Studies on the Leaf Nodules V The Formation of Knobs by the Effect of Antibiotics on theArdisia crispa andA. punctata

Tamotsu YAMADA Shokubutsugaku Zasshi 1955. doi:10.15281/jplantres1887.68.267

Other claims from this paper (8)

Intervention effect Antibiotics induced knobs and stopped growth in A. crispa seedlings.
Intervention effect Antibiotics induced knobs and stopped growth in A. punctata seedlings.
Intervention effect A. japonica did not form knobs after antibiotic or heat treatment.
Association Knob formation increased with antibiotic concentration and treatment duration.
Observation A. crispa had a higher knob-forming ratio than A. punctata under the same treatment.
Observation Knobs contained epidermis, cortex and central cylinder, with no meristem or leaf-nodule-bacteria detected.
Observation Knob structure resembled that after heat treatment.
Mechanism The authors proposed that a substance secreted by dying leaf-nodule bacteria induces knob formation and may contribute to leaf nodules.

Observation The genetically defined HSY spans approximately 8.5 Mb.
Observation The X counterpart extends about 5.4 Mb.
Observation The X counterpart includes a 900 Kb region containing shared Knob 1.
Observation The HSY sequence is expanded by 4 Mb relative to the corresponding X sequence.
Observation Genetically defined borders coincide with shared BACs on the HSY and X tiling paths.
