Modeling and mapping QTL for senescence-related traits in winter wheat under high temperature (2010, background): “The Gpc-B1 gene has been cloned and found to have multiple pleiotropic effects on grain protein content, progression of leaf senescence, remobilization of nutrients, and grain development (Uauy et al. 2006).”
Mineral element concentrations in grains of Chinese wheat cultivars (2010, result): “In agreement with this result, Distelfeld et al. (2004) and Uauy et al. (2006) has showed that a locus on the short arm of chromosome 6B (Gpc-B1) in wheat was effective in increasing the accumulation of protein content, Fe, and Zn in grain, due to an increased remobilization of nutrients from…”
Iron uptake, translocation, and regulation in higher plants. (2012, background): “(134) reported that an NAC transcription factor gene, NO APICAL MERISTEM B1 (NAM-B1), in wheat accelerates senescence and increases the remobilization of Fe and Zn from leaves to developing grains.”
Iron and zinc biofortification strategies in dicot plants by intercropping with gramineous species. A review (2011, background): “Recently, a NAC gene was identified in wheat, which can accelerate senescence and increase Zn and Fe remobilization from leaves to developing grains (Uauy et al., 2006).”
Breeding for increased nitrogen‐use efficiency: a review for wheat (T. aestivum L.) (2016, background): “A transcription factor (NAM-B1) accelerates senescence and increases N remobilization from leaves to grains in wheat (Uauy et al. 2006).”
A Bioinformatic Analysis of NAC Genes for Plant Cell Wall Development in Relation to Lignocellulosic Bioenergy Production (2009, background): “Downregulation of NAM-B1 in wheat delays senescence by more than 21 days [7] and reduces wheat grain protein, zinc, and iron content by more than 30%, possibly via defects in nutrient remobilization from leaves to grains.”
Relationship between yield and mineral nutrient concentrations in historical and modern spring wheat cultivars (2008, background): “This corresponds with recent Wndings by Uauy et al. (2006) that show both Fe and Zn content are inXuenced by the high protein gene Gpc-B1.”
Identification of quantitative trait locus of zinc and phosphorus density in wheat (Triticum aestivum L.) grain (2008, background): “One gene has been found affecting N, Fe and Zn content at the same time (Uauy et al. 2006).”
Managing the Nutrition of Plants and People (2012, positive): “In wheat, the expression of a functional NAC transcription factor (NAM-B1) increases grain Fe and Zn concentrations by accelerating senescence and increasing the remobilisation of these elements from leaves to developing grain [170].”
Cultivated einkorn wheat (Triticum monococcum L. subsp. monococcum): the long life of a founder crop of agriculture (2014, background): “2006) and a member of the senescence and nutrient remobilisation controlling NAC gene family (Uauy et al. 2006).”
Introgression of a major gene for high grain protein content in some Indian bread wheat cultivars (2011, methodology): “This was followed by positional cloning of Gpc-B1, thus facilitating the development of even “perfect” markers for this gene (Uauy et al., 2006).”
Effects of the Chromosome Region Including the Gpc‐B1 Locus on Wheat Grain and Protein Yield (2010, background): “…associated with a signifi cant increase in residual N in the fl ag leaves of the transgenic plants compared with the nontransgenic sister lines (Uauy et al., 2006b), which also supports the hypothesis of a more effi cient N remobilization in plants with higher transcript levels of the…”
