“…However, phenotypic variations acquired by plant grafting have been observed in a number of studies123456. The issues of how grafting induces phenotypic variations in horticulture plants, and whether the phenotypic variations exhibit heritability remain controversial.…”

Heritability and Reversibility of DNA Methylation Induced by in vitro Grafting between Brassica juncea and B. oleracea

Grafting between tuber mustard and red cabbage produced a chimeric shoot apical meristem (SAM) of TTC, consisting of Layers I and II from Tuber mustard and Layer III from red Cabbage. Phenotypic variations, which mainly showed in leaf shape and SAM, were observed in selfed progenies GSn (GS = grafting-selfing, n = generations) of TTC. Here the heritability of phenotypic variation and its association with DNA methylation changes in GSn were investigated. Variation in leaf shape was found to be stably inherited to GS5, but SAM variation reverted over generations. Subsequent measurement of DNA methylation in GS1 revealed 5.29–6.59% methylation changes compared with tuber mustard (TTT), and 31.58% of these changes were stably transmitted to GS5, but the remainder reverted to the original status over generations, suggesting grafting-induced DNA methylation changes could be both heritable and reversible. Sequence analysis of differentially methylated fragments (DMFs) revealed methylation mainly changed within transposons and exon regions, which further affected the expression of genes, including flowering time- and gibberellin response-related genes. Interestingly, DMFs could match differentially expressed siRNA of GS1, GS3 and GS5, indicating that grafting-induced DNA methylation could be directed by siRNA changes. These results suggest grafting-induced DNA methylation may contribute to phenotypic variations induced by grafting.

“…Grafting technique has been used to increase properties of plants, including fix heterosis, save endangered species, create a quality of a good crop, and regulate size plant [6], control sex differentiation, scatter the seeds and virus free-saplings, set the period of ripeness [7], and determine genetic stability of some clonal variation [8]. Grafting wild durians seedling in indigenous orchards become the important strategy to improve future durian tree productivity [9].It is especially important in Banyuwangi regency.…”

“…Some researchers have claimed that genetic changes may arise due to grafting, but this idea was strongly rejected by Eastern scientists for many decades (Ohta and Chuong, 1975;Taller et al, 1999;Liu, 2006). Genetic effects of the scion on rootstock may lead to tremendous consequences in the breeding of woody plants, where grafting is frequently used.…”

ABSTRACT. Cassava rootstocks of varieties UnB 201 and UnB 122 grafted with scions of Manihot fortalezensis were prepared for anatomic study. The roots were cut, stained with safranin and alcian blue, and examined microscopically, comparing them with sections taken from ungrafted roots. There was a significant decrease in number of pericyclic fibers, vascular vessels and tyloses in rootstocks. They exhibited significant larger vessels. These changes in anatomic structure are a consequence of genetic effects caused by transference of genetic material from scion to rootstock. The same ungrafted species was compared. This is the first report on anatomic changes due to grafting in cassava.
