Figure 6. Protein profiles of cytoplasmic protein in leaves of three Kentucky bluegrass cultivars (A, ‘Brilliant’, B, ‘Eagleton’, and C, ‘Midnight’) during heat stress. Lanes: (1) 20°C for 7 d; (2) 40°C for 7 d; (3) 40°C for 14 d; (4) 40°C for 21 d; (5) 40°C for 28 d; and (6) marker protein. Equal amounts of protein (45 µg) were loaded in each lane. Solid arrows indicate newly induced proteins during heat stress and hollow arrows indicate degraded constitutive proteins during heat stress. MW, molecular weight; kDa, kiloDalton; Marker, standard protein with known molecular weight.
