Abstract
In this work, we examined the impact of sorghum gain germination on kafirins solubility and digestibility. Two genotypes differing in their proteins and tannins contents were germinated under controlled conditions up to radicle emergence. Biochemical, physicochemical, and in vitro digestibility tests were applied on the germinated grains. Microscopic examination of grains endosperm revealed that germination resulted in pitted starch granules and protein matrix slackening. Apart cystine and the amount of free thiol groups which increased significantly, the overall amino acids composition remained rather unchanged, just as the kafirins solubility and size distribution. In contrast germination was demonstrated to improved significantly the in vitro protein digestibility, even after cooking and especially for the genotype poor in tannin. Without inducing major physicochemical changes, germination enhanced kafirins susceptibility to gastrointestinal proteases. Germination may be a way to improve the nutritional value of sorghum.

[PMID: 38611404 PMCID: PMC11011791 DOI: 10.3390/foods13071100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Revised: 03/28/2024] [Accepted: 03/28/2024] [Indexed: 04/14/2024] Open
Abstract
The male sterility line is a vital approach in the genetic breeding of sorghum. The husking process affects the grain's nutritional composition, emphasizing the intricate relationship between genetic enhancement and dietary requirements. The current study assessed the influence of the Husking Fraction Time Unit (HFTU) process, which was set at 30 (S) and 80 (S) time units per second (S). The study assessed the impact of the (HFTU) process on fifty-one inbred line sorghum race varieties, which implied diverse nutritional profiles considering the pericarp color variations. The assessment of the nutritional profile involved dry matter, total protein, and minerals (P, K, S, Ca, Mg, Na, Fe, Zn, and Mn). The variety groups showed a significance value of p ≤ 0.05, indicating the study hypothesis's truth. While results demonstrated substantial impacts implied by the Husking Fraction Time Unit (HFTU) technique, the occurrence was noted when the dry matter percentage was increased in the husked products, specifically the endosperm (grits) and bran. Conversely, the protein variation percentage between the bran and endosperm (grits) for the S. bicolor race was calculated at 33.7%. In comparison, the percentage was 11.8% for the Kafirin race. The 80 (S) time unit, on the other hand, had an observable effect on the mineral reconcentration when the Kafirin race had the highest averages of K mg/kg-1, Ca mg/kg-1, and Fe mg/kg-1, which were 5700.5 mg/kg-1, 551.5 mg/kg-1 and 66.5 mg/kg-1, respectively. The results of this study could benefit breeders and nutrition specialists in developing genotypes and processing sorghum grains, promoting research, and aiding several industrial sectors owing to the grain's adaptability and nutritional properties.

A large sequenced mutant library - valuable reverse genetic resource that covers 98% of sorghum genes. THE PLANT JOURNAL : FOR CELL AND MOLECULAR BIOLOGY 2024; 117:1543-1557.

Abstract
Mutant populations are crucial for functional genomics and discovering novel traits for crop breeding. Sorghum, a drought and heat-tolerant C4 species, requires a vast, large-scale, annotated, and sequenced mutant resource to enhance crop improvement through functional genomics research. Here, we report a sorghum large-scale sequenced mutant population with 9.5 million ethyl methane sulfonate (EMS)-induced mutations that covered 98% of sorghum's annotated genes using inbred line BTx623. Remarkably, a total of 610 320 mutations within the promoter and enhancer regions of 18 000 and 11 790 genes, respectively, can be leveraged for novel research of cis-regulatory elements. A comparison of the distribution of mutations in the large-scale mutant library and sorghum association panel (SAP) provides insights into the influence of selection. EMS-induced mutations appeared to be random across different regions of the genome without significant enrichment in different sections of a gene, including the 5' UTR, gene body, and 3'-UTR. In contrast, there were low variation density in the coding and UTR regions in the SAP. Based on the Ka /Ks value, the mutant library (~1) experienced little selection, unlike the SAP (0.40), which has been strongly selected through breeding. All mutation data are publicly searchable through SorbMutDB (https://www.depts.ttu.edu/igcast/sorbmutdb.php) and SorghumBase (https://sorghumbase.org/). This current large-scale sequence-indexed sorghum mutant population is a crucial resource that enriched the sorghum gene pool with novel diversity and a highly valuable tool for the Poaceae family, that will advance plant biology research and crop breeding.

Chemical Composition, Antioxidant Potential, and Nutritional Evaluation of Cultivated Sorghum Grains: A Combined Experimental, Theoretical, and Multivariate Analysis. Antioxidants (Basel) 2023; 12:1485. [PMID: 37627480 PMCID: PMC10451854 DOI: 10.3390/antiox12081485] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 07/13/2023] [Accepted: 07/19/2023] [Indexed: 08/27/2023] Open
Abstract
Sorghum grain (Sorghum bicolor L. Moench) is a gluten-free cereal with excellent nutritional value and is a good source of antioxidants, including polyphenols, as well as minerals with proven health benefits. Herein, the phenolic composition, elemental profile, and antioxidant activity of sixteen food-grade sorghum grains (S1-S16) grown under agroecological conditions in Serbia were determined. Nine phenolic compounds characteristic of sorghum grains, such as luteolinidin, 5-methoxyluteolinidin, luteolidin derivative, luteolidin glucoside, apigeninidin, 7-methoxyapigeninidin, apigeninidin glucoside, and cyanidin derivative, were quantified. The antioxidant potential of the analyzed sorghum grains was evaluated by UV/Vis (DPPH, ABTS, and FRAP) and Electron Paramagnetic Resonance spectroscopy (hydroxyl and ascorbyl radical scavenging assays). The content of macro- and microelements was determined by Inductively Coupled Plasma Optical Emission spectroscopy. Theoretical daily intakes of selected major and trace elements were assessed and compared with the Recommended Daily Allowance or Adequate Intake. Sample S8 had the highest amount of phenolic compounds, while S4, S6, and S8 exhibited the strongest antioxidative potential. The sorghum studied could completely satisfy the daily needs of macro- (K, Mg, and P) and microelements (Se, Zn, Fe). Pattern recognition techniques confirmed the discrimination of samples based on phenolic profile and elemental analysis and recognized the main markers responsible for differences between the investigated samples. The reaction between hydroxyl radicals and luteolinidin/apigeninidin was investigated by Density Functional Theory and thermodynamically preferred mechanism was determined.
