One of the directions in plant biotechnological research is the use of callus cultures in vitro. The callus is an integrated system that is formed both exogenously (as a result of the proliferation of surface cells of various tissues of the plant organism) and endogenously (in the depth of these tissues). Initially, callus consists of homogeneous cells gradually transformed into a system of groups of heterogeneous cells with specific morphogenetic potencies. These potencies are realized by various ways of morphogenesis in vitro, including those leading to the formation of full-fledged plants-regenerants. In this review, using cereals as an example, we analyze the literature and our data on the use of calli in vitro as experimental systems for studying the plant stress-resistance to abiotic factors, especially to the drought factor. The advantages and limitations of using callus cultures in vitro are considered. The prospects of studying the mechanisms of action of abiotic stressors and resistance to them at the cellular and tissue levels under model conditions of callus culture in vitro are shown. Attention is paid to the assessment of the drought resistance of cereals under selective conditions simulating drought in vitro by such a parameter as the growth activity of calli. The issue of studying anti-stress effects in callus cultures in vitro is analyzed on the example of brassinosteroids. The prospects of using the model system “immature embryo in vivo–embryonic morphogenic callus in vitro” for rapid assessment of the effect of anti-stress plant growth regulators are considered. It is emphasized that the basis for using calli as the model system is both the significant role of the cell in all morphogenetic events of the plant organism in vivo and in vitro and the similarity of the responses of plants in vivo, calli in vitro, regenerants of callus origin in vitro and ex vitro.

The problem of cultivated plants resistance to heat as the effect of high air temperatures leading to physiological drought is extremely relevant not only in the conditions of predicted climate aridization, but also when studying the effects of relatively short-term “heat waves”. Modern breeding is focused on the creation of high-yielding heat-resistant varieties of cultivated plants, especially cereals as the main world food resource. During breeding developments, it is necessary to first identify heat-resistant cereal genotypes for their insertion in the appropriate programs. The article provides a critical analysis of a number of approaches presented in the literature to identify such genotypes (modeling of the effect of the high temperature stress factor in experimental conditions in situ; the use of anthers in such conditions as the generative structures more sensitive to the effects of this stress factor in comparison with vegetative organs), which can be assessed as methodological. In addition, from the standpoint of descriptive and experimental plant embryology, the use of interrelated concepts (developed by T.B. Batygina, 2014 and earlier) is proposed as the promising methodological approach: the assessment of the anther as the complex integrated tissue system and the presence of critical stages in the development of this system.
