The Complete Genome Sequences of 12 Species of Plants from the Yucatan Peninsula, Mexico.

We present the complete genome sequences of 12 species of plants from Campeche, Mexico and the greater Yucatan Peninsula: Agave americana, Agave angustifolia, Agave fourcroydes, Agave karwinskii, Agave potatorum, Agave tequiliana, Annona squamosa, Cedrela odorata, Pouteria campechiana, Pouteria glomerata, Trichilia hirta and Trichilia minutiflora.

Diversity and Interactomics of Bacterial Communities Associated with Dominant Trees During Tropical Forest Recovery.

Bacterial communities have been identified as functional key members in soil ecology. A deep relation with these communities maintains forest coverture. Trees harbor particular bacteriomes in the rhizosphere, endosphere, or phyllosphere, different from bulk-soil representatives. Moreover, the plant microbiome appears to be specific for the plant-hosting species, varies through season, and responsive to several environmental factors. This work reports the changes in bacterial communities associated with dominant pioneer trees [Tabebuia rosea and Handroanthus chrysanthus [(Bignoniaceae)] during tropical forest recovery chronosequence in the Mayan forest in Campeche, Mexico. Massive 16S sequencing approach leads to identifying phylotypes associated with rhizosphere, bulk-soil, or recovery stage. Lotka-Volterra interactome modeling suggests the presence of putative regulatory roles of some phylotypes over the rest of the community. Our results may indicate that bacterial communities associated with pioneer trees may establish more complex regulatory networks than those found in bulk-soil. Moreover, modeled regulatory networks predicted from rhizosphere samples resulted in a higher number of nodes and interactions than those found in the analysis of bulk-soil samples.
