Article Abstract

A two-year field study evaluated biodegradable plastic film (BPF; thicknesses: 0.006, 0.008, and 0.010 mm) versus polyethylene film (PE; 0.010 mm) and no-mulch control on sugarcane yield and weed suppression. Key results demonstrated that 0.010 mm BPF significantly enhanced sugarcane emergence ( = 5.07% in ratoon), reduced weed biomass by 70%, and increased perennial yield by 3.83% (+5.6 t ha), while PE film decreased yield by 3.80%. Regression analysis identified the effective stem number, plant height, and stem diameter as primary yield predictors ( = 0.996). Logistic models revealed that film mulching duration >119 days was critical for achieving high yields (>122.2 t ha) and sustained weed control ( = 0.81). These findings establish 0.010 mm BPF as an optimal sustainable alternative to PE film for enhancing sugarcane productivity.

The fall armyworm (Spodoptera frugiperda, FAW) has developed varying degrees of resistance to chlorantraniliprole (CAP). Apoptosis serves as a critical defense mechanism against pesticide stress in insects. Here, we identified a juvenile hormone (JH)-mediated apoptotic pathway through RNA-seq, revealing nine JH-induced apoptosis-related genes (four positively correlated and five negatively correlated).

The co-infection of maize chlorotic mottle virus (MCMV) and sugarcane mosaic virus (SCMV) causes maize lethal necrosis (MLN), which seriously affects the yield and quality of maize. Ubiquitination is one of the most important protein post-translational modifications. However, the role of ubiquitination modification in regulating maize resistance to viral infection remains largely unknown.

This Perspective explores how new technologies can expand lignocellulose biorefineries to include coproducts for animal feed and microbial protein with potential applications in human food. Using the Brazilian sugarcane industry as a case study, the analysis highlights synergies from the spatial coexistence of sugarcane and livestock, as well as economies of scale and product multiplicity in biorefineries. The technology outlook examines selected biomass pretreatments that can generate pretreated biomass with dual use: reactive intermediate for cellulosic ethanol production and ruminant nutrition.

Natural polysaccharides are abundant, cost-effective, renewable, accessible to modification, and possess biodegradable and biocompatible properties. Sugarcane bagasse, a widely available agro-industrial byproduct, was utilized as a source for preparing nanocellulose fibers (NCFs) and carboxymethyl cellulose nanofibers (CM-CNFs). A combination of chemical and mechanical processes was used to isolate the fibers, followed by carboxymethylation to introduce functional groups and enhance dispersion in polymer matrices.
