Metabarcoding the Bacterial Assemblages Associated with in the Mexican Central Pacific.

The Mexican Central Pacific (MCP) region has discontinuous coral ecosystems with different protection and anthropogenic disturbance. Characterizing the bacterial assemblage associated with the sea urchin and its relationship with environmental variables will contribute to understanding the species' physiology and ecology. We collected sea urchins from coral ecosystems at six sites in the MCP during the summer and winter for two consecutive years.

Geographic isolation and long-distance gene flow influence the genetic structure of the blue fan palm Brahea armata (Arecaceae).

The formation of the Baja California Peninsula (BCP) has impacted the microevolutionary dynamics of different species in ways that depend on biological traits such as dispersal capacity. Plants with relatively low levels of vagility have exhibited high genetic divergence between the BCP and Continental mainland. Brahea armata (Arecaceae) is a palm species inhabiting the northern part of the BCP and Sonora; its distribution occurs in isolated oases of vegetation.

Characterization of the plastome of and comparative analysis of eight species of .

In this study, we sequenced, assembled, and annotated the plastome of Mill. and compared it with seven species of the genus Sequencing, annotating, and comparing plastomes allow us to understand the evolutionary mechanisms associated with physiological functions, select possible molecular markers, and identify the types of selection that have acted in different regions of the genome. The plastome of is 157,000 bp long and presents the typical quadripartite structure with a large single-copy (LSC) region of 87,267 bp and a small single-copy (SSC) region of 18,501 bp, which are separated by two inverted repeat (IRs) regions of 25,616 bp each.

Complete chloroplast genome of Lam. (Solanaceae).

is a perennial wild tomatillo with traditional use in central Mexico because of its edible fruits. Due to their agronomic potential and nutraceutical properties, this species is a resource that can be a candidate to plant breeding programs to be included in the Mexican diet. Here, we report the complete chloroplast genome of .

Complete sequence of wild chloroplast genome.

Lam. has horticultural importance because of its edible fruits. Cultivated and wild populations grow in Mexico.

Physalis and physaloids: A recent and complex evolutionary history.

The complex evolutionary history of the subtribe Physalinae is reflected in the poor resolution of the relationships of Physalis and the physaloid genera. We hypothesize that this low resolution is caused by recent evolutionary history in a complex geographic setting. The aims of this study were twofold: (1) To determine the phylogenetic relationships of the current genera recognized in Physalinae in order to identify monophyletic groups and resolve the physaloid grade; and (2) to determine the probable causes of the recent divergence in Physalinae.
