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 ...

Ionizing radiation (IR) causes oxidative stress through overwhelming generation of reactive oxygen species (ROS) in the living cells leading the oxidative damage further to biomolecules. Grapevine (Vitis vinifera L.) posses several bioactive phytochemicals and is the richest source of antioxidants. In this study, we investigated V. vinifera for its phytochemical content, enzymes profile and, RO...

The color of grapevine berries is one the most important quality parameters that define appearance, attracts consumer, and determines price, especially in red grape cultivars. Some varieties show less development due to many factors such as temperature, light intensity, agricultural management. present study aimed evaluate diverse phytohormones coupled with grafting on fruit coloration ’Crimson...

Abstract Grapevine powdery mildew is caused by Erysiphe necator that seriously harms grape production in the world. Stilbene synthase makes phytoalexins contribute to resistance of grapevine against mildew. A novel VqNSTS3 was identified and cloned from Chinese wild Vitis quinquangularis accession Danfeng-2. Novel transferred into susceptible ‘Thompson Seedless’ Agrobacterium-mediated transform...
