The advantages of free threshing in wheat led to the selection of the domesticated Q allele, which is now present in almost all modern wheat varieties. Q and the pre-domestication allele, q, encode an AP2 transcription factor, with the domesticated allele conferring a free-threshing character and a subcompact (i.e. partially compact) inflorescence (spike). We demonstrate that mutations in the m...
Mike came from a farming background in the north of England and spent much of his childhood on the family farm during World War II (1939– 1945).

The cleaning device is an important part of combine harvesters, as its superior or inferior performance directly affects the harvester greatly. With increasing rice yield, current single-duct declines greatly, and causes a large grain sieve loss level direct for farms. To optimize existing to meet feeding rate requirement, firstly, terminal velocity MOG (material other than grain) different var...
