This study aimed to investigate the combined effects of temperature and light conditions on tomato maturation. Tomato fruits that had completed volumetric growth at mature green stage were harvested matured in chambers composed two (daytime–nighttime: 30–20 °C or 20–15 °C) (0 µmol·m−2·s−1 400 µmol·m−2·s−1), which set for 12 h each day night. Our findings indicate ripening was significantly infl...

background heat shock protein 72 (hsp72) is responsible for maintaining critical cellular function during heat stress. hsp72 confers thermotolerance and may play a role in heat acclimation. animal research suggests a difference between sexes in hsp72 expression in response to exercise, however, human data is lacking. conclusion our findings suggest that men and women differ in their cellular st...

Plastid-localized NADPH-dependent thioredoxin reductase C (NTRC) is a unique NTR enzyme containing both reductase and thioredoxin domains in a single polypeptide. Arabidopsis thaliana NTRC knockout lines (ntrc) show retarded growth, especially under short-day (SD) photoperiods. This study identified chloroplast processes that accounted for growth reduction in SD-acclimated ntrc. The strongest r...

The interaction between propranolol (PROP) and human serum albumin (HSA) was studied in the presence of dimethyl methylphosphonate (DMMP). DMMP is usually considered as a simulant for chemical warfare agents (CWAs). For this purpose fluorescence quenching, resonance light scattering (RLS), synchronous, three-dimensional fluorescence spectroscopy and molecular dynamics (MD) simulation were emplo...

The conformational dynamics of wild-type Escherichia coli thioredoxin reductase (TrxR) and the mutant enzyme C138S were studied by ultrafast time-resolved fluorescence of the flavin cofactor in combination with circular dichroism (both in the flavin fingerprint and far-UV regions) and steady-state fluorescence and absorption spectroscopy. The spectroscopic data show two conformational states of...

PURPOSE To study change patterns of 24 h intraocular pressure (IOP) in conscious and freely moving mice using telemetry. METHODS Adult C57BL/6J and CBA/CaJ mice were entrained to a standard 12 h light and 12 h dark cycle. A telemetric pressure transmitter was implanted subcutaneously on the upper back of each light-dark entrained mouse, and the pressure catheter tip was inserted into the vitr...

Blue light has many direct and indirect effects on photosynthesis. The impact of blue light on mesophyll conductance (g(m)), one of the main diffusive limitation to photosynthesis, was investigated in leaves of Nicotiana tabacum and Platanus orientalis, characterized by high and low g(m), respectively. Leaves were exposed to blue light fractions between 0% and 80% of incident light intensity (3...

The influence of photoacclimation on the effects of excessive photosynthetically active (PAR; 400–700 nm) and ultraviolet (UVR; 280–400 nm) radiation was assessed for the marine diatoms Thalassiosira weissflogii (Grunow) Fryxell and Hasle and Thalassiosira antarctica (Comber). Low and high PAR acclimated cultures were subjected to simulated surface irradiance (SSI) that mimicked irradiance arou...

Regulation of the expression of nuclear genes encoding chloroplast proteins allows for metabolic adjustment in response to changing environmental conditions. This regulation is linked to retrograde signals that transmit information on the metabolic state of the chloroplast to the nucleus. Transcripts of several APETALA2/ETHYLENE RESPONSE FACTOR transcription factors (AP2/ERF-TFs) were found to ...
