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

open access: yesRoyal 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.

open access: yesCells, 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.

Potential Use of Marine Seaweeds as Prebiotics: A Review

open access: yesMolecules, 2020
Human gut microbiota plays an important role in several metabolic processes and human diseases. Various dietary factors, including complex carbohydrates, such as polysaccharides, provide abundant nutrients and substrates for microbial metabolism in the ...

Photosynthesis of an endolithic Chlorococcum alga (Chlorophyta, Chlorococcaceae) from travertine calcium carbonate rocks of a tropical limestone Spring

open access: yesApplied Phycology, 2022
A green alga, Chlorococcum sp. (Chlorococcales, Chlorophyceae), was grown from scrapings of the travertine rocks from the outlet stream of the Emerald Pool, Khlong Thom Nuea, Khlong Thom District Krabi province in Southern Thailand – a classic karstic ...

The complete mitogenomes of the green algae Jenufa minuta and Jenufa perforata (Chlorophyceae, incertae sedis) reveal a variant genetic code previously unrecognized in the Chlorophyceae

open access: yesMitochondrial DNA. Part B. Resources, 2020
We sampled the first mitogenomes from a novel lineage of the Chlorophyceae that is sister to Sphaeropleales. Although the Jenufa perforata (27,180 bp) and Jenufa minuta (41,488 bp) mitogenomes differ markedly in size, gene order and intron content, their

Order, please! Uncertainty in the ordinal-level classification of Chlorophyceae [PDF]

open access: yesPeerJ, 2019
Background Chlorophyceae is one of three most species-rich green algal classes and also the only class in core Chlorophyta whose monophyly remains uncontested as gene and taxon sampling improves.

Structural variation and evolution of chloroplast tRNAs in green algae [PDF]

open access: yesPeerJ, 2021
As one of the important groups of the core Chlorophyta (Green algae), Chlorophyceae plays an important role in the evolution of plants. As a carrier of amino acids, tRNA plays an indispensable role in life activities. However, the structural variation of

Morphological description and ecology of some rare macroalgae in south-central Spanish rivers (Castilla-La Mancha Region)

open access: yesAnales del Jardín Botánico de Madrid, 2013
The Castilla-La Mancha Region (south-central Spain) is scarcely studied in terms of freshwater algae. However, both the implementation of the Water Framework Directive (2000/60/CE) and the evaluation of the ecological state of European aquatic ecosystems

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

open access: yesMitochondrial 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.

ALGAL STUDY IN SPRINGS AND STREAMS IN SHAQLAWA DISTRICT, ERBIL PROVINCE-IRAQ III- CHLOROPHYCEAE WITHOUT ZYGNEMATALES

open access: yesThe Iraqi Journal of Agricultural science, 2023
Freshwater algae (Chlorophyceae-except Zygnematales) were collected from 18 sites (12 springs and 6 streams) in Shaqlawa district within Erbil Province, Kurdistan Region of Iraq from September-2019 to August-2020.
