The 26 SUCEST cDNA libraries were grouped according to the similarity of the sugarcane organs used as source for mRNA extraction: AD/HR (AD1 and HH1 libraries); AM/LB (AM1, AM2, LB1, and LB2 libraries); CL (CL6 library); FL (FL1, FL3, FL4, FL8, and FL8 libraries); LV (LV1, LR1, and LR2 libraries); RT (RT1, RT2, and RT3 libraries); SD (SD1 and SD2 libraries); ST (ST1, ST3, SB1, RZ1, RZ2, and RZ3 libraries). The sum of the percentages per category (column X) is higher than 100% because some SAS appear in more than one category. SD, standard deviation.
