Physiological and transcriptomic characterization of cold acclimation in endodormant grapevine under different temperature regimes

This study investigates how different temperature regimes affect cold acclimation in endodormant grapevine buds using physiological and transcriptomic analyses.

NYUS.2: an Automated Machine Learning Prediction Model for the Large-scale Real-time Simulation of Grapevine Freezing Tolerance in North America

The paper develops NYUS.2, an automated machine learning model for real-time simulation of grapevine freezing tolerance in North America, outperforming previous models with lower error.

Grapevine scion gene expression is driven by rootstock and environment interaction

The paper investigates how rootstock genotype affects scion gene expression in grapevines under field conditions, finding that this influence is tissue- and time-dependent and interacts with environmental factors.

Development of a new cold hardiness prediction model for grapevine using phased integration of acclimation and deacclimation responses

This paper develops a new cold hardiness prediction model for grapevines, NYUS.1, which outperforms the existing WAUS.2 model by reducing RMSE by up to 37%.

Root system influence on high dimensional leaf phenotypes over the grapevine growing season

The paper examines how rootstock genotype affects leaf phenotypes in grafted grapevines across a growing season, finding subtle but widespread rootstock influence across multiple phenotyping modalities.

Composite modeling of leaf shape across shoots discriminates Vitis species better than individual leaves

The paper models leaf shape changes across shoots in Vitis species and finds composite leaves better predict species identity than individual leaves.

Vein-to-blade ratio is an allometric indicator of climate-induced changes in grapevine leaf size and shape

The paper uses vein-to-blade area ratio as an allometric indicator to show climate impacts on grapevine leaf size and shape across multiple growing seasons.

Characterizing grapevine (Vitis spp.) inflorescence architecture using X-ray imaging: implications for understanding cluster density

The paper uses X-ray imaging and computational methods to analyze grapevine inflorescence architecture across species, identifying traits linked to cluster density and phylogenetic patterns.

X-ray phase contrast imaging of Vitis spp. buds shows freezing pattern and correlation between volume and cold hardiness

The paper uses X-ray phase contrast imaging to study freezing patterns and volume changes in Vitis spp. buds during cold hardiness, finding freezing propagates from center to tip and correlates with volume increase during deacclimation.

Tempo of gene regulation in wild and cultivated Vitis species shows coordination between cold deacclimation and budbreak

The paper compares gene regulation tempo in wild and cultivated grapevines, finding faster deacclimation and budbreak in wild species linked to a coordinated regulon rather than specific gene expression.

Rootstock effects on scion phenotypes in a ‘Chambourcin’ experimental vineyard

This study examines how rootstock affects scion leaf morphology, ion concentrations, and gene expression in Chambourcin grapevines under different irrigation conditions.

Kinetics of winter deacclimation in response to temperature determines dormancy status and explains budbreak in different Vitis species

This study examines how temperature affects deacclimation rates in different Vitis species, linking these rates to dormancy status and budbreak timing.
