Exploring salinity induced adaptations in marine diatoms using advanced photonic techniques.

Photonic-based methods are crucial in biology and medicine due to their non-invasive nature, allowing remote measurements without affecting biological specimens. The study of diatoms using advanced photonic methods remains a relatively underexplored area, presenting significant opportunities for pioneering discoveries. This research provides a comprehensive analysis of marine diatoms, specifically Nitzschia sp.

Acclimation Response of Green Microalgae Chlorella Sorokiniana to 2,3',4,4',6-Pentachlorobiphenyl.

The effect of the toxicant 2,3',4,4',6-pentachlorobiphenyl (PCB-119) on the growth, chlorophyll content, and PSII activity of C. sorokiniana cells was investigated. A strong negative effect of the toxicant was observed at PCB concentration of 0.

Effect of thiamethoxam on photosynthetic pigments and primary photosynthetic reactions in two maize genotypes (Zea mays).

Neonicotinoid insecticides are used against the wide range of pests to protect plants. The influence of neonicotinoids on target and non-target insects is well understood. Hence, there are controversial opinions about the effect of neonicotinoids on the plants.

Multiple in vivo Effects of Cadmium on Photosynthetic Electron Transport in Pea Plants.

The inhibitory effects of cadmium (CdSO ) on the primary photosynthetic processes were studied in vivo in Pisum sativum by using Multi-function Plant Efficiency Analyser (M-PEA-2). Photosynthetic parameters related to photosystem (PS) II, PS I and intersystem electron carriers were calculated from the light-induced kinetics of prompt chlorophyll a fluorescence (OJIP transient), delayed chlorophyll a fluorescence (DF), and 820 nm modulated reflection (MR). Low-dose exposure to cadmium (20 μm CdSO for 48 h) reduced probability of electron transfer from plastoquinones to the terminal electron acceptors of PSI (δ ) accompanied by a decrease in the rate of P and PC reduction (V ) and the magnitude of the I step on the DF kinetics.

Chromium effects on photosynthetic electron transport in pea (Pisum sativum L.).

Components of the photosynthetic electron transport chain in pea (Pisum sativum L.) leaves under in vivo conditions showed the following sensitivity to the inhibitory action of chromium(VI): intersystem electron transport > photosystem I > photosystem II. Inhibitory effects of chromium (VI) (KCrO, Cr) on the light reactions of photosynthesis were studied in vivo in Pisum sativum L.
