Complete mitogenomes of the chlorophyte green algae Scherffelia dubia and Tetraselmis sp. CCMP 881 (Chlorodendrophyceae)

Mitochondrial DNA. Part B. Resources, 2020
We report here the first mitogenome sequences for the chlorophyte class Chlorodendrophyceae. The mitogenomes of Tetraselmis sp. CCMP 881 and Scherffelia dubia (SAG 17.86) are 46,904 bp and 78,958 bp long, respectively, but their gene repertoires are ...

How and why DNA barcodes underestimate the diversity of microbial eukaryotes [PDF]

, 2011
Background: Because many picoplanktonic eukaryotic species cannot currently be maintained in culture, direct sequencing of PCR-amplified 18S ribosomal gene DNA fragments from filtered sea-water has been successfully used to investigate the astounding ...

A gene-rich and compact chloroplast genome of the green alga Nephroselmis pyriformis (N.Carter) Ettl 1982 from the shores of Mersin (Eastern Mediterranean Sea)

Mitochondrial DNA. Part B. Resources, 2021
We report the complete chloroplast genome of the MED1 strain of Nephroselmis pyriformis from the Eastern Mediterranean Sea. At 111,026 bp, this genome is smaller and more compact than those of Nephroselmis olivacea and Nephroselmis astigmatica, and in ...

How endo- is endo-?: surface sterilization of delicate samples: a Bryopsis (Bryopsidales, Chlorophyta) case study [PDF]

, 2010
In the search for endosymbiotic bacteria, elimination of ectosymbionts is a key point of attention. Commonly, the surface of the host itself or the symbiotic structures are sterilized with aggressive substances such as chlorine or mercury derivatives ...

Complete mitogenomes of the marine picoplanktonic green algae Prasinoderma sp. MBIC 10622 and Prasinococcus capsulatus CCMP 1194 (Palmophyllophyceae)

Mitochondrial DNA. Part B. Resources, 2020
Marine picoalgae from the Prasinococcales order occupy the deepest branch of the Chlorophyta (Palmophyllophyceae). Here, we describe the mitogenomes of Prasinoderma sp. MBIC 10622 and Prasinococcus capsulatus CCMP 1194.

Cold Stress Response: An Overview in Chlamydomonas

Frontiers in Plant Science, 2020
Low temperature (or cold) is one of the major environmental factors that limit the growth and development of many plants. Various plant species have evolved complex mechanisms to adjust to decreased temperature.

The Mechanisms of Codon Reassignments in Mitochondrial Genetic Codes [PDF]

, 2007
Many cases of non-standard genetic codes are known in mitochondrial genomes. We carry out analysis of phylogeny and codon usage of organisms for which the complete mitochondrial genome is available, and we determine the most likely mechanism for codon ...
