Isolation of Acanthamoeba Species and Bacterial Symbiont Variability in Puna Salt Plains, Argentina. [PDF]

Environ Microbiol Rep
Acanthamoeba isolated from the extreme environments of the Puna salt plains in Argentina contain unique intracellular microbial communities that are distinct from those found in the surrounding environments. The number of shared taxa amongst intracellular amoebae across all sites was greater than the number of shared taxa between the amoebae and their ...

Ribcage Morphology in Native South American Populations From Different Altitudes: Insights From a Global Comparative Framework. [PDF]

Am J Hum Biol
ABSTRACT Objectives Altitude shapes human morphology as highland populations must cope with cold and hypoxic environments. Although Andean highlanders have been proposed to exhibit larger and deeper ribcages, this idea is mainly based on research using disarticulated skeletal elements or non‐South American controls. The objective of this research is to

Linear Plasmids in Micrococcus: Insights Into a Common Ancestor and Transfer by Conjugation. [PDF]

Environ Microbiol
Comparative analysis indicates a common ancestor for linear plasmids in Micrococcus strains from Andean Puna, suggesting that horizontal gene transfer helps native microbes survive extreme conditions. The successful transfer of pLMA1 by conjugation also shows its potential as a genetic vector.

A survey of the Sli gene in wild and cultivated potato. [PDF]

Plant Direct
Abstract Inbred‐hybrid breeding of diploid potatoes necessitates breeding lines that are self‐compatible. One way of incorporating self‐compatibility into incompatible cultivated potato (Solanum tuberosum) germplasm is to introduce the S‐locus inhibitor gene (Sli), which functions as a dominant inhibitor of gametophytic self‐incompatibility.
