Effects of Rabe1b proteins and heat stress on plastid protein translation. Plastids were isolated from leaves harvested from plants grown under normal conditions (23°C) or after 6 h of heat treatment (45°C). Protein synthesis was assayed in isolated plastids with [³⁵S]Met. The relative levels of protein synthesis were represented by the relative amount of incorporated [³⁵S]Met radioactivity on an equal number of isolated plastids. Means and se were calculated from three replicates. According to Duncan’s multiple range test (P < 0.05), means of the relative amount of incorporated radioactivity in plastid protein synthesis from plants grown at normal conditions (23°C) do not differ significantly if they are indicated with the same lowercase letter; means of incorporated radioactivity in plastids isolated from heat-treated plants (45°C) do not differ significantly if they are indicated with the same uppercase letter.
