Cereal Genomics: An Overview uri icon

abstract

  • Cereals are widely cultivated and produce annually, 1800 to 1900 milliontonnes of food grains worldwide (see Table 1; FAO- websitehttp://apps.fao.org). Cereals also represent 60% of the calories and proteinsconsumed by human beings. They include a variety of crops including rice,maize, wheat, oats, barley, rye, etc., but excluding millets like pearl milletand other minor millets. In the past, cereals have been a subject of intensivecytogenetic investigations that are now extended further in the genomics erausing powerful tools of molecular biology. The progress in cereal genomicsresearch during the last two decades, involving the use of molecular markersfor a variety of purposes, and the whole genome sequencing in rice has beenremarkable indeed. The results of genomics research resolved many aspects,which the conventional cytogenetics failed to resolve. For instance, thisinvolved initially the preparation of molecular maps, which were utilizedextensively for
