ns = non-significant when FDR ≤ 1; Log(FC) is the log₂ ratio of gene transcript between sensitive genotypes [CK60 (1), BTx623 (2), low-NUE bulk (7)] and tolerant genotypes (San Chi San (3), China17 (4), KS78 (5), High-NUE bulk (6)]; If Log(FC) <0, negative values indicate transcript is abundant in tolerant genotypes and if Log(FC) >0, positive values indicate transcript is abundant in sensitive genotypes.
