Nuclear dynamics, mitosis, and the cytoskeleton during the early stages of colony initiation in Neurospora crassa.
Neurospora crassa macroconidia form germ tubes that are involved in colony establishment and conidial anastomosis tubes (CATs) that fuse to form interconnected networks of conidial germlings. Nuclear and cytoskeletal behaviors were analyzed in macroconidia, germ tubes, and CATs in strains that expressed fluorescently labeled proteins. Heterokaryons formed by CAT fusion provided a rapid method f...
متن کاملCell Fusion in Neurospora crassa
The primary research aims of this thesis were the identification of novel cell fusion mutants of Neurospora crassa and the subsequent functional characterization of selected candidate proteins during conidial anastomosis tube (CAT)-mediated cell fusion by means of genetic, molecular, biochemical and live-cell imaging analysis. Chapter 1 provides a general introduction of the model organism and ...
متن کاملLive-cell imaging of conidial fusion in the bean pathogen, Colletotrichum lindemuthianum.
Fusion of conidia and conidial germlings by means of conidial anastomosis tubes (CATs) is a common phenomenon in filamentous fungi, including many plant pathogens. It has a number of different roles, and has been speculated to facilitate parasexual recombination and horizontal gene transfer between species. The bean pathogen Colletotrichum lindemuthianum naturally undergoes CAT fusion on the ho...
متن کاملConidial anastomosis tubes in filamentous fungi.
Conidial anastomosis tubes (CATs) can be recognized in 73 species of filamentous fungi covering 21 genera, and develop in culture and in host-pathogen systems. They have been shown to be morphologically and physiologically distinct from germ tubes in Colletotrichum and Neurospora, and under separate genetic control in Neurospora. CATs are short, thin, usually unbranched and arise from conidia o...
متن کاملEarly colony establishment in Neurospora crassa requires a MAP kinase regulatory network.
Vegetative fusion is essential for the development of an interconnected colony in many filamentous fungi. In the ascomycete fungus Neurospora crassa, vegetative fusion occurs between germinated conidia (germlings) via specialized structures termed "conidial anastomosis tubes" (CATs) and between hyphae within a mature colony. In N. crassa, both CAT and hyphal fusion are under the regulation of a...
