Yerba mate () genome provides new insights into convergent evolution of caffeine biosynthesis.

Yerba mate (YM, ) is an economically important crop marketed for the elaboration of mate, the third-most widely consumed caffeine-containing infusion worldwide. Here, we report the first genome assembly of this species, which has a total length of 1.06 Gb and contains 53,390 protein-coding genes.

A multicopy suppressor screening approach as a means to identify antibiotic resistance determinant candidates in Yersinia pestis.

Background: Yersinia pestis is the causative agent of plague and a potential agent of bioterrorism and biowarfare. The plague biothreat and the emergence of multidrug-resistant plague underscore the need to increase our understanding of the intrinsic potential of Y. pestis for developing antimicrobial resistance and to anticipate the mechanisms of resistance that may emerge in Y.
