Zinc (Zn) is an essential micronutrient for plants, playing catalytic or structural roles in enzymes, transcription factors, ribosomes and membranes. In humans, Zn deficiency the second most common mineral nutritional disorder, affecting around 30% of world's population. People living poverty usually have their diets based on milled cereals, which contain low concentrations. Biofortification crops attractive cost-effective solution dietary intake. order to increase amounts bioavailable crop...
Abstract Rice is a staple food for half of the human population. Unlike other cereals such as wheat and barley, rice plants are susceptible to cold stress, which often results in decreased productivity, especially regions where indica subspecies cultivated. Low temperatures can have negative impacts on during germination, vegetative growth, reproductive stages. Considering expected higher frequency extreme temperature events near future, waves could even increase low production. Here, we...
Iron (Fe) is an essential micronutrient that frequently inaccessible to plants. Rice (Oryza sativa L.) plants employ the Combined Strategy for Fe uptake, which composed by all features of II, common Poaceae species, and some I, non-Poaceae species. To understand evolution uptake mechanisms, we analyzed root transcriptomic response deficiency in O. its wild progenitor rufipogon. We identified 622 2,017 differentially expressed genes rufipogon, respectively. Among up-regulated both found...
Abstract Background Eucalyptus globulus and its hybrids are very important for the cellulose paper industry mainly due to their low lignin content frost resistance. However, rooting of cuttings this species is recalcitrant exogenous auxin application often necessary good root development. To date one most accurate methods available gene expression analysis quantitative reverse transcription-polymerase chain reaction (qPCR); however, reliable use technique requires reference genes...
Oryza sativa, the common cultivated rice, is one of most important crops for human consumption, but production increasingly threatened by abiotic stresses. Although many efforts have resulted in breeding rice cultivars that are relatively tolerant to their local environments, climate changes and population increase expected soon call new, fast generation stress germplasm, current within-species diversity might not be enough overcome such needs. The genus contains other 23 wild species, with...

Copper (Cu) is essential to plants but can also be harmful due Fenton chemistry. Because of that, it necessary keep Cu within a narrow concentration limit. Plants evolved mechanisms sense and precisely regulate uptake accumulation avoid both deficiency toxicity. However, experience variable levels in soils, natural environments as well human’s-based farming practices that lead soils. Therefore, we need understand homeostasis. Here, review how found soils; toxicity responses plants; the role...
Abstract Background Duplications are very common in the evolution of plant genomes, explaining high number members gene families. New genes born after duplication can undergo pseudogenization, neofunctionalization or subfunctionalization. Rice is a model for functional genomics research, an important crop human nutrition and target biofortification. Increased zinc iron content rice grain could be achieved by manipulation metal transporters. Here, we describe ZINC-INDUCED FACILITATOR-LIKE...

Abstract Background Minimal information exists on whole-plant dynamics of mineral flow through rice plants and the source tissues responsible for export to developing seeds. Understanding these phenomena in a model plant could help development nutritionally enhanced crop cultivars. A accumulation study, using harvests during reproductive under different Fe supplies, was conducted characterize roots, non-flag leaves, flag stems/sheaths, panicles Kitaake plants. Results Low supply promoted...

Iron is an essential nutrient for plants. In aerobic conditions, Fe highly unavailable plant uptake, and deficiency can be severe in plants grown calcareous soils. waterlogged soils, however, availability increases reach toxic concentrations. Rice important staple crop worldwide faces iron or excess, depending on the growth conditions. To contribute to study of mechanisms involved response resistance experiments were carried out with rice cultivars BR-IRGA 409 (I409, susceptible toxicity)...
Senescence is a coordinated process where plant, or part of it, engages in programmed cell death to salvage nutrients by remobilizing them younger tissues developing seeds. As Fe and Zn deficiency are the two major nutritional disorders humans, increased concentration these through biofortification cereal grains long-sought goal. Recent evidences point link between onset leaf senescence remobilization. In wheat, one member NAC transcription factor family (NAM-B1) has role process, probably...

Flag leaves play an important role in synthesis and translocation of photoassimilates the rice plant, affecting grain yield; similarly they were believed to be a major source remobilized minerals for seeds. At same time, seed's sink strength plays dry matter accumulation. To investigate relative contribution flag seed mineral accumulation, field experiments conducted evaluate effect leaf or half-seed removal on Fe, Mn Zn concentration content. 50% seeds removed at anthesis. Seed accumulation...
