Human bodies defend themselves using a diverse population of immune cells that circulate from one organ to another, responding to everything from cuts to colds to cancer. But plants don’t have this ...

Scientists have created a new atlas of plant cells during immune response, in turn discovering a new rare cell state, called Primary IMmunE Responder (PRIMER), that acts as an immune response hub ...

Sánchez Alvarado and his team found minor transcriptional changes when they compared the cells remaining after distal versus proximal ... suggesting that there really are mechanisms for sensing injury ...

Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls ...

This was not simply a result of the injury caused by the laser ... a signal that prevents differentiation of the root stem cells. Thus plant stem cells depend on the function of other, neighboring ...

But plants don't have this luxury. Because plant cells are immobile, each individual cell is forced to manage its own immunity in addition to its many other responsibilities, like turning sunlight ...
