Amino acids regulate salinity-induced potassium efflux in barley root epidermis

TA Cuin, S Shabala - Planta, 2007 - Springer
The amino acid content increases substantially in salt-stressed plants. The physiological
relevance of this phenomenon remains largely unknown. Using the MIFE ion flux measuring …

Exogenously supplied compatible solutes rapidly ameliorate NaCl-induced potassium efflux from barley roots

TA Cuin, S Shabala - Plant and Cell Physiology, 2005 - academic.oup.com
It has been suggested that the role of compatible solutes in plant stress responses is not
limited to conventional osmotic adjustment, but also includes some other regulatory or …

Salicylic acid improves salinity tolerance in Arabidopsis by restoring membrane potential and preventing salt-induced K+ loss via a GORK channel

M Jayakannan, J Bose, O Babourina… - Journal of …, 2013 - academic.oup.com
Despite numerous reports implicating salicylic acid (SA) in plant salinity responses, the
specific ionic mechanisms of SA-mediated adaptation to salt stress remain elusive. To …

Difference in root K+ retention ability and reduced sensitivity of K+-permeable channels to reactive oxygen species confer differential salt tolerance in three Brassica …

K Chakraborty, J Bose, L Shabala… - Journal of Experimental …, 2016 - academic.oup.com
Brassica species are known to possess significant inter and intraspecies variability in salinity

Na+- K+ transport in roots under salt stress

I Zepeda-Jazo, S Shabala, Z Chen… - Plant Signaling & …, 2008 - Taylor & Francis
Salinity causes billion dollar losses in annual crop production. So far, the main avenue in
breeding crops for salt tolerance has been to reduce Na+ uptake and transport from roots to …

Root Plasma Membrane Transporters Controlling K+/Na+ Homeostasis in Salt-Stressed Barley

Z Chen, II Pottosin, TA Cuin, AT Fuglsang… - Plant …, 2007 - academic.oup.com
Plant salinity tolerance is a polygenic trait with contributions from genetic, developmental,

The cytosolic Na+ : K+ ratio does not explain salinity‐induced growth impairment in barley: a dual‐tracer study using 42K+ and 24Na+

HJ Kronzucker, MW Szczerba… - Plant, Cell & …, 2006 - Wiley Online Library
It has long been believed that maintenance of low Na+: K+ ratios in the cytosol of plant cells
is critical to the plant's ability to tolerate salinity stress. Direct measurements of such ratios …

K+ retention in leaf mesophyll, an overlooked component of salinity tolerance mechanism: A case study for barley

H Wu, M Zhu, L Shabala, M Zhou… - Journal of integrative …, 2015 - Wiley Online Library
Plant salinity tolerance is a physiologically complex trait, with numerous mechanisms
contributing to it. In this work, we show that the ability of leaf mesophyll to retain K+ …

Signalling by potassium: another second messenger to add to the list?

S Shabala - Journal of experimental botany, 2017 - academic.oup.com
The total pool of available energy is considered as 100% under control conditions and
diminishes with increased stress severity (duration). When plant cell cytosolic [K+] is high …

How do plants maintain pH and ion homeostasis under saline-alkali stress?

J Li, Y Yang - Frontiers in Plant Science, 2023 - frontiersin.org
Salt and alkaline stresses often occur together, severely threatening plant growth and crop
yields. Salt stress induces osmotic stress, ionic stress, and secondary stresses, such as …
