New discovery paves way for crops to grow in damaged soils 11 February 2021 | The technology holds huge potential for farmers in the UK, Professor Sacha Mooney says Scientists have discovered a signal that causes roots to stop growing in hard soils which can be ‘switched off’ to allow them to punch through, a finding which may have ‘huge implications’ for agriculture. Researchers from the University of Nottingham have discovered that roots do not stop growing in hard soils because of physical obstruction, but instead as a reaction to the plant hormone ethylene. Ethylene is given off ...

Study paves way for compaction-resistant crops >More in © Tim Scrivener New opportunities to create compaction-resistant crops that are able to grow in the hardest of soils could be on the horizon thanks to a scientific breakthrough. Researchers discovered how the plant signal ethylene causes roots to stop growing in hard soils. But this signal can be “switched off” to allow roots to punch through compacted soil. Researchers used X-ray computed tomography scanners at the Hounsfield Facility at the University of Nottingham to visua...

The discovery of just one coronavirus case was enough to plunge Brisbane into a three-day lockdown – but this was no ordinary infection.
