A diurnal trend of free and bound\nputrescine (F-Put and B-Put, respectively) and TGase activity was observed in\nplants under natural conditions in the forest, with the highest value\ncorresponding to the maximum light intensity and amount of light received\nby the leaves. In another set of experiments, potted Q. ilex plants in\nexperimental fields were subjected to a range of periods of natural\nphotosynthetic photon flux density (PPFD) by covering or not covering the\nwhole trees. Under a natural photoperiod (uncovered leaves), B-Put content\nand TGase activity paralleled the diurnal PPFD pattern, reaching a maximum at\nthe highest PPFD; prior to this maximum, free PAs showed a significant rise.\nPlants that were in darkness until midday and suddenly exposed to high light\nintensity showed enhanced TGase activity, resulting in the maximum\naccumulation of B-Put. The involvement of the accumulation of B-Put reflected\nin the changes of the B-Put/bound spermidine ratio during the photoprotective\nresponses to high light stress in forest plants is discussed in relation to the\nchlorophyll fluorescence parameters observed."@en ; prodottidellaricerca:prodottoDi modulo:ID2619 , istituto:CDS010 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA4422 , unitaDiPersonaleInterno:MATRICOLA8820 . ns11:ID391639 pubblicazioni:rivistaDi prodotto:ID10711 .
