“…These outcomes suggest that there was a competition between Na + and K + regarding their uptake. Similar findings were reported with green bean (Yasar et al, 2006) and canola (Bandeh-Hagh et al, 2008). Salinity-induced decrease in the accumulation of K + was recorded in barley (Tavakkoli et al, 2011).…”

Maize (Zea mays L.) is the world's leading edible oil and third largest important cereal. In addition to it is used as food for human consumption as well as food grain for livestock. High concentrations of NaCl in soils account for large decrease in the yield of a large variety of crops all over the globe. The objective of the present study was conducted to evaluate NaCl stress on growth and mineral nutrient composition of maize plants. Maize seeds were grown in plastic pots having fine sand. After 20 days of germination, the plants were subjected to seven different concentrations (Control, 25mM, 50mM, 75mM, 100mM, 125mM and 150mM) of NaCl. Plants were analyzed on 15 th day after salt treatment. Factorial experiments in a completely randomized design (CRBD) with three replications were applied. The growth parameters and mineral contents Na, Ca, K and Cl were investigated from saline treated and non saline treated plants. Results indicated that the NaCl stress markedly reduced the shoot and root length fresh and dry masses. Moreover Na + , Cl -content increased with increase in NaCl stress, while Ca 2+ and K + were decreased significantly.

“…The rss4 mutant accumulated more Na + in whole plants (particularly in shoot tissue) than the wildtype under salt‐stressed conditions, indicating that the reduced salt tolerance of the rss4 mutant might be attributable principally to enhanced Na + toxicity to shoots. Salt stress generally differentially influences Na + accumulation by old and young tissues (Vera‐Estrella et al, 2005; Yasar et al, 2006; Wang et al, 2012a, 2012b). Both the rss4 mutant and the wildtype accumulated more Na + in old leaves (leaves 1 and 2) than in newly emerged leaves (leaf 3) when subjected to salt stress, thus protecting young leaves from ion‐induced damage (Fig.…”

Identification and Fine Mapping of a Mutation Conferring Salt‐Sensitivity in Rice (Oryza sativa L.)

Single‐gene mutants tolerant or sensitive to salt stress are ideal materials for identifying and cloning genes related to salt tolerance in rice (Oryza sativa L.). In the present study, a salt‐sensitive mutant was obtained from the ethyl methanesulfonate (EMS)‐induced Nipponbare bank. The mutant, designated rice salt sensitive 4 (rss4), showed a significant increase in salt sensitivity at the seedling stage and accumulated high levels of Na+ in shoots, particularly in the blades of old leaves, under conditions of NaCl stress. Genetic analysis indicated that the mutation was controlled by a single recessive gene. Quantitative trait locus (QTL) analysis for shoot Na+ content was performed using an F2 population derived from a cross between the rss4 mutant and the indica cultivar Zhaiyeqing 8 (ZYQ8). Three QTLs were identified and one located on the long arm of chromosome 6 was determined to be the candidate locus of the rss4 gene based on comparison and analysis, which explained 40.5% of the phenotypic variance in the shoot Na+ content of the F2 population. Further analysis of recombination events in 165 mutant individuals of an enlarged mapping population of rss4/ZYQ8 defined the rss4 locus to an interval of 230.5 kb bracketed by markers RM20566 and IM28706 on chromosome 6.

“…Only as the degree of salt stress increased were other leaves affected sequentially: old-to-young leaves in Arabidopsis and the opposite in E. salsugineum. It is well known that salt stress has different effects on old and young tissues (Vera-Estrella et al, 2005;Yasar et al, 2006;Munns and Tester, 2008;Wang et al, 2012). In rice (Oryza sativa), for instance, young leaves are protected by accumulation of Na + and Cl -ions in the older leaves possibly due to differential expression of ion transporter genes .…”

Growth Platform-Dependent and -Independent Phenotypic and Metabolic Responses of Arabidopsis and Its Halophytic Relative, Eutrema salsugineum, to Salt Stress

Comparative studies of the stress-tolerant Arabidopsis (Arabidopsis thaliana) halophytic relative, Eutrema salsugineum, have proven a fruitful approach to understanding natural stress tolerance. Here, we performed comparative phenotyping of Arabidopsis and E. salsugineum vegetative development under control and salt-stress conditions, and then compared the metabolic responses of the two species on different growth platforms in a defined leaf developmental stage. Our results reveal both growth platform-dependent and -independent phenotypes and metabolic responses. Leaf emergence was affected in a similar way in both species grown in vitro but the effects observed in Arabidopsis occurred at higher salt concentrations in E. salsugineum. No differences in leaf emergence were observed on soil. A new effect of a salt-mediated reduction in E. salsugineum leaf area was unmasked. On soil, leaf area reduction in E. salsugineum was mainly due to a fall in cell number, whereas both cell number and cell size contributed to the decrease in Arabidopsis leaf area. Common growth platform-independent leaf metabolic signatures such as high raffinose and malate, and low fumarate contents that could reflect core stress tolerance mechanisms, as well as growth platform-dependent metabolic responses were identified. In particular, the in vitro growth platform led to repression of accumulation of many metabolites including sugars, sugar phosphates, and amino acids in E. salsugineum compared with the soil system where these same metabolites accumulated to higher levels in E. salsugineum than in Arabidopsis. The observation that E. salsugineum maintains salt tolerance despite growth platform-specific phenotypes and metabolic responses suggests a considerable degree of phenotypic and metabolic adaptive plasticity in this extremophile.
