“…In contrast to abiotic stress, the accumulation of ABA during biotic stress can either increase plant tolerance or susceptibility (Gietler et al 2020 ). The impact of ABA on plants is also influenced by pathogen type and biotic stress conditions (Bharath et al 2021 ; Rasool 2022 ). High levels of cellular ABA can suppress the immune response of crop plants by repressing salicylic acid activity, making them more susceptible to biotrophic pathogens, such as Magnaporthe oryzae (in barley) and Botrytis cinerea (in tomato), which infect living host cells (Ulferts et al 2015 ; Sivakumaran et al 2016 ).…”

Main conclusion Plant Biomarkers are objective indicators of a plant’s cellular state in response to abiotic and biotic stress factors. They can be explored in crop breeding and engineering to produce stress-tolerant crop species. Abstract Global food production safely and sustainably remains a top priority to feed the ever-growing human population, expected to reach 10 billion by 2050. However, abiotic and biotic stress factors negatively impact food production systems, causing between 70 and 100% reduction in crop yield. Understanding the plant stress responses is critical for developing novel crops that can adapt better to various adverse environmental conditions. Using plant biomarkers as measurable indicators of a plant’s cellular response to external stimuli could serve as early warning signals to detect stresses before severe damage occurs. Plant biomarkers have received considerable attention in the last decade as pre-stress indicators for various economically important food crops. This review discusses some biomarkers associated with abiotic and biotic stress conditions and highlights their importance in developing stress-resilient crops. In addition, we highlighted some factors influencing the expression of biomarkers in crop plants under stress. The information presented in this review would educate plant researchers, breeders, and agronomists on the significance of plant biomarkers in stress biology research, which is essential for improving plant growth and yield toward sustainable food production.

“…Later, research revealed that it may have a part in plant development and plant stress adaptation [13]. ABA is produced in plastids through the methylerythritol phosphate route from carotenoids, a derivative of isopentenyl diphosphate [14][15][16][17]. ABA, often referred to as the "stress hormone," plays a crucial role in regulating multiple processes that enhance a plant's ability to withstand stress.…”

Plant growth regulators (PGRs) are essential for regulating how plants respond to abiotic stress by activating their proliferation and development pathways. Abiotic stressors that plants encounter during their development cycle are attempted to be managed by growth regulators. Growth hormones are chemical messengers that control a plant's regular growth and responsiveness to external stimuli. They control tissue development and differentiation, which controls how quickly plants develop. PGRs are necessary for the plant's reaction to abiotic stress. In addition, hormones in plants allow them to recognize adverse environmental circumstances. The plants' ability to biosynthesize phytohormones allows them to adapt to their environment. Abscisic acid aids plants in dealing with salt and drought stress, whereas ethylene aids plants in salinity, overwatering, cold, and drought. Plants may recover from mechanical damage and drought stress with the help of jasmonic acid. Research has also offered some tips for maximizing the ability of growth regulators to strengthen crops' tolerance to abiotic stressors. ARTICLE HIGHLIGHTS •PGRs play a vital role in helping plants to tolerate abiotic stress. •Research on the use of PGRs to improve crop tolerance to abiotic stress is promising. •PGRs can help plants to tolerate abiotic stress by altering their physiology and morphology. •PGRs have the potential to be used as sustainable tools to mitigate the effects of climate change on agriculture.

“…Plant hormones or phytohormones are biochemicals required for the normal growth and development of plants [1][2][3]. Plant hormones include auxins (IAA), gibberellins (GAs) cytokinins (CK), abscisic acid (ABA), ethylene (ET), besides jasmonates (JA), salicylic acid (SA), brassinosteroids (BR), strigolactones (SL), and nitric oxide (NO).…”

Agricultural productivity world over is threatened by abiotic stress, intensifying food security issues. The plant hormones play a significant role in mitigating abiotic stresses, including drought stress, salinity stress, heat stress, and heavy metal stress, faced by the plants. Considerable research has been conducted to understand hormone-mediated abiotic stress responses in plants and the underlying biosynthetic and regulatory pathways. Deciphering these pathways would allow their manipulation in the laboratory and possible extension to the field. In the present chapter, an overview of the role plant hormones play in mitigating abiotic stress, the underlying mechanisms of their action, and the cross-talk between their signaling pathways to mitigate abiotic stress is presented.
