Fertilizer management and soil type influence grain zinc and iron concentration under contrasting smallholder cropping systems in Zimbabwe (2019)
Journal Article

Micronutrient defciencies remain prevalent in food systems of southern Africa, although advances in biofortifcation through crop breeding and agronomy provide opportunities to address these. We determined baseline soil availability of zinc (Zn) and i...

Linear relationships between shoot magnesium and calcium concentrations among angiosperm species are associated with cell wall chemistry (2018)
Journal Article

Background Linear relationships are commonly observed between shoot magnesium ([Mg]shoot) and shoot calcium ([Ca]shoot) concentrations among angiosperm species growing in the same environment. Scope and Conclusions This article argues that, in p...

Identification and expression profiling of Pht1 phosphate transporters in wheat in controlled environments and in the field (2017)
Journal Article

Phosphorus (P) is an important macronutrient with critical functions in plants. Phosphate (Pi) transporters which mediate Pi acquisition and Pi translocation within the plant are key factors in Pi deficiency responses. However, their relevance for ad...

Validation of an updated Associative Transcriptomics platform for the polyploid crop species Brassica napus by dissection of the genetic architecture of erucic acid and tocopherol isoform variation in seeds (2017)
Journal Article

An updated platform was developed to underpin association genetics studies in the polyploid crop species Brassica napus (oilseed rape). Based on 1.92 × 1012 bases of leaf mRNAseq data, functional genotypes, comprising 355 536 single-nucleotide polymo...

Identification of candidate genes for calcium and magnesium accumulation in Brassica napus L. by association genetics (2017)
Journal Article

Calcium (Ca) and magnesium (Mg) are essential plant nutrients and vital for human and animal nutrition. Biofortification of crops has previously been suggested to alleviate widespread human Ca and Mg deficiencies. In this study, new candidate genes i...

A scanner-based rhizobox system enabling the quantification of root system development and response of Brassica rapa seedlings to external P availability (2017)
Journal Article

Rhizoboxes are soil-root compartments that may well provide the closest naturalistic conditions for studying root systems architectures (RSAs) in controlled environments. Rhizobox-based studies can however lead to mis-estimation of root traits due to... Read More about A scanner-based rhizobox system enabling the quantification of root system development and response of Brassica rapa seedlings to external P availability.

Breeding histories and selection criteria for oilseed rape in Europe and China identified by genome wide pedigree dissection (2017)
Journal Article

Selection breeding has played a key role in the improvement of seed yield and quality in oilseed rape (Brassica napus L.). We genotyped Tapidor (European), Ningyou7 (Chinese) and their progenitors with the Brassica 60?K Illumina Infinium SNP array an...

Genetic variants associated with the root system architecture of oilseed rape (Brassica napus L.) under contrasting phosphate supply (2017)
Journal Article

Breeding crops with ideal root system architecture for efficient absorption of phosphorus is an important strategy to reduce the use of phosphate fertilizers. To investigate genetic variants leading to changes in root system architecture, 405 oilseed... Read More about Genetic variants associated with the root system architecture of oilseed rape (Brassica napus L.) under contrasting phosphate supply.

Variation in tuber mineral concentrations among accessions of Solanum species held in the Commonwealth Potato Collection (2017)
Journal Article

The variation in tuber mineral concentrations amongst accessions of wild tuber-bearing Solanum species in the Commonwealth Potato Collection (CPC) was evaluated under greenhouse conditions. Selected CPC accessions, representing the eco-geographical d...

Evolutionary origins of abnormally large shoot sodium accumulation in nonsaline environments within the Caryophyllales (2016)
Journal Article

The prevalence of sodium (Na) “hyperaccumulator” species, which exhibit abnormally large shoot sodium concentrations ([Na]shoot) when grown in non-saline environments, was investigated among angiosperms in general and within the Caryophyllales order... Read More about Evolutionary origins of abnormally large shoot sodium accumulation in nonsaline environments within the Caryophyllales.

Root morphology and seed and leaf ionomic traits in a Brassica napus L. diversity panel show wide phenotypic variation and are characteristic of crop habit (2016)
Journal Article

Background Mineral nutrient uptake and utilisation by plants are controlled by many traits relating to root morphology, ion transport, sequestration and translocation. The aims of this study were to determine the phenotypic diversity in root morph...

QTL meta-analysis of root traits in Brassica napus under contrasting phosphorus supply in two growth systems (2016)
Journal Article

© The Author(s) 2016. A high-density SNP-based genetic linkage map was constructed and integrated with a previous map in the Tapidor x Ningyou7 (TNDH) Brassica napus population, giving a new map with a total of 2041 molecular markers and an average m...

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...
