Disease relevance of Friazole

 

High impact information on Friazole

  • In addition, lep-1 is less responsive to GA and more sensitive to the GA biosynthesis inhibitor paclobutrazol, indicating that LEP is a positive regulator of GA-induced germination [4].
  • Conversely, a loss-of-function rgl1 line had reduced GA4 expression and exhibited GA-independent activation of seed germination, leaf expansion, flowering, stem elongation, and floral development, as detected by resistance to the GA biosynthesis inhibitor paclobutrazol [5].
  • Treatments with gibberellin (GA) and paclobutrazol, a GA biosynthesis inhibitor, as well as crosses with GA-deficient mutants indicate that FPF1 is involved in a GA-dependent signaling pathway and modulates a GA response in apical meristems during the transition to flowering [6].
  • We have utilized a modified expression cloning strategy to identify a developmentally regulated gene from Drosophila melanogaster that encodes a RNase that we refer to as Clipper (CLP) [7].
  • Inclusion of exogenous gibberellic acid into the in vitro bud culture system with the paclobutrazol not only prevented the CHRC mRNA down-regulation, it up-regulated transcript accumulation to the level of gibberellic acid-treated corollas [8].
 

Biological context of Friazole

  • A similar phenotype was obtained when wild-type petunia plants were treated with the GA-biosynthesis inhibitor, paclobutrazol [9].
  • The Visible Genetics Clipper sequencer is a new platform for automated DNA sequencing which employs disposable MicroCel cassettes and 50 microm thick polyacrylamide gels [1].
  • The inhibition of celery cell growth by paclobutrazol could be partially overcome by addition of cholesterol to the culture medium [10].
  • Both cultivars displayed more or less the same cell numbers (3.7 x 10(7) for Clipper and 3.2 x 10(7) cfu/g for Prisma) after the third day of germination [11].
  • Results showed that, irrespective of growth conditions, Sahara had much larger root biomass than Clipper and consequently substantially more P was allocated to roots in Sahara than in Clipper [12].
 

Anatomical context of Friazole

 

Gene context of Friazole

  • Furthermore, paclobutrazol, an inhibitor of gibberellin synthesis, induced a similar effect on control and transgenic dark-grown hypocotyls suggesting that gibberellin biosynthesis was probably not altered in seedlings overexpressing hFUT3 [15].
  • Gibberellic acid rapidly enhanced, whereas paclobutrazol down-regulated, the steady-state level of CHRD [16].
  • Recessive, presumed loss-of-function alleles of GAI confer normal height and resistance to the GA biosynthesis inhibitor paclobutrazol [17].
  • The isolation, cloning, and sequencing of two full-length cDNAs corresponding to the root tip forms of the maize (Zea mays L. cv Clipper) annexins p33 and p35 are described [18].
  • Inhibition of GA biosynthesis with paclobutrazol (PAC) prevented hook formation in wild-type (WT) seedlings and in constitutive ethylene response (ctr)1-1, a mutant that exhibits a constitutive ethylene response [19].
 

Analytical, diagnostic and therapeutic context of Friazole

  • With proper usage, the optical and electronic subsystems of the Clipper sequencer do not limit the data collection or sequence-determination processes [1].
  • Three (1----4)-beta-D-xylan xylanohydrolases (xylan endohydrolases, EC 3.2.1.8) have been purified 1200-2800-fold from extracts of germinated barley (Hordeum vulgare L. cv. Clipper) by a sequence of ammonium sulphate fractionation, Procion-blue-dye chromatography, ion-exchange and gel filtration chromatography [20].
  • Regulation of growth of Lilium plantlets in liquid medium by application of paclobutrazol or ancymidol, for its amenability in a bioreactor system: growth parameters [21].
  • A rapid and sensitive liquid chromatography/electrospray ionization/tandem mass spectrometry (LC-ESI-MS-MS) method has been developed for the determination of the plant growth regulator paclobutrazol in pear samples [22].
