Algal Phylogeny and the Origin of Land Plants1
1998年1月1日 · Many tiny, single-celled algae live within a complex exoskeleton made of CaCO 3 or silica, which accumulates over time in deep sea deposits in the world's oceans (coccolithophorids, diatoms). The fossil remains of these algae are routinely used for paleoclimatic reconstructions and to predict climate change.
Genomes of early-diverging streptophyte algae shed light on …
2019年12月16日 · In phylogenomic analyses, the earliest-diverging streptophyte algae are represented by a clade comprising two monospecific genera, Mesostigma and Chlorokybus 14, 15, 16, 17. Both are structurally...
Evolution of the Chlorophyta: Insights from chloroplast …
2017年3月14日 · A reliable phylogenetic tree of Chlorophyta is important to understand the early evolution of green algae. However, resolving the phylogenetic relationships among the major clades of the Chlorophyta has been shown to be a difficult task, because these ancient lineages radiated rapidly, and possible multiple extinction events occurred from ...
Chloroplast Phylogenomic Inference of Green Algae Relationships …
2016年2月5日 · Our proposed phylogenetic tree of Chlorophyta will offer new insights to investigate ancient green algae evolution and our analytical framework will provide a useful approach for evaluating...
Protist diversity: Novel groups enrich the algal tree of life
2021年6月7日 · In recent years, the diversity of eukaryotic microbes has been greatly expanded by recognising or discovering new major branches of the algal tree of life. A new study defines the phylogenetic home for an elusive marine planktonic lineage previously known only by plastidial rRNA genes, placing it in a new class of the phylum Haptophyta.
An introduction to algal phylogeny and phylogenetic methods
This chapter is an introduction to algal phylogeny and to the most common methods used in the construction of evolutionary trees. The subsequent 13 chapters in this book deal with specific aspects of the phylogeny of cyanobacteria (the primary source of the algal plastid), plastids and all the major algal lineages. Algae. — Endosymbiosis.
Phylogeny and evolution of streptophyte algae - Oxford Academic
In this article, we take a deep dive into the phylogeny and evolution of streptophyte algae. Given their deep evolutionary splits, there are divergences into order-level lineages of streptophyte algae that pre-date by far the origin of land plants.
The algae, which can be loosely defined as photosyn-thetic eukaryotes/protists excluding the land plants, have a bewildering array of cell morphologies and life cycles and live in a multitude of habitats. The major lineages of the algae are the Chlorophyta (green algae), Rhodophyta (red algae), Glaucocystophyta, Euglenophyta, Chlorarach-
From algae to angiosperms–inferring the phylogeny of green plants
2014年2月17日 · Next-generation sequencing has provided a wealth of plastid genome sequence data from an increasingly diverse set of green plants (Viridiplantae). Although these data have helped resolve the phylogeny of numerous clades (e.g., green algae, angiosperms, and gymnosperms), their utility for inferring relationships across all green plants is uncertain.
The Algal Tree of Life from a Genomics Perspective
2020年6月4日 · It is now widely recognized that photosynthetic eukaryotes (algae and plants) have polyphyletic origins in the eukaryotic tree of life (ETOL). The primary endosymbiosis that gave rise to the first photosynthetic organelle (plastid) occurred ca. 1.6 billion years ago via the capture and retention of a free-living cyanobacterium by a single ...
