Varietal differences in protein polymer built-up of wheat at different temperature and nitrogen regimes during grain filling
Year: 2008
Type: article
Abstract: The amount and size distribution of polymeric proteins, influenced by cultivar, temperature and nitrogen timing, is an important factor in determining gluten strength in wheat.In mature wheat grains, the distribution of the monomeric and polymeric proteins as well as their solubility play a critical role in governing wheat flour properties and uses.Four varieties of wheat (two early and two late), differing in high-molecular-weight glutenin subunit composition (2+12 versus 5+10) were grown at four nitrogen regimes and two temperature regimes in order to determine the manner in which differences in mature protein composition were the result of differences in accumulation of proteins during grain filling.Combination of temperature and nitrogen regimes leads to changes in amount and size distribution of polymeric proteins in mature grains of wheat.A relationship is present between polymerisation of proteins during grain maturation and amount and size distribution of polymeric proteins in the mature grains.
