Abstract The effect of salicylic acid (SA) on the salt (NaCl) tolerance mechanism was studied in canola plants (oilseed rape, Brassica napus L.) by molecular and physiological experiments in plant tissue culture. Seeds of B. napus ‘Ocapy’ were germinated at 0, 50, and 100 mM NaCl on Murashige and Skoog (MS) medium containing different levels (0, 2, and 5 μM) of SA for 4 weeks. Total chlorophyll, carotenoid, and flavonoid content increased in response to interactive effects of SA and NaCl treatments at some concentrations. Proline content was increased under salt and SA treatments in shoot and root tissues. Salt alone and in combination with SA increased the total soluble protein content of shoots only, while the different concentrations of SA in the culture media affected variously the total soluble protein content. Protein patterns of shoots and roots showed some remarkable differences, based on gel electrophoresis and the consequent analysis of bands by ImageJ program. The relative expression of 15 and 12 protein bands in shoots and roots, respectively, differed under the applied treatments. In addition, the protein profile indicated that salinity and SA regulate the expression of salt-stress-inducible proteins as well as induced de novo synthesis of specific polypeptides. The findings may help to explain the salt tolerance mechanisms and to produce salt-tolerant canola plants.

Potential alleviation effects of Homobrassinosteroid (HBR) (0.5 and 1 µM HBR) on root germination, cell division and antioxidant system enzymes (superoxide dismutase and catalase) of barley (Hordeum vulgare L. cv. ‘Hilal’) roots grown under different salt concentrations (150 mM and 250 mM) were investigated during 48 and 72 h at dark with their controls. Salt applications decreased primary root lengths, seminal root lengths, number of roots from one seed, mitotic activity and induced mitotic abnormalities. In addition, salt application decreased protein content but increased enzyme activities both at 48 h and 72 h when compared to control. Roots treated with HBR enhanced root lengths and root number. HBR-treated roots showed more mitotic activity, mitotic abnormalities and significant enlargements at the root tips when compared to controls and only salt-treated samples. Salt + HBR applications stimulated root lengths and showed more mitotic activity and mitotic abnormalities when compared to only salt-treated samples. Salt application increased superoxide dismutase and catalase activities both at 48 h and 72 h.  However, HBR application decreased total soluble protein content and increased enzyme activities especially at 48 h compared to control. Depending on concentration and timing, salt + HBR treatments showed varying results in total soluble protein content and enzyme activities. There was also a significant change in protein banding patterns of experimental groups separated by SDS-PAGE. These findings are expected to contribute to understanding of how HBR affect barley roots grown under different salt concentrations.

Allelochemical Stress

Successive lettuce cultivation in closed hydroponics using the same nutrient solution causes the excess production and accumulation of allelochemicals. The accumulated allelochemicals induce oxidative damage and lipid peroxidation in plants leading to growth inhibition. In this study, we investigated the allelochemicals that induced oxidative damage and lipid peroxidation in lettuce grown in a once used non-renewed nutrient solution (1NR) and a twice used non-renewed nutrient solution (2NR) obtained from the successive cultivation and the alleviation of these damages through electro-degradation (ED). The 1NR solution was used for six weeks for a one-time lettuce cultivation while the 2NR solution was used for twelve weeks for a two-times lettuce cultivation. The results showed that the allelochemical stress caused growth inhibition in the lettuce in both the 1NR and 2NR solutions. It was observed that there was a higher generation of H2O2 and O2.– as well as a lower activity of the antioxidant enzymes, such as superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (POD), and ascorbate peroxidase (APX) in the roots of the plants grown in both the 1NR and 2NR solutions compared to plants grown in the new nutrient solution. The higher level of lipid peroxidation due to the higher MDA (malondialdehyde) content and higher soluble protein content were also observed in the roots of those plants. It was evident that lettuce root damage occurred due to accumulation of the allelochemicals in the 1NR and 2NR solutions. These damaged roots could not function normally nor uptake water and minerals from the culture solution. As a result, retarded lettuce growth was observed in the 1NR and 2NR solutions. The oxidative damage, soluble protein content, lipid peroxidation and ultimately growth retardation were more pronounced in the plants grown in the 2NR solution compared to the plants grown in the 1NR solution. The application of ED to the 1NR and 2NR solutions maintained the plant growth through less oxidative damage, soluble protein production and lipid peroxidation as was observed in the plants grown with the new nutrient solution. Therefore, the ED of a non-renewed culture solution would alleviate the allelochemical stress in lettuce under recycled hydroponics.

