Abstract:
:The optimum temperature of protein synthesis in wheat seedlings (Triticum aestivum L.), measured as (14)C-leucine incorporation, depends on the growing temperature. Plants grown at reduced temperature (4 C) reach their optimum at 27.5 C, whereas plants kept at 36 C have the highest rate of protein synthesis at 35 C. The transition is gradual. The activation energy of protein synthesis for seedlings grown at medium or reduced temperature is lower (about 11 kcal/mole), than for plants grown at higher temperatures (15 keal/mole). The decline of the rate of protein synthesis beyond the temperature optimum is also affected by the growth temperature; only plants kept at 30 or 36 C show a sharp decrease with increasing slope; plants kept at 4, 10, and 20 C exhibit a linear and comparatively moderate decline.
