“…Additionally, any bioformulation with an increased shelf life with simultaneous actions of biocontrol and biofertilizer activities under field conditions could open the way for technological exploitation and marketing [ 206 , 207 ]. With rice, PGPB bioformulations have been applied to combat bacterial as well as fungal rice pathogens [ 17 , 208 , 209 , 210 , 211 ]. In 2017, P. aeruginosa strain BRp3 has been suggested as a bio-inoculant for Super Basmati rice and showed antagonistic activities against X. oryzae pv.…”

As a major food crop, rice (Oryza sativa) is produced and consumed by nearly 90% of the population in Asia with less than 9% produced outside Asia. Hence, reports on large scale grain losses were alarming and resulted in a heightened awareness on the importance of rice plants’ health and increased interest against phytopathogens in rice. To serve this interest, this review will provide a summary on bacterial rice pathogens, which can potentially be controlled by plant growth-promoting bacteria (PGPB). Additionally, this review highlights PGPB-mediated functional traits, including biocontrol of bacterial rice pathogens and enhancement of rice plant’s growth. Currently, a plethora of recent studies address the use of PGPB to combat bacterial rice pathogens in an attempt to replace existing methods of chemical fertilizers and pesticides that often lead to environmental pollutions. As a tool to combat bacterial rice pathogens, PGPB presented itself as a promising alternative in improving rice plants’ health and simultaneously controlling bacterial rice pathogens in vitro and in the field/greenhouse studies. PGPB, such as Bacillus, Pseudomonas, Enterobacter, Streptomyces, are now very well-known. Applications of PGPB as bioformulations are found to be effective in improving rice productivity and provide an eco-friendly alternative to agroecosystems.

“…In response to stress, several antioxidative enzymes are produced by the plant. Superoxide dismutase (SOD), catalase (CAT), and peroxidases (POX) are among the enzymatic components of antioxidant systems that regulate the homeostasis of ROS within organisms, as reported in wheat [ 95 , 205 ], rice [ 206 ], sorghum [ 77 , 100 , 101 ], pearl millet [ 79 ] and the chickpea [ 6 ]. The non-enzymatic antioxidants include components such as ascorbic acids, α-tocopherol, flavonoid, glutathione, and carotenoids, which efficiently alleviate oxidative damage by reducing ROS activity or by working together with the enzymatic players to achieve efficient antioxidant activity via the utilization of H 2 O 2 [ 207 , 208 , 209 ].…”

“…High temperature stress leads to the production of a group of proteins called heat shock proteins (HSPs), or stress-induced proteins. Plants under stress tend to produce less normal proteins and up-regulate genes associated with HSPs [ 206 ]. About 20 HSPs have been found in plants, and the diversification of these proteins reflects the adaptation or tolerance to heat stress.…”

“…Low molecular weight HSPs, i.e., −18.1 and −17.9, were reported to accumulate in the pea while it was treated for four hours at 42 °C. The changing responses and expressions of the HSPs vary in different phases of development [ 206 ]. HSP90 also showed an increased expression under heat stress in rice and the soybean [ 249 ].…”

Abiotic stresses, including drought, extreme temperatures, salinity, and waterlogging, are the major constraints in crop production. These abiotic stresses are likely to be amplified by climate change with varying temporal and spatial dimensions across the globe. The knowledge about the effects of abiotic stressors on major cereal and legume crops is essential for effective management in unfavorable agro-ecologies. These crops are critical components of cropping systems and the daily diets of millions across the globe. Major cereals like rice, wheat, and maize are highly vulnerable to abiotic stresses, while many grain legumes are grown in abiotic stress-prone areas. Despite extensive investigations, abiotic stress tolerance in crop plants is not fully understood. Current insights into the abiotic stress responses of plants have shown the potential to improve crop tolerance to abiotic stresses. Studies aimed at stress tolerance mechanisms have resulted in the elucidation of traits associated with tolerance in plants, in addition to the molecular control of stress-responsive genes. Some of these studies have paved the way for new opportunities to address the molecular basis of stress responses in plants and identify novel traits and associated genes for the genetic improvement of crop plants. The present review examines the responses of crops under abiotic stresses in terms of changes in morphology, physiology, and biochemistry, focusing on major cereals and legume crops. It also explores emerging opportunities to accelerate our efforts to identify desired traits and genes associated with stress tolerance.
