Phylogenetic position of the Chromista plastids based on small subunit rRNA coding regions

open access: closedCurrent Genetics, 1995
The kingdom Chromista contains eukaryotic organisms with tubular mastigonemes on the leading flagellum of their bi-flagellated stages, and plastids within a chloroplast endoplasmic reticulum (CER). The complex series of events leading to the formation of the CER is hypothesized to have occurred only once.

Evolutionary analysis revealed the horizontal transfer of the Cyt b gene from Fungi to Chromista.

Molecular Phylogenetics and Evolution, 2014
In this study, the cytochrome b (Cyt b) amino acid sequences were analyzed in 50 organisms covering all 5 kingdoms of eukaryotes. Six conserved domains, i.e., heme bL binding sites, heme bH binding sites, Qo binding sites, Qi binding sites, the interchain domain interface, and the intrachain domain interface were found in all investigated sequences ...

ENDOMEMBRANE STRUCTURE AND THE CHLOROPLAST PROTEIN TARGETING PATHWAY IN HETEROSIGMA AKASHIWO (RAPHIDOPHYCEAE, CHROMISTA)

open access: closedJournal of Phycology, 2000
Chloroplasts in heterokont algae are surrounded by four membranes and probably originated from a red algal endosymbiont that was engulfed and retained by eukaryotic host. Understanding how nuclear‐encoded chloroplast proteins are translocated from the cytoplasm into the chloroplast across these membranes could give us some insights about how the ...

L'ultrastructure du sporange de Pseudoperonospora humuli (chromista, oomycota, peronosporales)

open access: closedCryptogamie Mycologie, 2000
Abstract The ultrastructure of the sporangium, particularly the dehiscence apparatus in Pseudoperonospora humuli is similar to the one described in P. cubensis. This similarity is considered an indication of the homogeneity of the genus Pseudoperonospora. The dehiscence apparatus in P.
