Washington, September 17: A new research, from the John Innes Centre and the Central Science Laboratory in the US, could help breeders to develop pea varieties that would be able to withstand drought stress and climate change.
The researchers used NMR spectroscopy to produce a profile of the levels of all the different small molecules or metabolites in pea plant leaves.
This profile, known as the metabolome, was then compared with that from plants subjected to controlled drought stress.
The study found several key plant metabolites increased under drought stress, some of which had not previously been shown to be involved.
Less water, especially at critical times in the growing season, means lower yield and quality.
