“…Previous studies have suggested that alternative splicing may play important roles in plant adaptation to environmental stresses [33,34]. A recent study showed that rapid and dynamic alternative splicing impacts the cold response in Arabidopsis [1]. Similarly, in this study, we found that the alternative splicing level in the CT sample was higher than that in the RT sample ( Fig.…”

“…Plants from temperate regions can increase their freezing tolerance by being exposed to chilling and non-freezing temperatures, which is known as cold acclimation [3]. By contrast, plants of tropical and subtropical origins, such as rice, maize, and C 4 grasses, largely lack such a capacity for cold acclimation and are sensitive to chilling stress [1].…”

Background: Pennisetum giganteum, an abundant, fast-growing perennial C 4 grass that belongs to the genus Pennisetum, family Poaceae, has been developed as a source of biomass for mushroom cultivation and production, as a source of forage for cattle and sheep, and as a tool to remedy soil erosion. However, having a chilling-sensitive nature, P. giganteum seedlings need to be protected while overwintering in most temperate climate regions. Results:To elucidate the cold stress responses of P. giganteum, we carried out comprehensive full-length transcriptomes from leaf and root tissues under room temperature (RT) and chilling temperature (CT) using PacBio Iso-Seq long reads. We identified 196,124 and 140,766 full-length consensus transcripts in the RT and CT samples, respectively. We then systematically performed functional annotation, transcription factor identification, long noncoding RNAs (lncRNAs) prediction, and simple sequence repeat (SSR) analysis of those full-length transcriptomes. Isoform analysis revealed that alternative splicing events may be induced by cold stress in P. giganteum, and transcript variants may be involved in C18 unsaturated fatty acid biosynthesis and metabolism pathways at chilling temperature in P. giganteum. Furthermore, the fatty acid composition determination and gene expression level analysis supported that C18 unsaturated fatty acid biosynthesis and metabolism pathways may play roles during cold stress in P. giganteum. Conclusions:We provide the first comprehensive full-length transcriptomic resource for the abundant and fastgrowing perennial grass Pennisetum giganteum. Our results provide a useful transcriptomic resource for exploring the biological pathways involved in the cold stress responses of P. giganteum.

“…Dehydrins play an important role in protecting plants from dehydration stresses, including stress imposed by freeze-drying (Wisniewski et al, 2003;Tunnacliffe, Wise, 2007). Their accumulation is one of the fundamental responses of plants to cold stress (Maleki, Ghorbanpour, 2018).…”

The aim of the research was to study the dynamics of dehydrine proteins of apple (Malus spp.) trees in Southern Cisbaikalia conditions. Siberian berry apple tree and domestic or cultivated apple tree as well as their interspecific hybrids of various crossing generations, that showed differences in winter hardiness in field studies, were used as the object of the research. Samples of plant material were collected monthly (September to May) during two experimental years. The results showed that the qualitative composition of dehydrins in the bark of an apple tree did not depend on the cultivar. Proteins with a mass of 63, 60, 52, 45, 34 and 32 kD were determined in the dehydrin spectrum of all the studied apple tree genotypes. Dehydrin with a molecular mass of 52 kDa was present throughout the dormancy. The number of other proteins varied depending on the season. Significant differences were found for proteins with masses of 60 and 34 kDa. The revealed peculiarities of the 34 kDa protein content can be associated with the adaptive potential of apple trees in the conditions of Southern Cisbaikalia.

“…There is evidence that the content of soluble proteins in plant tissues increases during the period of autumn hardening. In the pre-winter period, specific biochemical reactions are activated in plants, newly synthesized proteins, enzymes, and isozymes appear, allowing resistant varieties to cope with unfavorable temperature conditions [11,12]. It has been shown that the synthesis of proteins, dehydrins, increases during hardening and, possibly, they prevent the formation of ice in plant cells [13].…”

The purpose of these studies is to assess the adaptive resistance of the apple tree to winter stresses in terms of physiological and biochemical parameters, to identify the most resistant varieties for cultivation in the Krasnodar region. Objects of research are apple varieties of various origins: Orfey, Idared, Ligol, Prikubanskoe. It was found that the cryoprotective function of water-soluble sugars was maximally manifested in the varieties Orfey and Ligol, their content increased by 2.56 and 2.7 times, respectively. Soluble proteins made the greatest contribution to the formation of a protective response in Orfey and Prikubanskoye varieties in January, their content increased 1.8 and 1.9 times, respectively, compared to December. The protective function of anthocyanins was maximally manifested in December in the Orfey variety, in the bark of which their content increased by 5.6 times. Physiological and biochemical adaptation of apple varieties to low negative temperatures of the winter period is achieved by increasing the content of water-soluble sugars, proteins in anthocyanins in the bark and buds. According to the obtained data, the apple varieties Orfey and Prikubanskoye showed themselves to be more adaptive in comparison with other studied varieties and are recommended for cultivation in the Krasnodar region.
