Plants are often harmed by pathogens, herbivores, or unfavorable climate conditions. Their delicate lifestyle makes them vulnerable to such conditions more often. But, have you ever questioned how wounded plants heal? Now, a team of researchers from the Institute of Science and Technology Austria (IST Austria) has found that the hormone auxin, which is essential in plant growth and development, and pressure variations play a vital role in the plant’s way of regenerating. In an experiment, the scientists wounded a thale cress root with a laser and then tracked cells during regeneration with a microscope. The findings shed light on how roots manage to heal wounds and hence sustain in sandy soil or the presence of root-attacking herbivores.
