The major challenges that agriculture is facing in the twenty-first century are increasing droughts, water scarcity, flooding, poorer soils, and extreme temperatures due to climate change. However, most crops are not tolerant to extreme climatic environments. The aim in the near future, in a world with hunger and an increasing population, is to breed and/or engineer crops to tolerate abiotic stress with a higher yield. Some crop varieties display a certain degree of tolerance, which has been exploited by plant breeders to develop varieties that thrive under stress conditions. Moreover, a long list of genes involved in abiotic stress tolerance have been identified and characterized by molecular techniques and overexpressed individually in plant transformation experiments. Nevertheless, stress tolerance phenotypes are polygenetic traits, which current genomic tools are dissecting to exploit their use by accelerating genetic introgression using molecular markers or site-directed mutagenesis such as CRISPR-Cas9. In this review, we describe plant mechanisms to sense and tolerate adverse climate conditions and examine and discuss classic and new molecular tools to select and improve abiotic stress tolerance in major crops.

“…The use of molecular markers is a well-established practice to estimate the homozygosity and to genotype both the parents (to be crossed) and the resulting offspring [ 46 , 63 ]. Markers are also widely used for the evaluation of DUS parameters (diversity, uniformity and stability) in the phase of variety constitution [ 64 ], for the legal registration of new varieties [ 65 ] and as an effective tool for addressing legal disputes related to improper use of registered varieties [ 66 ].…”

The Apiaceae taxon is one of the most important families of flowering plants and includes thousands of species used for food, flavoring, fragrance, medical and industrial purposes. This study had the specific intent of reviewing the main genomics and transcriptomic data available for this family and their use for the constitution of new varieties. This was achieved starting from the description of the main reproductive systems and barriers, with particular reference to cytoplasmic (CMS) and nuclear (NMS) male sterility. We found that CMS and NMS systems have been discovered and successfully exploited for the development of varieties only in Foeniculum vulgare, Daucus carota, Apium graveolens and Pastinaca sativa; whereas, strategies to limit self-pollination have been poorly considered. Since the constitution of new varieties benefits from the synergistic use of marker-assisted breeding in combination with conventional breeding schemes, we also analyzed and discussed the available SNP and SSR marker datasets (20 species) and genomes (8 species). Furthermore, the RNA-seq studies aimed at elucidating key pathways in stress tolerance or biosynthesis of the metabolites of interest were limited and proportional to the economic weight of each species. Finally, by aligning 53 plastid genomes from as many species as possible, we demonstrated the precision offered by the super barcoding approach to reconstruct the phylogenetic relationships of Apiaceae species. Overall, despite the impressive size of this family, we documented an evident lack of molecular data, especially because genomic and transcriptomic resources are circumscribed to a small number of species. We believe that our contribution can help future studies aimed at developing molecular tools for boosting breeding programs in crop plants of the Apiaceae family.

Cucumis sativus L. belong to Cucurbitaceous. The Phytochemical profiling of white foamy substance was performed using HR-LCMS, details of projecting compounds with MS spectra, peak list, and compound structure were studied. The prominent constituent analysis (PCA) of the investigative data displayed the existence of Triterpenes: Gitoxigenin (7.76ppm), Strophanthidin(13.79ppm), Cucurbita in-C (-0.8ppm), Cucurbita in-E(5.53ppm), and Cardiac glycosides: and Digitoxigenin(-2.13ppm) in 10µl of the loaded sample.100 other composites were identified by accurate mass of Q-TOF/MS and confirmed by database compounds (IRM calibration) which comprises, abscisic acid amino acids, fatty acids pyridylactic acid etc. Strophanthidin in the premier attention in the white foamy extract is a noteworthy finding where it has interaction with various proteins in biochemical reactions. This study reports the customary implication of removing white foamy substances before slicing for ingestion. It is used as both vegetables as well as fruit in Indian traditional medicine. It is a source of bioactive compounds.
