“…Changes in weather conditions and the emergence of new diseases can have adverse effects on agricultural growth and production (Corwin, 2020). Over the past two decades, newly developed rice varieties that are tolerant to salinity and/or floods have been deployed in affected areas, resulting in remarkable impacts (Bhowmick et al, 2020 ). These varieties have provided opportunities for designing better stress- and variety-specific management options and have given farmers more confidence to invest in input use and good crop husbandry (Imhoff-Kunsch et al, 2019 ; Bhowmick et al, 2020 ).…”

“…Significant capital investment, large-scale adaptations to relevant technologies, and knowledge of know-how have demonstrated positive impacts in managing floods and salt intrusion, and in maximizing the agricultural lands in the potential coastal zone for agri-food production. Site-specific reclamation management strategies such as amendments, irrigation and drainage, and the use of environmental tolerance of planting materials and microbes are the components of climate-smart agriculture that can ensure food security (Jat et al, 2019 ; Bhowmick et al, 2020 ). Figure 1 illustrates the potential application of microbes in food production.…”

As the global human population continues to grow, the demand for food rises accordingly. Unfortunately, anthropogenic activities, climate change, and the release of gases from the utilization of synthetic fertilizers and pesticides are causing detrimental effects on sustainable food production and agroecosystems. Despite these challenges, there remain underutilized opportunities for sustainable food production. This review discusses the advantages and benefits of utilizing microbes in food production. Microbes can be used as alternative food sources to directly supply nutrients for both humans and livestock. Additionally, microbes offer higher flexibility and diversity in facilitating crop productivity and agri-food production. Microbes function as natural nitrogen fixators, mineral solubilizers, nano-mineral synthesizers, and plant growth regulator inducers, all of which promote plant growth. They are also active organisms in degrading organic materials and remediating heavy metals and pollution in soils, as well as soil-water binders. In addition, microbes that occupy the plant rhizosphere release biochemicals that have nontoxic effects on the host and the environment. These biochemicals could act as biocides in controlling agricultural pests, pathogens, and diseases. Therefore, it is important to consider the use of microbes for sustainable food production.

“…Coastal regions are fragile and dynamic with respect to soil characteristics, climatic adversities, and various abiotic stresses such as waterlogging, submergence, and salinity. The tolerance of rice plants to high salinity at the seedling and flowering stages is crucial for the maintenance of its growth and high yield, especially in the coastal rice-growing regions of India ( Bhowmick et al, 2020 ). Improved rice varieties with high yield and enhanced tolerance to abiotic stresses are being developed by cross-breeding and selection from the pool of genetic resources in the cultivated rice.…”

“…IL50-13 was released by the State Variety Release Committee of West Bengal in 2016 for enhancing the production of rice in the coastal saline regions of the state. RPBio4919-50-13 (CN2079) showed a grain yield of 5.07, 5.80, and 5.80 (5.56 t ha-1 pooled) in 2013, 2014, and 2015 at ECe of up to 6 dS m-1 under rainfed shallow lowland situation (30–50 cm water depth) in the wet season ( Bhowmick et al, 2020 ). To understand the genetic basis of high yield in IL50-13 under adverse saline conditions, it was important to sequence its genome along with KMR3.…”

The genomes of an elite rice restorer line KMR3 (salinity-sensitive) and its salinity-tolerant introgression line IL50-13, a popular variety of coastal West Bengal, India, were sequenced. High-quality paired-end reads were obtained for KMR3 (147.6 million) and IL50-13 (131.4 million) with a sequencing coverage of 30X-39X. Scaffolds generated from the pre-assembled contigs of each sequenced genome were mapped separately onto the reference genome of Oryza sativa ssp. japonica cultivar Nipponbare to identify genomic variants in terms of SNPs and InDels. The SNPs and InDels identified for KMR3 and IL50-13 were then compared with each other to identify polymorphic SNPs and InDels unique and common to both the genomes. Functional enrichment analysis of the protein-coding genes with unique InDels identified GO terms involved in protein modification, ubiquitination, deubiquitination, peroxidase activity, and antioxidant activity in IL50-13. Linoleic acid metabolism, circadian rhythm, and alpha-linolenic acid metabolism pathways were enriched in IL50-13. These GO terms and pathways are involved in reducing oxidative damage, thus suggesting their role in stress responses. Sequence analysis of QTL markers or genes known to be associated with grain yield and salinity tolerance showed polymorphism in 20 genes, out of which nine were not previously reported. These candidate genes encoded Nucleotide-binding adaptor shared by APAF-1, R proteins, and CED-4 (NB-ARC) domain-containing protein, cyclase, receptor-like kinase, topoisomerase II-associated protein PAT1 domain-containing protein, ion channel regulatory protein, UNC-93 domain-containing protein, subunit A of the heteromeric ATP-citrate lyase, and three conserved hypothetical genes. Polymorphism was observed in the coding, intron, and untranslated regions of the genes on chromosomes 1, 2, 4, 7, 11, and 12. Genes showing polymorphism between the two genomes were considered as sequence-based new candidates derived from Oryza rufipogon for conferring high yield and salinity tolerance in IL50-13 for further functional studies.
