Project description:The transition of axillary grapevine buds from paradormancy to endodormancy is an important mechanism for winter survival. Maintenance of paradormancy and transition to endodormancy may be synchronized by factors including phytohormones, genes, transcription factors and other molecular regulators. In the present study we used age matched buds from vines subjected to 28 days of short day (SD; 13h) treatment or continued long day (LD; 15h) photoperiod for high throughput transcriptome profiling.

Project description:Winter season with reduced day length (photoperiod); led to the growth cessation, dormancy induction and cold acclimation in woody perennial plants. To develop an understanding of the photoperiod signal transduction in Vitis riparia; shoot tip transcriptome profiling was performed under differential photoperiod treatments (long (LD, 15h) and short day (SD, 13h)) for 7 or 21 days after shoots reached 10 nodes (LD7, SD7, LD21 or SD21).

Project description:Bud endodormancy induction response of two genotypes (‘Seyval’ a hybrid white wine grape and V. riparia, PI588259 a native north american species) was compared under long (15h) and short (13h) photoperiod. Three separate replicates (5 plants/replicate) were treated to generate paradormant (LD) and same aged endodormancy-induced (SD) buds for transcriptomic, proteomic and metabolomic analysis. Potted, spur-pruned two to six-year-old vines were removed from cold storage (Seyval 3-19-07; V. riparia 3/26/07) and grown under a LD (15 h) at 25/20 + 3C day/night temperatures (D/N). When vines reached 12-15 nodes (3-25-07) they were randomized into LD or SD treatments with 25/20 + 3C D/N in climate controlled greenhouses with automated photoperiod system (VRE Greenhouse Systems). Three replications (5 vines/replication) were harvested between 5/07-6/07 and then again in 5/08-6/08 for a total of six replications. All treatments are repeated at the same time every year and harvested at the same time of day each year to minimize biological noise. At 1, 3, 7, 14, 21, 28 and 42 days of LD and SD treatment, buds were harvested from nodes 3 to 12 of each separate replicate, immediately frozen in liquid nitrogen, and placed at -80C for future RNA, protein and metabolite extraction. These time points encompass early reversible phases as well as key time points during transition to irreversible endodormancy development. After photoperiod treatments and bud harvests, all pruned vines were returned to LD and monitored for bud endodormancy. The endodormant vines were identified after 28 days and moved to cold storage. The nondormant vines were allowed to grow again and induced into dormancy at a later date.
