Interruption of magnesium supply at heading influenced proteome of peripheral layers and reduced grain dry weight of two wheat (Triticum aestivum L.) genotypes.

Abstract excerpt

UNLABELLED: Magnesium (Mg), an indispensable mineral for plant growth, is concentrated in the peripheral layers (PLs) of the mature grain of wheat. The supply of Mg was interrupted from plant heading to maturity and a proteomic approach was used to investigate the PLs at three stages of development. Two genotypes with contrasting concentrations of Mg in the grain were studied: Apache (low Mg) and MgHL (high Mg)....
