Draft genome sequence data of Antarctic . strain E22, from Deception Island.

Here, we report the draft genome sequence and assembly of the . strain E22, which was isolated from Antarctic soil of Deception Island, South Shetland Islands close to the Antarctic Peninsula. The genome was sequenced using a 2 # 250 bp paired-end method by Illumina MiSeq 6000.

Genome Sequence of sp. Strain ATA002, a Seed Endophytic Bacterium from the Atacama Desert.

The Gram-positive diazotrophic seed endophytic bacterium sp. strain ATA002 was isolated from seeds of the endemic cactus Maihueniopsis domeykoensis collected in the Atacama Desert, Chile. Here, we present a circular genome sequence, obtained by Nanopore sequencing, with a size of 3,904,590 bp and a GC content of 65.

Deep weathering in the semi-arid Coastal Cordillera, Chile.

The weathering front is the boundary beneath Earth's surface where pristine rock is converted into weathered rock. It is the base of the "critical zone", in which the lithosphere, biosphere, and atmosphere interact. Typically, this front is located no more than 20 m deep in granitoid rock in humid climate zones.

Root endophytic Penicillium promotes growth of Antarctic vascular plants by enhancing nitrogen mineralization.

Fungal endophyte associations have been suggested as a possible strategy of Antarctic vascular plants for surviving the extreme environmental conditions of Antarctica. However, the mechanisms by which this occurs are still poorly understood. The role of root fungal endophytes in nitrogen mineralization and nutrient uptake, as well as their impact on the performance of Antarctic plants, were studied.
