ABSTRACT Asparagus ( officinalis ) is an important perennial vegetable crop cultivated worldwide. Its productivity and field longevity are often threatened by soilborne pathogens such as Fusarium spp., which cause wilt rot diseases. These severely reduce yield negatively impact the economic viability of asparagus cultivation. However, interaction between involves a complex interplay processes, including pathogen recognition, activation defence signalling pathways disease susceptibility. processes regulated specific metabolites that may serve signals or even facilitate infection. Despite progress in understanding mechanisms plants like Arabidopsis thaliana cereal crops, knowledge about –Fusarium pathosystem remains limited. Specifically, mechanism host regulate asparagus– still needs to be fully exploited. This article explores defensive responses towards infection spp. delves into regulatory interaction. Understanding dynamics these interactions essential for devising strategies manage ‐related diseases effectively develop disease‐resistant varieties.

Changes in climatic factors and rhizosphere microbiota led plants to adjust their metabolic strategies for survival under adverse environmental conditions. plant metabolites can mediate crop growth development interact with of the rhizosphere. To understand interactions among factors, microbiota, tobacco, a study was conducted by using integrated metagenomic metabolomic at four typical representative tobacco planting sites Yunnan, China. The results showed that agronomical biochemical traits were significantly affected temperature, precipitation (PREP), soil pH, altitude. Correlation analyses revealed significant positive correlation temperature length, width, area leaf, while PREP correlated height effective leaf numbers. Furthermore, total sugar reducing contents baked leaves higher, nitrogen alkaloid levels lower site low PREP.
