The Spirogyra pratensis genome illuminates the evolution of developmental programs and spiral chloroplast biology

Elisa S. Goldbecker, Deepti Varshney, Anja Holzhausen, Tatyana Darienko et autres

Zygnematophytes emerged as the unexpected closest algal relatives of land plants despite their simple body plans, raising questions about the morphogenetic toolkit present in the last common ancestor of land plants and algae. Genomic analyses have revealed that zygnematophytes are cellular giants, …

Bryotherm - Thermomorphogenesis as a mechanism to adapt to elevated temperatures in early land plant evolution

Marcel Quint, Wenke Ludwig, Anja Holzhausen

The amplitude between the minimum and the maximum ambient temperature a plant has to endure during its life cycle is much larger in terrestrial than in aquatic environments. As such, especially elevated ambient temperatures are among the most prominent abiotic factors plants …

Conserved carotenoid pigmentation in reproductive organs of Charophyceae

Tim P. Rieseberg, Anja Holzhausen, Maaike J. Bierenbroodspot, W Zhang et autres

Sexual reproduction in Charophyceae abounds in complex traits. Their gametangia develop as intricate structures, with oogonia spirally surrounded by envelope cells and richly pigmented antheridia. The red—probably protectant—pigmentation of antheridia is conserved across Charophyceae. Chara tomentosa is, however, unique in exhibiting this …

What we really know about the dormancy, reproduction, germination and cultivation of charophytes (Characeae)

Anja Holzhausen

This expanded review aims to provide information on previous basic research by charophyte experts in the areas of reproduction, dormancy, germination of oospores and cultivation. Therefore, published information, the author’s PhD thesis and further results have been combined to summarise the current …

Chara canescens part I: Oospore differentiation of parthenogenic and dioecious strains and salt-dependent oospore sizes

Anja Holzhausen, Roman E. Romanov, Hendrik Schubert

Abstract Chara canescens Loisel. is one of two European species of the section Desvauxia R.D. Wood of the genus Chara L. Whereas most populations of C. canescens reproduce parthenogenetically, a few sites with sexual reproducing populations are known. Studies of European C. …

What we really know about the dormancy, reproduction, and germination of charophytes and the new method of ECO-IN-VITRO-CULTIVATION

Anja Holzhausen

This paper aims to provide information on previous basic research by charophyte experts mainly in the field of reproduction, dormancy, and germination of oospores. Therefore, published information, the author’s PhD thesis and further new results have been combined to summarise the state …

Insight into the nodal cells transcriptome of the streptophyte green alga Chara braunii S276

Daniel Heß, Anja Holzhausen, Wolfgang R. Hess

Charophyceae are the most complex streptophyte algae, possessing tissue-like structures, rhizoids and a cellulose-pectin-based cell wall akin to embryophytes. Together with the Zygnematophyceae and the Coleochaetophycae, the Charophyceae form a grade in which the Zygnematophyceae share a last common ancestor with land …

Plastid DNA sequences and oospore characters of some European taxa of Tolypella section Tolypella (Characeae) identify five clusters, including one new cryptic Tolypella taxon from Sardinia, but they do not coincide with current morphological descriptions

Anja Holzhausen, Petra Nowak, Andreas Ballot, R. Thomas Becker et autres

In Europe, the genusTolypella(Characeae) comprises four to eightTolypellataxa in sectionsRothiaandTolypellathat have been distinguished by vegetative morphology and gametangial characters such as antheridial size and oospore wall ornamentation. However, morphological differentiation is difficult in some cases due to overlapping and variable vegetative features, …
