Figure 2.

Flowering time of progeny from vernalized and unvernalized C24 or antisense plants. The progeny of vernalized and unvernalized plants flowered at the same time, indicating the cold-induced signal for early flowering was not inherited in progeny of the vernalized antisense plants. All plants in the progeny generation responded to a cold treatment by flowering earlier than untreated sibs, confirming that the vernalization signal had been reset. (A) Progeny of vernalized C24 plants. (B) Progeny of unvernalized C24 plants. (C) Progeny of vernalized T3 10.5 antisense plants. (D) Progeny of unvernalized T3 10.5 antisense plants. For A–D, the left graph shows flowering time of plants vernalized in this generation, and the right graph shows flowering time of plants not vernalized in this generation.
