SHR overexpression induces the formation of supernumerary cell layers with cortex cell identity in rice (2017)
Journal Article
Henry, S., Dievart, A., Divol, F., Pauluzzi, G., Meynard, D., Swarup, R., Wu, S., Gallagher, K., & Périn, C. (2017). SHR overexpression induces the formation of supernumerary cell layers with cortex cell identity in rice. Developmental Biology, 425(1), 1-7. https://doi.org/10.1016/j.ydbio.2017.03.001

The number of root cortex cell layers varies among plants, and many species have several cortical cell layers. We recently demonstrated that the two rice orthologs of the Arabidopsis SHR gene, OsSHR1 and OsSHR2, could complement the A. thaliana shr m...

Pre-mRNA alternative splicing (AS) generates protein variants from a single gene that can create novel regulatory opportunities. In this issue of Developmental Cell, Li et al. (2016) present a high-resolution expression map of AS events in Arabidopsi... Read More about One gene, many proteins: mapping cell-specific alternative splicing in plants.

Cytokinin acts through the auxin influx carrier AUX1 to regulate cell elongation in the root (2016)
Journal Article
Street, I. H., Mathews, D. E., Yamburkenko, M. V., Sorooshzadeh, A., John, R. T., Swarup, R., Bennett, M. J., Kieber, J. J., & Schaller, G. E. (2016). Cytokinin acts through the auxin influx carrier AUX1 to regulate cell elongation in the root. Development, 143(21), 3982-3993. https://doi.org/10.1242/dev.132035

Hormonal interactions are critical for plant development. In Arabidopsis, cytokinins inhibit root growth through effects on cell proliferation and cell elongation. Here we define key mechanistic elements in a regulatory network by which cytokinin inh...

Auxin represents a key signal in plants, regulating almost every aspect of their growth and development. Major breakthroughs have been made dissecting the molecular basis of auxin transport, perception, and response. In contrast, how plants control t...

M., Scheres, B., Peret, B., & Bennett, M. J. (2016). Lateral root emergence in Arabidopsis is dependent on transcription factor LBD29 regulation of auxin influx carrier LAX3. Development, 143(18), 3340-3349. https://doi.org/10.1242/dev.136283

Lateral root primordia (LRP) originate from pericycle stem cells located deep within parental root tissues. LRP emerge through overlying root tissues by inducing auxin-dependent cell separation and hydraulic changes in adjacent cells. The auxin-induc...
