Plant-associated microbes include taxonomically diverse communities of bacteria, archaebacteria, fungi, and viruses, which establish integral ecological relationships with the host plant and constitute the phyto-microbiome. The phyto-microbiome not only contributes in normal growth and development of plants but also plays a vital role in the maintenance of plant homeostasis during abiotic stress conditions. Owing to its immense metabolic potential, the phyto-microbiome provides the host plant with the capability to mitigate the abiotic stress through various mechanisms like production of antioxidants, plant growth hormones, bioactive compounds, detoxification of harmful chemicals and toxins, sequestration of reactive oxygen species and other free radicals. A deeper understanding of the structure and functions of the phyto-microbiome and the complex mechanisms of phyto-microbiome mediated abiotic stress mitigation would enable its utilization for abiotic stress alleviation of crop plants and development of stress-resistant crops. This review aims at exploring the potential of phyto-microbiome to alleviate drought, heat, salinity and heavy metal stress in crop plants and finding sustainable solutions to enhance the agricultural productivity. The mechanistic insights into the role of phytomicrobiome in imparting abiotic stress tolerance to plants have been summarized, that would be helpful in the development of novel bioinoculants. The high-throughput modern approaches involving candidate gene identification and target gene modification such as genomics, metagenomics, transcriptomics, metabolomics, and phyto-microbiome based genetic engineering have been discussed in wake of the ever-increasing demand of climate resilient crop plants.

“…Arbuscular mycorrhiza (AM) symbiosis being essential for plant nutrition and helps to ensure sustainable yield production [45]. Previous research has shown that AM fungus inoculation can boost plant root activity, which is a comprehensive indication of root nutrient absorption [46]. Furthermore, due to their large mycelia, which effect soil aggregation and absorb nutrients from the soil, AM fungus have been found to enhance soil quality [47].…”

Oil palm plantation sector is the most important contribution to economic growth in most Asian countries and most plantations rely on chemical fertilizer for growth which caused harmful to environment. As we can see, nitrogen in the atmosphere can be fixed by the microorganism through the process of nitrogen fixation where it also can act as a bio-fertilizer. Therefore, three objectives are covered in this study, which 1) to review studies on microbial activities and their interaction with plant in soil, 2) to evaluate the effectiveness of organic matter that enhance microbe activity and also N-fixation and 3) to identify the species of bacteria and fungi used for oil palm inoculation in previous studies. A review of microbial activity has been presented in order to highlight the potential interaction where endophytic BNF bacteria have successfully increase the development of oil palm seedlings. Combination of EFB and cow dung in vermicompost technique showed the higher number of E. eugeniae (32 earthworms) thus increases available plant nitrogen. Microbial inoculation such as Glomus aggregatum, Bacillus salmalaya strain 139SI and Herbaspirillum seropedicae gives positive impact towards growth performance. The findings provided successful significant proof that microbe inoculation has a favorable influence on oil palm FFB production.

“…Previous studies reported that the application of biofertilizers (one constituted by a consortium of bacteria and the other by a consortium of bacteria, fungi, and yeast, integrated with a low rate of chemical fertilizer) led to better palm oil growth, a balanced and sufficient nutrient availability, and help to maintain the survivability of beneficial microorganisms in the soil under greenhouse conditions [64] . Furthermore, Veeramachaneni and Ramachandrudu (2020) [73] demonstrated that bioinoculants, namely Azotobacter chroococcum, Azospirillum brasilense, Bacillus megaterium, Frateuria aurantia, and Glomus aggregatum, enhanced palm oil seedling growth through increased microbial population and enzyme activity in the rhizosphere, allowing to reduce up to 25% the recommended dose of chemical fertilizers.…”

This review put insight into information about biological products used for oil palm production worldwide, particularly in Colombia. Biological products are drawing the next wave of sustainable agriculture in general and palm oil production in particular. The Colombian palm sector is committed to environmentally responsible farming and is a pioneer within America in oil palm certification under roundtable on sustainable palm oil standards. As the global demand for organic food and the awareness of environmental care increases, so does the market for biological products. Biological products help protect oil palm crops against pests and diseases, enhancing plants' growth, health, yield, and profitability. Numerous biological control agents (BCAs) and biofertilizer supplies have been approved and are part of the supply chain for oil palm production. This review offers a comprehensive list of BCAs and biofertilizer supplies commercially available for palm oil production. Thus, it helps cater to the needs of oil palm farmers, agriculturists, and everyone committed to working towards more sustainable oil palm production worldwide.
