“…Cytokinin enhances the regulation and distribution of PIN proteins, favoring the transport of auxins between callus cells during the formation of vascular bundles. Bidabadi et al (2018) obtained satisfactory quality in grafting callogenesis for a formulation based on ANA and BAP, with a simultaneous increase in the concentration of antioxidant enzymes (catalase, peroxidases, and ascorbate peroxidase) and less accumulation of H 2 O 2 in the tissues of the graft union.…”

The use of growth regulators (GRs) in a mechanized bench grafting system is essential for the final quality of grafted grapevine plants. In Brazil, the GRs used (commercial waxes) are imported, increasing the production cost for nurseries. This work aimed to test the in vitro callus co-cultivation technique as a strategy for prospecting effective doses and mixtures of GRs for in vivo graft union on grapevines. Two genotypes were used as scions (‘Bordo’ and ‘Riesling Italico’) and two as rootstocks (‘SO4’ and ‘P1103’). Callus from different scion/rootstock combinations were co-cultivated, varying the doses (0.25 to 20 mg l-1) of auxins (DBA, IAA and IBA) and cytokinin (BAP), following the Doehlert design. The best in vitro treatments were validated in vivo, in plants grafted with an ‘omega’ cutter machine. Multivariate and non-parametric methods were applied to integrate the results. In vitro prospecting combined with the in vivo validation strategy allowed us to select effectively the IAA(2.50 mg l-1) plus BAP(1.00 mg l-1) formulation with the potential to induce graft callus union similar to commercial waxes. The induction intensity varied among the genetic combinations but was similar in the in vitro and in vivo conditions.

“…For grapevine (Vitis vinifera) grafting, exogenous application of benzyladenine (BA) or kinetin (Ki) on the graft partners significantly enhanced callus formation and graft survival rates [9]. Another study conducted on grapevine showed that dipping the graft partners in a suitable concentration of benzylaminopurine (BAP) before grafting would enhance antioxidant activities and reduce oxidative stress, resulting in an increased successful grafting rate [10]. In walnut (Juglans regia) minigrafting, applying BA at an optimal concentration to the rootstocks could increase the rate of successful grafts [11].…”

Response regulator (RR) is the core component of cytokinin (CK) signaling, and it regulates the expression of numerous downstream CK-responsive genes. However, the knowledge regarding the pecan RR (CiRR) gene family is still limited. In this study, we first monitored trans-zeatin riboside (tZR) content in the graft union 0, 7, 14, and 32 days after grafting and then conducted genome-wide analysis and expression profiling of the CiRR gene family using an available genome sequence and RNA-seq dataset, aiming to better understand the roles of CK during pecan grafting. The dynamic contents of tZR showed an increased trend during the specific period for both the scion and rootstock. There were 20 CiRRs in the pecan genome, including 12 type A CiRRs, 5 type B members, and 3 type C genes. All members contained a receiver domain and type B CiRRs possessed an additional Myb-like DNA-binding domain. Promoter analysis showed that the CiRR gene family contained cis-elements associated with growth and development, hormones, and stress. A total of 10 genes, including CiRR18/9/4a/14a/12c/5/12b/14b/2b/2a, were abundantly expressed in the samples of different tissues, drought stress, and kernel development. There were 12 genes (CiRR5/18/4a/12b/2b/12c/14b/2a/14a/4b/9/11a) showing active expressions during grafting, and weighted gene co-expression network analysis (WGCNA) grouped them into six modules. Among them, CiRR14a and CiRR12b were the hub genes for the turquoise and brown modules, respectively. Functional annotation indicated that the turquoise module was associated with gene transcription and translation, while the brown module was related to cell proliferation. Our results suggest that the CiRR gene family central to CK signaling is probably involved in callus formation during pecan grafting.
