L-phenylalanine in potato onion ( var. G. Don) root exudates mediates neighbor detection and trigger physio-morphological root responses of tomato.

Interaction: Despite numerous recent insights into neighbor detection and belowground plant communication mediated by root exudates, less is known about the specificity and nature of substances within root exudates and the mechanism by which they may act belowground in root-root interactions.

Methods: Here, we used a coculture experiment to study the root length density (RLD) of tomato ( L.) grown with potato onion ( var.

Intercropping with Potato-Onion Enhanced the Soil Microbial Diversity of Tomato.

Intercropping can achieve sustainable agricultural development by increasing plant diversity. In this study, we investigated the effects of tomato monoculture and tomato/potato-onion intercropping systems on tomato seedling growth and changes of soil microbial communities in greenhouse conditions. Results showed that the intercropping with potato-onion increased tomato seedling biomass.

Cucumber ( L.) Seedling Rhizosphere and spp. Communities Altered by Vanillic Acid.

Root exudates mediate soil microbiome composition and diversity, which might further influence plant development and health. Vanillic acid from root exudates is usually referred as autotoxin of cucumber, however, how vanillic acid affect soil microbial community diversities and abundances remains unclear. In this study, vanillic acid (VA; 0.
