Pectin Metabolism Influences Phloem Architecture and Flowering Time in Arabidopsis Thaliana

open access: yesAdvanced Science, EarlyView.
Cell wall remodeling mediated by changes in pectic homogalacturonan, including its methyl‐esterification status and degradation, shapes wall architecture. This study finds that pectin metabolism dynamically modulates wall properties and triggers auxin responses, which influence phloem morphogenesis and function, mediating the long‐distance transport of

Contrasting nutritional acclimation of sugar maple (Acer saccharum Marsh.) and red maple (Acer rubrum L.) to increasing conifers and soil acidity as demonstrated by foliar nutrient balances

open access: yesFrontiers in Ecology and Evolution, 2016
Sugar maple (Acer saccharum Marshall, SM) is believed to be more sensitive to acidic and nutrient-poor soils associated with conifer-dominated stands than red maple (Acer rubrum L., RM).

TaPPR13, a Pentatricopeptide Repeat Protein Gene Activated by TaBZR2, Confers Drought Stress Tolerance by Enhancing the Antioxidant Defense System and Promoting Retrograde Signaling in Wheat (Triticum aestivum)

open access: yesAdvanced Science, EarlyView.
TaPPR13, a PPR protein family gene in wheat is activated by TaBZR2 to enhance drought stress tolerance and photosynthetic capacity. It achieves this by interacting with TaAOR1 and TaSIG5 to improve antioxidant defense and regulate chloroplast gene expression. Abstract The wheat (Triticum aestivum) brassinazole‐resistant 2 (TaBZR2) gene is identified as

Inhibition of RNase to Attenuate Fungal‐Manipulated Rhizosphere Microbiome and Diseases

open access: yesAdvanced Science, EarlyView.
Fusarium graminearum uses its virulence effector Fg12, a fungal RNase, to manipulate the host rhizosphere microbiome and promote infection. Guanosine monophosphate (GMP) blocks Fg12's RNase activity. This reveals a key pathogen‐microbiota interaction mechanism and proposes GMP as a targeted strategy to disarm this core fungal effector, offering a ...
