“…Thus, the present review provides an overview of the current state of the art for grafting woody plants based on several review articles, research articles, and book chapters, each emphasizing a speci c aspect fi of the procedure, such as grafting techniques or the vascular alignment of cambium tissues ( ; ), candidate gene Pina et al, 2012Lima et al, 2017 ), phenolic compounds ( Chen et al, 2017Zarrouk et al, 2010Irisarri et al, 2016Prabpreea et al, 2018 ; ; ), or phytohormones ( ; ).

“…). Auxin and cytokinin response increased at the graft junction during the healing process and this response was specific to the vascular tissues (Yin et al., ; Wang et al., ; Melnyk et al., ). The elevated auxin response appeared at a similar time to the phloem connection, whereas the elevated cytokinin response occurred at a similar time to the xylem connection (Melnyk et al., ).…”

Plant grafting: insights into tissue regeneration

For millennia, people have cut and joined different plants together through a process known as grafting. The severed tissues adhere, the cells divide and the vasculature differentiates through a remarkable process of regeneration between two genetically distinct organisms as they become one. Grafting is becoming increasingly important in horticulture where it provides an efficient means for asexual propagation. Grafting also combines desirable roots and shoots to generate chimeras that are more vigorous, more pathogen resistant and more abiotic stress resistant. Thus, it presents an elegant and efficient way to improve plant productivity in vegetables and trees using traditional techniques. Despite this horticultural importance, we are only beginning to understand how plants regenerate tissues at the graft junction. By understanding grafting better, we can shed light on fundamental regeneration pathways and the basis for self/non‐self recognition. We can also better understand why many plants efficiently graft whereas others cannot, with the goal of improving grafting so as to broaden the range of grafted plants to create even more desirable chimeras. Here, I review the latest findings describing how plants graft and provide insight into future directions in this emerging field.

“…grafted onto P. edulis, P. giberti, and P. mucronata, full differentiation and vascular reconnection took place only at 250 DAG (days after grafting). Interestingly, Wang et al (2014) observed, during grafting in Arabidopsis thaliana (L.) Heynh, that auxin had stimulated the reconnection of the vascular tissues on the third DAG, and that the expression patterns of PIN family genes may have affected the graftunion development by controlling the auxin flow. The hypocotyledonary grafting of P. edulis f. flavicarpa on P. coccinea and P. edulis f. flavicarpa presented, after one month, regenerated vascular tissues and, despite not being exactly juxtaposed, there was reorganization for connection, which did not preclude plant growth (Nogueira Filho et al, 2010a).…”

The mini-grafting is a nondestructive vegetative propagation method based on grafting apical segments onto adult donor plantsderived rootstocks. Here, we aimed at evaluating the mini-grafting of shoot tips derived from adult Passiflora edulis f. flavicarpa plants (yellow passion fruit) onto vegetatively propagated rootstocks of P. mucronata (sandbank passion fruit). Different shoot tip lengths and the fastening material were assayed. A randomized block experimental design was set up following a 2 × 3 factorial scheme [shoots: 8-12 and 3-7 cm × fastening materials (circular clip, "V" shaped clip, and Parafilm ® )] totaling six treatments with four repetitions of eight plants each. The following characteristics were evaluated: graft setting (%); graft and rootstock diameters (mm); graft diameter/rootstock diameter ratio; cellular division in the graft region and starch presence in the graft and rootstock. Parafilm ® provided better adhesion (89.57%) compared to circular (76.03%) and "V" shaped clips (68.74%). The attachment was favored by rootstocks with 8-12 cm shoots (90.27%), compared with those of the 3-7 cm (65.96%). The presence of starch grains in the parenchymatic cells of the graft suggests the translocation of photo-assimilates from physiologically active mature leaves of P. edulis f. flavicarpa to the stem apex. Additionally, the hydrolysis and mobilization of the starch associated and the endogenous auxin levels in this meristematic region may have been responsible for improving the success of the mini-grafting.
