There is provided a channel estimating apparatus and method in a radio communication system. Laminating a pre-laminate sheet comprising a first thermoplastic layer and a first support layer to the sheet of corona discharged treated plastic material. The rotary cover plate is able to be engaged relative to the base thereby enabling the force plate to push the storage media for being electrically connected to the base, or to be opened relative to the base thereby enabling the push plate to push the storage media for being disconnected with the base. In specific embodiments the invention concerns alteration in the gene that encode acid invertase, UDP-glucose pyrophosphorylase, polyphenol oxidase, O-methyl transferase, cinnamyl alcohol dehydrogenase, ACC synthase and ACC oxidase or etr-1 or a homolog of etr-1, and plants having isolated point mutations in such genes. Related structures, drives, and controls are also disclosed.
