More than a decade ago, plant geneticists noticed something peculiar when they looked at grafted plants. Where two plants grew together, the cells of each plant showed signs of having picked up ...

Past genetic experiments have shown that, when plants are grafted together, entire genomes can move between the host and the graft, but it was not clear how the genetic material was traveling. In a ...

Scientists discovered that mitochondria inside plant cells can pull oxygen away from chloroplasts, revealing a hidden mechanism that may help plants adapt to stress.

Plants constantly juggle oxygen inside their cells, but scientists have now discovered a surprising twist in how that balance works. Researchers at the University of Helsinki found that ...

All plant cells obtain their energy mainly from two organelles they contain - chloroplasts (responsible for photosynthesis) and mitochondria (responsible for the biochemical cycle of respiration that ...

Organelles in cells were originally often independent cells, which were incorporated by host cells and lost their ...

Two studies by scientists at the University of Chicago have demonstrated a new way to look into the inner workings of cells—in particular, to track the flow of ions inside the many tiny organelles ...

Cells in symbiotic partnership, nested one within the other and functioning like organelles, can borrow from their host’s genes to complete their own metabolic pathways. There are few relationships in ...

Princeton researchers created new tools to study the separation of liquids inside of cells into compartments, so-called membraneless organelles. The significance of this intracellular liquid phase ...
