Abstract Arbuscular mycorrhizal (AM) fungi are important plant symbionts that provide plants with nutrients and water as well support defences against pests disease.

In response to herbivory, plants employ several inducible defenses mitigate herbivore damage. These plant-induced responses can trigger subtle changes in plant metabolite composition, altering the profiles of plant-produced exudates such as (extra-) floral nectar and guttation. Natural enemies consume these exudates, which serve consistent nutrient-dense food sources. There is mounting evidence that natural enemies' access impacts their fitness, performance, life history traits. Nonetheless, role induced defense on subsequent effect remains under-researched. This review, thus, highlights potential with a particular emphasis altered metabolic affecting resource nutritional value consequently fitness performance enemies. Future directions implications biological control practices are also highlighted.

Summary Polyploidy plays a major role in diversification and speciation of almost all plants. Separately, the microbiome is recognized for its ubiquitous plant functioning. Despite importance both processes, we lack synthetic picture their reciprocal relationship. I forge this missing linkage by presenting ways which polyploidy can shape how turn affect polyploid phenotype fitness. illustrate these interactions drawing on small, but compelling, set comparisons plant–microbial community interaction with taxa representing different stages continuum thereby shed light advantages may be influenced microbes. use findings from range studies to build case plant–microbiome key pathways persistence: overcoming minority cytotype disadvantage increasing competitive ability and/or niche shifts relative diploids. put forward likely stress tolerance, abiotic breadth, limits coexistence. conclude identifying research needed test hypotheses doing so could transform our understanding as driver ecology evolution.

Summary Floral traits, including floral display and nutritional rewards from pollen nectar, drive pollinator visitation. Even within a single plant species, environmental factors can influence the quality quantity of resources. Yet, ecological interactions driving this variation in resources, especially those belowground, remain unknown. Here, we investigate how soil microbial community composition nutrient availability, specifically distinct arbuscular mycorrhizal fungi (AMF) species phosphorus (P) supply, affect growth, AMF that, turn, affects bee We found that increased richness functional diversity enhanced (flower size number) (nectar volume protein) Using structural equation modeling, associations could boost visitation by enhancing flower size. However, trade‐offs occur; correlates negatively with root colonization but positively hyphal length, suggesting traits effects on growth. Overall, effect was not homogenous; instead, trait differences interact P resulting varying subsequently foraging dynamics. These results highlight focusing beneficial belowground provide an opportunity to bolster
