Differentially expressed genes between AJ and GZ spike tissues.

<p>(A) MA plot of differentially expressed transcripts identified in AJ and GZ. The X axis represents the mean expression level, and the Y axis represents the log₂ fold-change of GZ transcripts over AJ. Red and blue dots represent differentially expressed genes (DEGs) that are significantly abundant in GZ and AJ, respectively, at p-value < 0.05. Horizontal lines and the values to the right represent the average M-values of corresponding groups of DEGs and non-DEGs. (B) Gene ontology (GO) classification of the DEGs. GO terms of <i>Z</i>. <i>japonica</i> unigenes are based on significant hits against the NR database. The right <i>y</i>-axis indicates the number of upregulated genes in AJ (black) and GZ (grey), respectively. The left <i>y</i>-axis indicates the percentage of each group from the total.
