“+” or no sign in the regulation column represents upregulation (higher expression) of a gene in the current sample as compared with the control sample
“−” sign indicates downregulation (lower expression) of a gene in the current sample as compared with the control sample
Upregulation of a “gene” in experimental sample as compared with control also indicates the downregulation of that same “gene” in the control sample as compared with experimental sample and vice versa. Gene expressions at different stages of growth viz SI, SII, and SIII for each cultivar were pooled together for comparative gene regulation study
