Medicago Sativa L. Saponin‐Driven Lactobacillus Intestinalis Restores Intestinal Stemness in Naturally Aged Mice via the Bile Acid‐FXR‐Wnt Signaling Axis

open access: yesAdvanced Science, EarlyView.
This study examines the mechanism by which alfalfa saponin (AS) regulates intestinal stemness via modulation of the gut microbiota. The results indicate that AS significantly increases the abundance of Lactobacillus intestinalis, which subsequently activates Wnt signaling via bile acid metabolism and enhances intestinal stemness. These findings provide

The Importance of Being Imperfect: Structure and Function of Bacterial Amyloid

open access: yesAdvanced Science, EarlyView.
Functional bacterial amyloids such as CsgA and FapC have been widely studied to understand the relationship between aggregation and function. The recently solved structure of FapC reveals a Greek‐key motif in which extensive hydrogen bonding and packing interactions formed by residues in conserved imperfect repeats stabilize a β‐solenoid core.

Compartmentalized Homeostasis Drives High Bamboo Forest Productivity under Nutrient Imbalance

open access: yesAdvanced Science, EarlyView.
This study reveals how Moso bamboo achieves high productivity despite nutrient‐poor soils. It employs a unique strategy, maintaining strict nutrient balance in its leaves while using woody tissues as flexible storage reservoirs. This compartmentalized mechanism buffers the plant from soil phosphorus limitation and microbial competition, resolving the ...
