“…The primary targets of Egyptian clover breeding programs are high biomass production, ease of cultivation, and substantial nitrogen fixation capacity (Muhammad et al, 2014). Since this species is allogamous in nature, like red and white clovers, a mass selection method is usually applied in the breeding programs, resulting in the maintenance of genetic diversity within a cultivar to avoid inbreeding depression by self-crossings (Abdalla and Abd El-Naby Zeinab, 2012). Genomics is a promising tool for accelerating breeding programs by playing a crucial role in the rapid development of new varieties and ensuring resilience and adaptability in changing climates (Thudi et al, 2021).…”

Egyptian clover (Trifolium alexandrinumL.), also known as berseem clover, is an important forage crop to semi-arid conditions that was domesticated in ancient Egypt and introduced and well adapted to numerous countries. Despite its agricultural importance, genomic research on Egyptian clover has been limited to developing efficient modern breeding programs. In the present study, we constructed near-complete telomere-to-telomere-level genome assemblies for two Egyptian clover cultivars, Helaly and Fahl. Initial assemblies were established by using highly-fidelity long-read technology. To extend sequence contiguity, we developed a gap-targeted sequencing (GAP-Seq) method, in which contig ends are targeted for sequencing to obtain long reads bridging two contigs. The total length of the resultant chromosome-level assemblies was 547.7 Mb for Helaly and 536.3 Mb for Fahl. These differences in sequence length can be attributed to the expansion of DNA transposons. Population genomic analysis using single-nucleotide polymorphisms revealed 38 highly conserved genomic regions within Helaly. Growth- and stress response-associated gene ontologies were enriched in the 38 regions, indicating that these genes may determine the unique characteristics of Helaly. Comprehensive genomic resources can provide valuable insights into genetic improvements in Egyptian clover and legume genomics.

The purpose of this investigation was to determine ¹H-NMR profiling and antioxidant activity of the most common types of honey, namely, citrus honey (HC1) (Morcott tangerine L. and Jaffa orange L.), marjoram honey (HM1) (Origanum majorana L.), and clover honey (HT1) (Trifolium alexandrinum L.), compared to their secondary metabolites (HC2, HM2, HT2, respectively). By using a ¹H-NMR-based metabolomic technique, PCA, and PLS-DA multivariate analysis, we found that HC2, HM2, HC1, and HM1 were clustered together. However, HT1 and HT2 were quite far from these and each other. This indicated that HC1, HM1, HC2, and HM2 have similar chemical compositions, while HT1 and HT2 were unique in their chemical profiles. Antioxidation potentials were determined colorimetrically for scavenging activities against DPPH, ABTS, ORAC, 5-LOX, and metal chelating activity in all honey extract samples and their secondary metabolites. Our results revealed that HC2 and HM2 possessed more antioxidant activities than HT2 in vitro. HC2 demonstrated the highest antioxidant effect in all assays, followed by HM2 (DPPH assay: IC50 2.91, 10.7 μg/mL; ABTS assay: 431.2, 210.24 at 50 ug/mL Trolox equivalent; ORAC assay: 259.5, 234.8 at 50 ug/mL Trolox equivalent; 5-LOX screening assay/IC50: 2.293, 6.136 ug/mL; and metal chelating activity at 50 ug/mL: 73.34526%, 63.75881% inhibition). We suggest that the presence of some secondary metabolites in HC and HM, such as hesperetin, linalool, and caffeic acid, increased the antioxidant activity in citrus and marjoram compared to clover honey.
