“…AtTDX protein (2 mg/mL) was divided into 1 mL aliquots in sterilized of snaplock microtube of 1.7 mL (Axygen, Union City, CA, USA), and the samples were exposed to γ rays at ambient temperature using a high-level cobalt-60 irradiator (point source AECL, IR-79, MDS Nordion International Co., Ltd., Ottawa, ON, Canada) at the Advanced Radiation Technology Institute (ARTI), Korea Atomic Energy Research Institute (KAERI) with absorbed doses ranging from 1 to 80 kGy as previously described [ 31 ].…”

AtTDX, a thioredoxin-like plant-specific protein present in Arabidospis is a thermo-stable and multi-functional enzyme. This enzyme is known to act as a thioredoxin and as a molecular chaperone depending upon its oligomeric status. The present study examines the effects of γ-irradiation on the structural and functional changes of AtTDX. Holdase chaperone activity of AtTDX was increased and reached a maximum at 10 kGy of γ-irradiation and declined subsequently in a dose-dependent manner, together with no effect on foldase chaperone activity. However, thioredoxin activity decreased gradually with increasing irradiation. Electrophoresis and size exclusion chromatography analysis showed that AtTDX had a tendency to form high molecular weight (HMW) complexes after γ-irradiation and γ-ray-induced HMW complexes were tightly associated with a holdase chaperone activity. The hydrophobicity of AtTDX increased with an increase in irradiation dose till 20 kGy and thereafter decreased further. Analysis of the secondary structures of AtTDX using far UV-circular dichroism spectra revealed that the irradiation remarkably increased the exposure of β-sheets and random coils with a dramatic decrease in α-helices and turn elements in a dose-dependent manner. The data of the present study suggest that γ-irradiation may be a useful tool for increasing holdase chaperone activity without adversely affecting foldase chaperone activity of thioredoxin-like proteins.

“…The absorbance of the tannin extract in the pulp was measured with a UV–Vis Spectrophotometer (DU-8600R, Drawell Instrument Comp., Chongqing, China) at a wavelength of 525 nm, and the tannin content was expressed as tannic acid equivalents [ 23 ]. The determination of limonene in the peel was carried out according to the method of Bai et al [ 24 ]. The absorbance of the naringin extract in the pulp was measured with a UV–Vis Spectrophotometer (Drawell DU-8600R) at a wavelength of 283 nm, and the contents of naringin in the pulp were calculated by the standard curve [ 25 ].…”

The quality of Tarocco blood orange (Citrus sinensis (L.) Osbeck), which has been cultivated for many years, has degraded substantially. Decreased sugar content, decreased blood color, and increased sour flavor have developed as a result. To improve fruit quality, we studied the effects of bagging and sodium nitroprusside, as a nitric oxide (NO) donor, on the fruit quality of Tarocco blood orange two months before picking. The results showed that NO treatment effectively improved the content of total soluble solids and limonene in the fruit, as well as the color and hardness of the fruit, but reduced the tannin content. It also increased the contents of soluble sugar, fructose, sucrose, vitamin C, amino acids, and mineral elements. NO treatment inhibited the activities of polygalacturonase and pectin esterase, delayed the degradation of protopectin, and promoted the accumulation of anthocyanins, total flavonoids, and flavonoids synthesis. Thus, NO treatment improved the aroma, flavors, and physical properties of blood orange fruit.

“…Zorn and his group used 2DE coupled with ESI-MS/MS to compare the secretome of Pleurotus sapidus grown in two different growth culture, pea nut shells and glass wool [42]. This study was followed by many proteomics studies analyzing the temperature induced enzyme production for both intercellular (within the mycelium) and extracellular protein (within the cultivation culture) [43] and the effect of stimulatory agent Tween 80 on the mycelium growth and polysaccharide [39] production of Pleurotus tuber-regium, and the effect of extracts derived from two types of asafoetida extracts on mycelium growth in Pleurotus ferulae [44]. Proteomics was also used to analyze Pleurotus tuber-regium cell wall proteins in different mushroom developmental stages [27].…”

Mushrooms are considered an important food for their traditionally famous nutritional and medicinal values, although much information about their potential at the molecular level is unfortunately unknown. Edible mushrooms include fungi that are either collected wild or cultivated. Many important species are difficult to cultivate but attempts have been made with varying degrees of success, with the results showing unsatisfactory economical cultivation methods. Recently, proteomic analysis has been developed as a powerful tool to study the protein content of fungi, particularly basidiomycetes. This mini-review article highlights the contribution of proteomics platforms to the study of edible mushrooms, focusing on the molecular mechanisms involved in developmental stages. This includes extracellular and cytoplasmic effector proteins that have potential or are involved in the synthesis of anticancer, antidiabetic, antioxidant, and antibiotic, in blood pressure control, in the supply of vitamins and minerals, and in other responses to environmental changes. The contribution of different proteomics techniques including classical and more advanced techniques is also highlighted.
