Expression patterns of DEGs in developing maize endosperm.

<p>Fifteen expression patterns were characterized by the fluctuating expression of gene sets at 5, 10, 15 and 20 DAP. The DEG sets showed different tends of transition from down- to up-regulated states or from up- to down-regulated states over the developmental stages (TL-14 and 15). The up- and down-regulated gene sets are staggered or are depicted consecutively over the developmental stages of maize endosperm. The scaled expression levels of the DEGs are provided on the <i>y-</i>axis, the developmental stages are shown on the <i>x</i>-axis, the coloured lines represent the individual gene expression clusters, and the trend in expression of each gene set is depicted as a black line. ‘n’ represents the number of DEGs.
