structure of sorghum

Sorghum is produced in over 100 countries, but of these, only 14 produce about a million tonnes or more annually (mt pa) (Table 1). Genotypes with high phosphorus, potash, and polyphenol content are less preferred by P. maidis (Mote and Shahane, 1994). However, due to its lower fat content, sorghum usually has a slightly lower gross, digestible, and metabolizable energy. Sorghum showed highest amylase activities at 96 h germination. The sorghum caryopsis is composed of three anatomical parts: pericarp, endosperm, and germ (Fig. In their descriptions, the sorghum kernel is considered to be a naked caryopsis, which varies widely in size and shape among the sorghum types. drummondii grouped mainly with bicolor race sorghums based on genetic markers (Casa et al., 2005). India is still a major sorghum producer, but there has been a decline of production since 1995, due to a number of changing factors including the increased capacity to irrigate higher value crops such as rice, and the cost and availability of labor for sorghum production. Grain sorghum is a grass similar to corn in vegetative appearance, but sorghum has more tillers and more finely branched roots than corn. Sorghum, in its typical form of consumption, is not a source of vitamin C (Dendy, 1994b). The diploid genome (~730 Mb) has a haploid chromosome number of 10. Artificial crossing between sorghum and Johnsongrass has been carried out to create useful germplasm. Mass-screening technique which involves screening at the seedling stage was developed for greenbug resistance (Huang, 2007). This includes one or two spike lets bisexual flowers. Panicles of S. halepense are more attractive to the females than those of Sorghum stipoideum, Sorghum brachypodum, S. angustum, Sorghum macrospermum, Sorghum nitidium, Sorghum laxiflorum, and S. amplum. The present study aimed to investigate the composition and structure of sorghum spent grains (SSG) as a pre‐requisite for evaluating potential applications of this brewery co‐product. Incubating M. hapla eggs in Sudangrass extract resulted in a 55% reduction in the number of juveniles (J2) penetrating lettuce roots, but juveniles exposed to the extracts were not affected (Widmer and Abawi, 2000). There are at least 150 insect species that can infest sorghum worldwide. Sorghum is an ancient cereal grain belonging to the grass family Poaceae. They were multiplied at the farms of National Research Centre for Sorghum, Rajendranagar, Hyderabad. Kernels of sorghum and millets show considerable diversity in colour, shape, size and certain anatomical components (Table 2). The tryptophan content is higher than that in maize. drummondii (Sahoo et al., 2010), which is an obnoxious weed (shattercane) that closely resembles cultivated sorghum (Defelice, 2006). 1 A). Borer attack can be measured in terms of leaf feeding injury, deadheart formation, and tunneling parameters in stalk and peduncle. A study using simulation to compare climate-adjusted yield improvement found sorghum yield improvement was substantially better than that of wheat in subtropical Australia. They are a source of resistance to Striga ssp. While Americans do use sorghum, India and parts of Africa consider it a particularly valuable food source. Mexico consumes all the sorghum it can produce plus significant imports from the United States. The leaf and stems fibers produced are multicellular and have similar cellulose contents. Elke K. Arendt, Emanuele Zannini, in Cereal Grains for the Food and Beverage Industries, 2013. This has contributed to sorghum production rising to average 2.1 mt pa and yields of 3.1 t ha− 1 over 2004–13. Sorghum endosperm requires a little longer to cook compared to maize endosperm particles. Table 8.5. 149–175. The RCSB PDB also provides a variety of tools and resources. ), head bugs, Calocoris angustatus (Leth. structure in genomic prediction has been extensively studied in major cereal crops, the distinctive evolutionary history and racial structure of sorghum merits the need for investigation into the effect of sorghum racial structure in genomic predic-tion(Guoetal.,2014;Isidroetal.,2015;Normanetal.,2018). Botanical plant structure Sorghum bicolor (L). Screening Techniques for Tnsect Resistance in Sorghum, Table 18.2. Australia is the only non-African country where sorghum production significantly exceeds that of maize. Several priority areas for research are suggested. The hybrid accounts for 3/4 of the total hybrid sorghum seed market (Smith and Frederiksen, 2000). The tryptophan content is higher than that in maize. Sources: Data adapted from Kent and Evens (1994), Gazzaz et al. 2146, 2312, and 18551 of African origin (Table 18.2). The brown sorghums are considered to have 80–85% the feeding value of maize due to the presence of condensed tannins that reduced digestibility. In general, these sources are tall, late maturing, susceptible to lodging, photosensitive, and low yielding. The germ is diploid owing to the sexual union of one male and one female gamete. The United States is