TL;DR

The results demonstrated that switchgrass PvKN1 is a putative ortholog of maize KN1 that is linked to plant ligniﬁcation and cell wall and development traits as a major regulatory gene and targeted overexpression of PvKN1 in bioenergy feedstocks may provide one feasible strategy for reducing biomass recalcitrance and simultaneously improving plant growth characteristics.

Reduced root lignification resulting from enhanced brassinosteroid signaling compromises waterlogging tolerance in Nardostachys jatamansi seedlings.

The alpine plant Nardostachys jatamansi is highly sensitive to waterlogging stress, and phytohormone signaling plays a critical role in its adaptation to this abiotic stress. Nevertheless, the involvement of brassinosteroid signaling in the response of N. jatamansi to waterlogging stress remains poorly characterized. I...

Advances in Genes Associated with Straw Degradation in Rice

Rice (Oryza sativa L.) generates approximately 300 million tons of straw annually worldwide, and efficient degradation and valorization remain critical bottlenecks for sustainable agriculture. Straw degradability is fundamentally constrained by cell wall recalcitrance, which is determined by the composition and archite...

Mechanisms of gradient enzymatic conversion of lignin by a dual-fungal system consisting of Phanerochaete chrysosporium and Pleurotus eryngii.

This study systematically elucidates the synergistic lignin conversion mechanism of CDGs by a fungal consortium from structural, enzymatic, and metabolic perspectives, uncovering a temporal division of labor together with new lignin catabolic pathways that provide a mechanistic framework for the biological valorization...

A Novel Gene IrXyn01 Coding β-Xylanase Is Essential for Ilyonectria robusta Pathogenicity in Early Ginseng Infection

Ginseng (Panax ginseng), a traditional and valuable medicinal plant, is severely affected by rusty root rot caused by Ilyonectria robusta. Xylanase is hypothesized to play a key role in the pathogenicity of I. robusta. Through transcriptomic analysis during ginseng infection, the highly expressed xylanase gene IrXyn01...

Heterologous Expression of a Neurospora crassa Catalase Reprograms the Cellulase System and Enhances β-Glucosidase Production in Trichoderma reesei

Efficient saccharification of lignocellulose, the most abundant renewable carbon reservoir resource, is of great industrial importance. Trichoderma reesei is a premier cellulase producer, but its fermentation efficiency is often constrained by dual challenges: dissolved oxygen limitation and intrinsic oxidative stress....
