New #ISEPpapers! Hijacking and integration of algal #plastids and #mitochondria in a polar planktonic host: Ananya Kedige Rao et al. https://www.cell.com/current-biology/fulltext/S0960-9822(25)00392-6
"Hosts steal active plastids, mitochondria, and nuclei from the microalga #Phaeocystis... Stolen plastids increase in volume, and their photosynthetic activity is boosted... Stolen mitochondria transform into a network in close association with plastids"
Vitamin #B12 adaptability in Antarctic #algae has implications for #climate_change, life in the Southern Ocean.

Vitamin B12 deficiency in people can cause a slew of health problems and even become fatal. Until now, the same deficiencies were thought to impact certain types of algae, as well. A new study has examined the algae Phaeocystis antarctica's (P. antarctica) exposure to a matrix of iron and vitamin B12 conditions. Results show that this algae has the ability to survive without B12, something that computer analysis of genome sequences had incorrectly indicated.
A Bloom in a Changing Barents Sea

"The #BarentsSea usually has 2 major bloom seasons, with #diatoms peaking in May, June, then giving way to #coccolithophores by August. As the #climate changes, #scientists are using #satellites to track how #phytoplankton populations are responding. They observed large shifts in the location of summer #coccolithophore blooms to the northeast & an increasing presence of #Phaeocystis normally found in warmer waters"
