Abstract

Bacteria promote mushroom growth by providing growth factors and vitamins, preventing pathogen growth, and enhancing spore distribution. Soil bacteria involved in the nitrogen cycle showed association with the abundance of ectomycorrhizal fungi. Uncultured microorganisms comprise a significant proportion of complex soil ecosystem. Nanopore sequencing Technologies used a genome-resolved metagenomics approach to evaluate the rhizospheric bacterial diversity of these mushrooms from the tropical forests of West Bengal (India) and the temperate forests of West Kameng districts in Arunachal Pradesh, India. The ectomycorrhizosphere soil of tropical forest has higher abundance of nitrogen fixing bacteria such as Bradyrhizobium diazoefficiens, B. erythrophlei, and B. elkanii whereas the ectomycorrhizosphere soil of temperate forest has higher abundance of Candidatus Solibacter usitatus, Rhodoplanes sp. Z2-YC6860, Candidatus Koribacter versatilis, Bacillus cereus, Granulicella tundricola, G. mallensis, Bradyrhizobium icense, Bradyrhizobium sp. SK17, Acidobacterium capsulatum, Bacillus weihaiensis, Terriglobus saanensis, Planococcus sp. MB-3u-03, Bradyrhizobium sp. CCGE-LA001, and Bradyrhizobium japonicum These microorganisms have deep impact in the growth and development of ectomycorrhizal partners (trees and mushrooms) and be called as mycorrhiza helper bacteria (MHB).

宏基因组学提供了对来自印度热带森林和温带森林的蘑菇根际细菌多样性的见解

细菌通过提供生长因子和维生素、防止病原体生长和增强孢子分布来促进蘑菇生长。参与氮循环的土壤细菌与外生菌根真菌的丰度有关。未经培养的微生物在复杂的土壤生态系统中占很大比例。纳米孔测序技术使用基因组分析的宏基因组学方法来评估这些蘑菇在西孟加拉邦（印度）热带森林和印度印控"阿鲁纳恰尔邦"西卡蒙地区温带森林中的根际细菌多样性。热带森林的外分枝杆菌根际土壤中固氮细菌的丰度较高，如Bradyrhizobium dizoefficiens、B.erythophlei和B.elkanii，而温带森林的外分支杆菌根际土中有较高丰度的Candidatus Solibacter usitatus、Rhodoplanes sp.Z2-YC6860、Candidats Koribacter versatilis、Bacillus cereus、Granulicella tundricola、G.mallensis，冰慢生根瘤菌、慢生根瘤杆菌SK17、荚膜酸杆菌、威海芽孢杆菌、沙氏Terriglobus saanensis、Planococcus sp.MB-3u-03、慢生分枝杆菌CCGE-LA001和日本慢生分枝菌这些微生物对外生菌根伙伴（树木和蘑菇）的生长发育有着深刻的影响，被称为菌根辅助菌（MHB）。

期刊介绍： Ecological Genetics and Genomics publishes ecological studies of broad interest that provide significant insight into ecological interactions or/ and species diversification. New data in these areas are published as research papers, or methods and resource reports that provide novel information on technologies or tools that will be of interest to a broad readership. Complete data sets are shared where appropriate. The journal also provides Reviews, and Perspectives articles, which present commentary on the latest advances published both here and elsewhere, placing such progress in its broader biological context. Topics include: -metagenomics -population genetics/genomics -evolutionary ecology -conservation and molecular adaptation -speciation genetics -environmental and marine genomics -ecological simulation -genomic divergence of organisms
