Quality Evolution of Turpan Dry Red Wine During Aging Under Controlled Micro-Oxygenation.

During the aging process, oxygen regulation was applied to Cabernet Sauvignon dry red wine (CSDRW) from the Turpan region. Through physicochemical analysis, headspace solid-phase microextraction and gas chromatography-mass spectrometry (HS-SPME-GC-MS), combined with differential significance analysis and sensory evaluation, this study analyzed the effects of different oxygen concentrations on the quality of Cabernet Sauvignon dry red wine from Turpan. The results indicated that oxygen regulation facilitated the polymerization of phenolic substances, enhanced color intensity, and reduced the content of total sulfur and anthocyanins.

Transcriptome and coexpression network analysis reveals properties and candidate genes associated with grape ( L.) heat tolerance.

Temperature is one of the most important environmental factors affecting grape season growth and geographical distribution. With global warming and the increasing occurrence of extreme high-temperature weather, the impact of high temperatures on grape production has intensified. Therefore, identifying the molecular regulatory networks and key genes involved in grape heat tolerance is crucial for improving the resistance of grapes and promoting sustainable development in grape production.
