Changes in growth conditions alter the male strobilus gene expression pattern in Cryptomeria japonica.

abstract：MAIN CONCLUSION:Expression of PAP genes is strongly coordinated and represents a highly selective cell-specific marker associated with the development of chloroplasts in photosynthetically active organs of Arabidopsis seedlings and adult plants. Transcription in plastids of plants depends on the activity of phage-type ...
