“…According to Dehesh et al (2001), a factor which may limit the content of fats could be the absence of malonyl-CoA, produced from acetyl-CoA. The accumulation of 6-phosphogluconate dehydrogenase (6PGDH) or NADP-IDH increased in response to short-term stress but decreased under long-term stress (Popova et al 2001;Huang et al 2003;Hou et al 2007). The role of NADP-IDH, activated during stress, most probably consists in accelerating a-ketoglutarate synthesis, which is needed for reorganization of the cell's metabolism and induction of metabolic pathways, important for adaptation processes, especially when proline and c-aminobutyric acid (GABA) are accumulated during stress; 2-ketoglutarate is a nitrogen-free precursor for proline and GABA (Popova et al 2001).…”

Another important element in plants' response to abiotic stresses is the pentose phosphate pathway, in which 6PGDH may function as a factor regulating the efficiency of this pathway (Huang et al 2003;Hou et al 2007).…”

“…The response of plants to environmental stresses includes alterations in the expression of genes as well as physiological, biochemical and molecular adaptation processes, for example changes in the synthesis of proteins (synthesis of adaptation and protection proteins), accumulation of soluble protection substances and in the cellular metabolism (Hasegawa et al 2000;Kato-Noguchi 2000b;Popova et al 2001;Kawaguchi et al 2004). All such modifications are controlled at the transcriptional, post-transcriptional and post-translation levels (Kawaguchi et al 2004).…”

Plants growing under natural conditions are exposed to a variety of stresses, which can lead to undesirable changes in the physiological processes and yielding. These changes can be regulated at different levels, resulting in the synthesis of specific proteins which participate in the plant's response to stress. The purpose of this study was to determine changes in the accumulation of proteins in germinating pea (Pisum sativum L.) seeds under optimal and osmotic (short-and long-term) stress conditions as well as recovery following a short-term stress. For identification of the proteins, two-dimensional electrophoresis and mass spectrometry (MALDI-TOF) were employed. Germination in optimal conditions increased the accumulation of several proteins involved in glycolysis, Krebs cycle, synthesis of fatty acids, cell growth, cellular transport and detoxification. Osmotic stress, in turn, depressed the accumulation of proteins involved in glycolysis, synthesis of fatty acids, detoxication, methionine conversions, cellular transport, translation, growth control and of cytoskeletal proteins, but raised the accumulation of enzymes of the tricarboxylic acid cycle as well as proteins participating in signal transduction and protection (chaperones). One protein, 6a-hydroxymaackian-3-O-methyltransferase, which is involved in the synthesis of pisatin, was present only under osmotic stress conditions and recovery. Pisatin is synthesized mainly in response to microbiological infections and under stress conditions, indicating its key role in the acquisition of stress tolerance by plants.

“…The ontogenesis of aphids ( Aphidinea ), usually consisting of 6 instars (egg, 4 larval instars and imago) (Figs 15 , 16 ), is complicated in most cases by cyclic parthenogenesis with a regular alternation of bisexual and parthenogenetic generations and with or without a regular alternation of the host plants ( Mordvilko 1914 , 1934 , 1935 ; Pesson 1951 ; Popova 1967 ; Blackman 1987 ; Moran 1992 ). In the archaic aphid superfamily Phylloxeroidea , both parthenogenetic and bisexual generations lay eggs (Fig.…”

“…The arostrate instars in aphids are known as a whole bisexual arostrate generation in all species of Phylloxeridae and Pemphigidae ( Mordvilko 1914 ; Popova 1967 ). All four larval instars and imago (of both sexes) in this generation do not have mouthparts and do not increase the body size during molts (Fig.…”

The paper is a third part of the themed issue “Aberrant cytogenetic and reproductive patterns in the evolution of Paraneoptera”, prepared by a Russian-Bulgarian research team on the basis of long-term collaborative studies. This chapter reviews different peculiar aberrations in the ontogenesis of Paraneoptera, such as the appearance of the quiescent apodal and/or arostrate instars, exuviatrial, pupillarial and pseudopupillarial development, cyclic parthenogenesis, etc. The material and methods, terminology and the nomenclature of the used taxonomic names are listed in the first chapter of the issue (Gavrilov-Zimin et al. 2021).

The educational subsystem is recognized as the most important driving force of regional socio-economic development. The policy of the Government of the Tyumen Region is aimed at promoting the development of international relations, expanding foreign economic relations, and popularizing export activities. For the regional economy development through the foreign economic activity sphere, we need personnel who meet the needs of regional employers, meet modern requirements for the specialist training quality, and have the competencies of the future. A special place in the foreign economic activity infrastructure is assigned to customs authorities. It is noted that modern strategic trends in the development of the customs service of Russia require the modernization of the educational process of training personnel for this area. The issues of a competence model formation are considered on the example of training a customs specialist at Tyumen State University, in which the emphasis is shifted to new groups of competencies, relationship of individual competencies, and synergetic effect of their interaction.
