TI  - Effect of a myo-Inositol Antagonist, 2-O, C-Methylene-myo-Inositol, on the 
      Metabolism of myo-Inositol-2-H and d-Glucose-1-C in Lilium longiflorum Pollen.
PG  - 658-63
AB  - 2-O,C-Methylene-myo-inositol (MMO), a myo-inositol (MI) antagonist, inhibits 
      germination and tube elongation of pollen from Lilium longiflorum cv. Ace or 44. 
      The presence of 5 mm MMO in Dickinson's pentaerythritol medium (Plant Physiol. 
      43:1-8) partially blocks germination. The tubes produced are short and fail to 
      elongate. In the presence of MI, MMO's toxic effect is blocked. As little as 0.56 
      mm MI will maintain normal germination in the presence of 43 mm MMO, and pollen 
      tubes continue to elongate for 2 to 3 hr. Eventually, the toxic action of MMO 
      prevents further growth. MMO does not inhibit UDP-d-glucose dehydrogenase from 
      lily pollen.Uptake of MI-2-(3)H and incorporation of tritium into galacturonic 
      acid and pentose units of tube wall pectin are blocked by MMO. The site of this 
      inhibition is undertermined. Uptake of d-glucose-1-(14)C and incorporation of 
      (14)C into 70% ethyl alcohol-insoluble polysaccharides of germinated pollen are 
      not blocked by MMO, but distribution of label into polysaccharide product is 
      altered. In MMO-treated pollen, very little (14)C is found in uronic acid or 
      pentose units. At 30 mm MMO, about two-thirds of the carbon flow from d-glucose 
      to these pectic components is interrupted. MMO also alters d-glucose metabolism 
      in the 70% ethyl alcohol-soluble fraction, but the compound involved must still 
      be identified.These results offer fresh evidence of an intermediary role for MI 
      during UDP-d-glucuronate biosynthesis in germinated pollen.
