Establishment and regulation of polar growth in Streptomyces
… in developmental biology is how cells establish polarity, and most strikingly how cells grow polarly. From neuronal dendrites and root hairs to bud emergence and elongation of yeast, broadly conserved pathways control cell polarity in eukaryotes. In contrast, virtually nothing is known about the …

PopZ and FtsZ coordinate polar growth termination and cell division in Agrobacterium tumefaciens
… utilizing lateral cell wall biogenesis, polar growth in bacteria is less well understood. Yet, polar growth has been observed across taxonomically diverse bacteria like Actinobacteria and the alphaproteobacterial clade Rhizobiales (Howell and Brown, 2016). Interestingly, polar-growing …

The relevance of adenylate levels and adenylate converting enzymes on metabolism and development of potato (Solanum tuberosum L.) tubers
… coding for extensins, which are associated with polar growth. The results are discussed in context of adaptive responses of plants to changes in the adenylate levels and the proposed role of apyrase in apoplastic purinergic signaling and ATP salvaging. In summary, this thesis provides insight …

The essentiality of DivIVAEf oligomerization for proper cell division in enterococcus faecalis and interaction with a novel cell division protein
… division machinery, complete septum closure, and polar growth and morphogenesis. Although well conserved across various Gram-positive species, DivIVA is believed to be relatively species specific. One similarity among DivIVA homologues is the ability to oligomerize through coiled-coil interaction …

Regulation and communication between the NRD kinase COT1, the MAK2 MAP kinase and the Striatin complex in Neurospora crassa
Die Etablierung und Aufrechterhaltung der Zellpolarität sind wichtige und grundlegende Prozesse in Eukaryoten, die koordiniert werden müssen mit Zellteilung, Differenzierung und Zellwachstum. In dem filamentösen Pilz Neurospora crassa ist die NDR Kinase COT1 an der Koordination der polaren …

Distinct roles of PI4P 5-kinase isoforms in polar tip growth of pollen tubes
… Überexpression von Typ A Enzymen unterband das polare Wachstum der Pollenschläuche und führte zu einem Anschwellen der Pollenschlauchspitze sowie zu Veränderungen des Zytoskeletts und der Zytoplasmaströmung. Typ B Isoenzyme dagegen führten zu einer massiven Verstärkung der apikalen Exozytose von …
