Study on Phyllosphere Microbial Community of Nettle Leaf during Different Seasons

Nettle (Urtica cannabina) is an excellent feed resource widely distributed worldwide. Phyllosphere microbes are important as they have living conditions similar to those of the above-ground parts host plants. Exploring amino acids (AA) and microorganisms can further understand growth plants in different seasons. The present study investigated content AA phyllosphere microbes’ structure nettle results found that contents varied significantly with season, such alanine, aspartate, cysteine, glutamate, glycine, methionine decreased from spring winter (p < 0.05), arginine, histidine, serine, lysine were highest summer 0.05). suggested diversity bacteria fungi both increased during winter. During winter, Sphingomonas (relative abundance 25.22–28.45%) Filobasidum (27.6–41.14%) became dominant. According redundancy analysis (RDA) correlation between microbes, these two most factors showed a negative Thus, seasons could affect distribution microbial communities on nettle, especially function prediction(PICRUS2 (KEGG pathway) FUNGuild) results, U. cannabina mainly participated metabolism. Pathogenic relatively high autumn. reveals influence seasonal change community cannabina.
