Black pepper ( Piper nigrum L.), a highly valued spice crop, is economically significant as one of the most widely traded spices in world. The global yield and quality black L.) are affected by foot rot-causing soil-borne oomycete pathogen Phytophthora capsici . To gain initial insights toward developing an approach that utilizes microbial genetic resources for controlling rot disease pepper, we mapped rhizobiome communities susceptible L. wild-resistant colubrinum analysis showed compositional differences two species, which revealed higher diversity presence more differentially abundant genera P. Furthermore, had significantly abundance known anti-oomycete genera, such Pseudomonas , differential Janthinobacterium Variovorax Comamonas indicating their probable contribution to resistance. Predictive functional profiling enriched gene orthologs (KOs), particularly chemotaxis proteins, osmoprotectants, other transport systems aid Similarly, pathways phenylpropanoid biosynthesis antimicrobial synthesis were rhizobiome. culturable resistant root endosphere, harbors efficient biocontrol agents strengthens possible role microbiome conferring resistance against pathogens. Our results depicted clear distinction architecture spp., suggesting its influence recruiting bacterial probably contribute

In a plant-microbe symbiosis, the host plant plays key role in promoting association of beneficial microbes and maintaining microbiome homeostasis through microbe-associated molecular patterns (MAMPs). The associated provide an additional layer protection for immunity help nutrient acquisition. Despite identical MAMPs pathogens commensals, distinguishes between them promotes enrichment ones while defending against pathogens. rhizosphere is narrow zone soil surrounding living roots. Hence, various biotic abiotic factors are involved shaping responsible pathogen suppression. Efforts have been devoted to modifying composition structure microbiome. Nevertheless, systemic manipulation has challenging, predicting resultant after introduced change difficult. This due involvement that determine assembly result increased complexity microbial networks. Thus, comprehensive analysis critical influence will enable scientists design intervention techniques reshape functions systematically. this review, we give highlights on fundamental concepts suppressiveness concisely explore studies how plants monitor homeostasis. We then emphasize govern pathogen-suppressive assembly. discuss infection enhances by employing cry-for-help strategy examine domestication wipes out defensive genes experiencing syndrome. Additionally, insights into availability pH suppression rhizosphere. finally highlight up-to-date endeavors gain valuable potential strategies which could be reshaped promote development.
