Gain and loss of polyadenylation signals during evolution of green algae
Background The Viridiplantae (green algae and land plants) consist of two monophyletic lineages: the Chlorophyta and the Streptophyta. Most green algae belong to the Chlorophyta, while the Streptophyta include all land plants and a small group of ...

Asymmetric Subcellular mRNA Distribution Correlates with Carbonic Anhydrase Activity in Acetabularia acetabulum [PDF]
Abstract The unicellular green macroalga Acetabularia acetabulum L. Silva is an excellent system for studying regional differentiation within a single cell. In late adults, physiologically mediated extracellular alkalinity varies along the long axis of the alga with extracellular pH more alkaline along the apical and middle regions of ...

Preservation and remodelling of chloroplast lipids in photosynthetic sea slug host cells
The capacity to retain long-term functional algal chloroplasts within animal cells is a singular trait of certain Sacoglossa sea slugs. The sequestered chloroplasts (kleptoplasts) confer photosynthetic capacity to the host.

Abstract Sacoglossa sea slugs have garnered attention due to their ability to retain intracellular functional chloroplasts from algae, while degrading other algal cell components. While protective mechanisms that limit oxidative damage under excessive light are well documented in plants and algae, the photoprotective strategies employed by these ...

Algae represent more than 41% of marine biological invasions worldwide. If non-native algae become an invasive and dominant species, they will inevitably affect the characteristics of the ecosystem. The study aimed to evaluate the potential effect of the

kurkku, a Phenotype of Acetabularia acetabulum That Is Arrested in Vegetative Growth, Can Be Rescued with Wild-Type Cytoplasm [PDF]
We isolated several spontaneous phenotypes in the giant unicell Acetabularia acetabulum that have vegetative terminal morphologies. Because they arrest in vegetative development, these cell lines are effectively immortalized. However, they had to be rescued before they could be studied via classical genetics because no heterozygotes from the original ...

A vacuolar H+-pyrophosphatase in Acetabularia acetabulum: molecular cloning and comparison with higher plants and a bacterium [PDF]
Further elucidation of the H+-PPase of A. acetabulum An almost complete cDNA clone (pPPI ( AcVP gene), 3104 bp is of great interest from an evolutionary perspective of the in length/open reading frame from 795 to 2960 bp/721 amino H+-PPases from photosynthetic bacteria to higher plants.

Oscillations in ultraweak photon emission of Acetabularia acetabulum (L.).
Ultraweak photon emission of dark-incubated A. acetabulum cells were measured with the use of a sensitive electronphotomultiplier of the Hamamatsu 550 type. The photon count series were subjected to Fourier analysis for 2-1020 sec period range. The average level of photon emission in samples containing 50 cells was approximately.
