The involvement of LHCII-associated polyamines in the response of the photosynthetic apparatus to low temperature

A Review: Polyamines and Photosynthesis

“…Biochemical and physico-chemical measurements showed that the response of the photosynthetic apparatus to low temperature is affected by the changes occurring in the pattern of LHCII-associated Put and Spm which adjust the size of LHCII. The decrease of Put/Spm ratio, mainly due to the reduction in the quantity of LHCII-associated Put led to an increase of the LHCII, especially of the oligomeric forms (Sfakianaki et al, 2006), which is consistent with a data obtained for spinach showed that the low temperature induced a decrease in the Put associated to the thylakoid membranes (He et al, 2002). These results suggest the Put/Spm ratio in the structure of the photosynthetic apparatus associated with the photosynthetic efficiency and the maximal photosynthetic rate, although the mechanism by which polyamines contribute to the increasing tolerance to low temperatures is not yet understood.…”

“…An increase in conjugated Put content can stabilize the thylakoid membrane, thus enhancing resistance of tobacco plants to ozone pollution (Navakoudis et al, 2003) and UV-B radiation (Lütz et al, 2005). Low temperature stress reduced the content of Put as well as the Put/Spm ratio in thylakoids and the light-harvesting complexes LHCII in Phaseolus vulgaris L., leading to a decrease in photosynthetic electron transport rate and inactivation of the PSII reaction center (Sfakianaki et al, 2006). Put is also involved in the induction of a photosynthetic apparatus owning high concentration of reaction center with a small functional antenna that leads to enhance photochemical quenching of the absorbed light energy (Kotzabasis et al, 1999).…”

Polyamines: potent modulators of plant responses to stress

“…PAs conjugation by transglutaminases, especially to Rubisco seems to have significant role in protecting this protein from protease action, thus protecting its photosynthetic efficiency (Serafini-Fracassini et al 1995). Therefore, PAs are likely to play a role in photosynthesis since they are capable of reversing stress-induced damages in photosynthetic apparatus (Sfakianaki et al 2006). Cross-linking of PAs mediated by transglutaminases might play a significant role in polyamine bioactivity for flower development and compatibility in reproduction (Serafini-Fracassini and Del Duca 2008).…”

The exogenous application of spermidine alleviates photosynthetic inhibition and membrane lipid peroxidation under low-light stress in tomato (Lycopersicon esculentum Mill.) seedlings

“…Roychoudhury et al 2011). Indeed, the PAs putrescine (Put), spermidine (Spd), and spermine (Spm) accumulate in plants under abiotic stress conditions, playing an important role in the defence responses to various abiotic stresses (Kumar et al 2006;Bouchereau et al 1999), including metal toxicity (Groppa et al 2003), oxidative stress (Rider et al 2007), drought (Yamaguchi et al 2007), salinity (Demetriou et al 2007;Duan et al 2008), high temperature (Cheng et al 2012), ultraviolet ray (Sfichi et al 2004;Unal et al 2008) and chilling (Shen et al 2000;Sfakianaki et al 2006;Cuevas et al 2008;Zhang et al 2009). However, to our knowledge, it has not been demonstrated to date whether exogenous Spd application can relieve the harmful effects of low-light stress.…”
