  • meristem
  • We demonstrate that AHP6-based fields establish patterns of cytokinin signalling in the meristem that contribute to the robustness of phyllotaxis by imposing a temporal sequence on organ initiation. (cpib.ac.uk)
  • Auxin Transport
  • The identification of plants that spontaneously form nodules ( 13 - 15 ), together with the observations that ectopic application of cytokinins ( 16 ) or auxin transport inhibitors ( 17 ) to the root surface lead to the development of nodule-like structures, demonstrates that the machinery required for NP development is intrinsic to the plant.

  • ARRs
  • On the other hand, the type-A ARRs act as repressors of cytokinin-activated transcription. (nih.gov)
  • Type-A ARRs contain a central receiver domain along with short N- and C-terminal extensions and are transcriptionally induced by cytokinin. (plantcell.org)
  • AHK3
  • Cytokinins are perceived by three histidine kinases--CRE1/WOL/AHK4, AHK2, and AHK3--which initiate intracellular phosphotransfer. (nih.gov)
  • compounds
  • The compounds were further tested for cytokinin activity in several cytokinin bioassays. (springer.com)
  • The synthesis of a new group of 2-X-6-anilinopurines, including compounds with potential cytokinin-like activities, with various substitutions (X=H, halogen, amino, methylthio or nitro) on the phenyl ring is described. (nih.gov)
  • synthesis
  • We suggest that the combination of simple synthesis, lowered cytokinin activity, and enhanced inhibitory effects on CKX isoforms, makes 3FMTDZ and HETDZ suitable candidates for in vivo studies. (springer.com)
  • Cycloheximide (Chx) blocks both G 1 phase progression ( 13 ) and protein synthesis in these cells ( 14 ) and did not inhibit CycD3 induction by cytokinin ( Fig. 1 D), showing that induction is independent of progression through G 1 and involves signal transduction by proteins already present in stationary phase cells. (sciencemag.org)
  • tissue
  • Synthesized in roots, cytokinins move upward in the xylem (woody tissue) and pass into the leaves and fruits, where they are required for normal growth, for cell differentiation, and, in conjunction with auxin (another plant hormone), to promote cell division. (britannica.com)
  • The impact of pathogen-derived cytokinins on the total cytokinin content of infected tissue and host gene expression was minimal in wild type plants. (springer.com)
  • degradation
  • Aremu AO, Masondo NA, Sunmonu TO, Kulkarni MG, Zatloukal M, Spichal L, Doležal K, Van Staden J (2014) A novel inhibitor of cytokinin degradation (INCYDE) influences the biochemical parameters and photosynthetic apparatus in NaCl-stressed tomato plants. (springer.com)
  • activates
  • At the Biodynamics Research Team in the Plant Productivity Systems Research Group at the RIKEN Plant Science Center, investigations have shown that cytokinin, a plant hormone that activates cell division, is closely associated with rice yields. (innovations-report.com)
  • interactions
  • Crosstalk between auxin and cytokinin plays important roles in the development of other meristematic tissues, however hormone interaction studies to date have focused on more accessible later-stage gynoecia and the spatiotemporal interactions pivotal for patterning of early gynoecium primordia remain unknown. (plantphysiol.org)
  • perturbations
  • Gall formation is thought to involve perturbations in phytohormone homeostasis, particularly of auxin and cytokinin and more recently brassinosteroids, contributing to the altered morphogenic processes within the root and hypocotyl (Ludwig-Müller et al. (springer.com)
  • Furthermore, our results demonstrate that young LRP are more sensitive to perturbations in the cytokinin activity than are developmentally more advanced primordia. (plantcell.org)
