| 9 | Dissecting the effect of soil on plant phenology and berry transcriptional plasticity in two Italian grapevine varieties (Vitis vinifera L.).显示文摘Grapevine embodies a fascinating species as regards phenotypic plasticity and genotype-per-environment interactions.The terroir,namely the set of agri-environmental factors to which a variety is subjected,can influence the phenotype at the physiological,molecular,and biochemical level,representing an important phenomenon connected to the typicality of productions.We investigated the determinants of plasticity by conducting a field-experiment where all terroir variables,except soil,were kept as constant as possible.We isolated the effect of soils collected from different areas,on phenology,physiology,and transcriptional responses of skin and flesh of a red and a white variety of great economic value:Corvina and Glera.Molecular results,together with physio-phenological parameters,suggest a specific effect of soil on grapevine plastic response,highlighting a higher transcriptional plasticity of Glera in respect to Corvina and a marked response of skin compared to flesh.Using a novel statistical approach,we identified clusters of plastic genes subjected to the specific influence of soil.These findings could represent an issue of applicative value,posing the basis for targeted agricultural practices to enhance the desired characteristics for any soil/cultivar combination,to improve vineyards management for a better resource usage and to valorize vineyards uniqueness maximizing the terroir-effect. | Alessandro Vannozzi Corrado Perin Fabio Palumbo Marco Sandri Paola Zuccolotto Sara Zenoni Silvia Farinati Gianni Barcaccia Massimo Pindo Paolo Sonego Alessandro Cestaro Margherita Lucchin | 2023 | Horticulture Research2023，10，5： | 0 |
