Science to help wheat sleep through pre harvest rain

Plain text source: 
Two genes related to dormancy (which prevents untimely germination leading to pre-harvest sprouting) have been discovered.. New gene-discovery techniques also mean an accelerated process for isolating potentially important wheat genes for other traits.. In terms of knowing which grain-growing regions these genes will work in, given that not all varieties are suited across the country, Dr Gubler says it is not known how these genes actually confer dormancy, although the researchers do know the expression of the genes is suppressed by high temperatures during grain development - and this then elevates the risk of PHS...
