  • abscisic
  • Induced plant growth and development of various plants by inoculation with PGPR having phytohormone, such as indole-3-acetic acid (IAA), cytokinins (CK), gibberelic acid (GA), salicylic acid (SA) and abscisic acid (ABA) producing ability, has been repeatedly documented. (springer.com)
  • vitro
  • Plant regeneration can be achieved in vitro from explants of plant tissue cultured in hormone containing medium. (frontiersin.org)
  • By contrast, the recalcitrance of Rubus tissues to regenerate in vitro has impeded the development of robust transformation protocols in these species, although a few number of studies have successfully obtained transgenic plants carrying genes of interest. (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)
  • amounts
  • The system is sensitive enough to detect picogram amounts of TM in milligram tissue samples. (oregonstate.edu)
  • This can be done by grinding freeze-dried or fresh plant tissue (gram amounts) in a mortar with a pestle under liquid nitrogen then adding an appropriate solvent to the ground material. (springer.com)
  • BACKGROUND: We have developed a new analytical approach for isolation and quantification of cytokinins (CK) in minute amounts of fresh plant material, which combines a simple one-step purification with ultra-high performance liquid chromatography-fast scanning tandem mass spectrometry.

  • organs
  • 2011 ). Following the emergence of multicellularity, cell specialisation increased as tissues and organs with diverse specific functions evolved. (springer.com)
  • chromatography-mass spectrometry
  • The occurrence of IAAsp in pea root and nodule tissue was confirmed unequivocally by gas chromatography-mass spectrometry (GC-MS). The following endogenous indole compounds were also unequivocally identified in pea root nodules by GC-MS: IAA, indole-3-pyruvic acid, indole-3-lactic acid, indole-3-propionic acid, indole-3-butyric acid, and indole-3-carboxylic acid.

  • isolation
  • In an attempt to understand the role of IAA in bud formation in Douglas-fir tissues in culture, a method for the rapid isolation and quantitation of endogenous IAA levels was developed. (oregonstate.edu)
  • In this review, we summarise current understanding of these principles, methodologies for plant hormone analysis, factors that complicate their extraction and isolation from the highly complex matrices of plant and other tissues (which contain thousands of substances) and future perspectives.

My team studies the molecular mechanisms of cytokinin signal reception in plant using biochemical and immunochemical methods, and methods of genetic engineering. (bio.net)
  • previously
  • With the exception of IAA and indole-3-propionic acid, these compounds have not previously been unequivocally identified in a higher plant tissue. (springer.com)
  • Previously, we have isolated and characterized a cytokinin-binding protein with the molecular mass of 70 kDa (CBP-70) and showed its receptor properties [1, (bio.net)
