The origins and development of the arid and highly seasonal steppe-desert biome in Central Asia, the largest of its kind in the world, remain largely unconstrained by existing records. It is unclear how Cenozoic climatic, geological, and biological forces, acting at diverse spatial and temporal scales, shaped Central Asian ecosystems through time. Our synthesis shows that the Central Asian...

Genome insights of the plant-growth promoting bacterium Cronobacter muytjensii JZ38 with volatile-mediated antagonistic activity against Phytophthora infestans

Eida, Abdul Aziz ; Bougouffa, Salim ; L’Haridon, Floriane ; Alam, Intikhab ; Weisskopf, Laure ; Bajic, Vladimir B. ; Saad, Maged M. ; Hirt, Heribert

In: Frontiers in Microbiology, 2020, vol. 11, p. 369

Salinity stress is a major challenge to agricultural productivity and global food security in light of a dramatic increase of human population and climate change. Plant growth promoting bacteria can be used as an additional solution to traditional crop breeding and genetic engineering. In the present work, the induction of plant salt tolerance by the desert plant endophyte Cronobacter sp. ...

The fossil record of the genus Varanus from the Southern Caucasus (Armenia, Georgia)

Vasilyan, Davit ; Bukhsianidze, Maia

In: PeerJ, 2020, p. e8322

The Southern Caucasus, with its special geographic position and complex topography, is a well-known biodiversity hotspot. However, the formation of this hotspot remains largely unstudied. To reveal this, a thorough study of the fossil record of the region is necessary. In the present paper, we describe for the first time fossil monitor lizards (Varanus sp.) from two late Miocene localities from...

Cooccurrence of NDM-1, ESBL, RmtC, AAC(6′)-Ib, and QnrB in Clonally Related Klebsiella pneumoniae Isolates Together with Coexistence of CMY-4 and AAC(6′)-Ib in Enterobacter cloacae Isolates from Saudi Arabia

Al-Agamy, Mohamed H. ; El-Mahdy, Taghrid S. ; Radwan, Hesham H. ; Poirel, Laurent

In: BioMed Research International, 2019, p. -

The aim of this study was to investigate the mechanisms responsible for resistance to antimicrobials in a collection of enterobacterial isolates recovered from two hospitals in Saudi Arabia. A total of six strains isolated from different patients showing high resistance to carbapenems was recovered in 2015 from two different hospitals, with four being Klebsiella pneumoniae and two...

A Boundary Property for Upper Domination

AbouEisha, Hassan ; Hussain, Shahid ; Lozin, Vadim ; Monnot, Jérôme ; Ries, Bernard ; Zamaraev, Viktor

In: Lecture Notes in Computer Science, 2016, vol. 9843, p. 229-240

An upper dominating set in a graph is a minimal (with respect to set inclusion) dominating set of maximum cardinality. The problem of finding an upper dominating set is generally NP-hard, but can be solved in polynomial time in some restricted graph classes, such as P4-free graphs or 2K2-free graphs. For classes defined by finitely many forbidden induced subgraphs, the boundary separating...
