Different Responses of Soil Bacterial and Fungal Communities in Three Typical Vegetations following Nitrogen Deposition in an Arid Desert

Microorganisms, 2023
The effects of increased nitrogen (N) deposition on desert ecosystems have been extensively studied from a plant community perspective. However, the response of soil microbial communities, which play a crucial role in nutrient cycling, to N inputs and ...

Nitrate uptake and carbon exudation – do plant roots stimulate or inhibit denitrification? [PDF]

, 2020
Background and aims Plant growth affects soil moisture, mineral N and organic C availability in soil, all of which influence denitrification. With increasing plant growth, root exudation may stimulate denitrification, while N uptake restricts ...

The Evolutionary Root of Flowering Plants [PDF]

Systematic Biology, 2012
Correct rooting of the angiosperm radiation is both challenging and necessary for understanding the origins and evolution of physiological and phenotypic traits in flowering plants. The problem is known to be difficult due to the large genetic distance separating flowering plants from other seed plants and the sparse taxon sampling among basal ...

Resistance screening of white yam (Dioscorea rotundata Poir.) accessions against Meloidogyne incognita (Kofoid & White, 1919) Chitwood, 1949 using yam vines

Acta Agriculturae Slovenica, 2022
Root-knot nematode (Meloidogyne incognita) is an economically important phytoparasitic nematode species. In yam production, therefore, breeding for nematode resistance is an important environmentally friendly tool to manage root-knot nematodes damage ...

Radial Oxygen Loss from Plant Roots - Methods [PDF]

, 2021
In flooded soils, an efficient internal aeration system is essential for root growth and plant survival. Roots of many wetland species form barriers to restrict radial O2 loss (ROL) to the rhizosphere.

Alhagi sparsifolia acclimatizes to saline stress by regulating its osmotic, antioxidant, and nitrogen assimilation potential

BMC Plant Biology, 2022
Background Alhagi sparsifolia (Camelthorn) is a leguminous shrub species that dominates the Taklimakan desert’s salty, hyperarid, and infertile landscapes in northwest China. Although this plant can colonize and spread in very saline soils, how it adapts

Ethylene supports colonization of plant roots by the mutualistic fungus Piriformospora indica [PDF]

, 2012
The mutualistic basidiomycete Piriformospora indica colonizes roots of mono- and dicotyledonous plants, and thereby improves plant health and yield. Given the capability of P.
