Researchers at NUI Galway are part of a global scientific team, which has succeeded in decoding the genome of a crop, known as the Pigeonpea, the staple food for millions people worldwide.
The mapping of the pigeonpea genome is a breakthrough in agricultural development and will have a major impact on improved crop productivity, tackling pests and disease constraints in production, and improved resistance to harsh environments and the future variable climate. It is now set to join the world's league of major food crops with the completion of its genome sequence.

Research Institute for the Semi-Arid Tropics (ICRISAT), an Indian-based
agricultural research institute, led a global partnership and spent a few years
analyzing the genome. NUI Galway Botany and Plant scientist, Mark T.A.
Donoghue, Reetu Tuteja and Charles Spillane helped in decoding this plant's
genetic code and have their work has been published in the highest-ranked
journal in the area, “Nature Biotechnology”.
The so-called ‘orphan crop’ is the first non-industrial crop to have a completed genome sequence. "While crops such as pigeonpea are essential to food and livelihood security in developing countries, such crops of the world’s poorest peoples are considered orphan crops as there is limited scientific research applied to the development of improved higher productivity varieties due to a lack of commercial incentives.” said Prof Spillane.
“The
mapping of the pigeonpea genome is a breakthrough that could not have come at a
better time. Now that the world is
faced with hunger and famine, particularly in the Horn of Africa brought about
by the worst drought of the decades, science-based, sustainable agricultural
development solutions are vital in extricating vulnerable dryland communities
out of poverty and hunger for good”; said Icrisat director
general William Dar, who visited NUIG earlier this year.

“Modern
crop improvement technologies for smallholder farmer crops such as pigeonpea
will be crucial to speed up the development of improved varieties that can
provide high yields and improved livelihoods,” he said.
Some of the research partners included
BGI – Shenzhen (China), the National University of Ireland Galway, University
of Georgia, University of California-Davis, Cold Spring Harbor Laboratory, and
National Centre for Genome Resources, and was also supported by the CGIAR
Generation Challenge Programme based in Mexico.
