Abstract: Salt stress, particularly short-term salt stress, is among the most serious abiotic factors limiting plant survival and growth in China. It has been established that exogenous spermidine (Spd) stimulates plant tolerance to salt stress. The present study utilized two zoysiagrass cultivars commonly grown in China that exhibit either sensitive (cv. Z081) or tolerant (cv. Z057) adaptation capacity to salt stress. The two cultivars were subjected to 200 mM salt stress and treated with different exogenous Spd concen… Show more

“…Hu et al (2012) reported the disturbance of PA homeostasis under short-term salt stress in tomato roots. In general, high Spd and Spm values are considered salt tolerance indices, as demonstrated by Li et al (2016) in salt stress-sensitive and salt stress-resistant zoysiagrass varieties. In a previous study, PA levels changed under salt stress: Put levels decreased and Spd and Spm levels increased in all species examined (Zapata et al, 2004).…”

“…Exogenous Spd application has been shown to enhance the salt tolerance of different plants (Duan et al, 2008). A recent study by Li et al (2016) demonstrated that application of 0.15 mM Spd alleviated the damage caused by salt stress in zoysia ( Zoysia japonica Steud.). Exogenous Spd application also enhanced the salt tolerance of sorghum ( Sorghum bicolor ) seedlings (Yin et al, 2016).…”

“…An earlier study in plants has shown that exogenous polyamine treatment significantly altered endogenous polyamine levels (Sarjala, Häggman, & Aronen, 1997). A recent study also showed exogenous polyamine supplementation increased polyamine biosynthetic enzyme levels in plants (Li, Jin, & Zhang, 2016).…”

“…In the present study, there was one SNP associating with an enzyme (EC:2.5.1.16 -synthase) involved in the metabolism of S-adenosyl-methioninamine -a breakdown substrate of SAM which also participated in the caffeine biosynthesis pathway detected in two pathways (Cysteine and methionine metabolism and Arginine and proline metabolism) (Figure 6.16 -A1 and A2). Similar to caffeine, the breakdown of SAM to S-adenosyl-methioninamine, and to spermidine and spermine was recorded ( Figure 6.16 -A2) while these two compounds have effects on salinity and drought tolerance recorded in a number of crops (Kasukabe et al, 2006;Li et al, 2016;Roychoudhury et al, 2011). Tramontano and Jouve (1997) also found that trigonelline has a role as an osmoregulator in salt-stressed legumes.…”

“…This SNP seems to play an important role in the caffeine synthesis. The second SNP which was also involved in the metabolism (breakdown) of SAM to spermidine and spermine ( Figure 6.9 -A2) while these two compounds have effects on salinity and drought tolerance recorded in a number of crops (Kasukabe et al, 2006;Li et al, 2016;Roychoudhury et al, 2011). The SNP located in chromosome 11 at 30,965,526 with more C-alleles and less A-alleles in B1 than in B2 (56% vs 30% and 44% vs 70%, respectively) resulting in the change of amino acid from mainly alanine to mainly serine (Appendix table S6.7).…”
