Open AccessA quantitative gibberellin signaling biosensor reveals a role for gibberellins in internode specification at the shoot apical meristem
Growth at the shoot apical meristem (SAM) is essential for shoot architecture construction. The phytohormones gibberellins (GA) play a pivotal role in coordinating plant growth, but their role in the SAM remai...

Multi-Knock—a multi-targeted genome-scale CRISPR toolbox to overcome functional redundancy in plants
Plant genomes are characterized by large and complex gene families that often result in similar and partially overlap** functions. This genetic redundancy severely hampers current efforts to uncover novel ph...

Article
What shoots can teach about theories of plant form
Plants generate a large variety of shoot forms with regular geometries. These forms emerge primarily from the activity of a stem cell niche at the shoot tip. Recent efforts have established a theoretical frame...

A network of transcriptional repressors modulates auxin responses
The regulation of signalling capacity, combined with the spatiotemporal distribution of developmental signals themselves, is pivotal in setting developmental responses in both plants and animals1. The hormone aux...

Open AccessWUSCHEL acts as an auxin response rheostat to maintain apical stem cells in Arabidopsis
To maintain the balance between long-term stem cell self-renewal and differentiation, dynamic signals need to be translated into spatially precise and temporally stable gene expression states. In the apical pl...

Open AccessThe Rosa genome provides new insights into the domestication of modern roses
Roses have high cultural and economic importance as ornamental plants and in the perfume industry. We report the rose whole-genome sequencing and assembly and resequencing of major genotypes that contributed t...

Open AccessAuthor Correction: A mechanistic framework for auxin dependent Arabidopsis root hair elongation to low external phosphate
The original version of this Article omitted the following from the Acknowledgements: ‘We also thank DBT-CREST BT/HRD/03/01/2002.’ This has been corrected in both the PDF and HTML versions of the Article.

Open AccessA mechanistic framework for auxin dependent Arabidopsis root hair elongation to low external phosphate
Phosphate (P) is an essential macronutrient for plant growth. Roots employ adaptive mechanisms to forage for P in soil. Root hair elongation is particularly important since P is immobile. Here we report that a...

Open AccessQ&A: How does jasmonate signaling enable plants to adapt and survive?
Jasmonates (JAs) are a class of plant hormones that play essential roles in response to tissue wounding. They act on gene expression to slow down growth and to redirect metabolism towards producing defense mol...

Open AccessModelling the influence of dimerisation sequence dissimilarities on the auxin signalling network
Auxin is a major phytohormone involved in many developmental processes by controlling gene expression through a network of transcriptional regulators. In Arabidopsis thaliana, the auxin signalling network is made...

Open AccessCorrection: Corrigendum: A fluorescent hormone biosensor reveals the dynamics of jasmonate signalling in plants
Nature Communications 6: Article number: 6043 (2015); Published: 16 January 2015; Updated: 10 February 2016. It has come to our attention that the control version of the Jas9-VENUS reporter construct reported ...

Reporters for sensitive and quantitative measurement of auxin response
Two fluorescent reporters allow high-resolution visualization of auxin response; DR5v2 is more sensitive than existing auxin response reporters, and a ratiometric version of DII-Venus named R2D2 allows for acc...

Open AccessA fluorescent hormone biosensor reveals the dynamics of jasmonate signalling in plants
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 bi...

Analysis of 3D gene expression patterns in plants using whole-mount RNA in situ hybridization
Rozier et al. provide a Protocol for whole-mount mRNA in situ hybridization in complex plant tissues. The method is fully compatible with colorimetric or fluorimetric signal detection, including the Tyramide Sign...

Structural basis for oligomerization of auxin transcriptional regulators
The plant hormone auxin is a key morphogenetic regulator acting from embryogenesis onwards. Transcriptional events in response to auxin are mediated by the auxin response factor (ARF) transcription factors and...

Signal integration by GSK3 kinases in the root
Signal integration is central to the regulation of patterning during plant development. During lateral root initiation, a signalling pathway controlled by the phloem-secreted TDIF peptide is found to activate ...

Cytokinin signalling inhibitory fields provide robustness to phyllotaxis
The regularly spaced arrangement of plant organs around the stem known as phyllotaxis depends on auxin-based inhibitory fields; this study identifies another hormone-based inhibitory field downstream of auxin ...
