Plant regenerative process a as a genetic character

Abstract

PIant regenerate process as a genetic character. The necessity and possibility of the genetic analysis of the plant regeneration process has been considered in this paper. The anatomical and morphological characteristics of the plant regenerative processes has been obtained and possible parths for their classification have been introduced. The method and experimental model has been proposed to investigate the genetic of the regent ration. The intraspecific variability on the root and callus formation (regenerative ability) has been demonstrated Following the study of the radish, tomato cotyledons and strawberry stalks. The differences in callus formation have been revealed during the study of the radish reciprocal hybrids, different cotyledons of the same plant (radish, tomato), cotyledons from the different age (tomato). This phenomenon was called an ontogenic mutant. Callus formation in plant is considered as an example of the ontogenetic mutant having special gene function programm unlike the intact plants. The study of the ontogenetic mutants is one of paths leading to genetic of the plant development. This is also the way for studying the genetic physiological nature of genotype mutants.

Рассмотрено явление регенерации и возможности его анализа в генетике. Дана анатомо-морфологическая характеристика процессов регенерации у растений. Установлена внутривидовая генотипическая изменчивость по способности регенерации у семядолей редиса, томатов. Введено и экспериментально обосновано понятие онтогенетического мутанта по регенерационной способности. Онтогенетические мутанты по регенерационной способности выявлены при сравнительном изучении регенерации семядолей реципрокных гибридов (редис), семядолей одного проростка (редис, томаты), семядолей проростков разного возраста (томаты). Каллусный рост у растений рассматривается как пример онтогенетического мутанта с особой программой функции генов по сравнению с органами интактного проростка
