A major international study has explained how bread wheat helped to transform the ancient world on its path to becoming the iconic crop that today helps sustain a global population of eight billion.
"Our findings shed new light on an iconic event in our civilisation that created a new kind of agriculture and allowed humans to settle down and form societies," said Professor Brande Wulff, a wheat researcher at KAUST and one of the lead authors of the study which appears inProfessor Cristobal Uauy, a group leader at the John Innes Centre and one of authors of the study said:"This work exemplifies the importance of global collaboration and sharing of data and seeds across...
The chance hybridisation on the banks of the southern Caspian Sea spawned an agricultural revolution. Cultivation of bread wheat rapidly spread across a wide new range of climates and soils as farmers enthusiastically adopted this dynamic new crop, with its high gluten content that creates an airier elasticated breadmaking dough.
From this panel the researchers selected 46 accessions reflecting the species traits and genetic diversity, to create a Pangenome, a high-quality genetic map of Aegilops tauschii. "Without the genetic viability that this diversity brings, we would most likely not eat bread on the scale we do today. Otherwise, bread wheat today would be a regional crop -- important to the Middle East but I doubt that it would have become globally dominant without this plasticity that enabled bread wheat to adapt."
"We used the L3 tauschii accessions as a guinea pig to track and trace the hybridizations using 80,000 bread wheat landraces," said Professor Krattinger.
