a-d The volcano plot of DEGs for drought stress and Si Vs drought treatments of and for control vs. Silicon alone treatments of (c) ILL 6002 and (d) ILL 7537. The abscissa indicates the level of expression as log2 of the folds change (log 2F) and the ordinates are -log10 (p-value). Each symbol represents a gene. The red circle represents the down regulated DEGs, blue squares represent the up regulated DEGs, and green triangle represent non-DEGs. DEG- differentially expressed gene
