high mycorrhizal specificity in a widespread mycoheterotrophic plant, eulophia zollingeri (orchidaceae). | because mycoheterotrophic plants fully depend on their mycorrhizal partner for their carbon supply, the major limiting factor for the geographic distribution of these plants may be the presence of their mycorrhizal partner. although this factor may seem to be a disadvantage for increasing geographic distribution, widespread mycoheterotrophic species nonetheless exist. the mechanism causing the wide distribution of some mycoheterotrophic species is, however, seldom discussed. we identified the my ... | 2008 | 21632319 |
