It is really true as you mention that the details of methods is needed. But considering that this method is also expressed in thus way in our previous articles (Ren L, et al (2021) Genome-Wide Identification of TCP Transcription Factors Family in Sweet Potato Reveals Significant Roles of miR319-Targeted TCPs in Leaf Anatomical Morphology. Front. Plant Sci. 12: 686698. doi: 10.3389/fpls.2021.686698), we just cite the original source here.
Pg 3 Plasmid and sweet potato genetic transformation section: Include relevant protocols instead of just referring to another manuscript. Citing the original source is required but so are details needed to reproduce and evaluate the soundness of the manuscript. The same applies to other parts of the materials and methods:
