Auxin is a major hormone controlling almost every growth and developmental process in plants. Auxin exerts such a control through local auxin gradients, tight control of homeostasis and the regulation of gene expression. Auxin-dependent transcriptional regulation involves a variety of modular TIR1/AFB ...
To determine whether Dcaa acts through the auxin signaling pathway, we first analyzed its effect on the expression of the auxin responsive-reporterDR5:GUSandDR5rev:GFPand used NAA as a control. TheDR5:GUSseedlings displayed GUS signals in the quiescent center (QC) and columella cells of the ...
Compatible plant-virus interactions result in dramatic changes of the plant transcriptome and morphogenesis, and are often associated with rapid alterations in plant hormone homeostasis and signalling. Auxin controls many aspects of plant organogenesis, development, and growth; therefore, plants can rapidly...
Plant hormones are small active molecules acting in concert to control many aspects of plant growth, development, and adaptive responses to environmental stimuli. Most plant hormones are small chemical molecules acting at rather low concentrations either locally or after short- or long-distance transport...
Auxin is known to regulate gene expression through TIR1/AFBs-mediated signaling4,25,28. Therefore, we presumed that the regulation of genes related to chromatin accessibility would be downstream of the TIR1/AFBs pathway. To identify such genes, we analyzed gene expression in MM2d cells treated...
In general, the synthesis of hormones in plants is not restricted to a particular, specialized tissue. Moreover, there is also extensive crosstalk between different hormonal and other signaling pathways that ultimately determine physiological outcomes (reviewed in Davies, 2004). The plasticity of plant...
in plants. Extensivegeneticstudies have revealed the pathways of auxin production,auxin transport, and auxin signaling. Auxin is mainly derived from the samebiosynthetic pathwayastryptophan, and also from a tryptophan-independent pathway. It is produced particularly in shoot and root meristems and is ...
ticulum (ER), has been implicated in an independent, non- transcriptional auxin signaling pathway, acting primarily in cell elongation and cell division (Sauer and Kleine-Vehn, 2011; Xu et al., 2014). Cytokinins The first step in the biosynthesis of cytokinin is the addition of ...
• RAF-like kinases connect fast auxin signaling to cytoplasmic streaming Summary The plant-signaling molecule auxin triggers fast and slow cellular responses across land plants and algae. The nuclear auxin pathway mediates gene expression and controls growth and development in land plants, but this...
Plants sense and respond to endogenous signals and environmental cues to ensure optimal growth and development. Plant cells must integrate the myriad transduction events into a comprehensive network of signalling pathways and responses. The phytohormone
