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 ...

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 ...

At first glance, plant and animal cells have a lot in common: they’re both highly organized, keep their DNA tucked away in an envelope, and are kinda juicy inside. But plant cells have evolved some ...

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 ...

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

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 ...

Bacteria are only the only organisms that are able to 'fix' nitrogen, or remove it from the atmosphere and convert it into a useful form. While some plants seem to fix nitrogen, it is actually ...

Picture a living cell as if it were a city. If you were the urban planner for this (very little, very alive) city, one of the things you would have to decide is how to allocate space for different ...
