  • AUXIN
  • A model is proposed showing the putative role of polar auxin transport and resulting auxin accumulation in initiation of subsequent changes in auxin homeostasis and signal perception with a particular role of Aux/IAA expression. (frontiersin.org)
  • developmental
  • Adventitious root (AR) formation in the stem base (SB) of cuttings is the basis for propagation of many plant species and petunia is used as model to study this developmental process. (frontiersin.org)
  • Adventitious root (AR) formation is a developmental process which on the one hand reflects the great plasticity of plants to adjust to stressful environmental conditions and to regenerate plant structures on the same individual independent of sexual reproduction. (frontiersin.org)
  • AR formation can be induced on intact plants according to the developmental program and in response to environmental factors such as stress factors. (frontiersin.org)
  • AHK3
  • In 4-5-day-old etiolated A. thaliana seedlings, treatment with cytokinin resulted in the strongest expression activation of the constructs P AHK2 -GUS and P AHK3 -GUS. (deepdyve.com)
  • In the leaves of three-week-old plants with actively functioning chloroplasts, treatment with cytokinin mainly stimulated expression of the construct P AHK3 -GUS. (deepdyve.com)
  • gene
  • The development of defined protoplast transient expression systems for high-throughput screening and systematic characterization of gene functions has greatly contributed to elucidating plant signal transduction pathways, in combination with genetic, genomic, and transgenic approaches. (plantphysiol.org)
  • Although plant TFs usually consist of gene families, CRES-T is effective, in principle, even for the TFs with functional redundancy. (frontiersin.org)
  • Marker-free P-DNAs are transferred to plant cell nuclei together with conventional T-DNAs carrying a selectable marker gene. (plantphysiol.org)
  • Thus, WRKY60 might be a direct target gene of WRKY18 and WRKY40 in ABA signaling. (biomedcentral.com)
  • Long-term seedling growing in darkness on medium containing cytokinin resulted in the substantial promoter activation of the gene encoding the histidine kinase AHK2. (deepdyve.com)
  • At the same time, cytokinin activated the promoter of the gene of primary response to cytokinin in the construct P ARR5 -GUS. (deepdyve.com)
  • Agrobacterium is a genus of Gram-negative bacteria that uses horizontal gene transfer to cause tumors in many plant species with agricultural and economic importance including woody ornamental shrubs (rose), vines (grape), shade trees, fruit trees (cherry, berry, walnut), and herbaceous perennials. (frontiersin.org)
  • 2002
  • Much of the research to date on plant oxylipins is focused on the jasmonate family of molecules generated by the AOS branch pathway ( Howe and Schilmiller, 2002 ). (plantphysiol.org)
  • regulates
  • The NSF 2010 project focuses on defining the network of interactions by which cytokinin regulates plant growth and development, and includes the analysis of additional transcription factors as well as proteins interacting with the primary signaling pathway. (bio.net)
  • overexpression
  • In CRES-T, overexpression of a chimeric repressor, composed of the coding sequence of a transcription factor (TF) and short peptide designated as the repression domain, could interfere with the action of endogenous TF in plants. (frontiersin.org)
  • AHK2
  • In 4-5-day-old etiolated A. thaliana seedlings, treatment with cytokinin resulted in the strongest expression activation of the constructs P AHK2 -GUS and P AHK3 -GUS. (deepdyve.com)
  • synthesis
  • Their homeostasis is regulated by the rate of de novo synthesis, the import rate, the formation and breakdown of cytokinin conjugates (which are mainly glycosides), and the rate of export and catabolism ( Mok and Mok, 2001 ). (plantcell.org)
  • hence
  • While this process occurs at very low frequencies in nature, it can be induced in culture and by mutation, and hence is being exploited to accelerate plant breeding ( Germanà, 2011 ). (biologists.org)
  • shoots
  • Leafy spurge plants treated with sub-lethal concentrations of foliar-applied glyphosate produce new vegetative shoots with reduced main stem elongation and increased branching. (biomedcentral.com)
  • However, abundance of shikimate was similar in a subsequent generation of aerial shoots derived from crown buds of treated and untreated plants, suggesting EPSPS is no longer inhibited or abundance of shikimate initially observed in crown buds dissipated over time. (biomedcentral.com)
  • Overall, auxins, gibberellins (precursors and catabolites of bioactive gibberellins), and cytokinins (precursors and bioactive cytokinins) were more abundant in the aboveground shoots derived from glyphosate-treated plants. (biomedcentral.com)
  • mainly
  • In the leaves of three-week-old plants with actively functioning chloroplasts, treatment with cytokinin mainly stimulated expression of the construct P AHK3 -GUS. (deepdyve.com)
