Dynamic transcript abundance during cellularisation of the developing barley endosperm: Temporal regulation of cell wall synthesis

ABSTRACT: Grain development in the Poaceae defines important end-use properties such as yield, quality and nutritive value. Microarray analyses have been performed on barley grain endosperm extracts from three to eight days after pollination (DAP), when cellularization of the syncytium occurs through the growth of cell walls around individual nuclei. Profiling of transcripts differentially expressed over time reveal 56 specific modules of genes that cluster into 15 groups. Expression patterns have been superimposed upon microscopy data, which identify the timing of key stages in grain development. Thus, cellularization is complete at six DAP, aleurone-related genes can be detected at seven to eight DAP, and starch synthase and hordein genes increase dramatically at seven and eight DAP, respectiv
