This response is
called effector - triggered immunity, or ETI, and ultimately results in the plant killing off its own affected cells to prevent the bacteria from replicating and spreading.
In many cases the damage is caused by a particular group of immune cells
called effector memory T - cells.
The researchers studied two types of cells
called effector T cells, which activate the immune system to defend our body against different pathogens, and regulatory T cells, which help control the immune system and prevent it from attacking healthy parts of its environment.
Our research enhances the traditional understanding of the plant defense system and describes a new concept describing how plants protect themselves against the pathogens that grow in the space outside plant cells (the apoplast)-- a new concept
called effector - triggered defense or ETD.»
The new concept is
called effector - triggered defense or ETD.
In their earlier work, the Halle lab already proved that the bacteria introduce numerous harmful proteins, so -
called effectors, into plant cells via a specialised secretion system which works like a molecular syringe.
They will also prepare a list of the genetic codes of the fungus — the so -
called effectors — that are responsible for the ability of the fungus to adapt to new wheat varieties.
