Comparative Transcriptome Analysis Reveals Stem Secondary Growth of Grafted Rosa rugosa 'Rosea' Scion and R. multiflora 'Innermis' Rootstock.

ABSTRACT: Grafted plant is a chimeric organism formed by the connection of scion and rootstock through stems, so stem growth and development become one of the important factors to affect grafted plant state. However, information regarding the molecular responses of stems secondary growth after grafting is limited. A grafted Rosa plant, with R. rugosa 'Rosea' as the scion (Rr_scion) grafted onto R. multiflora 'Innermis' as the stock (Rm_stock), has been shown to significantly improve stem thickness. To elucidate the molecular mechanisms of stem secondary growth in grafted plant, a genome-wide transcription analysis was performed using an RNA sequence (RNA-seq) method between the scion and rootstock. Comparing ungrafted R. rugosa 'Rosea' (Rr) and R. multiflora 'Inner
