Ethylene antagonists increase nodulation on sym 5 pea mutants


Progress in plant growth regulations Proceedings of the 14th International Conference on Plant Growth Substances, Amsterdam, Netherlands, 21-26 July 1991: 530-533
Ethylene antagonists increase nodulation on sym 5 pea mutants
Seeds of Sparkle and the symbiosis (sym5) mutant, E2 (phenotypically normal, poor nodulation at a root temperature of 20 degrees C and increased nodulation at 12 degrees C), were planted in vermiculite inoculated with Rhizobium leguminosarum. Roots from 7-day-old seedlings were treated with the ethylene inhibitors Ag2SO4, aminoethoxyvinylglycine (AVG) or Co(NO3)2 and nodules were counted at 28 days. AVG, Co2+ or Ag+ increased nodulation of E2 at 20 degrees C but not Sparkle.
