The tomato is a fruit vegetable rich in nutritional and medicinal value grown in greenhouses and fields worldwide. It is severely sensitive to heat stress, which frequently occurs with rising global warming. Predictions indicate a 0.2 °C increase in average surface temperatures per decade for the next three decades, which underlines the threat of austere heat stress in the future. Previous studies have reported that heat stress adversely affects tomato growth, limits nutrient availability, hammers photosynthesis, disrupts reproduction, denatures proteins, upsets signaling pathways, and damages cell membranes. The overproduction of reactive oxygen species in response to heat stress is toxic to tomato plants. The negative consequences of heat stress on the tomato have been the focus of much investigation, resulting in the emergence of several therapeutic interventions. However, a considerable distance remains to be covered to develop tomato varieties that are tolerant to current heat stress and durable in the perspective of increasing global warming. This current review provides a critical analysis of the heat stress consequences on the tomato in the context of global warming, its innate response to heat stress, and the elucidation of domains characterized by a scarcity of knowledge, along with potential avenues for enhancing sustainable tolerance against heat stress through the involvement of diverse advanced technologies. The particular mechanism underlying thermotolerance remains indeterminate and requires further elucidatory investigation. The precise roles and interplay of signaling pathways in response to heat stress remain unresolved. The etiology of tomato plants’ physiological and molecular responses against heat stress remains unexplained. Utilizing modern functional genomics techniques, including transcriptomics, proteomics, and metabolomics, can assist in identifying potential candidate proteins, metabolites, genes, gene networks, and signaling pathways contributing to tomato stress tolerance. Improving tomato tolerance against heat stress urges a comprehensive and combined strategy including modern techniques, the latest apparatuses, speedy breeding, physiology, and molecular markers to regulate their physiological, molecular, and biochemical reactions.

“…Development and application of modern Omics-and DNA technologies (Goel et al, 2020;Faryad et al, 2021), used for the improvement of crop plants, made it possible to propose the so-called strategy '5Gs for crop genetic improvement', which include five areas, i.e., 1G -genome, 2G -germplasm or ‗2G-hermaplasma', 3G -genes, 4G -genomic selection, and 5G -gene editing (Varshney et al, 2020). Relatedly, to implement the direction of 2G-hermaplasma, it is necessary to use effective tools to study a large genetic array of crops.…”

The progressive study determined the gliadin 'profile' and genetic diversity based on allelic variations of gliadin-coding loci in spring soft wheat (Triticum aestivum L.) selection from Russian and Kazakh origins. A total of 139 samples obtained from a spring soft wheat collection consisting of 62 from Russia and 77 from Kazakhstan were studied. As a result of electrophoretic analysis in Russian wheat, the share of monomorphic gliadin cultivars was 63% and polymorphic was 37%. However, in the Kazakh wheat collection, the share of polymorphic gliadin cultivars was 26%. The alleles were mostly found among the Russian cultivars, i.e., Gli-А1f (46.9%), Gli-В1е (43.7%), Gli-В1b (30.8%), Gli-D1а (61.0%), Gli-А2l (17.0%), Gli-А2m (16.9%), Gli-В2o (16.1%), and Gli-D2q (19.8%). In wheat genotypes collected from Kazakhstan, the following alleles dominated, i.e., Gli-А1f (47.4%), Gli-В1е (72.0%), Gli-D1а (61.7%), Gli-А2l (25.3%), Gli-А2s (16.2%), Gli-В2r (25.7%), and Gli-D2a (40.3%). The study compiled the so-called 'ideal' electrophoretic spectrum of gliadin for several countries to visualize the 'portrait' of wheat, created based on common blocks of gliadin identified by the researchers at different times. It assumed that cultivars close to the 'ideal' spectrum in gliadin alleles should have a complex of economically valuable features. For example, the spectrum of Russian wheat consists of the blocks of components controlled by alleles, i.e., f, e, a, q, o, e. As for the Kazakh wheat, its 'ideal' spectrum (f, e, a, l, r, a) coincides with the spectrum of Russian wheat at the loci Gli-1, as Russian cultivars were often taken as parental genotypes by the Kazakhstan breeders.
