“…Rice grains contain 10 mg/100 g of calcium, whereas some genotypes of finger millet contain relatively high amounts of calcium in their seeds (376-515 mg/100 g), which is far above levels seen in other cereals and millets (Barbeau and Hilu, 1993;Panwar et al, 2010). Though calcium is important for maintaining human health, few research efforts have been directed toward understanding the mechanisms of calcium accumulation in developing cereal grains.…”

The calcium (Ca 2+ ) transporters, like Ca 2+ channels, Ca 2+ ATPases, and Ca 2+ exchangers, are instrumental for signaling and transport. However, the mechanism by which they orchestrate the accumulation of Ca 2+ in grain filling has not yet been investigated. Hence the present study was designed to identify the potential calcium transporter genes that may be responsible for the spatial accumulation of calcium during grain filling. In silico expression analyses were performed to identify Ca 2+ transporters that predominantly express during the different developmental stages of Oryza sativa. A total of 13 unique calcium transporters (7 from massively parallel signature sequencing [MPSS] data analysis, and 9 from microarray analysis) were identified. Analysis of variance (ANOVA) revealed differential expression of the transporters across tissues, and principal component analysis (PCA) exhibited their seed-specific distinctive expression profile. Interestingly, Ca 2+ exchanger genes are highly expressed in the initial stages, whereas some Ca 2+ ATPase genes are highly expressed throughout seed development. Furthermore, analysis of the cis-elements located in the promoter region of the subset of 13 genes suggested that Dof proteins play essential roles in regulating the expression of Ca 2+ transporter genes during rice seed development. Based on these results, we developed a hypothetical model explaining the transport and tissue specific distribution of calcium in developing cereal seeds. The model may be extrapolated to understand the mechanism behind the exceptionally high level of calcium accumulation seen in grains like finger millet.

“…Alternatively, they may be harvestable during seasons when other foods are scarce (Johns, 1994). Finger millet (Eleusine coracana), for example, suffers relatively few diseases and pests, is tolerant to soil moisture stress and has excellent storage qualities ( Barbeau and Hilu, 1993). It also has a growth cycle of only three months and thus can provide two harvests a year.…”

“…For example, finger millet has been found to be a good nutrient source with relatively high calcium content ( Barbeau and Hilu, 1993 (Akhtar, 1987). It has also been found that an increased incidence of chronic diseases, such as diabetes, is experienced by many indigenous people as they adopt western diets and lifestyles.…”

(ABSTRACT)Nymphaea petersiana Klotzsch (Nyika) is an important wild tuber eaten in some districts of Malawi. The tubers were processed by boiling/freeze-drying(BFD) and sundrying(USD).The tuber's nutrient and antinutrient composition was determined to produce a preliminary nutrient data base for use in sub-Saharan Africa.There was no significant difference (P > 0.05) in protein content of BFDand USD samples. Sun-dried samples were significantly (P < .05) higher in ash than boiled samples while boiled samples were significantly higher (P < .05) in crude fat and total carbohydrate. The protein content of the tubers (8.0 and 8.1 %) was higher than that of the staple maize (7.9%), African millets (unspecified) (7.5%), and polished rice (7.0%), but lower than sorghum (10.7%). Protein content was higher than tubers like cassava (1.3%), potato (2%), sweet potato (1.6%), yams (1.5%) and N. lotus (5.2). Nyika tubers have a well balanced amino acid content, limiting only in lysine.There were no significant (P > 0.05) differences in the mineral content of BFD and USD samples, except for iron, which was lower in the boiled samples. Nyika tubers have a higher calcium (1376 and 946 g/g) and phosphorus (2250 and 2883 g/g ) content than wild and domesticated cassava, potatoes, sweet potatoes and wild and domesticated yams. Sun-dried tubers have a higher iron content (88g/g) than maize (20g/g). The zinc content of tuber was higher (21and 25 g/g) than that of boiled maize flour, boiled sorghum flour, rice, cassava, and sweet potato. The predominant fatty acids in the tubers were oleic (47%), linoleic (32%), palmitic (21%) and linolenic (7%) acids.Ascorbic acid content was very low, only 0.1 and 0.003 mg/100g.Tannin content was lower (1 and 1.7 %) in the tubers than in Vulgare Pers. sorghum, DeKalb sorghum from U.S. and Kabale sorghum from Uganda. There was a significantly (P < 0.05) lower content of phytate in boiled (3.9 g/g) than in sun-dried tubers (6.0 g/g). Phytate content of the tubers was lower than that of cooked maize flour, unrefined maize flour, cassava and sweet potato. Trypsin inhibitor activity in the tubers was reduced from 463 to 55 TIU/g tuber and chymotrypsin inhibitor activity was reduced to 50 from 267 CIU/g tuber by cooking.Nyika is a good source of iron and quality protein limiting only in lysine. Protein is comparable to staple maize and higher than root crops consumed in Malawi. It is not a good source of fat and ascorbic acid. Tannin, phytate, trypsin, and chymotrypsin inhibitor content lower than most food crops consumed in Malawi. Grant Information

“…The world's largest contribution to selections was in countries where common millet is most grown, such as India and USA (Manoharan & Sivasubramanian 1982, Baltensperger 2002, Karam et al 2004, Upadhyaya et al 2011. Crossing of various genotypes and examination of a large number of qualitative and quantitative indicators has been the subject of many studies (Barbeau & Hilu 1993, Zeller 2000, Heyduck et al 2008, Cho et al 2010, Hunt et al 2011. The aim of this study was to determine millet genotypes productivity for grain, based on regular and stubble crop on yield and individual agro-biological traits.…”

Summary: Agro-biological traits of common millet (Panicum miliaceum L.) genotypes were studied on experimental lots of the Institute of Field and Vegetable Crops in Bački Petrovac, Serbia in 2009 and 2010. The study included 16 genotypes of millet grown and used in selection programs in Serbia and abroad. Crops in trials were based on regular and stubble crops. A significant variability appeared during and at the end of growing season in the number of days from emergence to earing of some genotypes of millet, plant height, grain yield, 1000-grain weight and test weight of the test material, and it can be used as a good basis for further work on breeding and improvement of common millet. Cluster analysis identified genotypes with high performance for yield per plant, but also good stability of other studied parameters. Studies have shown that the genetic factor had significant effect on realized values of all tested traits. The difference between the yield of millet in regular and stubble crops was also statistically significant. Out of 9 varieties and lines of millet, 3 of them achieved a higher yield in stubble crops. From the point of agro-biological traits, 2010 was more favourable for the production of millet.
