Results of real-time qPCR analysis of the virulence of germplasm isolates in competition with Pseudomonas syringae pv. actinidiae (Psa) on Actinidia arguta at 7 days postinoculation (dpi). Plantlets were flooded with 106 CFU/ml of each bacterial isolate. Bacterial growth was quantified by real-time qPCR using isolate-specific primers and normalizing the cycle threshold (Ct) to a plant housekeeping gene, EF1α, to get a ΔCt value.

A sampling overview diagram. Trees are organized into infestation categories based on the following criteria. A: Emerald ash borer (EAB)-infested phloem in the bottom 2 m of the tree during the entire study period. B: EAB-infested phloem is absent in the bottom 2 m of the tree at the start of the study but present at the end of the study. C: Trees show symptoms of EAB infestation in canopy but no EAB-infested phloem in the bottom 2 m of the tree. D: No symptoms of EAB infestation. The orange in the figure provides a simplified representation of the locations of EAB galleries within the tree in each infestation category. The control phloem samples are labeled as CP, uninfested phloem before EAB reached the base of the tree is labeled as UP Before, uninfested phloem after EAB reached the base of the tree is labeled as UP After, infested phloem is labeled as IP, frass is labeled as F, and the larval samples are labeled as La.

Using data from rhizosphere soil from 95 field-grown sunflower inbred lines, Clifton P. Bueno de Mesquita et al. found that heritable genetic differences affect sunflower rhizosphere archaeal, bacterial, and fungal communities across all taxonomic levels: doi.org/10.1094/PBIOMES-05-25-0034-R

Sloan's neutral model for A, archaea/bacteria and B, fungi. In both datasets, only zero-radius operational taxonomic units (ZOTUs) with at least 15 reads across the whole dataset were included (n = 10,522 and 1,425, respectively). Inset pies show the proportion of ZOTUs that were above (positive selection), below (negative selection), or in (no selection) the neutral model. The solid blue line represents the best fit to the neutral model, and the dashed blue lines are the 95% confidence intervals. The R2 is the fit to the neutral model, and the Nm is the metacommunity size times immigration.

Results from Hayden W. Bock et al. indicated that groundcovers modulate bacterial and fungal composition in vineyard soil microbiomes within and beyond their rooting zones. Learn more: doi.org/10.1094/PBIOMES-11-25-0087-… #microbiome

Fig. 1.
Grass groundcovers have denser, shallower root systems than grapevines. When planted in vineyards, grapevines redistribute roots deeper to avoid competition. This results in more roots overall, with substantial groundcover roots at shallow depths and grapevine roots beyond the groundcover root zone. This figure demonstrates our hypothesis that groundcovers promote a more diverse and compositionally distinct bulk-soil microbiome, favoring decomposer taxa associated with increased soil carbon inputs. We expected these effects to be greatest near the surface, where grass roots dominate, and diminish with depth.

To further understand how microbes influence heterosis, Kayla M. Clouse et al. characterized variation in maize heterosis when grown in soil inocula derived from historical maize farms or prairies: doi.org/10.1094/PBIOMES-04-25-0026-R

Fig. 1.
In experiment 1, we grew maize with agricultural, prairie, or sterile control inocula under controlled growth chamber settings. After 4 weeks of growth, better-parent heterosis (BPH) was greatest in the second agricultural soil for A, stem diameter and greatest in the second prairie soil for B, week-4 chlorophyll concentration. Points show the estimated marginal mean (EMM) values for each genotype in each soil, and error bars show the standard error for the EMMs (Dunnett's test: ns = not significant, P > 0.05; * = P < 0.05; ** = P < 0.01; *** = P < 0.001). C, BPH was calculated for soil inoculum using EMM values for stem diameter and week-4 chlorophyll concentration. The observed ΔBPH is shown as a vertical red line, and the histogram shows the distributions of ΔBPH for 999 permutations of the data with respect to soil inocula.
