How does ionizing radiation affect amyloidogenesis in plants?

Purpose: Ionizing radiation is a harsh environmental factor that could induce plant senescence. We hypothesized that radiation-related senescence remodels proteome, particularly by triggering the accumulation of prion-like proteins in plant tissues. The object of this study, pea ( L.

[Transgenic plants tolerant to abiotic stresses].

References are analyzed concerning production and studying of transgenic plants tolerant to various kinds of abiotic stresses; mechanisms of plant protection against stresses; the genes encoding the great spectrum of compounds giving to plants ability to survive in conditions of the stresses considerably repressing development and even lethal for control plants.

[Number of aberrations per cell as a parameter of chromosome instability. 2. Comparative analysis of the factors of different nature].

The average number of aberrations per aberrant cell was concluded to carry out information on chromosome instability peculiarities induced by different mutagens as it was shown in our previous work. The purpose of the current study was to present comparative analysis of intercellular distribution of number of aberrations and their theoretical approximations. Distribution of numbers of aberrations per cell in Allium cepa L.

[The number of aberrations in aberrant cells as a parameter of chromosomal instability. 1. Characterization of dose dependency].

Analysis of chromosome instability (CI) is of great importance in view of pollution of the environment by genotoxic factors. Frequency of aberrant cells, spectrum of chromosome aberrations, damages of aberrant cell and distribution of aberrations in the cells are the most conventional parameters of CI. We have carried out the comparative analysis of the frequency of aberrant cells and the dynamics of aberrant cell damages induced by different mutagenic factors (alpha-irradiation from 241Am, gamma-irradiation from 60Co and tioTEPA) in Allium-test.

[Cytogenetic effects of 241Am in the Allium test].

The purpose of this study was to elucidate the genome damage induced by 241Am-irradiation using different parameters of cytogenetic evaluation in Allium-test. The root tip cells test-system for the cytogenetic effects studying was used. 241AmCl3 of different concentrations was used (1.
