Root growth and plant height connected to an auxin-related gene
What makes a plant tall? Scientists think it may be connected to a gene involved in responding to the hormone Auxin.
WALTer: A 3D wheat model that simulates tillering dynamics
Branching is a main morphogenetic process involved in the adaptation of plants to the environment. In grasses, tillering is divided into three phases: tiller emergence, cessation of tillering and tiller regression...

Genome-wide association study reveals genomic regions controlling root and shoot traits at late growth stages in wheat
How much wheat do we need? One prediction is we need production to double between 2005 and 2050. This challenge is more difficult due to abiotic stress with climate change. Long Li and colleagues have been examining...
FSPM-based investigation of plant interactions in complex wheat canopies
Functional–structural plant models (FSPMs) explicitly describe individual plant architecture, making this approach suitable for unravelling plant–plant interactions in complex canopies. Barillot et al. developed a...
Splash dispersal and disease resistance in mixtures of cultivars with contrasting height
Cultivar mixtures have an important role to play in reducing the propagation of diseases, as is evident from the well-documented results of growing mixtures of cultivars from plants that exhibit different levels of...

Maize nutrient uptake and photosynthesis in intercropping
Maize and wheat are globally important food crops. The two species can be grown as an intercrop, with substantial land sparing in the order of 20%, as expressed by a land equivalent ratio of approximately 1.2. In a...

Introgression of Aegilops speltoides in a hexaploid wheat background
Aegilops. speltoides introgressions have the potential to play a critical role in the development of superior wheat varieties in the future.
Deep rooting in a wheat doubled haploid population with wild emmer introgression
This is the first study to identify QTLs for rooting at depth in field-grown wheat at mature growth stages.
Mapping wheat genes for root hair length in aneuploid lines of bread wheat
Long root hairs enable the efficient uptake of poorly mobile nutrients such as phosphorus. Mapping the chromosomal locations of genes that control root hair length can help exploit the natural variation within crops to...
Seedling root architectural traits associated with yield in wheat
Roots, the ‘hidden half’ of plants, are notoriously difficult to phenotype. Xie et al. utilise a ‘pouch and wick’ high-throughput phenotyping pipeline to quantify the variation in seedling root system architecture of...
C4 Wheat? Lend an ear to hear more
One of the Grand Challenges – and, arguably, the Holy Grail – of plant research at present is an attempt to improve the photosynthetic efficiency of plants. Somewhat surprisingly, the fundamental photosynthetic pathway...

Simulating carbon and nitrogen patterns using an integrated model of wheat functioning
Based on a mechanistic approach, the CN-Wheat model simulates the fluxes of carbon (C) and nitrogen (N) metabolites in wheat plants after anthesis. Barillot et al. show that the CN-Wheat model can be used to predict...
A process-based model of C and N metabolism in the wheat culm
Linking traits and metabolic processes to whole plant performance results in improved crops. Barillot et al., present CN-Wheat, a comprehensive and mechanistic model of carbon (C) and nitrogen (N) metabolism within...
