Activation of Glucosidase via Stress-Induced Polymerization Rapidly Increases Active Pools of Abscisic Acid
View on Elsevier
Long-distance signalling of abscisic acid (ABA): the factors regulating the intensity of the ABA signal.
TLDR
Root growth-promoting microorganisms in the rhizosphere, lateral ABA flows in the root cortex across apoplastic barriers, ABA redistribution in the stem, leaf apoplastics pH values, and the action of beta-glucosidases play an important role in the regulation of signal intensity.

Pedobacter arcticus sp. nov., a facultative psychrophile isolated from Arctic soil, and emended descriptions of the genus Pedobacter, Pedobacter heparinus, Pedobacter daechungensis, Pedobacter…
TLDR
A Gram-stain-negative, short rod-shaped, motile (by gliding) bacterial strain, designated A12(T), was isolated from tundra soil collected from Ny-Ålesund, in the Arctic region of Norway and named Pedobacter arcticus sp.

Water flows in the parasitic association Rhinanthus minor/Hordeum vulgare.
TLDR
Water uptake, deposition and transpiration in Rhinanthus were dramatically increased after attachment to the barley host; most of the water used by the parasite was extracted as xylem sap from the host, thereby scavenging 20% of the total water taken up by the host's roots.

Mucilaginibacter soli sp. nov., isolated from Arctic tundra soil.
TLDR
A novel pale-pink-coloured strain, designated R9-65(T), was isolated from a tundra soil near Ny-Ålesund, Svalbard Archipelago, Norway, and is considered to represent a novel species of the genus Mucilaginibacter, for which the name Mucilsinibacter soli sp.

Abscisic acid (ABA) flows from Hordeum vulgare to the hemiparasite Rhinanthus minor and the influence of infection on host and parasite abscisic acid relations.
Using the facultative root hemiparasite Rhinanthus minor and Hordeum vulgare as a host, the flows, depositions, and metabolism of abscisic acid (ABA) within the host, within the parasite, and between…

Huanghella arctica gen. nov., sp. nov., a bacterium of the family Cytophagaceae isolated from Arctic tundra soil.
A novel, strictly aerobic, red-pigmented, gram-reaction-negative bacterium, designated strain R9-9(T), was isolated from tundra soil collected near Ny-Ålesund, Svalbard Archipelago, Norway (78° N).…

Multiple impacts of the plant growth-promoting rhizobacterium Variovorax paradoxus 5C-2 on nutrient and ABA relations of Pisum sativum
TLDR
Whether bacterial ACCd attenuates root to shoot ABA signalling requires further investigation, since ABA is critical to maintain growth of droughted plants, and ACCd-containing organisms have been advocated as a means of minimizing growth inhibition of plants in drying soil.

Pedobacter huanghensis sp. nov. and Pedobacter glacialis sp. nov., isolated from Arctic glacier foreland.
TLDR
Two psychrotolerant, Gram-stain-negative, rod-shaped bacterial strains, designed M1-27(T) and 8-24(T), were subjected to polyphasic taxonomic studies and showed that the two strains were grouped with members of the genus Pedobacter, but represented distinct taxa.
