Tomato (Solanum lycopersicum) is a perishable fruit because of its fast water loss and susceptibility to pathogens in the post-harvest stage, which leads to huge economic losses every year. In this study, firstly from 19 tomato cultivars, we screened out two cultivars, Riogrand and SalarF1, having long and short shelf-life spans, respectively. Secondly, shelf-life analysis was carried out for both cultivars at room temperature. Results exhibited that Riogrand showed higher firmness and less weight loss than SalarF1. The ethylene production was higher in SalarF1, compared with Riogrand during post-harvest storages. We performed transcriptomic analysis of both cultivars in different storage stages. We discovered 2913, 2188, and 11,119 differentially expressed genes (DEGs) for three post-harvest stages (0, 20, and 40 Days Post-Harvest (DPH)), respectively. These genes are enriched in ethylene biosynthesis and response, as well as cell wall-related genes. Ethylene response factor (ERF) ERF2 and ERF4 were highly expressed in SalarF1 with a short shelf life in 40 DPH, and the ethylene biosynthetic genes ACO1, ACO4, ACS6, and ACS2 were significantly upregulated in SalarF1. Regarding cell wall loosening and cell wall-related genes XTH3, XTH7, XTH23, 1,3;1,4-beta-D-Gluc-like, pGlcT1, Cellulase, PGH1, PL5, PL-like 1, PL-like 2 exhibited the highest levels of significance, being notably upregulated in the last stage of SalarF1. The quantitative real-time polymerase chain reaction (qRT-PCR) analysis validated these gene expressions, which is in line with the transcriptome analysis. The findings suggested that the extension of tomato fruit shelf life is mostly dependent on ethylene biosynthesis, signaling pathway genes, cell wall loosening, and cell wall-associated genes.

The study area belongs to the north Afghanistan having complex tectonic setting, because of separation of the Afghanistan plate from Pangea in Early Permian and its subsequent northward journey and collision with Eurasian plate. The rock exposed in the area belongs to Paleozoic, Mesozoic to Quaternary with Proterozoic basement. Particularly the Permian succession of Afghanistan is rich in fusulinids (larger foraminifera), is age diagnostic, provides strong biostratigraphic tool for the Permian deposits, and has paleobiogeographic applications. The Bamian zone of north Afghanistan has good exposure to Middle Permian and is designated as Bolula and Khaja Ghar Formation is undertaken in this study. The Bolula Formation overlies the greenschist and basalts, composed mainly of carbonate rocks (Dolostone and limestone), having massive limestone, with some quartz and secondary calcite vein in the succession. The intermittent siliciclastic wedges within the carbonate succession are identified as input within the platform with tectonic pulses in the hinterland. Bolula and Khaja Ghar succession is divided into 8 lithofacies ( Facies A to H) and 6 carbonate Facies viz. Sparry calcites limestone, Micritic limestone, Fossiliferous limestones (Biomicrite), Peloidal limestone (Fecal pellets), Interlaminated micritic and sparite limestone, and sandy limestone (micritic). The Bolula and Khaja Ghar Formation in the Bamian area have deposited in a shallow marine shelf environment because of predominance of carbonate rocks and presence of shallow-water marine fossils including fusulinids, small benthic foraminifera, algae, bivalve, brachiopods fragments, corals and bryozoans, etc. In the Bamian zone the unconformity between Upper Carboniferous and Lower Permian;indicates extensive gap in sedimentation, traceable to many parts of Afghanistan as unconformity or tectonic contact is considered here as sequence boundary.