the world’s largest producer of sorghum. The Pari community, whose sorghum we explored in-depth, lives in the Lafon villages located around a solitary rocky hilltop on the river Nile’s flood plain in the southeastern part of South Sudan. The opaque-floury endosperm is located around the geometric center of the kernel. The problems of procuring sorghum grain of consistent quality would be resolved by intervention of the agro-based industries in seed multiplication of sorghum and contract farming in suitable agroecological production zones for target products. Taken together, these observations explain how CoA-dependent transferases with similar structural features can participate in different biochemical pathways across species. High-lysine cultivars contain approximately 50% more lysine and promote better weight gains in weaning rats. Concerning protein digestibility, there is strong evidence that wet cooking reduces the protein digestibility of sorghum foods, primarily due to disulfide bond–mediated cross-linking involving the kafirin prolamin proteins. There is also potential for more research to be performed on the other phytochemicals, such as condensed tannins, that contribute to sorghum color and provide potential health benefits. 5.1). The testa, or seed coat, is derived from the ovule integuments; in brown sorghums, it is thick and contains condensed tannins. The principal anatomical components are pericarp, germ or embryo and endosperm. Screening under natural conditions is carried out in such a way that susceptible stage of the crop coincides with peak activity period of the insect. It is prepared by steeping clean whole sorghum grains in water at room temperature for 48–72 h. The fermented grain is washed with clean water and then crushed into a water paste or slurry which is subsequently sieved to remove the bran. The content of total carotenoids was correlated with sorghum pericarp and endosperm pigments. Genotypes with high stem sugar content are reported to be susceptible to stem borer incidence (Bhatt and Singh, 2003). These polyphenols can, however, adversely affect the bioavailability of essential minerals. The Ethiopian increase has been characterized by average yields from 2004 to 2013 of 1.8 t ha− 1 compared to an Africa-wide average of < 1 t ha− 1. The amounts of anthocyanin pigments that darken these grains are less than those from grain with purple or red glumes. McDonough, in Reference Module in Food Science, 2016. Globally, it produces approximately 70 ... Because of to the structure of the flower, mainly sel f-pollination takes place. drummondii and Sorghum purpureosericeum also produced progenies that performed better than the cultivated sorghum parent from a single backcross (Jordan et al., 2011a). Sorghum is a grain crop grown in many parts of the world. The endosperm tissue is triploid, resulting from the fusion of a male gamete with two female polar nuclei. Africa produced 40% of the world's sorghum in the 10 years from 2004 to 2013, and West Africa produced just over half of that. Mixed sorghum contains a blend of kernels with and without pigmented testa. Tissue Culture and Genetic Transformation in Sorghum bicolor, D. Balakrishna, ... B. Venkatesh Bhat, in, Harris, 1961; Teetes, 1985; Franzmann et al., 2006, Franzmann and Hardy, 1996; Sharma and Franzmann, 2001a,b. S. bicolor ssp. D. Balakrishna, ... B. Venkatesh Bhat, in Breeding Sorghum for Diverse End Uses, 2019. Insect damage is one of the challenges that impacts sorghum yields. Hisar in North India is identified as a hot spot for the sorghum stem borer, where severe infestations of this pest occur regularly. Figure 3. To study the impact of sorghum racial structure and diversity in genomic prediction, we … Doggett and other African workers selected types such as Namatera for high tillering recovery resistance. In the cross between sorghum and Johnsongrass reported by Dweikat (2005), progenies were analyzed by genetic markers to confirm that the two genomes behaved normally during meiosis as demonstrated by 1:2:1 segregation ratio of 34 markers. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Birds will consume brown sorghums when other foods are scarce. Species belonging to Heterosorghum (Sorghumlaxiflorum), Parasorghum (Sorghumaustraliense, S. purpureosericeum, S. versicolor, Sorghummatarankense, Sorghumtimorense, Sorghumbrevicallosum, and Sorghumnitidum), and Stiposorghum (Sorghumangustum, Sorghumecarinatum, Sorghumextans, Sorghumintrans, Sorghuminterjectum, and Sorghumstipoideum) showed little damage by the stem borer larvae, C. partellus under artificial infestation in the field (Venkateswaran, 2003). ), sugarcane aphid, Melanaphis sacchari (Zehnt. In India, over the past five decades, a large proportion of the world sorghum germplasm collection has been evaluated for resistance to insect pests, and a number of lines with resistance have been identified (Sharma et al., 1992, 2003). These include Johnson grass (S. halepense), Columbus grass (Sorghum almum), and Sudan grass (Sorghum sudanense).
