Genetic variation and environmental stability of grain mineral nutrient concentrations in Triticum dicoccoides under five environments (2009, unknown): “dicoccoides, and known to affect Zn and Fe concentrations in the grain (Distelfeld et al. 2007).”
Zinc biofortification in rice: leveraging agriculture to moderate hidden hunger in developing countries (2018, background): “Locus Gpc-B1, influencing both Zn and protein concentrations, located on the short arm of chromosome 6B, had been studied with various recombinant substitution lines derived from Triticum dicoccoide (Distelfeld et al. 2007).”
Wheat Landraces: A mini review - (2013, background): “the wheat plant, thus enhancing the uptake of phosphorus, in particular, and other macro- and micro-nutrients, in general (Distefeld et al., 2007; Koshgoftarmanesh et al., 2010).”
Biofortification strategies to increase grain zinc and iron concentrations in wheat (2014, unknown): “The TtNAM-B1 gene, originated from T. dicoccoides, affecting grain protein, Zn, and Fe has been cloned (Distelfeld et al., 2007).”
Mechanism of Zinc absorption in plants: uptake, transport, translocation and accumulation (2016, background): “Later on, studies with recombinant substitutions lines mapped a quantitative trait loci, GPC-B1 (GRAIN PROTEIN CONTENT B1) in chromosome 6B which was associated with increased contents of Fe, and Zn along with higher levels of grain protein, content (Fahima et al. 2006; Distelfeld et al. 2007).”
Grain zinc, iron and protein concentrations and zinc-efficiency in wild emmer wheat under contrasting irrigation regimes (2008, background): “Increasing number of reports is available showing that wild and primitive wheat species generally contain more Zn than Fe in seeds, as reported by Monasterio and Graham (2000), Cakmak et al. (2004), Bonfil and Kafkafi (2000) and Distelfeld et al (2007).”
Enrichment of cereal grains with zinc: Agronomic or genetic biofortification? (2007, background): “The enhancing role of Gpc-B1 on grain Zn and protein concentrations has been shown consistently in five different environments, suggesting that the effect of GxE on the Zn and protein levels of the lines carrying the Gpc-B1 allele is small (Distelfeld et al. 2007).”
Quantitative trait loci analysis of zinc efficiency and grain zinc concentration in wheat using whole genome average interval mapping (2008, background): “Despite this the change in grain Zn associated with these QTL is of a similar magnitude, both in relative and absolute terms, to that reported for the high protein Gpc-B1 locus among recombinant substitution lines grown under much more favourable conditions (Fahima et al. 2006; Distelfeld et al. 200”

Biofortification of crops with seven mineral elements often lacking in human diets--iron, zinc, copper, calcium, magnesium, selenium and iodine. (2009, background): “aestivum) and durum (Triticum durum) wheat (Bänziger & Long, 2000; Monasterio & Graham, 2000, Garvin et al., 2006; Oury et al., 2006; Distelfeld et al., 2007; OrtizMonasterio et al., 2007; McDonald et al., 2008), although the strength of these relationship is influenced greatly by the environment.”
Breeding for increased grain protein and micronutrient content in wheat: Ten years of the GPC-B1 gene (2017, background): “Langdon recombinant substitution lines carrying chromosome 6B from DIC exhibited increased Mn grain content of 10.9 mg kg 1 compared to the control (Distelfeld et al., 2007) while the hexaploid cultivar Scarlet, which carries the functional GPC-B1 allele showed increased Ca grain concentration of…”
Wild emmer: genetic resources, gene mapping and potential for wheat improvement (2008, background): “…Gpc-B1 is a NAC transcription factor determining increased zinc and iron contents as well as grain protein, the introgressed T. dicoccoides segment in cultivated wheats will improve multiple traits (Uauy et al. 2006a, b; Distelfeld et al. 2007; http://maswheat.ucdavis.edu/Germplasms/index.html).”
Managing the Nutrition of Plants and People (2012, unknown): “In addition to these agronomic strategies, varieties of rice are being identified that accumulate lower concentrations of As, and other potentially toxic elements, in grain and QTL associated with these traits are being identified for breeding safer crops [137, 194, 195].”
