BACKGROUND AND OBJECTIVES The objective of this study was to monitor the microorganisms isolated from grapes and its derivative traditional products produced in Iran. MATERIAL AND METHODS Four kinds of grapes cultivated summer of 2010 in vineyard of Takestan and also grape derived products from Shahrod, Hamedan and Takestan were used for this study. The samples were cultured in specific media...

Flavonoids are a group of natural compounds in plants with versatile health benefits for humans. Grapes are a dietary source of flavonoids and the flavonoid components in grape berries can depend on the grape species and cultivar. In this experiment, proanthocyanidins, flavonols, and anthocyanins were analyzed in Vitis coignetiae and V. ficifolia var. ganebu, wild grapes native to Japan, and co...

Table grapes are very popular for their high nutritional and therapeutic value. The objective of this work was to study the effect of table grapes’ quality property in cold chain logistics for improving the transparency and traceability of table grapes’ cold chain logistics and ensuring the table grapes’ quality and safety. Temperature and relative humidity are monitored by adopting the wireles...

In this study, grapes and corresponding wines of Merlot /No 022, 025 and 029/ and Cabernet Franc /No 02, 010 and 012/ clones (recently developed) were evaluated regarding the total phenolic content, total anthocyanin content, and radical scavenging activity, aiming to better understand their quality and market potential. The nineteen individual polyphenols were quantified in studied grape sampl...

The spider Latrodectus hesperus Chamberlin & Ivie (Araneae: Theridiidae) was subjected to low and ultralow oxygen (ULO) treatments at different temperatures. Complete control of the spiders was achieved in 24-h ULO treatments with 0.5% O2 or lower at 1 degrees C and in a 24-h low oxygen (2%) treatment at 15 degrees C. Oxygen level and temperature greatly affected spider mortality. At 1 degrees ...

One of our target genes is a pear pgip cloned in the Labavitch lab (Stotz et al. 1993). PGIPs are proteins containing a leucinerich repeat domain that are targeted to the plant cell wall and that specifically inhibit fungal polygalacturonases (PGs). By inhibiting PGs, PGIPs directly interfere with host cell wall degradation and may thus prevent degradation of pectic oligomeric elicitors that ar...
