“…This result agrees with the positive correlation between symbiosis performance parameters and CAT activity. In several studies, it has been stated that CAT activity decreases under stress conditions (Mhadhbi et al 2004(Mhadhbi et al , 2008Nandwal et al 2007) which is consistent with our results. Nevertheless, decline level of CAT activity in nodules formed by CP-36 strain was greater than that in nodules of C-15 strain.…”

Chickpea plants were inoculated with two strains of Mesorhizobium ciceri: local strain (C-15) and non-local strain in order to evaluate plant growth parameters, activities of nitrogenase and antioxidant enzymes under drought stress as well as control condition within 15 days of imposition of drought stress. Biomass production, nodulation, nitrogen fixation and antioxidant enzyme activities under drought condition were compared. Under control condition, symbiotic efficiency in symbiosis formed by C-15 was higher than that in symbiosis derived by CP-36. Although drought stress decreased shoot dry weight, root dry weight, nodule dry weight and nitrogen fixation in both symbioses, the rate of decline in plants inoculated with CP-36 was higher than that in symbiosis chickpea with C-15. Therefore, symbioses showed different tolerance level under drought condition which was essentially correlated with symbiotic performance at nonstressful conditions. Under drought stress, nodular peroxidase (POX) activity increased in both symbioses but was higher in nodules produced by C-15. Ascorbate peroxidase (APX) increased significantly in nodules of symbiosis of chickpea with C-15. Catalase (CAT) and glutation reductase (GR) declined in both symbioses which decline extent in symbiosis with C-15 was lower than that in the nodules of CP-36. These results suggested contribution of rhizobial partner in enhancing the tolerance of symbioses to drought stress, which was related with the increase of antioxidant enzyme activities (APX and POX) under drought conditions.

“…Pro is known to have an osmoprotective function during the plant response to drought, cold, salt, and heavy metal treatment (Cook et al, 2004;Singh et al, 2004;Gong et al, 2005;Charlton et al, 2008;Shulaev et al, 2008;Urano et al, 2009). Furthermore, Pro was also shown to accumulate in nodules of Cicer arietinum and Vicia faba during salt stress (Trinchant et al, 1998;Nandwal et al, 2007). Nitrogen fixation was less sensitive to osmotic stress in M. truncatula plants overaccumulating Pro (Verdoy et al, 2006).…”

Soybean Metabolites Regulated in Root Hairs in Response to the Symbiotic BacteriumBradyrhizobium japonicum

et al. 2010

Nodulation of soybean (Glycine max) root hairs by the nitrogen-fixing symbiotic bacterium Bradyrhizobium japonicum is a complex process coordinated by the mutual exchange of diffusible signal molecules. A metabolomic study was performed to identify small molecules produced in roots and root hairs during the rhizobial infection process. Metabolites extracted from roots and root hairs mock inoculated or inoculated with B. japonicum were analyzed by gas chromatography-mass spectrometry and ultraperformance liquid chromatography-quadrupole time of flight-mass spectrometry. These combined approaches identified 2,610 metabolites in root hairs. Of these, 166 were significantly regulated in response to B. japonicum inoculation, including various (iso)flavonoids, amino acids, fatty acids, carboxylic acids, and various carbohydrates. Trehalose was among the most strongly induced metabolites produced following inoculation. Subsequent metabolomic analyses of root hairs inoculated with a B. japonicum mutant defective in the trehalose synthase, trehalose 6-phosphate synthase, and maltooligosyltrehalose synthase genes showed that the trehalose detected in the inoculated root hairs was primarily of bacterial origin. Since trehalose is generally considered an osmoprotectant, these data suggest that B. japonicum likely experiences osmotic stress during the infection process, either on the root hair surface or within the infection thread.

