Abstract

Quantitative and electrophoretic patterns of leaf SOLUBLE PROTEINS of canola (Brassica napus L.) winter (cv. Symbol) and spring (cv. Hyola 401) cultivars were assessed in response to a VERNALIZATION TEMPERATURe (4°C). Seeds were grown in a growth chamber at 15/10ºC (day/night), with 140 W m-2 light density and 16/8 h photoperiod. Control plants were grown continuously in these conditions until day 56. On day 30 (4th fully expanded leafy stage), cold treated seedlings were transferred to 4°C, followed by transfer to original conditions. Seedlings were sampled every 48 h for leaf fresh weight measurements. SOLUBLE PROTEINS were extracted from the leaves, and their amounts were measured, using spectrophotometery. Proteins data were analysed as 3-factorial experiment on the basis of completely random design (CRD): cultivar (2 levels), temperature (2 levels), and sampling time (14 levels) in 3 replications. Then, 45 µg of proteins was loaded on SDS-PAGE gel with 15% density. ANOVA results showed that all main effects and their interactions were highly significant. Temperature alterations showed no substantial effects on proteins amount in the cold-treated leaves of spring canola but, considerable accumulation of proteins was recognized in those of winter canola. This accumulation was detected from 8 day at 4°.Ccontinuing until 2 day of transfer from cold to the 15°C-conditions (day 54) in the winter cultivar. In the latter cultivar, the 2-week cold-treated seedlings (day 44) produced a new 47.7 kDa cold-induced polypeptide in their leaves compared with the controls: such response was identified 2 d later in the cold-treated seedlings of spring cultivar. This pattern was lasted until 18 d at 4°C (day 48) in the leaves of both cultivars but, after the return to 15°C, it disappeared in the spring earlier than the winter canola. Moreover, changes in the intensity of some protein patterns were distinguished in both cultivars at 4°C compared with those in the controls.
