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.

Overall, brassinosteroid signaling allocates limited carbon to root elongation instead of lignin synthesis for physical barrier formation, resulting in severe radial oxygen loss and energy crisis.

Advances in Genes Associated with Straw Degradation in Rice

A three-parameter analytical framework is proposed, including cellulose crystallinity, hemicellulose side-chain modification, and lignin monomer composition and cross-linking density, to systematically assess the regulatory role of endogenous rice genes in straw degradability.

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....
