  • vitro
  • Overall, the current findings provide evidence on the interrelationship existing among the exogenous PGRs, phenotypic responses and the endogenous CKs in the in vitro regenerants. (springer.com)
  • Endogenous cytokinin (CK) levels of in vitro-cultured and greenhouse-acclimatized 'Williams' bananas treated with six aromatic CKs were quantified using UPLC-MS/MS. The underground parts had higher endogenous CK levels than the aerial parts. (usda.gov)
  • Germination
  • Endogenous jasmonates were detected in conifer somatic embryos for the first time, and reached maxima at germination. (frontiersin.org)
  • The differences in concentrations of various classes of phytohormones over the proliferation, maturation, desiccation, and germination in somatic P. abies embryos clearly indicate correlations between endogenous phytohormone profiles and particular developmental stages of the SE of conifers. (frontiersin.org)
  • physiological
  • Genetic manipulation of plant hormone cytokinins may influence several physiological processes, besides others stress tolerance, root formation and crop yield. (frontiersin.org)

  • seedlings
  • Endogenous cytokinins were quantified and identified in germinating achenes and developing seedlings of Tagetes minuta L. incubated at 25 °C over a 144 h period. (cas.cz)

  • purine
  • 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)
  • Content
  • The rise in iP content required the presence of BA and a-naphthaleneacetic acid (NAA) in the medium, suggesting that endogenous iP production is regulated in response to these growth regulator uptakes. (scielo.br)
  • Increasing grain yield by mean of manipulation of endogenous cytokinin content was assayed by the silencing of the HvCKX1 gene. (frontiersin.org)
  • phenotypically
  • However, amp1 mutants are phenotypically distinct from both cytokinin or CYCD3;1-overproducing plants and it is unclear what primary defect could account for the various aspects of the amp1 phenotype. (biologists.org)
  • derivatives
  • The individual cytokinin groups and the respective derivatives within each group did, however, not follow such a consistent trend. (cas.cz)
  • root meristem
  • We show that the increased growth of the primary root is linked to an enhanced meristematic cell number, suggesting that cytokinins control the exit of cells from the root meristem. (plantcell.org)
