“…For the brown module, the enriched terms such as 'mitotic cell cycle', 'cell division', and 'microtubule cytoskeleton organization' were proven to be associated with cell proliferation [36,63,64]. During the formation of a graft union, callus guarantees the nutrients and signal transduction between the graft partners, which is an essential prerequisite for successful grafting [65]. As CiRR12b exhibited a similar expression pattern compared to most of the module genes, it was likely to play a positive role in callus formation.…”

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.

“…The photosynthetic parameters varied among the 21 scion-rootstock combinations. The highest rate of net CO 2 assimilation (A CO2 ) were observed in Swingle combined with both Ban eld and Chislett (BF/SW, CH/SW) at 11 22. and 10.77µmol m − 2 s − 1 , respectively, and MXT with Trifoliate orange (PW/TO) at 153.97 mmol m − 2 s − 1 .…”

Photosynthesis is an essential biological process of the plant. The performance of photosynthesis could remarkably affect the final yield and quality of the fruit. However, the effect of the scion, rootstock and their interaction in the scion-rootstock combinations on photosynthesis of the tree was not clear. In this research, the performance of photosynthesis was analyzed with 21 citrus scion-rootstock combinations derived from three navel oranges (Citrus sinensis cv. ‘Banfield’, ‘Chislett’ and ‘Powell’) grafted on seven rootstocks (Swingle citrumelo (C. paradisi × Poncirus trifoliata), Carrizo citrange (C. sinensis × P. trifoliata), X639 (C. reticulata × P. trifoliata), MXT (C. sinensis × P. trifoliata), Hongju (C. reticulata), Ziyang xiangcheng (C. junos) and Trifoliate orange (P. trifoliata), respectively. Results indicated that photosynthesis was significantly affected by either scion, rootstock or the interaction of scion-rootstock, and rootstock had more effect in the scion-rootstock combinations, but the effects among the rootstocks were variable. The combinations of Swingle demonstrated higher values of photosynthesis indexes. Two of three scions grafted on Swingle had significantly higher net CO2 assimilation rate (ACO2). All three scions grafted on Swingle showed the highest electron transport rate (ETR) and quantum yield of PSII (Yield II). Photosynthetic pigments (Chla, Chlb, Car and Chlt) of the three scions were highest on Ziyang xiangcheng. Banfield/Trifoliate, Powell/Trifoliate and Chislett/Ziyang had the highest Rubisco activities. The scion-rootstock interaction made the light quanta enter into other reactions during the processes of photosynthesis. Electron transport rate (ETR) is probably the predominant factor determining the photosynthesis of plant.

“…Cold-hardy rootstocks could be an option for winter cold-challenged sites (Davenport et al 2008 ). Targeted selection of rootstocks for grafting cultivation can not only maintain the good characteristics of the varieties, but also improve the adaptability and resistance to stress of good varieties, expand the range of cultivation range, and increase the yield (Liu et al 2023 ). Additionally, it can reduce the thickness and width of the cover soil and reduce the cost of cold protection.…”

In northwest China, where winter is extremely cold and the grapevine is vulnerable to freezing damage, the application of soil covering has promoted the vigorous development of the local grape and wine industries. However, in recent years, the negative effects of burying soil for cold protection on the environment have gradually emerged. In some viticultural regions, the phenomenon of "summer forest, winter desert" has appeared. Therefore, it is urgent for the Chinese grape industry to find a better solution to overwinter safely and environmentally friendly. This review summarizes the advantages and disadvantages of widely used solutions to overwinter such as covering vines with soil, breeding of cold-resistant grapes, cold-resistant cultivation model, physical and chemical covering materials, and protected grape facilities were reviewed. Future overwintering measures were proposed which avoid burial and grape overwintering research directions. It also provides a theoretical foundation and technical support to improve grape yield and quality in northwest China.
