Description:
V návaznosti na naše předchozí články tento příspěvek shrnuje a osvětluje pozoruhodné až rekordní vlastnosti vodních masožravých rostlin bublinatek (Utricularia, Lentibulariaceae) na úrovni ekofyziologické, biofyzikální i molekulárně genetické. Patří mezi ně velice rychlý vrcholový růst prýtu, rekordně vysoká rychlost fotosyntézy a velmi účinná reutilizace N a P ze starých prýtů, ale nikoliv K. Byl prokázán velmi rychlý průběh spuštění pastí, jejich spontánní spouštění bez mechanického podnětu po určité době, rozsáhlé vylučování organických látek do tekutiny pastí k podpoře pasťových mikrobních komenensálů i komplexní regulace tvorby pastí., As a follow-up to our previous papers, this paper summarises and elucidates remarkable and record-breaking eco-physiological, biophysical, and molecular characteristics of aquatic carnivorous bladderworts (Utricularia, Lentibulariaceae). These include the very rapid apical shoot growth, record high photosynthetic rate, and very effective N and P (but not K) reutilization in old shoots. Moreover, an extremely rapid time-course of trap firing, their spontaneous firing without any mechanical stimulus after certain time periods, extensive secretion of organic substances to the trap fluid to support microbial trap commensals, and a complex regulation of trap production are shown and discussed here., and Lubomír Adamec, Dagmara Sirová, Jaroslav Vrba, Jiří Bárta, Jiří Šantrůček, Karel Šimek.

Description:
Australian carnivorous pitcher plant Cephalotus follicularis Labill. produces two types of leaves. During the spring time, the plant produces a foliage type of noncarnivorous leaf called lamina. Later, the second type of leaf is produced - carnivorous pitcher. Using simultaneous measurements of gas exchange and chlorophyll (Chl) fluorescence photosynthetic efficiency of these two distinct forms of leaves were compared. In addition stomatal density, an important component of gas exchange, and Chl concentration were also determined. Pitcher trap had lower net photosynthetic rate (PN) in comparison to noncarnivorous lamina, whereas the rate of respiration (RD) was not significantly different. This was in accordance with lower stomatal density and Chl concentration in the pitcher trap. On the other hand maximum quantum yield of PSII (Fv/Fm) and effective quantum yield of photochemical energy conversion in PSII (ΦPSII) was not significantly different. Nonphotochemical quenching (NPQ) was significantly higher in the lamina at higher irradiance. These data are in accordance with hypothesis that changing the leaf shape in carnivorous plants to make it a better trap generally makes it less efficient at photosynthesis. However, the pitcher of Cephalotus had much higher PN than it was expected from the data set of the genus Nepenthes. Because it is not possible to optimize for contrasting function such as photosynthesis and carnivory, it is hypothesized that Cephalotus pitchers are less elaborated for carnivorous function than the pitchers of Nepenthes. and A.

Description:
Photosynthetic properties of carnivorous plants have not been well characterized and the extent to which photosynthesis contributes to carbon gain in most carnivorous plants is also largely unknown. We investigated the photosynthetic light response in three carnivorous plant species, Drosera rotundifolia L. (sundew; circumpolar and native to northern British Columbia, Canada), Sarracenia leucophylla Rafin. ('pitcher-plant'; S.E. United States), and D. capensis L. (sundew; Cape Peninsula, South Africa), using portable gas-exchange systems to explore the capacity for photosynthetic carbon gain in carnivorous plant species. Maximal photosynthetic rates (1.32-2.22 μmol m-2 s-1 on a leaf area basis) and saturating light intensities (100 to 200 μmol PAR m-2 s-1) were both low in all species and comparable to shade plants. Field or greenhouse-grown D. rotundifolia had the highest rates of photosynthesis among the three species examined. Dark respiration, ranging from -1.44 (S. leucophylla) to -3.32 (D. rotundifolia) μmol m-2 s-1 was high in comparison to photosynthesis in the species examined. Across greenhouse-grown plants, photosynthetic light compensation points scaled with light-saturated photosynthetic rates. An analysis of gas-exchange and growth data for greenhouse-grown D. capensis plants suggests that photosynthesis can account for all plant carbon gain in this species. and B. M. Bruzzese ...
