Sensitivity of freshwater periphytic diatoms to agricultural herbicides [PDF]
The biomonitoring of pesticide pollution in streams and rivers using algae such as diatoms remains difficult. The responses of diatomcommunities to toxic stress in streamwater are disturbed by the variations of environmental parameters.

Rapid toxicity assessment of six antifouling booster biocides using a microplate-based chlorophyll fluorescence in Undaria pinnatifida gametophytes [PDF]
Biocides of antifouling agents can cause problems in marine ecosystems by damaging to non-target algal species. Aquatic bioassays are important means of assessing the quality of water containing mixtures of contaminants and of providing a safety standard

In detached kohlrabi leaves senescing in the dark, the decrease in chlorophyll to was more pronounced than in chlorophyll a. The retardation by kinetin of the chlorophyll loss was also markedly stronger in the case of chlorophyll b.

Regulation of Leaf Senescence by Cytokinin, Sugars, and Light. Effects on NADH-Dependent Hydroxypyruvate Reductase [PDF]
The aim of this study was to investigate the interactions between cytokinin, sugar repression, and light in the senescence-related decline in photosynthetic enzymes of leaves. In transgenic tobacco (Nicotiana tabacum) plants that induce the production of

Auxin response factor 6A regulates photosynthesis, sugar accumulation, and fruit development in tomato. [PDF]
Auxin response factors (ARFs) are involved in auxin-mediated transcriptional regulation in plants. In this study, we performed functional characterization of SlARF6A in tomato.

Characteristics of C-4 photosynthesis in stems and petioles of C-3 flowering plants [PDF]
Most plants are known as C-3 plants because the first product of photosynthetic CO2 fixation is a three-carbon compound. C-4 plants, which use an alternative pathway in which the first product is a four-carbon compound, have evolved independently many ...

Protoheme Turnover and Chlorophyll Synthesis in Greening Barley Tissue [PDF]
Studies in which (14)C-labeled precursors were fed to etiolated barley leaves (Hordeum vulgare L. var. Proctor) yielded chlorophyll and protoheme having similar specific radioactivities. These findings indicate: (a) there appears to be a rapid turnover of protoheme in the absence of net synthesis; (b) both pigments probably originate from a single 5 ...

Characteristics of the tomato chromoplast revealed by proteomic analysis [PDF]
Chromoplasts are non-photosynthetic specialized plastids that are important in ripening tomato fruit (Solanum lycopersicum) since, among other functions, they are the site of accumulation of coloured compounds.

Properties of synthesis of chlorophyll a from chlorophyll b in cucumber etioplasts.
Chlorophyll a accumulated when chlorophyllide b was incubated with isolated cucumber etioplasts in the dark. When [14C]chlorophyllide b was used as the substrate for chlorophyll synthesis, [14C]chlorophyll a was formed, showing that chlorophyll a was synthesized from the exogenously added chlorophyllide b, not by light-independent reduction of ...
