For the first time, scientists have decoded the full DNA sequence of the potato plant. Details
of the achievement are published in the journal, Nature. The discovery could help to boost
food production. This report is from Jon Ironmonger:
The humble potato is in fact the world's fourth largest food crop, with a global annual yield
of around 330 million tonnes.
In an international project lasting several years, researchers have successfully recorded its
complete chemical blueprint, deciphering and organising hundreds of millions of pieces of
genetic coding.
By mapping the plant's genome scientists can locate the genes that control various traits, like
colour, starchiness and flavour, leading to the creation of improved varieties at a much
quicker pace.
Professor Iain Gordon from the James Hutton Institute in Dundee, which headed the British
team, said the genome sequence would allow breeders to develop new types that are more
nutritious, resistant to pests and diseases and easier to cultivate.
He said the breakthrough could help to meet the challenge of feeding the world's soaring
population.
