Turkish Journal of Agriculture and Forestry
This study was conducted to determine the effects of different drying methods and cold storage treatments on the postharvest quality and nutritional properties of P. ostreatus mushroom. In the study, six different treatments including natural drying, oven drying (60 °C), microwave drying (450 W), storage at -18 °C, 4 °C and 10 °C were evaluated. After drying and cold storage, pH value, ash, protein, color, total phenolic content, total flavonoid content, antioxidant activity and element contents in mushroom samples were detected. According to findings obtained from the study, drying and cold storage treatments significantly (p < 0.01) affected the postharvest quality and nutritional composition of P. ostreatus. The protein content, ash content, L* color value, total phenolic content, total flavonoid content, antioxidant activity and essential mineral contents such as potassium, magnesium, phosphorus, calcium, iron, zinc, and manganese of P. ostreatus decreased after drying and cold storage compared to the fresh mushroom sample. As a result, the best treatment was determined as storage at 4 °C in terms of protection the quality and nutritional value of P. ostreatus during postharvest storage. In addition, natural drying was the most effective treatment among drying methods, and it can be used successfully for longterm storage of this mushroom. However, it was concluded that microwave drying method was not suitable for the preservation of P. ostreatus since it caused significant nutrient and quality losses. The results of the present study will provide useful information about postharvest preservation and processing of P. ostreatus for researchers working on this issue.

The research aimed to assess the effects of methyl jasmonate (0.25, 0.5, and 1.0 mM MeJA) on weight loss and phytochemical compounds of kiwifruit (Actinidia deliciosa cv. `Hayward') throughout the cold storage and shelf life. Kiwifruits were stored at 0 ± 0.5 °C and 90 ± 5% RH for 180 days, and at 20 ± 1.0 °C and 80 ± 5% RH for 5 days in shelf life conditions. During cold storage, weight loss was significantly lower (P < 0.05) in 0.25 and 1.0 mM MeJA treatments than those of control and 0.5 mM MeJA treatments. The highest flesh firmness was determined in MeJA-treated fruits. In the latest measurement period of cold storage and shelf life, the lowest respiration rate was obtained from 0.5 and 1.0 mM MeJA treatments. MeJA-treated fruits had significantly higher hue angle at the end of cold storage. Generally, in shelf life analysis, acidity of MeJA-treated fruits was significantly lower than that of control fruits. At the end of cold storage, the highest vitamin C, total flavonoids, and antioxidant activity (DPPH) were measured in 1.0 mM MeJA treatment, whereas the highest total phenolics were detected in 0.25 mM MeJA treatment. Present findings revealed that MeJA could be used as an effective postharvest tool to maintain flesh firmness and phytochemical compounds of kiwifruits.

Herein, the effects of roasting levels (rare, medium, and well) on the fatty acid composition, oil and polycyclic aromatic hydrocarbon (PAH) contents of various dried nuts (almonds, hazelnuts, peanuts, and cashews) were investigated. The roasting level affected the moisture and total oil contents, as well as the fatty acid composition. The roasting level had no significant effect (P > 0.05) on saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) contents of the dried nuts, while it had a significant effect (P < 0.05) on polyunsaturated fatty acid (PUFA). In raw and dry roasted nut, the most common SFA, MUFA, and PUFA were palmitic, oleic, and linoleic acid, respectively. The amounts of linoleic acid and ΣPUFA, as well as ΣPUFA/ΣSFA ratio were the lowest in the well roasted samples. Additionally, the types of dried nut had a significant effect (P < 0.01) on the amounts of total oil and fatty acid compositions. The highest total oil amount (62.15%) was found in hazelnuts, while the lowest PUFA content (7.54%) was also determined in hazelnuts. From the nutritional perspective of view, the highest ΣPUFA / ΣSFA ratio (2.40) belonged to almonds. Although the recovery rates of PAH standards varied between 70.14%-85.10%, none of the heavy PAH compounds could be detected in raw and roasted samples.

Tomato (Solanum lycopersicum) is the second most important horticultural crop worldwide that is widely used as a model plant in genetic manipulation of Solanaceae. CRISPR/Cas9 system has been successfully utilized in several studies for genome edition of model tomato cultivars. However, these genome editing systems should be also optimized for commercial tomato cultivar for direct application of genome editing in field conditions. In this study, we have optimized an Agrobacterium-mediated gene transfer and regeneration system for CRISPR/Cas9 genome editing in two commercial tomato cultivars for the first time. The effect of explant type, genotype, pre-transformation time, Agrobacterium concentration, infection time, …
