Journal ArticleDOI
A Central Regulatory System Largely Controls Transcriptional Activation and Repression Responses to Phosphate Starvation in Arabidopsis
Regla Bustos,Gabriel Castrillo,Francisco Scaglia Linhares,María Isabel Puga,Vicente Rubio,Julián Pérez-Pérez,Roberto Solano,Antonio Leyva,Javier Paz-Ares +8 more
TL;DR: This paper showed that PHR1 and PHL1 are partially redundant transcription factors acting as central integrators of starvation responses, both specific and generic, and they indicate that transcriptional repression responses are an integral part of adaptive responses to stress.
Journal ArticleDOI
SPX1 is a phosphate-dependent inhibitor of PHOSPHATE STARVATION RESPONSE 1 in Arabidopsis
María Isabel Puga,I. Mateos,Rajulu Charukesi,Zhiye Wang,José Manuel Franco-Zorrilla,Laura de Lorenzo,M. L. Irigoyen,Simona Masiero,Regla Bustos,Jose Rodriguez,Antonio Leyva,Vicente Rubio,Hans Sommer,Javier Paz-Ares +13 more
TL;DR: DNA-binding and pull-down assays showed that SPX1 is a competitive inhibitor of PHR1 binding to its recognition sequence, and that its efficiency is highly dependent on the presence of Pi or phosphite, a nonmetabolizable Pi analog that can repress PSRs.
Journal ArticleDOI
Plant hormones and nutrient signaling.
Vicente Rubio,Regla Bustos,M. L. Irigoyen,Ximena Cardona-López,Mónica Rojas-Triana,Javier Paz-Ares +5 more
TL;DR: This review summarizes evidences and analyzes possible transcriptional correlations between hormonal and nutritional responses, as a means to further characterize the role of hormones in the response of plants to limiting nutrients in soil.
Journal ArticleDOI
Dissection of local and systemic transcriptional responses to phosphate starvation in Arabidopsis
Marie-Christine Thibaud,Jean-François Arrighi,Vincent Bayle,Serge Chiarenza,Audrey Creff,Regla Bustos,Javier Paz-Ares,Yves Poirier,Laurent Nussaume +8 more
TL;DR: In this paper, a split-root assay was performed to mimic a heterogeneous environment, after which a transcriptomic analysis identified groups of genes either locally or systemically regulated by P(i) starvation at the transcriptional level.
Journal ArticleDOI
The transcriptional control of plant responses to phosphate limitation
José Manuel Franco-Zorrilla,Esperanza Gonzalez,Regla Bustos,Francisco Scaglia Linhares,Antonio Leyva,Javier Paz-Ares +5 more
TL;DR: In this review, the current knowledge of this regulatory system is summarized, the hallmark of which is the central role of transcription factor PHR1 in the co-ordinated regulation of many phosphate-starvation-responsive genes.
