Soil-Plant-Microbe Interactions in Stressed Agriculture Management:A Review

Pedosphere 2017年第2期27卷 177-192页

作者： Shobhit Raj VIMAL Jay Shankar SINGH naveen kumar arora Surendra SINGH Department of Environmental Microbiology Babashaeb Bhimrao Ambedkar (Central) University Lucknow 226025 (India) Department of Botany Banaras Hindu University Varanasi 221005 (India)

The expected rise in temperature and decreased precipitation owing to climate change and unabated anthropogenic activities add complexity and uncertainty to agro-industry. The impact of soil nutrient imbalance, mismanaged use of chemicals, high temperature, flood or drought, soil salinity, and heavy metal pollutions, with regard to food security, is increasingly being explored worldwide. This review describes the role of soil-plant-microbe interactions along with organic manure in solving stressed agriculture problems. Beneficial microbes associated with plants are known to stimulate plant growth and enhance plant resistance to biotic （diseases） and abiotic （salinity, drought, pollutions, etc.） stresses. The plant growth-promoting rhizobemteria （PGPR） and mycorrhizae, a key component of soil microbiota, could play vital roles in the maintenance of plant fitness and soil health under stressed environments. The application of organic manure as a soil conditioner to stressed soils along with suitable microbial strains could further enhance the plant-microbe associations and increase the crop yield. A combination of plant, stress-tolerant microbe, and organic amendment represents the tripartite association to offer a favourable environment to the proliferation of beneficial rhizosphere microbes that in turn enhance the plant growth performance in disturbed agro-ecosystem. Agriculture land use patterns with the proper exploitation of plant-microbe associations, with compatible beneficial microbial agents, could be one of the most effective strategies in the management of the concerned agriculture lands owing to climate change resilience. However, the association of such microbes with plants for stressed agriculture management still needs to be explored in greater depth.

AIM： To study whether CCR5△32 mutation was associated with viral infection and severity of liver disease. METHODS： Two hundred and fifty two histologically proven, chronic HCV patients （mean age： 41±14 years; M/F： 164/88） were genotyped. PCR based genotyping of 32 bp deletion at the CCR5 locus was done. Fourhundred and eight matched healthy controls were studied to assess susceptibility to HCV infection. To assess correlation of immune gene polymorphism with severity of HCV related liver disease, patients with chronic HCV infection were divided into those with a fibrosis score of ≤ 2 （mild） or 〉 2 （severe） and histological activity index （HAI） of ≤ 5 or 〉 5. For correlation between CCR5△32 mutations and response to therapy, 129 patients who completed therapy were evaluated. RESULTS： The majority （89.4%） of the patients were infected with genotype 3. The frequency of homozygous CCR5△32 mutants was comparable to HCV patients as compared to the healthy controls （0.7% vs 0%, P = 0.1）. Further more, the frequency of CCR5△32 mutation was comparable in patients with mild or severe liver disease.（P = NS）. There was also no association observed with response to therapy and CCR5△32 mutation. CONCLUSION： CCR5△32 mutation does not have a role in disease susceptibility, severity or response to therapy in patients with chronic hepatitis C infection.
