Integrated transcriptomic and metabolic analysis reveal the mechanism controlling cucumber-pumpkin grafting compatibility.

ABSTRACT:

Background

The most widely used rootstock of cucumber grafting is pumpkin (Cucurbita moschata). The main task of pumpkin rootstock breeding is to evaluate its compatibility with cucumber scions. One of the main factors affecting grafting compatibility is the rootstock bleeding sap, which affects the wound healing of graft junction.

Results

We evaluated the grafting affinity of 30 pumpkin rootstocks, which were F1 hybrids derived from 56 breeding lines, by grafting them with the cucumber scion FH8. Correlation analysis of grafting compatibility with phenotypic traits of rootstock seedlings, grafted plants, and biochemical characteristics of rootstock bleeding sap highlighted the positive role of soluble solids content and the negative role of the absorbance of bleeding sapsme
