A comparative test of the gamete dynamics theory for the evolution of anisogamy in Bryopsidales green algae [PDF]

Royal Society Open Science, 2021
Gamete dynamics theory proposes that anisogamy arises by disruptive selection for gamete numbers versus gamete size and predicts that female/male gamete size (anisogamy ratio) increases with adult size and complexity.

Cryopreservation of the Microalgae Scenedesmus sp.

Cells, 2023
Each phytoplankton species presents a different behavior and tolerance to the cryopreservation process. Therefore, in a species-specific protocol, it is essential to ensure both growth and post-thawing cell viability.

Complete mitogenomes of the chlorophycean green algae Bulbochaete rectangularis var. hiloensis (Oedogoniales) and Stigeoclonium helveticum (Chaetophorales) provide insight into the sequence of events that led to the acquisition of a reduced-derived pattern of evolution in the Chlamydomonadales and Sphaeropleales

Mitochondrial DNA. Part B. Resources, 2020
Mitogenome evolution in the Chlorophyceae is characterized by the acquisition of a reduced-derived pattern by the Chlamydomonadales + Sphaeropleales clade.
