other experimental model organisms resulted in a series of di ...
