[Kinetics of mitotic rhythmic activity in oat (Avena sativa) coleoptiles following irradiation]. 2001

G D Slyniavchuk, and D M Grodzins'kyĭ

The analysis of different intensity (10-200 Gy) irradiation influence on rhythmical processes in mitotic activity of oats coleoptiles was carries out. Obtained results indicate that irradiation disorders phase and amplitude of the cell division rhythm in investigated material. This disturbance, as judged by doze dependence, is associated with unknown molecular structures.

D008940	Mitotic Index	An expression of the number of mitoses found in a stated number of cells.	Index, Mitotic,Indices, Mitotic,Mitotic Indices
D010507	Periodicity	The tendency of a phenomenon to recur at regular intervals; in biological systems, the recurrence of certain activities (including hormonal, cellular, neural) may be annual, seasonal, monthly, daily, or more frequently (ultradian).

D005720	Gamma Rays	Penetrating, high-energy electromagnetic radiation emitted from atomic nuclei during NUCLEAR DECAY. The range of wavelengths of emitted radiation is between 0.1 - 100 pm which overlaps the shorter, more energetic hard X-RAYS wavelengths. The distinction between gamma rays and X-rays is based on their radiation source.

D018548	Cotyledon	A part of the embryo in a seed plant. The number of cotyledons is an important feature in classifying plants. In seeds without an endosperm, they store food which is used in germination. In some plants, they emerge above the soil surface and become the first photosynthetic leaves.
