Forsythia

Forsythia is a genus of deciduous shrubs in the olive family, Oleaceae.
These plants are known for their bright yellow flowers that bloom in early spring, often before the leaves appear.
Forsythia species are native to eastern Asia and have been widely cultivated as ornamental plants in gardens and landscapes around the world.
The genus includes around 10 species, which vary in size, shape, and flowering characteristics.
Forsythia are hardy, easy-to-grow shrubs that thrive in full sun to partial shade and a variety of soil types.
They are commonly used in hedges, borders, and mass plantings, and their vibrant flowers make them a popular choice for spring landscaping.
Reserach on the medicinal and phytochemical properties of Forsythia is an active area of study.

P. gingivalis FDC 381, T. denticola ATCC 35404, and T. forsythia ATCC 43037 were used in this study and were routinely cultured anaerobically at 37°C as described previously [33] (link), [35] (link). Bacterial concentration was determined and cells were resuspended in reduced transport fluid (RTF) at 1010 cells per mL [35] (link). For topical oral polymicrobial infection, P. gingivalis was mixed with an equal quantity of T. denticola for 5 min; subsequently, T. forsythia was added to the culture tubes containing P. gingivalis and T. denticola, and cells were mixed thoroughly and allowed to interact for an additional 5 min. P. gingivalis, T. denticola, and T. forsythia were then mixed with an equal volume of 4% (w/v) sterile carboxymethylcellulose (CMC; Sigma-Aldrich, St. Louis, MO) in phosphate buffered saline (PBS), and this mixture was used for oral infection (5×109 bacteria per mL) in ApoEnull mice as described previously [35] (link).

Gene knock-outs were based on the homologous recombination of a gene knock-out cassette deleting or disrupting the selected gene of the T. forsythia T9SS. Positive clones were selected based on transferred erythromycin resistance.
The gene knock-out cassette for constructing the TFΔ0955 mutant consisted of a 2,188-bp erythromycin resistance gene ermF-ermAM (primer pair 415/416) flanked by homologous up- and down-stream regions (Fig. 1A). Genomic DNA from T. forsythia ΔwecC (obtained from A. Sharma, State University of New York at Buffalo, USA) was used as a template. The 1,035-bp up-stream and 1,027-bp down-stream homology regions were amplified from genomic DNA of T. forsythia wild-type cells using the primer pairs 413/414 and 417/418, respectively. The three fragments were joined by overlap extension (OE-) PCR and sub-cloned into the blunt-end cloning vector pJET1.2 (Thermo Scientific) resulting in pJET1.2/TF0955ko. Approximately 5 μg of the circular gene knock-out construct were transferred by electroporation into 100 μL of T. forsythia culture grown to the early stationary phase. Cells were regenerated in BHI medium for 24 h before plating on BHI agar plates containing erythromycin as selection marker. Single colonies were picked and used for inoculation of liquid BHI medium. Once bacterial growth was visible, genomic DNA was isolated to confirm the integration of the knock-out cassette via PCR amplification using the primer pair 426/429.
The construction of the TFΔ2327 mutant was done essentially the same way as described for TFΔ0955 (Fig. 1B). Genomic integration of the gene knock-out cassette was verified using the primer pair 448/449.
Growth of the T9SS mutants was measured over a period of 5 days and the obtained growth curves were compared to that of T. forsythia wild-type.

The RNA-seq data of 79 weeping forsythia WRKY genes were downloaded from NCBI, including data from fruit, stem, leaf (accession no. SRR17386487-SRR17386495), and flower tissues (accession no., SRX11342985, SRX11342993 and SRX11342994). RNA-seq data from fruit, stem, leaf was obtained at harvest time (July) of the weeping forsythia fruit (Li et al., 2022). RNA-seq data of flower were obtained at the flower bud period (March). The gene expression data of weeping forsythia under drought stress were from Wuzhishan populations under 80% and 20% soil water content (accession no. SRX7503009, SRX7503010, SRX7503012-SRX7503015; Li et al. 2021b (link)). The gene expression data of weeping forsythia under cold stress were from Wuzhishan populations at 25 ℃ and 4 ℃ (accession no. SRX7440183-SRX7440188; Li et al. 2021c (link)).
Low-quality reads with more than 10% anonymous nucleotides (N) and more than 50% of bases possessing a value Q ≤ 10 were removed from raw sequencing data. The gene expression level of all genes in these samples was estimated by fragments per kilobase of transcript per million fragments mapped (FPKM) using StringTie (Pertea et al. 2015 (link)). The expression patterns in different tissues and in response to drought and cold stresses were analyzed using the R package Heatmap. Log2FPKM ≥ 1 was used as the threshold to screen the WRKY genes that were effectively expressed in different tissues of weeping forsythia. Under drought and cold stresses, FC ≥ 2 and FDR ≤ 0.05 were used as the thresholds to screen WRKY genes involved in stress response.

The main outcome variable was the reduction in PPD at 3 and 6 months after intervention, while BOP, CAL, REC, FMPS, FMBS, pocket closure, and detection scores of the five selected bacterial species’ changes (A. actinomycetemcomitans, P. gingivalis, T. forsythia, P. intermedia and T. denticola) were regarded as secondary outcomes. For each of the quantitative variables PPD, REC, CAL, a patient mean value was computed per time point, which was further used in the statistical analyses. Differences between groups for variables measured on a continuous or ordinal scale were analyzed using Kruskal–Wallis tests, with post hoc Mann–Whitney pairwise tests as necessary. Proportions were compared by chi-square tests. Assessment of intragroup differences between successive time points for quantitative variables was performed using Friedman tests, with subsequent Wilcoxon signed-rank tests for pairwise comparisons. The Bonferroni correction was used to account for multiple comparisons. p values < 0.05 were accepted for statistical significance. The statistical analyses were performed using the software R version 4.1.2 [43 ]. Changes in the detection frequency scores of the main keystone bacteria were evaluated in terms of the microbiological status. Results were noted and categorized into one of four groups: 0 = nondetectable, 1 = detectable < 104 (103 for A.a.), 2 = 104–105 (103–104 for A.a.), 3 = 105–106 (104–105 for A.a.), and 4 ≥ 107 (106 for A.a.) [42 (link)]. Using the Wilcoxon signed-rank test, intragroup comparisons of detection scores of pathogen species between the baseline and 6-month reevaluation time points were made. For intergroup comparisons of the detection scores at each time point, the Kruskal–Wallis test was applied.
