A novel Brassica–rhizotron system to unravel the dynamic changes in root system architecture of oilseed rape under phosphorus deficiency (2016)
Journal Article

Background and Aims: An important adaptation of plants to phosphorus (P) deficiency is to alter root system architecture (RSA) to increase P acquisition from the soil, but soil-based observations of RSA are technically challenging, especially in matu...

High-throughput phenotyping (HTP) identifies seedling root traits linked to variation in seed yield and nutrient capture in field-grown oilseed rape (Brassica napus L.) (2016)
Journal Article

Background and Aims. Root traits can be selected for crop improvement. Techniques such as soil excavations can be used to screen root traits in the field, but are limited to genotypes that are well-adapted to field conditions. The aim of this study w...

Inter-cultivar variation in soil-to-plant transfer of radiocaesium and radiostrontium in Brassica oleracea (2016)
Journal Article

Radiocaesium and radiostrontium enter the human food chain primarily via soil-plant transfer. However, uptake of these radionuclides can differ significantly within species (between cultivars). The aim of this study was to assess inter-cultivar varia... Read More about Inter-cultivar variation in soil-to-plant transfer of radiocaesium and radiostrontium in Brassica oleracea.

Analysis of root growth from a phenotyping data set using a density-based model (2016)
Journal Article

Major research efforts are targeting the improved performance of root systems for more efficient use of water and nutrients by crops. However, characterizing root system architecture (RSA) is challenging, because roots are difficult objects to observ...

Dietary mineral supplies in Malawi: spatial and socioeconomic assessment (2015)
Journal Article

© 2015 Joy et al. Background: Dietary mineral deficiencies are widespread globally causing a large disease burden. However, estimates of deficiency prevalence are often only available at national scales or for small population sub-groups with limited...

Global magnesium supply in the food chain (2015)
Journal Article

© CSIRO 2015. Magnesium (Mg) is an essential mineral micronutrient in humans. Risks of dietary Mg deficiency are affected by the quantity of Mg ingested and its bioavailability, which is influenced by the consumption of other nutrients and 'anti-nutr...

Dietary calcium and zinc deficiency risks are decreasing but remain prevalent (2015)
Journal Article

Globally, more than 800 million people are undernourished while >2 billion people have one or more chronic micronutrient deficiencies (MNDs). More than 6% of global mortality and morbidity burdens are associated with undernourishment and MNDs. Here w...

Zinc-enriched fertilisers as a potential public health intervention in Africa (2015)
Journal Article

Background In this review, we examine the potential of Zn-enriched fertilisers to alleviate human dietary Zn deficiency. The focus is on ten African countries where dietary Zn supply is low and where fertiliser subsidies are routinely deployed on...

Journal Article

Inter-varietal variation in caesium and strontium uptake by plants: a meta-analysis (2014)
Journal Article

Radiocaesium and radiostrontium enter the foodchain primarily via plant root uptake. Selecting varieties of crop that display low accumulation of these radionuclides has been suggested as an economically and socially acceptable remediation strategy f...

Soil type influences crop mineral composition in Malawi (2014)
Journal Article

© 2014. Food supply and composition data can be combined to estimate micronutrient intakes and deficiency risks among populations. These estimates can be improved by using local crop composition data that can capture environmental influences includin... Read More about Soil type influences crop mineral composition in Malawi.

Genetical and comparative genomics of Brassica under altered Ca supply identifies Arabidopsis Ca-transporter orthologs (2014)
Journal Article

Although Ca transport in plants is highly complex, the overexpression of vacuolar Ca2+ transporters in crops is a promising new technology to improve dietary Ca supplies through biofortification. Here, we sought to identify novel targets for increasi... Read More about Genetical and comparative genomics of Brassica under altered Ca supply identifies Arabidopsis Ca-transporter orthologs.

Dietary mineral supplies in Africa (2014)
Journal Article

Dietary micronutrient deficiencies (MNDs) are widespread, yet their prevalence can be difficult to assess. Here, we estimate MND risks due to inadequate intakes for seven minerals in Africa using food supply and composition data, and consider the pot... Read More about Dietary mineral supplies in Africa.

A scanner system for high-resolution quantification of variation in root growth dynamics of Brassica (2014)
Journal Article

The potential exists to breed for root system architectures that optimize resource acquisition. However, this requires the ability to screen root system development quantitatively, with high resolution, in as natural an environment as possible, with...

Soil-type influences human selenium status and underlies widespread selenium deficiency risks in Malawi (2013)
Journal Article

Selenium (Se) is an essential human micronutrient with critical roles in immune functioning and antioxidant defence. Estimates of dietary Se intakes and status are scarce for Africa although crop surveys indicate deficiency is probably widespread in...

Analysis of ripening-related gene expression in papaya using an Arabidopsis-based microarray (2012)
Journal Article

Background Papaya (Carica papaya L.) is a commercially important crop that produces climacteric fruits with a soft and sweet pulp that contain a wide range of health promoting phytochemicals. Despite its importance, little is known about transcrip... Read More about Analysis of ripening-related gene expression in papaya using an Arabidopsis-based microarray.

Maize grain and soil surveys reveal suboptimal dietary selenium intake is widespread in Malawi (2011)
Journal Article

Selenium is an essential element in human diets but the risk of suboptimal intake increases where food choices are narrow. Here we show that suboptimal dietary intake (i.e. 20–30 mg Se person21 d21) is widespread in Malawi, based on a spatial integra...
