Fig. 7
Expression profiles of SsCOI1s under drought and cold stresses. The trimmed mean of M-values (TMM) shown in the box represented the expression levels of SsCOI1s. The color bar represented the normalized values (log2 TMM). The clustering tree on the left side of the figure was constructed using the maximum likelihood method (JTT + G model, complete deletion, and 1000 bootstrap replicates) by MEGA 6.60, and different colors and letters (A, B, and D) on the phylogenetic tree represented three groups of SsCOI1s. Drought_0 d, Drought_2 d, Drought_6 d, Drought_10 d, Recovery_10 d, Cold_0 h, Cold_0.5 h, Cold_1 h, Cold_6 h represented the time that sugarcane cultivated under drought or cold treatments
