“…Sucrose is a common photosynthate that plants produce for their own metabolism or which is secreted as root exudates for host colonization by microbes. The addition of a high level of sucrose (15 g/L) to A. thaliana [55] and potato [56] generated a plant phenotype distinguished by later onset of flowering and more leaves, which was due to the regulation of sets of sucrose-metabolizing enzymes such as invertase (INV) [57], sucrose synthase (Sus) [58], and the sucrose non-fermenting-regulating-related kinase (SnRK1) [59]. Furthermore, sucrose can also function as an osmotic signal to activate transcription factors, such as MYB75, phytochrome-interacting factor (PIF), and basic helix-loop-helix (bHLH), in plant cells, thereby affecting the growth, flowering [60], and productivity of plants and their circadian clock [61].…”

Rheum palmatum L. is an important traditional Chinese medicinal herb now in demand worldwide. Recently, the theoretical framework suggested that sucrose triggers colonization of PGPM (plant growth-promoting microbes) in the rhizosphere, but their interactions on the plant remain largely unknown. Here, we applied three concentrations of both Bacillus amyloliquefaciens EZ99 inoculant (1.0 × 105, 1.0 × 106, and 1.0 × 107 colony-forming units (CFU)/mL, denoted as LB, MB, and HB, respectively) and sucrose (0.15, 1.5, and 15 g/L, denoted as LS, MS, and HS, respectively) to investigate their co-effects on R. palmatum in a field experiment. The results showed that LB + MS (1.0 × 105 CFU/mL Bacillus + 1.5 g/L sucrose) and LB + LS (1.0 × 105 CFU/mL Bacillus + 0.15 g/L sucrose) treatments significantly increased root fresh weight (p ≤ 0.05). Metabolite analysis revealed that the treatment LB + LS significantly increased the relative content of major active components in rhubarb, namely anthraquinones and phenolic compounds, by 1.5% and 2.3%. Although high sucrose addition increased the activities of certain soil enzymes, the LB + LS treatment significantly increased total potassium (TK), whereas it decreased available potassium (AK), which facilitated the potassium utilization in rhizosphere soil. Furthermore, rhizosphere microbiomes revealed that fungal diversity was augmented in LB + LS treatment, in which the common causative fungal pathogen Fusarium spp. showed an effective suppression. Additionally, the redundancy analysis and Spearman correlations revealed a positive relationship of Sphingomonas associated with change in potassium bioavailability. Altogether, our findings suggest that the combined application of a bacterial inoculant and sucrose can improve the growth and quality of R. palmatum, and stimulate uptake of plant nutrients that contribute to alter the microbial community for biocontrol potential. Hence, this work not only has broad application prospects across economical plants, but also emphasizes agroecological practices for sustainable agriculture.

“…It is interesting that the analysis of the intraspecific polymorphism of the domain in potato (Solanum tuberosum) showed a remarkably higher level of variability of 2.4% [17], and the interspecific polymorphism of the same domain in ten apple species (Malus) was 8% [18].…”

The genus Brassica contains a rich diversity of species and morphological types, including leaf, root, and oil crops, all of which show substantial phenotypic variation. Both Chinese cabbage and cabbage are typical leaf-type crops with normal roots. We created translocation lines based on interspecific crosses between Chinese cabbage and cabbage and identified qdh225, which exhibited a swollen-root phenotype. The swollen root of qdh225 contained a large number of granular substances, and the formation of its irregular morphological tissue was caused by a thickening of the phloem. Transcriptomic and metabolomic data suggested that differential expression of genes encoding nine types of enzymes involved in starch and sucrose metabolism caused changes in starch synthesis and degradation in the swollen root. These genes jointly regulated sucrose and starch levels, leading to significant enrichment of starch and soluble proteins in the swollen root and a reduction in the content of soluble sugars such as D-glucose and trehalose 6-phosphate. A significant increase in IAA and ABA contents and a decrease in GA content in the swollen root likely promoted the differential expression of genes associated with hormone signal transduction, thereby regulating the development of the swollen root. Taken together, our data suggest that accumulation of IAA and ABA and reduction in GA promote swollen root formation by regulating hormone-mediated signaling, leading to a thickening of phloem, root enlargement, and substantial accumulation of starch and soluble proteins. The latter provide materials, energy, and nutrient sources for the development of swollen roots.
