Mobilization and transfer of nine macro-and micronutrients to Pinus greggii seedlings via arbuscular mycorrhizal fungi

Resumen
Traditionally, it is thought that arbuscular mycorrhizae establish a symbiosis with the roots of numerous angiosperm and some gymnosperm families. However, the mobilization and transfer of macro- and micronutrients to Pinaceae via arbuscular mycorrhizal fungi (AMF) has not been reported so far. The present work evaluated whether arbuscular mycorrhizae are able to establish, mobilize, and transfer nutrients in the neotropical species of Pinaceae, Pinus greggii.Seedlings were inoculated with 3 AMF consortia isolated from an agricultural site, a Cupressus lusitanica forest and a Pinus hartwegii forest. Evidence of mobilization and transfer of macro- and micronutrients in plants inoculated with the 3 consortia was evaluated. A greater Mg, Mn, and Zn mobilization and transfer was observed in plants inoculated with the pine forest AMF consortium after 7 months. In addition to these positive effects, AMF root colonization of 10 to 15% and 21 to 36% was observed depending on the AMF consortia after 2 and 7 months. In the present work, we report for the first time that AMF mobilize and transfer N, P, K, Ca, Mg, Fe, Mn, Zn, Cu, and B to a member of Pinaceae, indicating that this mycorrhizal symbiosis is more complex than previously believed.|Traditionally, it is thought that arbuscular mycorrhizae establish a symbiosis with the roots of angiosperm plants.

The present work evaluated whether arbuscular mycorrhizae are able to establish and mobilize nutrients in the neotropical Pinaceae Pinus greggii. The seedlings of this tree were inoculated with three consortia of AMF isolated from an agricultural site, a forest of Cupressus lusitanica and a forest of Pinus hartwegii. There was evidence of translocation of macro- and micronutrients in plants inoculated with the three consortia evaluated. Translocation was greater for Mg, Mn and Zn in plants inoculated with the consortium of fungi from the pine forest after 7 months. In addition to these positive effects, colonization of 10 to 15% and 20 to 38% was observed depending on the AMF consortia after 2 and 7 months, respectively. In the present work, we report for the first time that AMF mobilize N, P, K, Ca, Mg, Fe, Mn, Zn, Cu and B in gymnosperms, indicating that this mycorrhizal symbiosis is more complex than previously believed.
