“…Furthermore, in winter wheat an increased resistance to photo‐inhibition correlated with increased capacity to keep Q oxidized. Similarly in tomato, Q was more oxidized during low‐temperature stress in the more chilling‐tolerant wild tomato Lycopersicon peruvianum (Mill) (Brüggemann et al . 1995).…”

Frost injury in potato can involve the interaction of both freezing temperatures and high light. Thus frosts can result in accumulation of activated oxygen species that change the redox potential of cells. Activated oxygen species can either act as signals that induce protection mechanisms or accelerate injury. In comparison with Solanum tuberosum L., Solanum commersonii Dun., is better adapted to low temperature. In this study the freezing tolerance was studied by isolating the cold-regulated genes glutathione S-transferase ( ScgstF1 ), heat shock cognate 70 kDa ( Schsc70 ) and dehydrin2 ( Scdnh2 ) from S. commersonii and characterizing gene expression in potato genotypes that differ in freezing tolerance. Fluorescence measurements ( F v / F m , 1 ----q P ) showed that photosynthesis of a freezing-tolerant genotype was transiently reduced during frost whereas in S. tuberosum the reduction was higher and irreversible damage occurred. In a freezing-tolerant genotype the transient reduction of photosynthesis occurred coincident with accumulation of ScgstF1 and Scdhn2 transcripts. In cold-acclimated and H 2 O 2 -treated plants, ScgstF1 and Scdhn2 accumulated in freezing-tolerant genotypes whereas Schsc70 transcript was more abundant in S. tuberosum . Pre-treatment with H 2 O 2 also improved the freezing tolerance of S. commersonii suggesting that signal pathways associated with low temperature cold acclimation or H 2 O 2 may overlap.

“…Generally, high-altitude accessions of wild tomato species like Lycopersicon hirsutum, L. chilense and L. peruvianum show a higher level of chilling tolerance, as indicated by a greater post-chilling re-growth capacity, and less severe inhibition in photosynthesis than the cultivated tomato L. esculentum (Brüggemann and Linger, 1994;Jung and Steffen, 1997;Venema et al, 1999). The latter difference is attributed to the higher capacity of the Calvin cycle of wild tomato at suboptimal temperatures, resulting in a more oxidized state of Q A , the primary electron acceptor of PS II (Brüggemann et al, 1995). A recent study elucidated that tomato plants that develop at suboptimal temperatures typically become more tolerant to chill-induced photodamage and show a faster recovery (Venema et al, 2000).…”

“…Similarly, Kicheva et al (1994) in wheat, Kanechi et al (1996) in coffee, and Panković et al (1999) in sunflower observed decreases of in vitro RuBPCO activity under DS. In principle, several factors may contribute to even further declines of RuBPCO activity in vivo through side effects of DS: stromal acidification (Berkowitz et al 1983), increase of stromal ionic strength (Kaiser 1982), or accumulating RuBPCO oxidation through over-excitation, which can play a role under long-term chilling stress (Brüggemann et al 1995). Limitation of RuBP regeneration by the decreased sFBP activity (Table 2) appears unlikely, since the latter enzyme activity still vastly exceeded the P N .…”

The effect of drought stress (DS) on photosynthesis and photosynthesis-related enzyme activities was investigated in F. pringlei (C 3 ), F. floridana (C 3 -C 4 ), F. brownii (C 4 -like), and F. trinervia (C 4 ) species. Stomatal closure was observed in all species, probably being the main cause for the decline in photosynthesis in the C 3 species under ambient conditions. In vitro ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBPCO) and stromal fructose 1,6-bisphosphatase (sFBP) activities were sufficient to interpret the net photosynthetic rates (P N ), but, from the decreases in P N values under high CO 2 (C a = 700 µmol mol -1 ) it is concluded that a decrease in the in vivo rate of the RuBPCO reaction may be an additional limiting factor under DS in the C 3 species. The observed decline in the photosynthesis capacity of the C 3 -C 4 species is suggested to be associated both to in vivo decreases of RuBPCO activity and of the RuBP regeneration rate. The decline of the maximum P N observed in the C 4 -like species under DS was probably attributed to a decrease in maximum RuBPCO activity and/or to decrease of enzyme substrate (RuBP or PEP) regeneration rates. In the C 4 species, the decline of both in vivo photosynthesis and photosynthetic capacity could be due to in vivo inhibition of the phosphoenolpyruvate carboxylase (PEPC) by a twofold increase of the malate concentration observed in mesophyll cell extracts from DS plants.Additional key words: bundle sheath cells; C 3 /C 4 metabolism; CO 2 compensation concentration; malic enzyme; NADP-malate dehydrogenase; phosphoenolpyruvate carboxylase; pyruvate-orthophosphate dikinase; RuBP; RuBPCO; stromal fructose 1,6-bisphosphatase; water potential.
