Heat stress induces organelle alterations in Macrocystis pyrifera gametophytes

open access: yesJournal of Phycology, Volume 62, Issue 4, Page 1129-1146, August 2026.
Abstract Kelp, brown macroalgae in the order Laminariales, provide ecosystem services vital to ocean biodiversity. However, kelp forests worldwide are declining due to abiotic stressors such as ocean warming. In this study, we present results from high‐resolution confocal microscopy and in vivo imaging system imaging using protocols developed to ...

Plastid Evolution

Annual Review of Plant Biology, 2008
The ancestors of modern cyanobacteria invented O2-generating photosynthesis some 3.6 billion years ago. The conversion of water and CO2 into energy-rich sugars and O2 slowly transformed the planet, eventually creating the biosphere as we know it today.

Plastid peptidoglycan

Biochimica Et Biophysica Acta - General Subjects, 2010
It is now widely accepted that an endosymbiotic cyanobacterium evolved into the plastid of the primary photosynthetic eukaryotes: glaucocystophytes, red algae, and green plants. It has been thought that during the evolution of plants, the peptidoglycan wall (or murein) was lost from the endosymbiont immediately after the branching off of the ...

Shopping for plastids

Trends in Plant Science, 2007
Recent suggestions that endosymbionts in a diatom and an amoeba represent independent origins of plastids from those in plants and algae raise again the question of how many times plastids have evolved. In this Opinion article, we review the evidence for a single origin or multiple origins of primary plastids.

On the origin of plastids

Origins of Life, 1975
The buoyant density in CsCl of ribosomes from chloroplasts of the green alga Chlorella pyrenoidosa and two species of higher plants, Pisum sativum and Chenopodium album, has been studied. From the relative protein content it was calculated that 70S ribosomes from chloroplasts are much smaller than 80S cytoplasmic ribosomes (3.0-3.1 X 10(6) and 4.0 X 10(
