Comprehensive transcriptome analysis of grafting onto Artemisia scoparia W. to affect the aphid resistance of chrysanthemum (Chrysanthemum morifolium T. )

Abstract Aphid ( Macrosiphoniella sanbourni ) stress drastically influences the yield and quality of chrysanthemum, and grafting has been widely used to improve tolerance to biotic and abiotic stresses. However, the effect of grafting on the resistance of chrysanthemum to aphids remains unclear. Therefore, we used the RNA-Seq platform to perform a de novo transcriptome assembly to analyze the self - rooted grafted chrysanthemum ( Chrysanthemum morifolium 'Hangbaiju') and the grafted Artermisia-chrysanthemum ( grafted onto Artemisia scoparia ) transcription response to aphid stress.
