“…No induction of any new isoenzymes was observed in the esterase profile of Sakha 104 cultivar under salinity compared with control. These results agreed with those reported by Hassanein (1999) who stated that Salinity increases EST isozymes, the highest numbers of esterase isoenzymes were detected under the highest NaCl concentration. Rashed et al (1994) observed differences in the intensities in esterase bands between salt tolerant and salt sensitive genotypes of maize and wheat.…”

A new protein bands and Esterase banding pattern could be used as a biochemical marker for selecting tolerant rice cultivars to be grown under salt conditions, and, treatment rice seed with ascorbic and salicylic acids greatly alleviate the harmful effect of salt stress on rice plant. In this study, three ric cultivars (Giza 177, Sakha 103 and Sakha 104) were selected to determine the interactive effects of salinity (0.4 and 10 ds/m) ,ascorbic and salicylic acids on Esterase isoenzymes , pattern protein synthesis and seed vigor. Laboratory experiment was conducted at Seed Technology Research Department during 2010 year. The results revealed that one new band (Est 3 isoenzyme) was detected of both Giza 177 and Sakha 103 cultivars (untreated seed) under salt stress. Salinity treatments induced synthetic 3 and 2 new protein bands of Giza 177 and Sakha 103 (untreated seed), respectively. No new bands were obtained of Sakha 104 (untreated seed). Protein with molecular weight of 49 KD could play an important role in triggering a system to tolerate sever stress of salinity. Treatments of seeds of Giza 177 and Sakha 103 cultivars with salicylic or ascorbic acid induced one Esterase3 isoenzymes (RF 0.9). Three unique bands were observed under salinity with molecular weight 86, 93 and 132 KD of (Giza 177 + salicylic), (Sakha 103 +Ascorbic) and (Sakha 104+Ascorbic), respectively. It could be summarized that only under saline conditions, Pre-sowing rice seed of Sakha 104 cultivar with Ascorbic produced the highest germination percentage, speed germination index, germination rate and seedling dry weight and the lowest mean germination time as well as time 50 % germinated seed compared with other two cultivars under study.

“…Results reported herein showed that osmotin protein with molecular weight 32 KDa was highly expressed in 10 dS/m of NaCl stressed callus. Results were in line with Hassanein, (1999) who reported that proteins with MW 127 and 52kDa highly induced in peanut under NaCl stress. Also, Kumar et al, (2008) found that protein bands with MW 98, 69, 66 and 64 kDa were highly expressed in NaCl treated callus of Jatropha curcas while other bands with MW as 83, 58 and 43 kDa proteins were low expressed.…”

The effect of different concentrations of NaCl (6, 8 and 10 dS/m) on growth and alkaloids production in 21 days-old callus of Egyptian henbane (Hyoscyamus muticus L.) was studied. Results showed that 10 dS/m of NaCl increased fresh and dry weight by 4.1 and 2.8 fold more than control, respectively. Total alkaloids increased by 2 fold at 10 dS/m compared to control or wild leaves. In contrary, wild leaves had the highest amount of hyoscyamine (2.8 mg/g DW) followed by 6 dS/m stressed-callus (1.14 mg/g DW) as detected by HPTLC. Peroxidase and superoxide dismutase activity were increased by 2.6 and 2.3 fold, respectively in highly salt stressed callus than control while catalase activity (CAT) was decreased. Anthocyanin concentration was increased 3 fold in 10 dS/m of NaCl stressed callus compared to control. Glutathione content was increased by 33.8% under low level of NaCl more than control. Reduction of photosynthetic pigments under all NaCl levels led to decrease the total carbohydrate and protein content. Protein band with molecular weight 109 KDa was a unique band in 10dS/m of NaCl treated callus with high expression of protein bands with MW 44, 38 and 32 KDa. Histologically, callus cells under high level of NaCl had amoeboid shape and start in senescence with formation of lysiogenous intercellular spaces. It can be concluded that, using of NaCl as elicitor was effective method for enhancing the growth and alkaloids

“…Eğer ilgili enzimler oksidatif reaksiyonları kontrol altında tutamazsa, lipidlerin oksidasyonu bazı ürünlerin oluşmasına yol açmakta ve bu ürünler de protein ve DNA moleküllerinde yapısal hasarlara neden olmaktadır [124]. Arachis hypogea bitkisinde 45 mM' a kadar olan tuz uygulamalarının lipid miktarını artırdığı, daha yüksek tuz konsantrasyonlarının ise azalttığı belirlenmiştir [125]. Wu ve arkadaşları (1998), tuz stresi altındaki Spartina patens bitkisinin kök hücre membranlarındaki lipid kompozisyonundaki değişimleri araştırmış; artan tuz konsantrasyonları sonucunda sterol ve fosfolipid miktarının azaldığını, sterol/fosfolipid oranının ise değişmediğini gözlemlemişlerdir [126].…”

Tuz stresi dünyada tarımsal verimliliği kısıtlayan en önemli abiyotik stres faktörlerinden biridir. Toprak tuzluluğu bitkiler de fotosentetik pigment miktarını ve fotosentetik aktiviteyi, sonuçta da büyüme hızını azaltabilmektedir. Ancak bazı bitki türleri tuza toleranslıdır ve yüksek tuz konsantrasyonlarında yaşam döngülerini tamamlayabilir. Tuza toleranslı bitkiler çözünür karbohidratlar, çözünür proteinler, bazı amino asitler, kuaterner amonyum bileşikleri ve polioller gibi bazı organik bileşikleri dokularında biriktirebilir. Bu organik bileşikler tuza toleranslı bitkilerde su kaybını minimum seviyeye indirmekten, hücresel ozmoregülasyonun sağlanmasından ve aktif oksijen türlerinin detoksifikasyonundan sorumludur. Tuz stresi aynı zamanda bitkilerde aktif oksijen türlerinin oluşum hızını artırarak oksidatif strese neden olabilir. Bu durumda tuza toleranslı bitkilerin etkili bir antioksidant sisteme sahip olması gerekir. Bu derlemede, tuz stresi altındaki bitkilerde meydana gelen bazı fizyolojik ve biyokimyasal değişimlerle tuz toleransı arasındaki ilişki tartışılmıştır.
