Distinct crystalloids were found in chloroplasts of transgenic Pssu-ipt tobacco (Nicotiana tabacum L. cv. Petit Havana SR1) overproducing endogenous cytokinins. They were present both in rooted (T) and grafted (TC) transgenic plants contrary to contr

Accumulation of reduced pheophytin in photosystem II under illumination at low redox potential is known to be accompanied by a pronounced decrease of a chlorophyll fluorescence yield. Simultaneous measurement of this fluorescence quenching and absorb

Anomalies in the ultrastructure of chloroplasts, from transgenic ipt tobacco, overproducing endogenous cytokinins (CKs) were studied. Detailed analyses of CKs and their metabolites showed that Pssu-ipt tobacco contained enhanced contents of CKs both

The photochemical activity of native Central Siberian Scots pine trees (Pinus sylvestris L) was estimated from the middle of February to the middle of March 2001. We measured chlorophyll (Chl) fluorescence in attached intact needles from trees locate

Pigment-depleted Photosystem II reaction centers (PS II-RCs) from a higher plant (pea) containing five chlorophyll a (Chl) per two pheophytin a (Phe), were treated with Chl and several derivatives under exchange conditions [FEBS Lett. 434 (1998) 88].

The light-induced chlorophyll (Chl) fluorescence decline at 77 K was investigated in segments of leaves, isolated thylakoids or Photosystem (PS) II particles. The intensity of chlorophyll fluorescence declines by about 40% upon 16 min of irradiation

Tobacco plants were subjected to long-term CO2 deficit. The stress caused photoinhibition of Photosystem (PS) II photochemistry and the aggregation of the light-harvesting complex of PS II (LHC II). The aggregation was shown by the appearance of the

Pronounced aggregation of the photosystem II light-harvesting complex (LHC II) was observed in low-lightgrown tobacco plants stressed with a strong CO2 deficit for 2–3 days. The LHC II aggregates showed a typical band at 697–700 nm (F699) in low-

Three-year old Norway spruce seedlings (Picea abies L. Karst), were grown in peat soil in a greenhouse and sprayed either with simulated acid mist (a mixture of H 2 SO 4 and HNO 3 , pH 2.7) or with distilled water of pH 5.6 for three months. During s
