New research on #protists sheds light on #DeepSea energy sources https://www.whoi.edu/press-room/news-release/foraminifer/

Array of metabolic pathways in kleptoplastidic #foraminifera supports #chemoautotrophy in dark, euxinic seafloor sediments https://academic.oup.com/ismej/article/19/1/wrae248/7923457 by Fatma Gomaa et al.

"This species takes up unrelated organism’s #chloroplasts — #organelles that perform #photosynthesis... We know #kleptoplasty is happening here, but we needed to understand why this foraminifer is so successful in the dark, without oxygen"

June 1958: 'Fatty Acids in #Chloroplasts and #Leaves'. - W. Mary Crombie

...featuring the fatty acid composition of #Holly (Ilex aquifolium)

I couldn't find a picture of Mary, but I did find her husband's memoir published by the Royal Society. In 1953, Mary Crombie (née Wood), married her fellow fatty acid scientist and coauthor, Leslie Crombie - a #chemistry power couple! 🧪

Scientists have revealed a new role of chloroplasts in plant immunity against viral and bacterial pathogens. When plants sense infection, chloroplasts form tube-like projections called "stromules," which cluster around the nucleus, serving as conduits for pro-defense signals. Despite previous knowledge of stromule involvement, a key protein crucial for stromule formation during immunity remained unidentified until now.

Plant chloroplasts promise potential therapy for Huntington’s disease

A chloroplast enzyme safeguards plants against pathological protein aggregation that causes Huntington’s and other neurodegenerative diseases / new research may have found a way to “copy” the mechanism for application in human cells.

Relationship status: *It's complicated*🤷

Lee et al. work on untangling how the targeting specificity of signal-anchored #proteins is determined for specific targeting to #mitochondria and #chloroplasts.

How cells gain control over their bacterial #symbionts https://phys.org/news/2022-12-cells-gain-bacterial-symbionts.html

Host-#symbiont interactions in #Angomonas deanei include the evolution of a host-derived dynamin ring around the #endosymbiont division site https://www.cell.com/current-biology/fulltext/S0960-9822(22)01776-6

Similar to #mitochondria and #chloroplasts, the #genome of the #bacterium is already reduced... The integration is sufficiently advanced for cell division to occur synchronously: When the host divides, so does the bacterium.

Using array tomography, researchers create a 3D reconstruction of the light-dependent positioning of #chloroplasts, peroxisomes, nuclei, and vacuoles in #Arabidopsis mesophyll #cells. In PNAS Nexus: https://academic.oup.com/pnasnexus/article/1/5/pgac225/6748211
