Introduction: Stress-induced volatile organic compounds (VOCs) that induce plant immunity bear potential for biocontrol. Here, we explore the potential of nonanal to enhance the seed yield of common bean () under open field conditions that are realistic for smallholder farmers.
Methods And Results: Using plastic cups with a nonanal-containing lanolin paste as low-cost dispensers, we observed that exposure of Flor de Junio Marcela (FJM) plants over 48h to airborne nonanal was followed by a 3-fold higher expression of pathogenesis-related (PR) genes PR1 and PR4.
Extracellular DNA as a Strategy to Manage Vascular Wilt Caused by in Tomato ( L.) Based on Its Action as a Damage-Associated Molecular Pattern (DAMP) or Pathogen-Associated Molecular Pattern (PAMP).

Article Synopsis
- - Vascular wilt is a major disease impacting tomato yields globally, caused by a specific pathogen that has developed resilience against traditional management strategies due to its ability to persist in soil and invade vascular tissues.
- - Current research is exploring plant defense mechanisms and the use of extracellular DNA (eDNA) to help tomatoes recognize and respond to disease, distinguishing between their own eDNA and that of pathogens.
- - Findings indicate that applying the eDNA of the pathogen in soil can reduce disease severity in tomatoes, enhance certain beneficial compounds, and stimulate defense gene expression, suggesting it could be a viable strategy for managing vascular wilt.
Cheese whey (CW), by-product of cheese production, has potential as a valuable resource due to its nutritional composition. Although options for CW degradation have been explored, a biological treatment with black soldier fly larvae (BSFL) has not been reported. This study evaluated the growth and composition of BSFL in four experimental diets with CW under different conditions.

Secondary metabolites, bioactive compounds produced by living organisms, can unveil symbiotic relationships in nature. In this study, soilborne entomopathogenic nematodes associated with symbiotic bacteria ( and ) were extracted from solvent supernatant containing secondary metabolites, demonstrating significant inhibitory effects against , , , , , and . The characterization of these secondary metabolites by Fourier transforms infrared spectroscopy revealed amine groups of proteins, hydroxyl and carboxyl groups of polyphenols, hydroxyl groups of polysaccharides, and carboxyl groups of organic acids.

Compost, biofuels, animal feed, dyes, and bioactive compounds can be obtained from the revaluation of organic waste. Research on this subject is scarce and limited to specific sectors, such as agriculture and agroindustry, leaving aside others that generate large quantities of organic waste, such as floriculture.
