Abstract
The wound response in two-week-old C{sub 3} (peanut and soybean) and C{sub 4} (sorghum and corn) plants was followed in leaf segments (5 {times} 3 mm) labelled for 2 h with ({sup 35}S)methionine at 0, 2, 4 or 6 h after cutting. Absorption of the radiolabel and its subsequent incorporation into protein reached steady-state levels within 4 to 6 h. The high molecular weight proteins associated with the stress response were induced both by cutting and by exposure of the leaves to high temperatures (40{degree} and 45{degree}C). In sorghum and corn, cutting also increased the synthesis of the 98 and 102 kD forms of phosphoenolpyruvate carboxylase, but only the latter form was stimulated by high temperature. Although several low molecular weight polypeptides were synthesized in response to heat shock, they were not induced in any of the four species by wounding. The control mechanisms involved in the transient would response are currently under investigation.
