In a #chloroplast-based #immune mechanism, OSB1 stabilizes AGD2-LIKE DRP 1 to promote defense signaling. The #viral effector βC1 disrupts this process by hijacking OSB1, thus weakening #plant #immunity.

can animals photosynthesise? musican moglii told me about the leaf slug. like the sea slug it gets energy by doing photosynthesia! i thought only plants can convert water, minerals and sunlight into glucose and oxygen.. to find out that also the spotted salamander and the pea aphid have symbiotic relationship with algae to do kleptoplasty (that is how scientist call the process of stealing the photosynthetic organelles (chloroplasts) from the algae) made me jealous. if i could choose a superpower this kleptoplasty would come straight after being invisible.

Light-regulated #chloroplast morphodynamics in a single-celled dinoflagellate https://www.pnas.org/doi/10.1073/pnas.2411725121

"The structure that allows the chloroplast to make necessary changes was found to be a network of thin filaments. Together, these filaments form a material that can easily contract and expand in all directions."

A single cell's siesta: How non-moving single-celled organisms manage to avoid bright light

Too much of a good thing is no good at all. Living organisms enjoy sunlight—in fact, they need it to stay alive—but they tend to avoid light that is too bright. Animals go to their shelter, humans have a siesta, even plants have mechanisms to avoid an overdose of light. But how do non-moving single-celled organisms deal with light that is too intense? Researchers at the University of Amsterdam have discovered the surprising answer.
