  • activators
  • In the light of recent work showing that DNA-binding proteins associated with the yeast co-repressor TUP1 can also function as activators, we have examined the transcriptional activity of the YABs. (biomedcentral.com)
  • interactions
  • In this study we present a simple bioinformatics methodology that uses public, carefully curated microarray data and the mutual information algorithm ARACNe in order to obtain a database of transcriptional interactions. (biomedcentral.com)
  • However, obtaining a complete overview of the transcriptional interactions for a given organism or developmental process is still a challenging and expensive task. (biomedcentral.com)
  • How these disparate functions are regulated is not clear, but based on interactions with the LEUNIG-class of co-repressors, it has been proposed that YABs act as transcriptional repressors. (biomedcentral.com)
  • tuberization
  • Sergeeva, L. 2009-06-28 00:00:00 We studied the interaction of the day length, cytokinins, and gibberellins in the control of tuberization in potato (Solanum tuberosum L, cv. (deepdyve.com)
  • transcription factors
  • DELLA proteins act as hubs that relay environmental information to the multiple transcriptional circuits that control growth and development through physical interaction with transcription factors from different families. (upv.es)
  • AHK3
  • 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)
  • ribosides
  • but cytokinins can also exist in inactive forms as ribosides (in which a ribose sugar is attached to the N 9 nitrogen of the purine ring) and as ribotides (in which the ribose moiety contains a phosphate group). (biologists.org)
  • interaction
  • Mt NIN, Mt RR1, and Mt RR4 define a common pathway activated during early S. meliloti interaction, allowing crosstalk between plant cytokinins and bacterial Nod factors signals. (plantcell.org)
  • initiation
  • Moreover, the fidelity of transcriptional initiation by RNA polymerase II is postulated to be quite low in vivo and up to 90% of polymerase II initiation events may correspond to "transcriptional noise" [ 5 ], which makes it difficult to distinguish between background and functional RNAs.

  • root
  • 1. Cytokinin was shown to act as the organ-to-organ signal, transmitted from the root to shoot, for the presence of nitrate in the soil. (nii.ac.jp)
