Light regulates xylem cell differentiation via PIF in Arabidopsis (2022)
Journal Article
Ghosh, S., Nelson, J., Cobb, G., Etchells, J., & de Lucas, M. (2022). Light regulates xylem cell differentiation via PIF in Arabidopsis. Cell Reports, 40(3), Article 111075. https://doi.org/10.1016/j.celrep.2022.111075

The balance between cell proliferation and differentiation in the cambium defines the formation of plant vascular tissues. As cambium cells proliferate, subsets of daughter cells differentiate into xylem or phloem. TDIF-PXY/TDR signaling is central t...

Journal Article
Mesejo, C., Marzal, A., Martinez Fuentes, A., Reig, C., de Lucas, M., Iglesias, D. J., Primo Millo, E., Blazquez, M. A., & Agusti, M. (2022). Reversion of fruit‐dependent inhibition of flowering in Citrus requires sprouting of buds with epigenetically silenced CcMADS19. New Phytologist, 233(1), 526 - 533. https://doi.org/10.1111/nph.17681

In Citrus, the response to environmental floral inductive signals is inhibited by the presence of developing fruits. The mechanism involves epigenetic activation of the CcMADS19 locus (FLC orthologue), encoding a floral repressor. To understand how t...

PIF4‐induced BR synthesis is critical to diurnal and thermomorphogenic growth (2018)
Journal Article
Martínez, C., Espinosa‐Ruíz, A., de Lucas, M., Bernardo‐García, S., Franco‐Zorrilla, J. M., & Prat, S. (2018). PIF4‐induced BR synthesis is critical to diurnal and thermomorphogenic growth. The EMBO Journal, 37(23), Article e99552. https://doi.org/10.15252/embj.201899552

The Arabidopsis PIF4 and BES1/BZR1 transcription factors antagonize light signaling by facilitating co‐activated expression of a large number of cell wall‐loosening and auxin‐related genes. While PIF4 directly activates expression of these targets, B... Read More about PIF4‐induced BR synthesis is critical to diurnal and thermomorphogenic growth.

Regulation of Root Angle and Gravitropism (2018)
Journal Article
Toal, T. W., Ron, M., Gibson, D., Kajala, K., Splitt, B., Johnson, L. S., Miller, N. D., Slovak, R., Gaudinier, A., Patel, R., de Lucas, M., Provart, N. J., Spalding, E.

Regulation of plant root angle is critical for obtaining nutrients and water and is an important trait for plant breeding. A plant's final, long-term root angle is the net result of a complex series of decisions made by a root tip in response to chan... Read More about Regulation of Root Angle and Gravitropism.

TOPLESS mediates brassinosteroid control of shoot boundaries and root meristem development in Arabidopsis thaliana (2017)
Journal Article
Espinosa-Ruiz, A., Martinez, C., de Lucas, M., Fabregas, N., Bosch, N., Cano-Delgado, A. I., & Prat, S. (2017). TOPLESS mediates brassinosteroid control of shoot boundaries and root meristem development in Arabidopsis thaliana. Development, 144(9), 1619-1628. https://doi.org/10.1242/dev.143214

The transcription factor BRI1-EMS-SUPRESSOR 1 (BES1) is a master regulator of brassinosteroid (BR)-regulated gene expression. BES1 together with BRASSINAZOLE-RESISTANT 1 (BZR1) drive activated or repressed expression of several genes, and have a prom...

Transcriptional Regulation of Arabidopsis Polycomb Repressive Complex 2 Coordinates Cell Type Proliferation and Differentiation. The Plant Cell, 28(10), 2616-2631. https://doi.org/10.1105/tpc.15.00744

Spatiotemporal regulation of transcription is fine-tuned at multiple levels, including chromatin compaction. Polycomb Repressive Complex 2 (PRC2) catalyzes the trimethylation of Histone 3 at lysine 27 (H3K27me3), which is the hallmark of a repressive...

Plant somatic cells are generally acknowledged to retain totipotency, the potential to develop into any cell type within an organism. This astonishing plasticity may contribute to a high regenerative capacity on severe damage, but how plants control...
