The holistic rhizosphere: integrating zones, processes, and semantics in the soil influenced by roots (2016)
Journal Article

Despite often being conceptualized as a thin layer of soil around roots, the rhizosphere is actually a dynamic system of interacting processes. Hiltner originally defined the rhizosphere as the soil influenced by plant roots. However, soil physicists...

Multi-omics analysis identifies genes mediating the extension of cell walls in the Arabidopsis thaliana root elongation zone (2015)
Journal Article

Plant cell wall composition is important for regulating growth rates, especially in roots. However, neither analyses of cell wall composition nor transcriptomes on their own can comprehensively reveal which genes and processes are mediating growth an...

A fluorescent hormone biosensor reveals the dynamics of jasmonate signalling in plants (2015)
Journal Article

Activated forms of jasmonic acid (JA) are central signals coordinating plant responses to stresses, yet tools to analyse their spatial and temporal distribution are lacking. Here we describe a JA perception biosensor termed Jas9-VENUS that allows the... Read More about A fluorescent hormone biosensor reveals the dynamics of jasmonate signalling in plants.

Plant embryogenesis requires AUX/LAX-mediated auxin influx (2015)
Journal Article

The plant hormone auxin and its directional transport are known to play a crucial role in defining the embryonic axis and subsequent development of the body plan. Although the role of PIN auxin efflux transporters has been clearly assigned during emb... Read More about Plant embryogenesis requires AUX/LAX-mediated auxin influx.

Phenotyping pipeline reveals major seedling root growth QTL in hexaploid wheat (2015)
Journal Article

Seedling root traits of wheat (Triticum aestivum L.) have been shown to be important for efficient establishment and linked to mature plant traits such as height and yield. A root phenotyping pipeline, consisting of a germination paper-based screen c... Read More about Phenotyping pipeline reveals major seedling root growth QTL in hexaploid wheat.

Inference of the Arabidopsis lateral root gene regulatory network suggests a bifurcation mechanism that defines primordia flanking and central zones (2015)
Journal Article

A large number of genes involved in lateral root (LR) organogenesis have been identified over the last decade using forward and reverse genetic approaches in Arabidopsis thaliana. Nevertheless, how these genes interact to form a LR regulatory network...

Auxin influx importers modulate serration along the leaf margin (2015)
Journal Article

Leaf shape in Arabidopsis is modulated by patterning events in the margin that utilize a PIN‐based auxin exporter/CUC2 transcription factor system to define regions of promotion and retardation of growth, leading to morphogenesis. In addition to auxi... Read More about Auxin influx importers modulate serration along the leaf margin.

On the evaluation of methods for the recovery of plant root systems from X-ray computed tomography images (2014)
Journal Article

© CSIRO 2015. X-ray microcomputed tomography (μCT) allows nondestructive visualisation of plant root systems within their soil environment and thus offers an alternative to the commonly used destructive methodologies for the examination of plant root...
