“…Silicon plays a significant role in promoting crop growth and improving crop resistance to biotic and abiotic stresses [ 13 , 23 ]. Previous studies have shown significant differences in gene expression in cucumber leaves after silicon addition [ 24 , 25 ]. In this work, silicon induced the differential expression of 602 genes.…”

Cucumbers grafted on rootstocks with different wax-removing abilities show varying levels of cold tolerance. The content of pericarp wax powder correlates with its silicon-metabolizing capacity, and rootstock grafting can alter not only the cold tolerance but also the silicon-metabolizing capacity of the scion. The molecular mechanisms responsible for resistance due to rootstocks and silicon and the pathway that affects cold tolerance, however, remain poorly understood. Therefore, we performed physiological and transcriptome analysis to clarify how rootstock types and silicon affect cold tolerance in cucumber seedlings. Then, we randomly selected eight differentially expressed genes (DEGs) for quantitative real time PCR (qRT-PCR) analysis to proof the reliability of the transcriptome data. The results showed that silicon can enhance the cold tolerance of cucumbers by boosting the phenylpropanoid metabolism, and rootstock grafting can boost the active oxygen scavenging ability and synthesis level of hormones in cucumbers and maintain the stability of the membrane structure to enhance cold tolerance. The difference in cold tolerance between the two rootstocks is because the cold-tolerant one has stronger metabolic and sharp signal transduction ability and can maintain the stability of photosynthesis, thereby contributing to the stability of the cellular system and enhancing tolerance to cold.

“…2′-grafted cucumber. A previous study reported that grafting increased the upregulation of the bloom transporter protein gene CsABC in cucumber [ 24 ]. This suggests that rootstocks alter fruit bloom content by affecting the bloom transporter protein activity in cucumber scions, which we have proved before.…”

“…In addition, graft-induced protein-coding RNAs and non-coding small RNAs have been detected in the scion or rootstock of vegetables ( Ren et al, 2018 ; Miao et al, 2019 ; Wang et al, 2019a , b ; Zhang et al, 2019a , b ; Aslam et al, 2020 ; Garcia-Lozano et al, 2020 ; Spanò et al, 2020 ) as well as woody species grafts ( Cookson et al, 2013 ; Corso et al, 2015 ; Kaja et al, 2015 ; Li et al, 2016 ; Chitarra et al, 2017 ; Pagliarani et al, 2017 ). Such graft-induced transcripts have a putative role in graft development, yield, fruit quality of scions and in response to abiotic or biotic factors ( Ren et al, 2018 ; Zhang et al, 2019a , b ; Garcia-Lozano et al, 2020 ; Spanò et al, 2020 ) (described in following sections).…”

Plant grafting is an ancient agricultural practice widely employed in crops such as woody fruit trees, grapes, and vegetables, in order to improve plant performance. Successful grafting requires the interaction of compatible scion and rootstock genotypes. This involves an intricate network of molecular mechanisms operating at the graft junction and associated with the development and the physiology of the scion, ultimately leading to improved agricultural characteristics such as fruit quality and increased tolerance/resistance to abiotic and biotic factors. Bidirectional transfer of molecular signals such as hormones, nutrients, proteins, and nucleic acids from the rootstock to the scion and vice versa have been well documented. In recent years, studies on rootstock-scion interactions have proposed the existence of an epigenetic component in grafting reactions. Epigenetic changes such as DNA methylation, histone modification, and the action of small RNA molecules are known to modulate chromatin architecture, leading to gene expression changes and impacting cellular function. Mobile small RNAs (siRNAs) migrating across the graft union from the rootstock to the scion and vice versa mediate modifications in the DNA methylation pattern of the recipient partner, leading to altered chromatin structure and transcriptional reprogramming. Moreover, graft-induced DNA methylation changes and gene expression shifts in the scion have been associated with variations in graft performance. If these changes are heritable they can lead to stably altered phenotypes and affect important agricultural traits, making grafting an alternative to breeding for the production of superior plants with improved traits. However, most reviews on the molecular mechanisms underlying this process comprise studies related to vegetable grafting. In this review we will provide a comprehensive presentation of the current knowledge on the epigenetic changes and transcriptional reprogramming associated with the rootstock–scion interaction focusing on woody plant species, including the recent findings arising from the employment of advanced—omics technologies as well as transgrafting methodologies and their potential exploitation for generating superior quality grafts in woody species. Furthermore, will discuss graft—induced heritable epigenetic changes leading to novel plant phenotypes and their implication to woody crop improvement for yield, quality, and stress resilience, within the context of climate change.

“…In 2019 alone, more than 20 studies were published that reported identification of new candidate genes for simply inherited mutants or QTLs in cucumber. These publications covered a variety of traits, such as resistance to cucumber vein yellowing virus (CVYV), powdery mildew and angular leaf spot (Pujol et al, 2019;Zhang et al, 2020a;2020b;2021), tolerance to abiotic stresses (heat and cold) (Dong et al, 2019;Wang et al, 2019b), plant architecture (Wen et al, 2019a;Njogu et al, 2020), flowering time, fruit size, shape, skin features, pedicel direction, and internal quality attributes (Rett-Cadman et al, 2019;Sun et al, 2019;Zhang et al, 2019Zhang et al, , 2020bGao et al, 2020;Sheng et al, 2020;Song et al, 2020;Pan et al, 2020b;Wang et al, 2020a;2020b;, and leaf color and shape mutations (Ding et al, 2019;Liu et al, 2019;Hu et al, 2020).…”

Vegetables are an integral part of the human diet worldwide. Traditional breeding approaches have been used extensively to develop new cultivars of vegetables with desirable characteristics, including resistance/tolerance to biotic and abiotic stresses, high yield, and an elevated content of compounds beneficial to human health. The technological progress since the early 1980s has revolutionized our ability to study and manipulate genetic variation in crop plants. The development of high-throughput sequencing platforms and accompanying analytical methods have led to sequencing and assembly of a large number of plant genomes, construction of dense and ultra-dense molecular linkage maps, identification of structural variants, and application of molecular markers in breeding programs. Linkage mapping and genome-wide association mapping studies have been used to identify chromosomal locations of genes and QTLs associated with plant phenotypic variations important for crop improvement. This review provides up-to-date information on the status of genomics and marker-assisted improvement of vegetable crops with the focus on tomato, pepper, eggplant, lettuce, spinach, cucumber, and chicory. For each vegetable crop, we present the most recent information on genetic resources, mapping populations, genetic maps, genome sequences, mapped genes and QTLs, the status of marker-assisted selection and genomic selection, and discuss future research prospects and application of novel techniques and approaches.
