“…Content of chlorophyll b was not affected by the exogenous Put treatments, except that Put-0.5 application significantly decreased content of chlorophyll b. This is in agreement with the result of Unal et al (2008) in Phtyscia semipinnate by additional PAs under UV-A radiation. In fact, chloroplasts themselves enrich a certain amount of PAs including Put, which can benefit formation of chlorophyll, especially chlorophyll a but not chlorophyll b (Shu et al, 2012).…”

Putresince (Put) as one of the important polyamines (PAs) has been identified to regulate mycorrhizal development of citrus plants. The present study was to screen an efficient concentration of Put application at the range of 0.05-1 mM on the trifoliate orange (Poncirus trifoliata) seedlings colonized by Glomus mosseae, in terms of growth, root system architecture, and chlorophyll and carbohydrate contents. Compared to the non-Put treatment, all the Put treatments, especially 0.05 mM Put, significantly increased mycorrhizal colonization of tap root in addition to first, second, and third order lateral roots. The mycorrhizal seedlings treated by 0.05, 0.1, and 1 mM Put showed greater growth (stem diameter, height, leaf number, and fresh mass) and root morphological properties ( tap root length, projected and surface areas, and volume) and higher numbers of first, second, and third order lateral roots. Bio-molecules like chlorophyll a, total chlorophyll, and carotenoid contents of the seedlings were significantly increased by the Put treatments at 0.05-1 mM. All exogenous Put application at the range of 0.05-1 mM significantly decreased sucrose contents but increased glucose contents of leaves and roots. This study suggests that exogenous Put can significantly improve growth performance and root system architecture, besides changes in physiological traits of AMF seedlings. The 0.05 mM concentration of Put showed the best effects.

“…Positive effects of exogenous supplied polyamines on the content of Chla and total Chl in leaves were observed for various stresses, but there were distinct differences in the effect of three main polyamines. Unal et al (2008) found that Chla content was significantly increased in Physcia semipinnata by exogenously added polyamines during exposure to UV-A radiation, and exogenously Spd added samples had higher Chla content than Spm and Put added samples. Spd delayed the loss of Chl more than Spd or Put in detached wheat leaves during dark incubation implying the importance of valency of organic cations (Subhan and Murthy, 2001).…”

“…Investigations into restoration of the maximum photochemical efficiency (Fv/Fm) by adding Put, Spd and Spm to low salt thylakoid showed that Spd are the most efficient ones in Fv/Fm restoration, but higher amounts of Spm and/or Spd reverse the effect and lead to a decline of the Fv/Fm (Ioannidis and Kotzabasis, 2007). When Physcia semipinnata was exposed to UV-A radiation, it was also found that exogenously Spd added samples had higher Chl a content and photosystem II activity than Spm and Put added samples (Unal et al, 2008). In addition, analysis of PSII particles isolated from leaf fragments floated in the presence of Put, Spd and Spm solutions under the dark conditions was conducted.…”

“…moreover, polyamines reverted the effect of diuron on the level of soluble protein almost completely at 24 h of treatment, sPm and PUT was the most effective at 48 h and the effect of only SPM was significant at 72 h in preventing of soluble protein losses. similarly, unal et al [39] reported that exogenously applied sPm samples showed higher protein concentration than other exoge-nously added sPd and Put samples. applications of sPd and sPm were effective in retarding the loss of d1, d2 and cytochrome f from the thylakoid membranes, as well as large rubisco subunits and chlorophyll from the leaf tissue [9].…”

“…applications of sPd and sPm were effective in retarding the loss of d1, d2 and cytochrome f from the thylakoid membranes, as well as large rubisco subunits and chlorophyll from the leaf tissue [9]. it was also reported that PUT, SPD and SPM are associated with light harvesting complex and PS II [27] and polyamines may protect photosystem ii from uv-a radiation [39]. so, polyamines can protect Ps ii against diuron toxicity.…”

the effects of diuron, a photosystem ii inhibiting herbicide, on lipid peroxidation, photosynthetic pigments, soluble protein, proline contents and some antioxidant enzymes in maize leaves were studied and protective effects of polyamines against diuron toxicity were investigated. Diuron significantly increased lipid peroxidation, suggesting oxidative damage in the plants and proline content, while it decreased total chlorophyll, carotenoid and soluble protein levels in the leaves during the experiments. Pretreatment with polyamines statistically decreased lipid peroxidation induced by diuron and spermine (sPm) proved to be the most effective polyamine. Also, pretreatment with polyamines significantly prevented the losses of total chlorophyll, carotenoid and soluble protein induced by diuron. on the other hand, pretreatment with polyamines significantly increased proline contents of the leaves in comparison with the leaves treated with diuron. superoxide dismutase (sod), guaiacol peroxidase (GPX) and glutathione reductase (Gr) activities increased in the leaves treated with diuron while catalase (cat) activity decreased. Pretreatment with spermidine (SPD) did not change significantly SOD activity at 24 and 72 hrs of diuron treatment but prevented the increase in sod activity induced by diuron at 48 h. however, pretreatment with sPd increased GPX activity at 24 h and GR activity at 48 and 72 hrs. CAT activity in the leaves pretreated with SPD was similar to that of the leaves treated with diuron. Pretreatment with sPm prevented the increase in sod activity induced by diuron at 48 h but significantly increased it at 72 h of diuron treatment. However, pretreatment with SPM did not significantly change GPX and GR activities during the experiments but reversed the decrease in CAT activity induced by diuron at 72 h. Pretreatment with putrescine (PUT) prevented the increase in SOD activity induced by diuron at 48 and 72 hrs while it increased GPX and GR activities at 48 h of diuron treatment. Also, the decrease in CAT activity induced by diuron at 72 h was completely prevented by Put. it can be concluded that pretreatment of maize leaves with polyamines reduced the damage produced by diuron and the protective effects of polyamines against diuron toxicity were closely associated with antioxidant system.
