Frontiers | Diversity of common bean rhizobia in blackland of northeastern China and their symbiotic compatibility with two host varieties

Common bean (Phaseolus vulgaris L.) is an important crop in the world that forms root nodules with diverse rhizobia. Aiming to learning the rhizobial communities associated with common bean in the black soil of Northeast China, 79 rhizobia were isolated from root nodules of two host varieties (Cuican and Jiadouwang) grown in two sites of blackland, and were characterized by comparative sequence analyses of 16S rRNA, recA, atpD, nodC, nifH genes and whole genome. As results, Rhizobium indigoferae, R. anhuiense and R. croatiense as minor groups and three dominant novel Rhizobium species were identified based on their ANI and DDH values to the type strains of relative species. This community composition of rhizobia associated with common bean in the tested black soils was unique. Despite their different species affiliation, all of them were identified into the symbiovar phaseoli according to the phylogenies of symbiotic genes (nodC and nifH). While the discrepancies found in nodC and nifH

Frontiers | Restoration of Degraded Grassland Significantly Improves Water Storage in Alpine Grasslands in the Qinghai-Tibet Plateau

Alpine grassland has very important water conservation function. Grassland degradation seriously affects the water conservation function, moreover, there is little understanding of the change of water state during grassland restoration. Our study aims to bridge this gap and improve our understanding of changes in soil moisture during the restoration process. In this study, the water storage, vegetation, and meteorology of a non-degradation grassland (grazing intensity of 7.5 sheep/ha) and a severely degraded grassland (grazing intensity of 12-18 sheep/ha) were monitored in the Qinghai-Tibet Plateau for seven consecutive years. We used correlation, stepwise regression, and the boosted regression trees (BRT) model analyses, five environmental factors were considered to be the most important factors affecting water storage. The severely degraded grassland recovered by light grazing treatment for seven years, with increases in biomass, litter, and vegetation cover, and a soil-water storage
