We report the possibility to modify wetting properties of surfaces a diversity seeds including: lentils (Lens culinaris), beans (Phaseolus vulgaris) and wheat (Triticum, species C9) by cold radiofrequency air plasma treatment. Air treatment leads dramatic decrease in apparent contact angle. Moreover, speed germination yield (germination rate) can be modified preliminary The change is at least partially due oxidation their surface under Significant growth peaks corresponding nitrogen...
We elucidate grapevine evolution and domestication histories with 3525 cultivated wild accessions worldwide. In the Pleistocene, harsh climate drove separation of grape ecotypes caused by continuous habitat fragmentation. Then, occurred concurrently about 11,000 years ago in Western Asia Caucasus to yield table wine grapevines. The domesticates dispersed into Europe early farmers, introgressed ancient western ecotypes, subsequently diversified along human migration trails muscat unique...

Continually increasing global temperature could severely affect grape berry metabolite accumulation and ultimately wine polyphenol concentration color intensity. To explore the effect of late shoot pruning on composition, field trials were carried out Vitis vinifera cv. Malbec Syrah grafted 110 Richter rootstock. Fifty-one metabolites detected unequivocally annotated employing UPLC-MS based profiling. Integrating data using hierarchical clustering showed a significant treatments must...
Recent global climatic changes have highlighted viticulture in arid/semiarid regions as an increasingly relevant study model. Grapes arid face excessive solar irradiance, leading to more than 50 °C berry surface temperatures exposed berries. The resultant oxidative stress, sunburn necrosis, and browning consistently reduce quality. Adapting adequate training system the climate cultivar is a simple inexpensive method control radiation regime. This compares wine characteristics compositional...

Grapevine (Vitis vinifera L.) is one of the classical fruits Old World. Among thousands domesticated grapevine varieties and variable wild sylvestris populations, range variation in pip morphology very wide. In this study we scanned representative samples grape an attempt to probe possibility using 3D tool for variety identification. The scanning was followed by mathematical statistical analysis innovative algorithms from field computer sciences. Using selected Fourier coefficients, a clear...
Global climate change and the expected increase in temperature are altering relationship between geography grapevine ( V. vinifera ) varietal performance, implications of which yet to be fully understood. We investigated berry phenology biochemistry 30 cultivars, 20 red 10 white, across three seasons (2017–2019) response a consistent average difference 1.5°C during growing season two experimental sites. The experiments were conducted at Ramat Negev (RN) Ramon (MR) vineyards, located desert,...
Societal Impact Statement Grapevine is a major horticultural crop that has been intertwined with human culture for Millennia. The Levant was an important center of the ancient winemaking industry until collapse Byzantine Empire. Consequently, identity grapevine varieties considered lost. Here, we study domestication history Levantine samples using whole‐genome sequencing data and show some are authentic descendants they conform to independent lineage. This precious germplasm paves route...
The grapevine is an economically important plant, with a historical connection to the development of human culture. Currently, over 6000 accessions are known as individual varieties, some which national heritage, valuable for current viticultural practices, and genetic resources maintain plasticity under changing climatic conditions, environmental sustainability, market demands. Recently, diversity cultivated grapevines has declined significantly, due increased focus global wine industries...

Dittrichia viscosa is a perennial Mediterranean plant used in traditional medicine for "calming purposes", pointing at possible antidepressant activity of the plant. We conducted chromatographic and bioassay-guided fractionation D. root extract to isolate specific fraction (fraction "K") with antidepressant-like characteristics vivo strong antioxidant properties vitro. A single dose "K" reduced immobility time forced swim test mouse model possessing depressive-like phenotype. Neurochemical...
Grapevine (Vitis vinifera L.) currently includes thousands of cultivars. Discrimination between these varieties, historically done by ampelography, is in recent decades mostly genetic analysis. However, when aiming to identify archaeobotanical remains, which are charred with extremely low genomic preservation, the application approach rarely successful. As a result, variety-level identification most grape remains prevented. Because pips highly polymorphic, several attempts were made utilize...
Prenatal stress may increase concentrations of maternal glucocorticoids, which restrict fetal growth, with variable impact upon postnatal development. Among key regulators hormone effects are the glucocorticoid receptor (GR) and 11β-hydroxysteroid dehydrogenase-2 (11βHSD2), enzyme that inactivates glucocorticoid. This study utilized mice selectively bred for social dominance (Dom) or submissiveness (Sub), respectively exhibiting resilience sensitivity to stress, test whether stress-induced...
‘Malbec’ grapevines commonly have high yield, thus intermittently negatively affecting wine quality parameters. Here, we describe the use of late shoot pruning (LSP) practice applied for improvement. We examined effect timing LSP on vines grown in Mediterranean conditions during three consecutive seasons (2016–2018) Israel. The treatment applications (applied one, two and weeks after bud break) were compared with cluster-thinned, winter-pruned (WP + T) standard winter (WP). postponed break...
In semi-arid areas, vineyards grown for winemaking are usually mildly irrigated by drip irrigation systems in a manner maintaining drought stress.
