Summary of "Utilization of carbon sources in the rice rhizosphere and non-rhizosphere soils with different long-term fertilization management."

Carbon (C) is playing an important role in the interaction between plant and rhizosphere microbial community, but there is still limited information about how C source utilization soil microbial structure responds to soil fertility changes under double-cropping rice (Oryza sativa L.) system in Southern of China paddy fields. Therefore, the effects of long-term (33 year) fertilizer regimes on the characteristics of C utilization in both the rhizosphere and non-rhizosphere soils under double-cropping rice fields in Southern of China were investigated by using metagenome sequencing technology. The experiment was begun in 1986, and including five fertilizer treatments: without fertilizer input (CK), chemical fertilizer alone (MF), rice straw residue and chemical fertilizer (RF), 30% organic matter and 70% chemical fertilizer (LOM), and 60% organic matter and 40% chemical fertilizer (HOM). The results showed that the relative abundance of Gemmatimonadetes and Planctomycetia in both the rhizosphere and non-rhizosphere soils were increased by application of rice straw residue and organic manure, whereas the relative abundance of Gammaproteobacteria and Nitrospira were promoted by application of inorganic fertilizers. The largest group of COG categories was "Amino acid transport and metabolism" with 16.46% unigenes, followed by "General function prediction only" (12.23%). Regarding the GO categories, biological process were the largest category (174 949, 46.40%), followed by cellular component (126 766, 33.62%) and molecular function (110 353, 29.26%). The PCoA analysis indicated that different parts of root zone were the most important factor affecting the variation of C source utilization bacteria community, and the different fertilizer treatments were the second important factor affecting the variation of C source utilization bacteria community. As a result, the application of fertilization practices had significantly effects on the abundance and community composition of C source utilization microbes in paddy soils. The results showed that the combined application of rice straw residue or organic manure with chemical fertilizer practices were significantly increases the C source utilization of soil microorganisms in double-cropping rice fields.

Family of gram-negative bacteria that occur in leaf nodules and the rhizosphere of higher plants.

A non-pathogenic species of Pseudomonas that occurs in soil, especially in the RHIZOSPHERE surrounding plant roots, as well as on the leaves of plants. It has anti-fungal and anti-nematode activities and is used in agriculture as a biocontrol agent.

A group of phenotypically similar but genotypically distinct species (genomovars) in the genus BURKHOLDERIA. They are found in water, soil, and the rhizosphere of crop plants. They can act as opportunistic human pathogens and as plant growth promoting and biocontrol agents.
