“…Proline is a stress‐related biomarker known to accumulate in the infected plant parts due to the up‐regulation of their biosynthetic pathway and the inhibition of its degradative pathway (Chhabra et al, 2020). Accumulation of proline seems to serve as a precursor for the biosynthesis of several secondary metabolites and provides some degree of endurance to the plant to survive under stressful conditions (Ghosh et al, 2017).…”

“…Plant infection results in physiological and biochemical alterations in both primary and secondary metabolism that ultimately affect the crop yield. During pathogen attack, plants produce reactive oxygen species (ROS), leading to an oxidative burst that forms the first line of defence against pathogens (Chhabra et al, 2020). Plants possess diverse pre and post‐infection defence mechanisms for restricting the pathogenesis of a disease.…”

Rice (Oryza sativa L.), belonging to the family Poaceae, is the staple food of more than 50% of the world's population. Rice is one of the ancient cereal crops being grown in 117 countries, hence called "Global Grain" (Singh et al., 2019). Over two billion people in Asia derive 80% of their energy needs from rice as a staple food crop (Chaudhary & Tran, 2001). Rice cultivation accounts for 23.3% of gross cropped area in India, accounting for 46% of total cereal production (FAO, 2021). As per the statistical data available, India is

“…Several efforts have earlier been made to characterize and record agronomically valuable information, which constitutes an excellent source of germplasm for future breeding programs (López et al, 2015; Tiwari et al, 2023) because morphological characteristics represent the genetic diversity potential of the crop, which is important for further development of superior genotype (Alhariri et al, 2021; Glaszmann et al, 2010). Importance of different proximate compositions and enzyme activity of leaf, namely, ascorbic acid content, total phenol content, peroxidase and polyphenol oxidase activity in influencing disease reaction in the host plant, has been reported in many crops including okra (Chhabra et al, 2020; Seth et al, 2017; Yadav et al, 2020). The proximate compositions were estimated at periodic intervals to have an understanding about the progress of biochemical activities at different stages of crop growth (Jabeen et al, 2009).…”

Okra, Abelmoschus esculentus (L.) Moench, being highly susceptible to yellow vein mosaic virus (YVMV) disease warrants its genetic improvement for resistance. Applied mutagenesis programme using two optimum doses of gamma radiation, namely, 350 Gy and 450 Gy radiation, was administered for the variety Pusa Sawani rated as excellent for fruit quality but highly susceptible to YVMV disease. Two selected putative mutant families, namely, 350//10///3‐9////28 and 450//66///2‐4////39, isolated in the M5 generation with slightly different plant morphology as compared to the parental genotype, Pusa Sawani, showed consistent resistance against YVMV disease. Upon evaluation in the M6 generation, eight morphological characteristics and five quantitative characteristics differed significantly among the mutants and Pusa Sawani. Proximate compositions and enzyme activity in leaf were significantly higher in the two YVMV‐resistant mutants. Disease screening under artificial inoculation in the insect proof cages confirmed YVMV resistance in these mutants. DNA fingerprinting further validated the alterations occurred in these two isolated mutants compared to the parental genotype. These mutants deserve due attention towards the development of YVMV‐resistant variety.

“…Plant-pathogen interactions are mediated by interplays of multifaceted processes, which are facilitated by the pathogen-and plant-oriented molecules [101,102]. Molecules secreted by pathogens are the main factors, which control their successful penetration, colonization, and pathogenicity inside the host plants [103].…”

Plants host diverse but taxonomically structured communities of microorganisms, called microbiome, which colonize various parts of host plants. Plant-associated microbial communities have been shown to confer multiple beneficial advantages to their host plants, such as nutrient acquisition, growth promotion, pathogen resistance, and environmental stress tolerance. Systematic studies have provided new insights into the economically and ecologically important microbial communities as hubs of core microbiota and revealed their beneficial impacts on the host plants. Microbiome engineering, which can improve the functional capabilities of native microbial species under challenging agricultural ambiance, is an emerging biotechnological strategy to improve crop yield and resilience against variety of environmental constraints of both biotic and abiotic nature. This review highlights the importance of indigenous microbial communities in improving plant health under pathogen-induced stress. Moreover, the potential solutions leading towards commercialization of proficient bioformulations for sustainable and improved crop production are also described.
