Membrane proteins Bqt3 and -4 anchor telomeres to the nuclear envelope to ensure chromosomal bouquet formation
A screen identifies two more bouquet proteins required for meiotic telomere clustering: Bqt4 anchors the telomeres, whereas Bqt3 protects Bqt4 from degradation.
Fission yeast autophagy induced by nitrogen starvation generates a nitrogen source that drives adaptation processes
It is proposed that fission yeast autophagy functions to supply nitrogen and is activated when cells cannot access exogenous nitrogen, thus ensuring that they can adapt and subsequently propagate.
Fission yeast Ags1 confers the essential septum strength needed for safe gradual cell abscission
The α(1-3)glucan synthase Ags1 is essential for both secondary septum formation and the primary septum structural strength needed to counter cell turgor pressure during cell separation.
Cooperation between Paxillin-like Protein Pxl1 and Glucan Synthase Bgs1 Is Essential for Actomyosin Ring Stability and Septum Formation in Fission Yeast
It is indicated that CAR anchorage to the plasma membrane through Cdc15 and Pxl1, and concomitant Bgs1 activity, are necessary for CAR maintenance and septum formation in fission yeast.
A New Membrane Protein Sbg1 Links the Contractile Ring Apparatus and Septum Synthesis Machinery in Fission Yeast
This study establishes Sbg1p as a key member of a group of proteins that link the plasma membrane, the actomyosin ring, and the division septum assembly machinery in fission yeast.
Size-dependent toxicity of silica nano-particles to Chlorella kessleri
SiO2 nano-particles were found to exhibit size-dependent toxicity toward the alga, Chlorella kessleri, and are toxic, at least for algae in aquatic media.
Breakage of the nuclear envelope by an extending mitotic nucleus occurs during anaphase in Schizosaccharomyces japonicus
A form of mitosis in which the nuclear envelope is torn by elongation of the nucleus in the fission yeast Schizosaccharomyces japonicus is described, providing insight into the diversity ofMitosis and the biological significance of breakdown of thenuclear envelope.
In situ localization of cell wall α‐1,3‐glucan in the fission yeast Schizosaccharomyces pombe
Transmission electron microscope images showed that most of the alpha-1,3-glucan was along the cell membrane and appeared to enclose the cytoplasm, supporting previous reports that this glucan is synthesized on the cell membranes.
