“…We also found a similar trend of SOC increase in soils of mycorrhized rice plants, which showed a stronger correlation of SOC with AMF colonization at 550 ppm ( p < .001) and 700 ppm ( p < .01) of CO 2 levels, represented in (Tables S2 and S3). The current evidence showed that with increased levels of CO 2 concentration, the carbon content in root exudates increased, which might induce the microbial community shift and their activities . This increase in the structural and functional diversity of microbiome is another plausible reason associated with AMF symbiosis, thereby increasing rice yield.…”

Arbuscular mycorrhizal fungi (AMF), particularly the Glomerales group, play a paramount role in plant nutrient uptake, and abiotic and biotic stress management in rice, but recent evidence revealed that elevated CO2 concentration considerably reduces the Glomerales group in soil. In view of this, the present study was initiated to understand the interaction effect of native Glomerales species application in rice plants (cv. Naveen) under elevated CO2 concentrations (400 ± 10, 550 ± 20, and 700 ± 20 ppm) in open‐top chambers. Three different modes of application of the AMF inoculum were evaluated, of which, combined application of AMF at the seedling production and transplanting stages showed increased AMF colonization, which significantly improved grain yield by 25.08% and also increased uptake of phosphorus by 18.2% and nitrogen by 49.5%, as observed at 700‐ppm CO2 concentration. Organic acids secretion in rice root increased in AMF‐inoculated plants exposed to 700‐ppm CO2 concentration. To understand the overall effect of CO2 elevation on AMF interaction with the rice plant, principal component and partial least square regression analysis were performed, which found both positive and negative responses under elevated CO2 concentration.

“…The application of beneficial microbes is a vital alternative to chemical fertilisers and pesticides. In promoting sustainable agriculture and environmental well-being, microbial technology and its applications are becoming more important (Bhattacharyya et al, 2016). introduced the application of diazotrophic rhizobacteria, a plant growth enhancer, on micropropagated oil palms.…”

Staying resilient is probably an understatement for the oil palm industry during the period of 2018. Whilst other sectors such as the electrical and electronics and other manufactured products were experiencing a bullish growth, the export value of palm oil and palm oil-based products was on the decline. This is essentially due to the looming threat of a total ban of palm oil-based biodiesel by the European Union (EU) come 2021 and the higher production from palm oil plantations in Indonesia causing lower demand and oversupply worldwide. In view of the former, Malaysia's export market scene is expected to change in the coming years. Malaysia has since identified several potential new markets in Africa, Central and South Asia. The negative campaigns relating to health, social or environment targeted at the oil palm are not new but the current action led by the West is clearly causing a major dent in the industry. As the most traded commodity, the industry as a whole is constantly subjected to scrutiny with environment being the current key issue warranting the imposition of checks and balances such as the Malaysian Sustainable Palm Oil (MSPO), Indonesian Sustainable Palm Oil (ISPO) and Rountable Sustainable Palm Oil (RSPO) certification. At the same time, every aspect of the research continues to progress further building on prior knowledge arising directly from working on the oil palm or through model systems. Their progress is briefly highlighted in this review. Clearly the main theme of the research from upstream to midstream and finally downstream are basically aligned with and directed towards achieving the Sustainable Development Goals (SDG) by 2030. This would consequently help further improve the perception of oil palm/palm oil in general.

“…Climate change is one of the major challenges that affect the life of the plant found on the earth particularly affecting the photosynthesis, root activity, general morphology and functioning of plant specimens as well as their interactions (P. N. Bhattacharyya et al, 2016). Anthropogenic activities and agriculture have stimulated the production of greenhouse gases (Hunter, 2008).…”

The emission of green house gas in the globe contributes for the occurrence of climate change through changes in temperature, rain fall and climate extremes. Many changes involve microbes that contribute to or amplify human impacts. Since the basic chemistry of Earth's surface is determined by biological activity-especially that of microbes we must look to studies of microbiology to help us understand how and why the Earth is changing and to find solutions for such undesirable changes. Many of related literatures highly indicates climate change threats projected a 50% global temperature increment, yield reduction showing drop of up to 50% from 2050 to 2100. The predicted changes in temperature, precipitation patterns, and CO2 concentrations in the future could significantly impact the fluxes of soil mineral N and N leaching and also consequences of increases in soil salinity and a decrease in the depth of the water table. Literatures also indicate with the change in climate, the insects, pests and diseases are expected to expand their range and may find new and more vulnerable hosts. However different artificial measures were applied for ultimate goal of maximizing productivity and economic returns, an intimate role of microbes for green house reduction, sustainable soil fertility improvement, control of weeds, pest and plant diseases were reported. The reports indicated that a potential microbe called Prochlorococcus and Synechococcus remove about 10 billion tons of carbon from the air each year, a mixture of Bacillus thuringiensis spores as a pesticide, B. thuringiensis accounts for over 90 per cent of the total share of today's bio insecticide market and diazotroph bacteria (Rhizobium, Bradyrhizobium, Sinorhizobium, Frankia) through symbiotic association accounted 79% atmospheric N fixation and showed an efficacy as potent plant growth promoters. The cumulative summary of many literatures ensures the capability of replacing artificial measures with biological control measures for climate change threats.
