Rank products: a simple, yet powerful, new method to detect differentially regulated genes in replicated microarray experiments
Phylogenetic relationships within cation transporter families of Arabidopsis.
TLDR
This analysis has focused on cation transporter gene families for which initial characterizations have been achieved for individual members, including potassium transporters and channels, sodium transporter, calcium antiporters, cyclic nucleotide-gated channels, cation diffusion facilitator proteins, natural resistance-associated macrophage proteins, and Zn-regulated transporter Fe-regulatedporter-like proteins.
The Potassium-Dependent Transcriptome of Arabidopsis Reveals a Prominent Role of Jasmonic Acid in Nutrient Signaling1[w]
TLDR
A novel role of JA in nutrient signaling and stress management through a variety of physiological processes such as nutrient storage, recycling, and reallocation is highlighted as well as a network of molecular processes underlying plant adaptation to K+ deficiency.
K + Nutrition and Na + Toxicity: The Basis of Cellular K + /Na + Ratios
TLDR
This Botanical Briefing will discuss the functions and interactions of genes and transporters in the broader context of K + nutrition and Na + toxicity in plants.
Mechanisms of Na+ Uptake by Plant Cells
Learning from evolution: Thellungiella generates new knowledge on essential and critical components of abiotic stress tolerance in plants.
TLDR
This review summarizes the current state of knowledge on Thellungiella and re-evaluates its usefulness as a model for research into plant stress tolerance.
EZ-Rhizo: integrated software for the fast and accurate measurement of root system architecture.
TLDR
EZ-Rhizo is described: a Windows-integrated and semi-automated computer program designed to detect and quantify multiple RSA parameters from plants growing on a solid support medium, and successfully applied to evaluate natural variation in RSA across 23 Arabidopsis thaliana accessions.
Arabidopsis thaliana cyclic nucleotide gated channel 3 forms a non-selective ion transporter involved in germination and cation transport.
TLDR
The ionic composition and ion uptake characteristics of wild-type and mutant seedlings suggests that the growth advantage in these conditions may be due to restricted ion influx in mutant plants, and that CNGC3 functions in the non-selective uptake of monovalent cations in Arabidopsis root tissue.
Multilevel Analysis of Primary Metabolism Provides New Insights into the Role of Potassium Nutrition for Glycolysis and Nitrogen Assimilation in Arabidopsis Roots1[W][OA]
TLDR
regulation of enzymes at the level of transcripts and proteins is likely to play an important role in plant adaptation to K deficiency by maintaining carbon flux into amino acids and proteins, decreasing negative metabolic charge, and increasing the nitrogen-carbon ratio in amino acids.
Hyperosmotic priming of Arabidopsis seedlings establishes a long-term somatic memory accompanied by specific changes of the epigenome
TLDR
Experience of transient hyperosmotic stress by young plants is stored in a long-term somatic memory comprising differences of chromatin status, transcriptional responsiveness and whole plant physiology.
