Sorghum comprises 31 species that exhibit considerable morphological and ecological diversity. Te phylogenetic relationships among Sorghum species still remain unresolved due to lower information on the traditional DNA markers, which provides a limited resolution for identifying Sorghum species. In this study, we sequenced the complete chloroplast genomes of Sorghum sudanense and S. propinquum and analyzed the published chloroplast genomes of S. bicolor and S. timorense to retrieve valuable chloroplast molecular resources for Sorghum. Te chloroplast genomes ranged in length from 140,629 to 140,755 bp, and their gene contents, gene orders, and GC contents were similar to those for other Poaceae species but were slightly diferent in the number of SSRs.

  • African Sorghum-Based Fermented Foods: Past, Current and Future Prospects
    nutrients Review African Sorghum-Based Fermented Foods: Past, Current and Future Prospects Oluwafemi Ayodeji Adebo Department of Biotechnology and Food Technology, Faculty of Science, University of Johannesburg (Doornfontein Campus), P.O. Box 17011 Johannesburg, Gauteng 2028, South Africa; [email protected]; Tel.: +27-11-559-6261 Received: 28 February 2020; Accepted: 14 April 2020; Published: 16 April 2020 Abstract: Sorghum (Sorghum bicolor) is a well-known drought and climate resistant crop with vast food use for the inhabitants of Africa and other developing countries. The importance of this crop is well reflected in its embedded benefits and use as a staple food, with fermentation playing a significant role in transforming this crop into an edible form. Although the majority of these fermented food products evolve from ethnic groups and rural communities, industrialization and the application of improved food processing techniques have led to the commercial success and viability of derived products. While some of these sorghum-based fermented food products still continue to bask in this success, much more still needs to be done to further explore evolving techniques, technologies and processes. The addition of other affordable nutrient sources in sorghum-based fermented foods is equally important, as this will effectively augment the intake of a nutritionally balanced product. Keywords: sorghum; fermentation; lactic acid bacteria; fermented products; food security; 4th industrial revolution (4IR) 1. Introduction In terms of production quantity, sorghum is the fifth most important cereal crop in the world after rice, wheat, maize and barley, and the most grown cereal in Sub-Saharan Africa, after maize [1–3].

This library was established from 12 different ligations using high-molecular-weight DNA generated from either one cycle or two cycles of size selection. This library consists of 38 016 BAC clones with an estimated average insert size of 126 kb and coverage of 6.6 genome equivalents. The 6.6 genome-equivalent BAC library of S. propinquum provides a 99.7% probability of finding one or more BACs that contain genes of interest. Twenty mapped DNA probes, ten homologous and ten heterologous, were used to screen the library, and 121 positive clones were identified, 6.05 per locus or 6.37 per probe.

  • GENETIC ANALYSIS of PLANT ARCHITECTURE in SORGHUM by WENQIAN KONG (Under the Direction of Andrew H. Paterson) ABSTRACT Plant
    GENETIC ANALYSIS OF PLANT ARCHITECTURE IN SORGHUM by WENQIAN KONG (Under the Direction of Andrew H. Paterson) ABSTRACT Plant architecture is the three-dimensional organization of the plant body. Above- ground architecture is determined by the size, shape and positions of leaves, stems and flowers; and underground architecture by roots and rhizomes. We conduct quantitative trait locus (QTL) mapping in a recombinant inbred line (RIL) population derived from two morphologically distinct parents, S. bicolor and S. propinquum , to identify genomic regions responsible for vegetative branching pattern and rhizomatousness, respectively, and to facilitate comparisons between these two traits and among their respective components. We show overlapping genetic control of above-ground and below-ground plant architecture, validate quantitative trait loci (QTLs) previously reported in an F2 population of the same cross, and discover additional QTLs. Understanding the genetic determinants of plant architecture sheds new light on genetic manipulation of plants for a variety of purposes, and advances progress towards identification of underlying genes that may contribute to plant growth regulation.

Since their discovery, Bs have been subjected to countless studies aiming at the clarification of their origin, composition, and influence on the carriers. Despite these efforts, we still have very limited knowledge of the processes that led to the emergence of Bs, the mechanisms of their transmission, and the effects of Bs on the hosts. In the last decade, sophisticated molecular methods, including next-generation sequencing, have provided powerful tool to help answer some of these questions, but not many species have received much attention yet. In this review, we summarize the currently available information about Bs in the genus Sorghum, which has so far been on the periphery of scientific interest. We present an overview of the occurrence and characteristics of Bs in various Sorghum species, discuss the possible mechanisms involved in their maintenance and elimination, and outline hypotheses of the origin of Bs in this genus.

Perennial grain sorghum plants produce subterranean stems known as rhizomes that sprout to form the next season’s crop. In Kansas, breeding perennial sorghum involves crossing S. bicolor cultivars or breeding lines to S. halepense or perennial n S. bicolor × S. halepense breeding lines, selecting perennial plants from F2 or subsequent populations, crossing those plants with S. bicolor, and repeating the cycle. A retrospective field trial in Kansas showed that selection and backcrossing during 2002–2009 had improved grain yields and seed weights of breeding lines. Second-season grain yields of sorghum lines regrowing from rhizomes were similar to yields in the first season. Further selection cycles have been completed since 2009. Many rhizomatous lines that cannot survive winters in Kansas are perennial at subtropical or tropical locations in North America and Africa.
