Metabolic convergence on TOR signaling in the chestnut blight fungus and its regulation by host plant signals

open access: yesNew Phytologist, EarlyView.
Proposed model of metabolic convergence on the target of rapamycin (TOR) pathway in Cryphonectria parasitica. Twelve core genes involved in diverse metabolic pathways act as upstream regulators or downstream effectors of TOR kinase. Dysregulation of these genes mimics an inhibited TOR state, leading to restricted hyphal growth and enhanced trehalose ...

The OsWRKY15‐OsSUT3 Regulatory Module Enhances Rice Pollen Fertility by Mediating Sucrose Allocation to Anthers

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Sucrose transport and starch accumulation are crucial carbohydrate metabolic processes in rice, playing essential roles during late pollen development to ensure pollen maturation, fertility and high grain production. However, the molecular mechanisms regulating sucrose transport and starch accumulation during rice pollen development remain ...

A Gain‐of‐Function Mutation in DELLA Selectively Alters Protein Interactions to Regulate Wheat Tiller Angle and Plant Height

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant architecture, especially plant height and tiller angle, plays a pivotal role in determining wheat yield. In this study, we characterize a wheat mutant termed prostrate and semidwarf 1 (prose1), exhibiting both a prostrate growth habit and semidwarfism.

The Cytosolic Iron–Sulfur Cluster Assembly Targeting Complex Is Hijacked by Magnaporthe Effector AvrPi9 to Suppress Rice Resistance

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT The cytosolic iron–sulfur (Fe‐S) cluster assembly (CIA) targeting complex mediates the maturation of cytosolic and nuclear Fe‐S proteins and governs core eukaryotic cellular processes. However, whether this complex contributes to plant disease resistance remains unclear.

A Heat‐Inducible Rubisco Activase Safeguards Photosynthesis via Multilevel Regulation and Dual Function

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Rubisco activase (RCA) is critical for maintaining photosynthetic efficiency under heat stress, yet its regulatory mechanisms and functional diversification remain poorly understood. Here, we characterize a novel heat‐inducible RCA family member (RCA1), which plays a pivotal role in mediating multidimensional thermotolerance in a tropical ...
