Systems analysis of metabolism and the transcriptome in Arabidopsis thaliana roots reveals differential co-regulation upon iron, sulfur and potassium deficiency

, 2017
Deprivation of mineral nutrients causes significant retardation of plant growth. This retardation is associated with nutrient specific and general stress-induced transcriptional responses.

Pleiotropic effects of potassium deficiency in a heterocystous, nitrogen-fixing cyanobacterium, Anabaena torulosa [PDF]

, 1998
Omission of potassium from the growth medium caused multiple metabolic impairments and resulted in cessation of growth of the filamentous, heterocystous, nitrogen-fixing cyanobacterium Anahaena torulosa, during both diazotrophic and nitrogen-supplemented

Transcriptome and weighted gene co-enrichment analysis revealed modules and candidate genes associated with barley response to low potassium stress

Frontiers in Plant Science
Potassium deficiency is one of the key factors affecting crop yields. This study investigated the effects of low potassium stress on the growth of three barley varieties from physiological and biochemical indicators, transcriptomics and weighted gene co ...

Changes in plant morphology and dry matter partitioning caused by potassium deficiency in Gossypium hirsutum (L.)

, 2010
Cotton plants are frequently exposed to potassium deficiency but knowledge is limited on the effects of this stress at the organ and plant scale. A greenhouse experiment was conducted to: (i) assess the impact of both mild and severe potassium deficit ...

The sodium-potassium pump controls the intrinsic firing of the cerebellar Purkinje neuron [PDF]

, 2012
In vitro, cerebellar Purkinje cells can intrinsically fire action potentials in a repeating trimodal or bimodal pattern. The trimodal pattern consists of tonic spiking, bursting, and quiescence.

Morphological, physiological, biochemical, and transcriptome analysis of Phyllostachys edulis seedlings response to low potassium

Plant Stress
Potassium (K+) is an indispensable mineral nutrient for the growth and development of plants. Understanding how plants cope with low-K+ stress exerts a crucial role in enhancing breeding programs aimed at improving tolerance to K+ deficiency.

Recurrent blocked duct(s) in a mother with immunoglobulin A deficiency

, 2008
Secretory immunoglobulin A (sIgA) is the dominant immunoglobulin in human milk, and apart from the obvious contribution it makes towards the protection of the infant, sIgA may also form an important part of the defense of the mammary gland.

Potassium loss with tissue potassium deficiency in rats during hypokinesia

, 2008
Background. This study aims at showing the effect of hypokinesia (HK) on tissue potassium (K+) loss with different tissue K+ depletion and tissue K+ deficiency with different K+ intake.
