Amino acids regulate salinity-induced potassium efflux in barley root epidermis
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
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
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 …
Brassica species are known to possess significant inter and intraspecies variability in salinity
stress tolerance, but the cell-specific mechanisms conferring this difference remain elusive …

Na+- K+ transport in roots under salt stress
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 …

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
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+ …
