Light-regulated gravitropism in seedling roots of maize.

abstract：:Changes in the rate and pattern of protein synthesis and in translatable mRNA population during cold acclimation of alfalfa (Medicago falcata cv Anik) seedlings have been examined. There appears to be a positive correlation between the increase in ability to synthesize proteins at 4 degrees C and the increase in freez...
