ZULUETA RODRIGUEZ, Ramón et al. Mycorrhizal status of Jacaratia mexicana and presence of arbuscular mycorrhizal fungi in dry deciduous forests of the Gulf of Mexico. Rev. Mex. Mic [online]. 2010, vol.31, pp.37-44. ISSN 0187-3180.

We evaluated the mycorrhizal status of Jacaratia mexicana A. DC. and the presence of arbuscular mycorrhizal fungi (AMF) in three patches of dry deciduous forests located on the slope of the Gulf of Mexico. There were no mycorrhizal structures in any of the materials collected in field, and therefore the susceptibility of this specie to AMF was determined. The study revealed the presence of arbuscles and vesicles 15 days after inoculation. Six morphospecies were identified: Glomus intraradices, G. constrictum,G. sinuosum, Glomus sp. 1, Glomus sp. 2. and Entrophospora infrequens. The only related morphospecies in sampled sites were G. intraradices and G. sinuosum, and they were also fairly abundant in Veracruz (8, 870 and 5), Campeche (958 and 448) and Yucatán (3, 708 and 16). All of them have not been reported associated with J. mexicana in our country before.
