“…The six enzymes mentioned above are all involved in the biosynthesis of phenylpropanoids ( Ferrer et al, 2008 ). Phenylpropanoids are secondary metabolites biosynthesized from phenylalanine in plants and they can enhance the ability of plants to resist various biotic and abiotic stresses ( Ye and Varner, 1995 ; Toquin et al, 2003 ; Korkina, 2007 ; Yu and Jez, 2008 ; Liu et al, 2016 ; Zhang et al, 2020 ). Chen et al reported that overexpression of LjPAL could enhance the resistance to Pseudomonas syringae pv.…”

Paenibacillus polymyxa is an important member of the plant growth-promoting rhizobacteria. P. polymyxa YC0136 inoculation had beneficial effect on growth promotion and biological control of tobacco (Nicotiana tabacum L.) under field conditions. This study aimed to reveal the growth-promoting mechanisms of strain YC0136. In growthpromotion assays, tobacco plant height was increased by 8.42% and 8.25% at 60 and 90 days, respectively, after inoculation with strain YC0136. Strain YC0136 also promoted the accumulation of tobacco biomass in varying degrees. Following inoculation with strain YC0136, 3,525 and 4,368 tobacco genes were up-regulated and down-regulated, respectively. Strain YC0136 induced the expression of plant hormone-related genes in tobacco, including auxin, cytokinin, and gibberellin, as well as transcription factors related to stress resistance such as WRKY and MYB. In addition, strain YC0136 induced the up-regulation of genes in the phenylpropanoid biosynthesis pathway by 1.51-4.59 times. Interaction with tobacco also induced gene expression changes in strain YC0136, with 286 and 223 genes up-regulated and down-regulated, respectively. Tobacco interaction induced up-regulation of the ilvB gene related to auxin biosynthesis in strain YC0136 by 1.72 times and induced expression of some nutrient transport genes. This study contributes to our understanding of the growth-promoting mechanisms of strain YC0136 on tobacco and provides a theoretical basis for the application of P. polymyxa YC0136 as a biological fertilizer.

“…In terms of the rootstock’s influence on ‘Isabelona’, various genes related to plant development displayed differential expression patterns ( Table 2 ). Combinations in which Garnem ® served as the rootstock exhibited an upregulation of genes associated with auxin regulation, likely in a repressive manner [ 41 , 42 , 43 , 44 ], indicating a potential reduction in apical dominance [ 45 , 46 ]. Auxin-related genes such as Aux/IAA can be found in phloem and might actually be synthetized in the rootstock: Lower expression of IAA4 in persimmon induced vigor [ 47 ], which is consistent with our observation.…”

“…In both ‘GN-8’ and Garnem ® rootstocks, an evident transcriptomic profile emerged, favoring cell division and differentiation, and consequently, tree vigor, in graft combinations with ‘Lauranne’ as the scion ( Table 3 and Table 4 ). This trend was manifested either through the upregulation of DEGs that promote cell division, root development, or cell wall formation [ 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 ], or the downregulation of genes that suppress plant development and lateral root formation [ 42 , 49 , 70 , 71 , 72 , 73 , 74 , 75 , 76 ]. Notably, genes associated with light perception and circadian clock regulation appeared to be influenced by the cultivar genotype ( Table 4 ).…”

The rootstock genotype plays a crucial role in determining various aspects of scion development, including the scion three-dimensional structure, or tree architecture. Consequently, rootstock choice is a pivotal factor in the establishment of new almond (Prunus amygdalus (L.) Batsch, syn P. dulcis (Mill.)) intensive planting systems, demanding cultivars that can adapt to distinct requirements of vigor and shape. Nevertheless, considering the capacity of the rootstock genotype to influence scion development, it is likely that the scion genotype reciprocally affects rootstock performance. In the context of this study, we conducted a transcriptomic analysis of the scion/rootstock interaction in young almond trees, with a specific focus on elucidating the scion impact on the rootstock molecular response. Two commercial almond cultivars were grafted onto two hybrid rootstocks, thereby generating four distinct combinations. Through RNA-Seq analysis, we discerned that indeed, the scion genotype exerts an influence on the rootstock expression profile. This influence manifests through the modulation of genes associated with hormonal regulation, cell division, root development, and light signaling. This intricate interplay between scion and rootstock communication plays a pivotal role in the development of both scion and rootstock, underscoring the critical importance of a correct choice when establishing new almond orchards.

“…IAA4 (Prudul26A024452) is also overexpressed in the 'Isabelona'/Garnem ® combination (Table 3). IAA4 acts in opposition to auxin response, inhibiting the formation of adventitious roots [71]. Therefore, there is an upregulation of processes that lead to reduce lateral root formation when 'Isabelona' is the scion.…”

Background: Rootstock genotype determines multiple aspects of the scion development, including the scion three-dimensional structure, or tree architecture. Thus, rootstock choice is an important factor in the establishment of new almond (Prunus amygdalus (L.) Batsch, syn P. dulcis (Mill.)) planting systems, which demand cultivars whose vigor and shape adapt to these new requirements. However, if the rootstock genotype is able to alter scion development, it is likely that the scion genotype affects the rootstock performance. Results: We carried out a transcriptomic analysis of the scion/rootstock interaction in young trees, focusing on the scion effect in the rootstock molecular response. Two commercial almond cultivars were grafted onto two hybrid rootstocks, resulting in four combinations, whose gene expression in both scion and rootstock tissue was analyzed via RNA-Seq. We observed that, in fact, the scion genotype has an impact on the rootstock expression profile, affecting the expression of genes associated with hormonal regulation, root development and light signaling. Conclusions: Scion/rootstock communication has a pivotal role in the development of both scion and rootstock, accentuating the importance of a correct choice when establishing new almond orchards.
