The intensity of RNA synthesis was studied in different regions of anuclear fragments of the Acetabularia mediterranea stem under their local illumination. The local illumination was shown to activate RNA synthesis and formation of distal-medial gradients of this synthesis in the illuminated regions of the fragments to a much greater extent than in their darkened regions. The formation of the gradient in the illuminated region took place even if the growth in this region was insignificant and was not accompanied by the cap formation. The results obtained suggests the absence of obligatory correspondence between the ability of morphogenesis and the gradient of RNA synthesis.
在地中海伞藻茎的无核片段的不同区域，对其进行局部光照后，研究了RNA合成的强度。结果表明，局部光照能激活RNA合成，并在片段的光照区域形成这种合成的远侧-中间梯度，其程度远大于黑暗区域。即使光照区域的生长不明显且未伴随帽的形成，光照区域仍会形成梯度。所得结果表明形态发生能力与RNA合成梯度之间不存在必然对应关系。
