Transcriptional expression of different grafting combinations during healing

Grafting was widely used in pear cultivation as an ancient cultivation technique, the use of rootstocks could improve the resistance of pear trees, make pear trees early fruit. The healing process of plant grafting involves complex signal transduction and material accumulation.We used two different grafting combinations, include ‘Qingzhen D1’ on ‘QAUP-1’ and ‘Qingzhen D1’ on ‘Qingzhen D1’.The samples which are the part of graft union of those two combinations were collected om 1 day, 5 days , 9 days and 30 days after grafting. We performed an in-depth RNA-seq analysis to observe the transcriptional changes that occur during the development of two combinations. Transcriptional analysis of two grafting combinations which are‘Qingzhen D1’ on ‘QAUP-1’ and ‘Qingzhen D1’ on ‘Qingzhen D1’ on four stages during the grafting healing process.
