Identification and analyses of genes associated with floral development in Sago palm (Metroxylon sagu)
Flowering process in plants is a complex system and involved various genes. Understandings of the role of genes involved in the flower development enable manipulation of aspects of the process in the future for crop improvement. In this study, efforts have been made to screen for CO and LFY. the gen...

Flowering process in plants is a complex system and involved various genes. Understandings of the role of genes involved in the flower development enable manipulation of aspects of the process in the future for crop improvement. In this study, efforts have been made to screen for CO and LFY. the genes that have been known to be the genes that are activated very early in flowering process. As for the LFYand CO, a few fragments have been successfully isolated and sequenced.
