Differential proteins between storage roots and fibrous roots of sweet potato in proteome. a Number of differential proteins between D1 stage sorage roots and fibrous roots (D1 vs F), D3 stage sorage roots and fibrous roots (D3 vs F), D5 stage sorage roots and fibrous roots (D5 vs F) as well as D10 stage sorage roots and fibrous roots (D10 vs F). b Clusters of differential proteins. F_1, F_2 and F_3, fibrous root; D1_1, D1_2 and D1_3, initial storage root (diameter is about 1 cm); D3_1, D3_2 and D3_3, storage root (diameter is about 3 cm); D5_1, D5_2 and D5_3, storage root (diameter is about 5 cm); D10_1, D10_2 and D10_3, storage root (diameter is about 10 cm). Coloring correlates with the membership value, the higher the membership value, the closer the expression pattern among the protein members
