Ceratiomyxa - Wikipedia
Ceratiomyxa is a genus of plasmodial slime mould within the Eumycetozoa, first described by Pier Antonio Micheli. They are widely distributed and commonly found on decaying wood. The plasmodium often appears as white frost-like growth or thin watery layers on wood.
The life cycle of Ceratiomyxa differs at several points from the usual cycle for the Myxogastromycetidae. One major point of interest is at the germination of the spore. Soon after it emerges from the spore case, the protoplast is divided into 8 portions, which for a time remain close together as an "octette''. Then each
Molecular phylogenetic analyses support the validity of Ceratiomyxa …
2024年6月1日 · The SSU rRNA single gene phylogenetic tree, consisting of eumycetozoan taxa with Dictyostelia as an outgroup, shows our Ceratiomyxa spp. isolates forming a monophyletic group with other publicly available Ceratiomyxa spp. sequences within Protosporangiida with full support from both maximum likelihood and Bayesian analyses.

2022年1月1日 · At least four species of Ceratiomyxa are recognized today, but all detailed studies of the life cycle have been based on C. fruticulosa. Although not regarded as a true myxomycete in the strictest sense, Ceratiomyxa is normally included in monographs and inventories of myxomycetes as a separate subclass Ceratiomyxomycetidae.

2018年2月7日 · The protoplast which emerges from the spore of Ceratiomyxa fruticulosa produces eight swarm cells. The published accounts of the life cycle differ in their descriptions of the steps between germination of the spore and formation of the swarm cells.
Studies in our laboratory on numerous collections of Ceratiomyxa, mostly classifiable as C. fruticulosa, and comparisons of these collections with typical protostelids lend additional support to our earlier decision to transfer the genus from subclass Myxogastria to subclass Protostelia of the Eumycetozoa.

2017年8月1日 · Myxomycetes (also known as plasmodial slime molds or myxogastrids) are a group of free-living terrestrial heterotrophs with complex life cycles. The unicellular forms are amoebae and flagellates (collectively, the “amoeboflagellate” stage). These develop, usually via sexual fusion, into a multinucleate “plasmodium” stage, which is also trophic.
Several detailed life-history studies of Ceratiomyxa have been made by Famintzin and Woronin in 1873, Olive in 1907, Jahn in 1908, and Gilbert in 1935. Although admittedly somewhat repetitious, a brief discussion of the life cycle of Ceratiomyxa with emphasis on its dif-ference from other Myxomycetes would seem helpful in interpreting
Myxomycetes (also known as plasmodial slime molds or myxogastrids) are a group of free-living terrestrial heterotrophs with complex life cycles. The unicellular forms are amoebae and agellates (collectively, the “amoebo agellate stage). These develop, usually. via sexual fusion, into a multinucleate“plasmodium stage, which is also trophic.

2007年11月23日 · The myxomycete life cycle (Fig. 1) encompasses two very different trophic stages, one consisting of uninucleate amoebae, with or without flagella, and the other consisting of a distinctive multinucleate structure, the plasmodium (Martin et al. 1983). Under favorable conditions, the plasmodium gives rise to one or more fruiting bodies containing ...
