Development of antheridial filaments of Chara vulgaris L. in isolated antheridia in vitro

open access: yesActa Societatis Botanicorum Poloniae, 2014
The study was undertaken to establish the conditions of culture in vitro of Chara vulgaris L. antheridium isolated from the mother plant and to ascertain the regularities in the development of the antheridial filaments under these conditions. The culture

Deep Transcriptome Sequencing of Two Green Algae, Chara vulgaris and Chlamydomonas reinhardtii, Provides No Evidence of Organellar RNA Editing [PDF]

open access: yesGenes, 2017
Nearly all land plants post‐transcriptionally modify specific nucleotides within RNAs, a process known as RNA editing. This adaptation allows the correction of deleterious mutations within the asexually reproducing and presumably non‐recombinant ...

Effect of hydroxyurea on mitotic activity 3H-thymidine and 3H-phenylalanine incorporation in the antheridial filament cells of Chara vulgaris

open access: yesActa Societatis Botanicorum Poloniae, 2015
Hydroxyurea inhibits mitotic activity in cells of the antheridial filaments of Chara vulgaris by blocking phase S and phase G2. Blocking of cells in phase G2 also occurs in the case of the root meristem cells of Helianthus annuus and Vicia faba var ...

Cytochemical and immunocytochemical studies of the localization of histones and protamine-type proteins in spermatids of Chara vulgaris and Chara tomentosa.

open access: yesFolia Histochemica et Cytobiologica, 2008
Spermiogenesis in Chara algae, which has been divided into 10 phases (sp I-X), is similar to spermiogenesis in animals. The most important process during spermiogenesis in animals is remodeling of chromatin leading to "sleeping genome", being the result ...

The role of indole-3-acetic acid and characterization of PIN transporters in complex streptophyte alga Chara braunii. [PDF]

open access: yesNew Phytol
Summary Auxin, indole‐3‐acetic acid (IAA), is a key phytohormone with diverse morphogenic roles in land plants, but its function and transport mechanisms in algae remain poorly understood. We therefore aimed to explore the role of IAA in a complex, streptophyte algae Chara braunii. Here, we described novel responses of C.

Mitochondrial mRNA oligocitydylation occurs in Chlorophyceae and Ulvales but not Bryopsidales or Trebouxiophyceae. [PDF]

open access: yesJ Phycol
Abstract Mitochondrial mRNAs in the green algal class Chlorophyceae have non‐template 3' oligo‐cytosine‐rich additions, also known as oligo(C), polycitydylation, or poly(C) “tails.” These oligonucleotide additions are believed to be unique to green algal mitochondria, as none have been observed in any other organism.