“…Many authors indicated a decrease in water related parameters short after NaCl treatment (Boughalleb et al, 2012;Hernandez and Almansa, 2002;Kholova et al, 2010;Morales et al, 1998;Nandwal et al, 2007;Sairam et al, 2002;Stępień and Kłobus, 2006) and also after long growth in saline conditions (35 mM or 70 mM NaCl) some changes in water balance in L. esculentum plants were noticed (RomeroAranda et al, 2001). We also revealed the depletion of leaf hydration (H) at high salinity in the early phase of the experiment which was correlated with cell plasmolysis observed in light microscopy.…”

“…Accumulation of osmoprotectants including sugars is quite common under salinity stress in plants e.g. Brassica oleracea (Elavoumoottil et al, 2003), Lupinus albus (Fernandez et al, 2004), Zea mays (Kholova et al, 2010), Phaseolus vulgaris (Stoeva and Kaymakanova, 2008), Cicer arietinum (Nandwal et al, 2007), Tamarix ramosissima (Carter and Nippert, 2011), Nitraria retusa (Boughalleb et al, 2012), Centaurea ragusina (Radić et al, 2013). Also in L. esculentum, high amounts of proline (Gapińska et al, 2007), glycinebetaine (Mäkelä et al, 2000) and soluble sugars (Khavari-Nejad and Mostofi, 1998) under salt conditions were reported.…”

Five-week-old tomato plants (Lycopersicon esculentum) cv. Perkoz grown in pots containing garden soil in a growth chamber were submitted to 50 or 150 mM NaCl for 1 h, 2 and 5 days. Tomato leaf anatomy generally did not change after short time salinity, except 5-day-treatment with 150 mM NaCl, where changed cell shape (shrunk and deformed) simultaneously with increased volume of intercellular spaces (IS) were observed. Although leaf hydration (H) depleted only 1 h after 150 mM NaCl treatment both salt concentrations generated two coexisting populations of saltaffected mesophyll cells: (i) slightly-affected (Sl-A) which showed incipient plasmolysis or slightly changed shapes, and (ii) severely-affected (Sv-A) which showed severe plasmolysis; serious deformation of cell shape or disorganization including cell degeneration. In Sl-A cells salinity changed location and shape of chloroplasts which were: more rounded, with oversized starch grains (SG) (2d) or more flat (5d). Salt-mediated changes were becoming more distinguished and pronounced with length of 150 mM NaCl treatment. The amount of salt-affected cells was changing during the experiment and depended on the salt concentration. In 50 mM-treated plants salt-affected cells appeared 1 h after treatment (~40%) and raised up to 78% on 2 nd day, however the population of Sl-A cells dominated. In 150 mM NaCl-treated plants the percentage of affected cells raised during the experiment from 75% to 99%. Firstly Sl-A cells dominated, but on the 5 th day the majority was Sv-A. Salt-affected cells were distributed quite evenly in palisade or spongy mesophyll, except 2 d after treatment with 50 mM NaCl, when their number was higher in the palisade mesophyll. Sv-A cells in the spongy mesophyll were located mostly near the bundle while in the palisade mesophyll more irregularly. Different susceptibility of cells to salt stress might be the consequence of an unequal distribution of osmotic stress and subsequent ionic stress or physiological state of cells.Keywords: leaf hydration, mesophyll cells, osmotic stress, plasmolysis, salt stress, tomato 219Journal of Central European Agriculture, 2014, 15(3), p.219-235 DOI: 10.5513/JCEA01/15.3.1478Streszczenie 5-tygodniowe rośliny pomidora (Lycopersicon esculentum) odm. Perkoz, które rosły w doniczkach z ziemią ogrodniczą w komorze hodowlanej zostały poddane działaniu NaCl o stężeniu 50 mM lub 150 mM przez okres 1 godz., 2 i 5 dni. Krótkotrwałe zasolenie nie wywołało zmian anatomicznych w liściach pomidora, za wyjątkiem zmian kształtu komórek (obkurczenie i deformacje) i towarzyszącemu im zwiększeniu powierzchni przestrzeni międzykomórkowych, co obserwowano po 5 dniach od traktowania roślin NaCl w stężeniu 150 mM. Pomimo, iż istotny spadek uwodnienia liści odnotowano jedynie po godzinie od podania 150 mM NaCl, oba zastosowane stężenia generowały powstawanie w mezofilu dwóch grup komórek: (i) lekko zmienionych (LZ) -w początkowych stadiach plazmolizy lub o delikatnie zmienionych kształtach oraz (ii) mocno zmienionych (MZ) -z za...
