[Objective]The clone and the expression analysis of the full length sequence of LiliumS-RNase gene which would made a foundation for discovering the molecular regulation of incompatibility in Lilium.[Methods]The full cDNA sequence of S-RNase was isolated from a style of Lilium oriental‘Justina'by RACE.Semi-quantitative RT-PCR technology was used to analyse the expression of different organs of the S-RNase gene in the same period.Bioinformatic analysis was used by the online tools of National Center for Biot...