The objective of this study was to evaluate soluble protein content of protein hydrolysates obtained by enzymatic hydrolysis of apple snail using a trypsin enzyme. Apple snail were collected from traditional market at Pabean-Sidoarjo. Trypsin enzyme was used in enzymatic hydrolysis. The two variables, enzyme/substrate (E/S) ( 0.01, 0.05, 0.1) ratio and hydrolysis time (3 h, 6 h, 9 h, 12 h, 15 h, 18 h) and was used to produce the apple snail hydrolysate. The result showed that soluble protein content was about 2.3%-4.52%. The increase E/S ratio and hydrolysis time, the higher soluble protein content values was. The highest total soluble protein was achieved E/S 0.1 ratio at 12 h, 4.52%. But, after 12 h hydrolysis time, soluble protein was decreased. Optimum treatment to hydrolyzing apple snail using trypsin enzyme was E3H4 treated (E/S 0.1 ratio and 3 h)

Musa paradisiaca cv Lang belongs to cooking banana group, and it has high potential to be used in banana chips production. Like other cultivars, M. paradisiaca cv Lang is susceptible towards water shortage, therefore affecting banana growth and productivity. In this study, to mimic the drought condition, pseudo-drought stress was given to in vitro Lang banana seedlings by adding polyethylene glycol (PEG). Overall, decrement of roots length and chlorophyll (Chl) content was displayed by the seedlings exposed to 1%, 2%, 3%, 4%, and 5% (w/v) of PEG after three weeks of exposure. The proline content, total soluble protein content, and antioxidant capacity in leaf and roots, however, countered differently towards different levels of drought. Proline content showed the highest in leaf of 2% (w/v) PEG-treated seedling (12.66±0.38 µmoles/g) while the total soluble protein content showed the highest in roots of 5% (w/v) of PEG-treated seedling (30.65±1.07 mg/g FW). Antioxidant capacity of stressed seedlings revealed the catalase (CAT), guaiacol peroxidase (POD), and ascorbate peroxidase (APX) activities were the highest in the leaf of 1% (w/v) (10.69±5.06 µmol/min/mg), 4% (w/v), (0.079±0.03 µmol/min/mg), and 5% (w/v) (9.11±8.47 µmol/min/mg) of PEG- treated seedlings, respectively. Meanwhile, the highest CAT, POD, and APX activities in the roots were determined in 3% (w/v) (0.49±0.04 µmol/min/mg), 2% (w/v) (0.03±0.02 µmol/min/mg), and 3% (w/v) (16.69±0.5 µmol/min/mg) of PEG-treated seedlings, respectively. These data show that PEG can be a priming agent to induce defense system at seedling stage of banana, which could enhance their survivability during ex vitro acclimatization.

Aim. The study of possible unintended biochemical peculiarities of newly obtained herbicide-resistant canola (Brassica napus L.) plants expressing the lox-dependent BAR gene was the aim. Methods. Total soluble protein content, total free radical scavenging activity, and superoxide dismutase activity have been investigated using Bradford’s, DPPH, and nitroblue tetrazolium assays, respectively. Fresh weight of plants grown on media with or without phosphinothricin was also measured. Results. The antioxidant activity of leaf extracts of untransformed plants under in vitro growth condi-tions had no significant differences in comparison with ones of phospinothricin-resistant plants in the third generation. No significant changes in parameters investigated were observed in transgenic plants cultivated on media with herbicide addition compared to ones grown on media without it. Fresh weight and total soluble protein content were similar in transgenic and untransformed canola plants under growth without phosphinothricin. Conclusions. Lox-dependent BAR gene introduction and expression resulted in no significant differences in leaf antioxidant activity in transgenic canola plants comparing to untransformed controls.Keywords: Brassica napus, antioxidant activity, DPPH, glufosinate, superoxide dismutase.

Meta-topolin (mT) has been established as an active aromatic cytokinin by Strnad et al. (1997). The present investigation assessed the effects of mT on radish cotyledon growth. The effect of mT on cotyledon growth, chlorophyll, N and soluble protein contents were measured. Peroxidase (POD) activity and polyamine (PA) contents were also determined. Treatment at 0.25, 0.5 and 1.0 mM mT concentrations resulted in 44, 50 and 57% increments in cotyledon growth, respectively, compared with control cotyledons. Increase in chlorophyll content per cotyledon was highest at low mT concentrations. Peroxidase activity was highest at 1.0 mM mT. Soluble protein content was reduced by the application of mT.

ZnO/SnO2/montmorillonite that could flocculate and restrict the growth of Microcystis aeruginosa used as a probe of cyanobacterial was prepared and characterized by means of XRD and TEM. In ZnO/SnO2/montmorillonite, ZnO and SnO2nanoparticles disperse on montmorillonite surface. The determinations of chlorophyll a levels and total soluble protein content demonstrate that ZnO/SnO2/montmorillonite has stronger flocculation effect on Microcystis aeruginosa compared with natural montmorillonit under visible light, and has a good photocatalytic degradation effect on Microcystis aeruginosa under UV irradiation. Under UV, 96.79% removal efficiency is achieved for Microcystis aeruginosa in 1h using 50mg.L-1ZnO/SnO2/montmorillonite. The synergy of absorption flocculation and photocatalysis of ZnO/SnO2/montmorillonite promotes the removal of Microcystis aeruginosa.
