germplasm name: Vitis riparia pi588259 organism part: ud: 0000001 second order axillary bud cell type: UD:0000001 second order axillary bud development stage: UD:0000003 endodormancy age: 31days after bud break growth media: peat/perlite/soil
Growth protocol
Growth Description: Three to four shoots were trained vertically on spur pruned greenhouse grown vines. Vines were watered two times daily at 8:30 am and 3:00 pm. Environmental Conditions: Vines were grown in greenhouse at 44N latitude for 30 days LD (15H) then received SD treatment (1 day at 13h). Daylight was supplemented with HID lighting (Na halide lamps) to maintain 600 micro mole m-2s-1.

Description
Potted, spur-pruned two to six-year-old vines were removed from cold storage (Seyval on 3/19/2007; V. riparia on 3/26/2007) and grown under a LD (15 h) at 25/20 + 3C day/night temperatures (D/N). When vines reached 12-15 nodes (4/25/2007) they were randomized into two replicated treatment groups, long photoperiod (LD, 15h) or short photoperiod (SD,13h). Five days after this (4/30/2007) the SD (13h, 25/20C) photoperiod treatment was started and LD (15h 25/20C) treatment continued. SD treatment was imposed with automated photoperiod system (VRE Greenhouse Systems). At 1, 3, 7, 14, 21, 28 and 42 days of additional LD or SD, buds were harvested from nodes 3 to 12 from shoot base, immediately frozen in liquid nitrogen, and placed at -80C for future RNA, protein, and metabolite extraction. Three replications (5 vines/replication) were harvested between 05/07-06/07. After bud harvests, the 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.
Data processing
The MAS5.0 Normalization is performed using the justMAS function in the simpleaffy package of Bioconductor (www.bioconductor.org). The target value is 500 for all cases. The code was developed using R2.4.1, Bioconductor 1.9, and simpleaffy 2.8.0. The CDF files were downloaded from the Bioconductor website at http://www.bioconductor.org/packages/release/AffymetrixChip.html. The normalization scripts are available from the PLEXdb team by request.
