Implications of Below-Ground Allelopathic Interactions of Camelina sativa and Microorganisms for Phosphate Availability and Habitat Maintenance
Implications of Below-Ground Allelopathic Interactions of Camelina sativa and Microorganisms for Phosphate Availability and Habitat Maintenance
Toxic breakdown products of young Camelina sativa (L.) Crantz, glucosinolates can elim-inate microorganisms in the soil. Since microorganisms are essential for phosphate cycling, onlyinsensitive microorganisms with phosphate-solubilizing activity can improve C. sativa’s phosphatesupply. In this stud...

Toxic breakdown products of young Camelina sativa (L.) Crantz, glucosinolates can elim-inate microorganisms in the soil. Since microorganisms are essential for phosphate cycling, onlyinsensitive microorganisms with phosphate-solubilizing activity can improve C. sativa’s phosphatesupply. In this study, 33P-labeled phosphate, inductively coupled plasma mass spectrometry and potexperiments unveiled that not only Trichoderma viride and Pseudomonas laurentiana used as phosphate-solubilizing inoculants, but also intrinsic soil microorganisms, including Penicillium aurantiogriseum,and the assemblies of root-colonizing microorganisms solubilized as well phosphate from apatite,trigger off competitive behavior between the organisms. Driving factors in the competitiveness areplant and microbial secondary metabolites, while glucosinolates of Camelina and their breakdownproducts are regarded as key compounds that inhibit the pathogen P. aurantiogriseum, but also seemto impede root colonization of T. viride. On the other hand, fungal diketopiperazine combined withglucosinolates is fatal to Camelina. The results may contribute to explain the contradictory effects ofphosphate-solubilizing microorganisms when used as biofertilizers. Further studies will elucidateimpacts of released secondary metabolites on coexisting microorganisms and plants under different environmental conditions. |
