The soil microbiome can increase crop resilience to both abiotic and biotic stress, there is growing interest in uncovering the mechanisms by which we shape plant associated microbiomes yields within stressful environments. Through rhizodeposits, plants influence composition of microbial communities conditions rhizosphere, potentially generating plant-soil feedbacks nutrient availability competitive ability against neighboring plants. Invasive have repeatedly been shown drive that their adapt a wide range environmental suppress Using invasive as model species, discuss what currently known about generate productivity, ability, resilience. Specifically, potential enhanced through 1) positive direct feedback loops occur mutualistic associations; or 2) negative indirect loops, when affect heterospecific either allelopathy, disruption associations, increased pathogen abundance. Knowledge on exudate-microbe interactions may cropping system breeding superior genotypes, amendments disrupt weed-microbe interactions. We argue because native community often evolve response focusing efforts feedbacks, such those associations are likely lead long-term stress resilient crops. Future research should explore extent upregulating production specific exudates non-invasive species same responsible for success.

This study investigates the effects of substrate composition on root architecture, plant growth, and allelopathic secondary metabolites, specifically benzoxazinoids (BXs), in rhizospheres rye (Secale cereale L.) redroot pigweed (Amaranthus retroflexus L.). Given complexities exudate analysis, including influence morphology exudation, experiment compared growth BX release two substrates: glass microbeads a mixture clay beads attapulgite. Rye, pigweed, co-cultures were grown under controlled conditions, with shoot parameters measured to assess suitability. Additionally, UPLC-QTOF-MS was used analyze BXs rye–pigweed co-cultures. The results demonstrated that bead attapulgite provided better conditions effective for extraction, making it suitable studying allelopathy environments. findings highlight critical role both development exudates, implications understanding crop–weed interactions allelopathy.
