Recently, Horticulture Research published online research papers by Professor Xu Qiang's group from the College of Horticulture and Forestry of Huazhong Agricultural University.
Horticulture Research This study combined PacBio sequencing and genetic maps to assemble a high-quality trifoliate genome.
In order to study the influence of Citrus aurantium as a rootstock on scion, the author used Citrus aurantium (Pt) as a rootstock to graft a combination of sweet orange (SWO) scion (SWO/Pt), while using sweet orange rootstock grafting (SWO/SWO) as a control.
The author further found that with the combination of Citrus aurantium as a rootstock, the abundance of 24-nt small RNA in the scion was significantly reduced, while the enzymes related to the synthesis of 24-nt sRNA in the scion did not change significantly.
In summary, this study assembled a high-quality citrus rootstock genome, which provides an important basis for future rootstock genetic improvement research.
Doctoral student Huang Yue and postdoctoral student Xu Yuantao of the College of Horticulture and Forestry of Huazhong Agricultural University are the co-first authors of the paper, and Xu Qiang is the corresponding author of the paper.
