“…2, 3), suggesting that salt priming strengthened salt tolerance in sweet sorghum. This finding conformed to the studies on maize, sorghum, mung bean and rice (Amzallag et al 1990;Djanaguiraman et al 2006;Saha et al 2012;Tajdoost et al 2007), but the mechanisms of salt priming were systematically explored in terms of ionic toxicity, osmotic adjustment and antioxidant ability in this study.…”

“…3d, 6a). Therefore, salt-induced ionic toxicity in sweet sorghum was attenuated by salt priming, and this common finding also has been evidenced in other crops (Djanaguiraman et al 2006;Saha et al 2012). However, we further demonstrated that salt priming restricted Na ?…”

“…As well known, salt priming can availably improve plant tolerance to salt stress (Amzallag et al 1990;Djanaguiraman et al 2006;Saha et al 2010Saha et al , 2012Tajdoost et al 2007;Tanou et al 2012;Umezawa et al 2000). Salt stress inhibits photosynthetic activity and reduces plant growth by inducing osmotic stress and ionic toxicity (Chaves et al 2009;Tari et al 2013).…”

“…Salt priming can help plants acclimate to lethal salinity by enhancing osmotic adjustment and suppressing ionic toxicity, indicated by the lowered Na ? concentration and increased accumulation of osmolytes in salt-pretreated plants (Djanaguiraman et al 2006;Saha et al 2012). Salt stress increases the concentration of toxic ions in plant cells, causes ion homeostasis disruption and then results in oxidative damage with excess generation of reactive oxygen species (ROS) (Zhu 2003).…”

This study attempted to explore how salt priming affected salt tolerance in sweet sorghum with emphasis on root Na ? uptake. After 10 days of pretreatment with 150 mM NaCl, plants were stressed with 300 mM NaCl. After salt stress for 7 days, dry matter of root and shoot decreased by 58.7 and 69.7 % in non-pretreated plants and by 37.9 and 41.3 % in pretreated plants. Consistently, pretreated plants maintained higher photosynthetic rate during salt stress, suggesting the enhanced tolerance by salt priming. Salt priming enhanced osmotic resistance, as proline and relative water contents in the leaf were higher in pretreated plants under salt stress. Salt priming alleviated salt-induced oxidative damage not by improving antioxidant protection due to lower increase in leaf malondialdehyde content and no extra induction on ascorbate peroxidase, catalase, superoxide dismutase, ascorbic acid and reduced glutathione in pretreated plants. After 7 days of salt stress, root Na ? efflux increased by 8.5-and 3.9-folds in pretreated and non-pretreated plants, suggesting that salt priming reduced root Na ? uptake, and then root and leaf Na ? accumulation were mitigated in pretreated plants. However, root Na ? extrusion became indifferent between pretreated and non-pretreated plants under salt stress after inhibiting plasma membrane (PM) Na ?

“…Eco-physiological methods seem more convenient and easier to be applied in agricultural practice, in contrast to genetic engineering and conventional breeding (Yan et al 2013c;Guerrero et al 2014). For example, salt pretreatment with sublethal level of salinity has been evidenced as an available way for enhancing crop salt tolerance (Amzallag et al 1990;Umezawa et al 2000;Djanaguiraman et al 2006;Tajdoost et al 2007;Saha et al 2012).…”

Sweet sorghum is an important energy crop. This study aimed to investigate the effects of salt pretreatment on the interaction between photosystem II (PSII) and photosystem I (PSI) upon salt stress. In this study, sweet sorghum was pretreated with 150 mM NaCl for 10 days, and subsequently, the pretreated plants were subjected to severe salt stress at 300 mM NaCl. PSII and PSI photoinhibition occurred in non-pretreated plants after 4 days of salt stress, as the maximum quantum yield of PSII (Fv/Fm) and the maximal photochemical capacity of PSI (4MR/MR 0 ) significantly decreased, and their normal coordination was destroyed. The significant positive correlation between Fv/Fm and 4MR/MR 0 under salt stress indicated that PSII photoinhibition was in relation to PSI photoinhibition, and PSI photoinhibition might lead to PSII photoinhibition through inhibiting electron transport at the acceptor side of PSII. Salt stress did not induce PSII photoinhibition in salt-pretreated plants, and thus, salt pretreatment protected PSI against photoinhibition not by aggravating PSII photoinhibition. Salt pretreatment mitigated the decrease in CO 2 assimilation, reduced the feedback inhibition on photosynthetic electron transport and then contributed to suppressing PSI and PSII photoinhibition in sweet sorghum under salt stress. Therefore, the normal coordination between PSII and PSI was maintained in salt-pretreated plants. In conclusion, salt pretreatment ensured normal PSII and PSI coordination by preventing photoinhibition in sweet sorghum under salt stress.
