“…It occurs when the available water in the soil is reduced to a critical level, affecting the transport of essential mineral nutrients such as potassium, nitrogen, calcium and phosphorus to other parts of the plant. During water deficiency, leaves close their stomata, causing a drop in their conductance, and therefore a decrease of transpiration and photosynthesis activity [2,3]. Salinity stress induces osmotic stress and ion toxicity.…”

“…They play essential roles in different physiological processes including photosynthetic activity, hormonal regulation, nutrient mineralization, metabolism and reproduction [1]. Plant PPs are also vital for the resistance to abiotic stresses [2,3]. In their living habitat, plants are constantly exposed to several constraints such as heavy metals, cold, heat, drought, ultraviolet radiation, salinity, etc., which are detrimental to their productivity [4,5].…”

During the evolution, plants acquired the ability to synthesize different phenylpropanoid compounds like chlorogenic acid (CGA), which plays vital roles in resistance mechanisms to abiotic stresses. These environmental factors, including heavy metal, cold, heat, ultraviolet (UV) light, drought, and salinity affect the plant physiological processes, resulting in massive losses of agriculture production. As plants evolve from green algae to bryophytes, ferns, gymnosperms and angiosperms, phenylpropanoids are produced and accumulated in different tissues, giving the plant the capacity to counteract the harmful effects of the adverse environments. Studies have been performed on the metabolic evolution of rosmarinic acid, flavonoids and lignin, showing that the biosynthesis of phenylpropanoids begins in green algae until the emersion of genes found in angiosperms; however, the evolution of the CGA pathway has not yet been reviewed. We hypothesize that CGA could also be synthesized from algae to angiosperms. In the present review, the evolutionary analysis of CGA pathway and the function of this compound in plant tolerance to abiotic stresses are summarized. Bioinformatics analyzes were carried out on CGA-related genes across 37 plant species and revealed that the metabolic pathway starts in algae and gradually increases until it becomes complete in angiosperms. The key genes exhibited different expression patterns in stress and plant tissues. Interestingly, some genes accumulated rapidly during evolution and were more sensitive to environmental stresses, while others appeared only later in angiosperms. Further studies are needed to better understand the evolution of the CGA metabolic pathway in plants under environmentally stressed conditions.

“…The majority of the studies on the different types of stresses have been carried out individually and under controlled conditions, whereas field studies generally show the effect of the combination of such factors ( Mittler, 2006 ; Suzuki, 2016a ). The combination of two or more types of stress is common in many agricultural areas of the world, causing considerable reductions in crop yields ( Table 1 ; Suzuki et al, 2014 ; Ahmad et al, 2019 ).…”

“…In recent decades, global warming due to climate change has been accelerated by the higher concentration of CO 2 in the atmosphere. This phenomenon is generating an increase in the average temperature, alterations of precipitation patterns, and reduction of arable land and water resources in agricultural areas of the world ( Ahmad et al, 2019 ; Dong et al, 2020 ). Additionally, complex combinations of abiotic stresses such as drought and salinity, salinity and heat, and drought and extreme temperatures due to climate change are expected to occur in many agricultural areas across the globe ( Table 1 ; Suzuki et al, 2014 ; Wijewardene et al, 2020 ).…”

Maize Responses Challenged by Drought, Elevated Daytime Temperature and Arthropod Herbivory Stresses: A Physiological, Biochemical and Molecular View

Maize (Zea mays L.) is one of the main cereals grown around the world. It is used for human and animal nutrition and also as biofuel. However, as a direct consequence of global climate change, increased abiotic and biotic stress events have been reported in different regions of the world, which have become a threat to world maize yields. Drought and heat are environmental stresses that influence the growth, development, and yield processes of maize crops. Plants have developed dynamic responses at the physiological, biochemical, and molecular levels that allow them to escape, avoid and/or tolerate unfavorable environmental conditions. Arthropod herbivory can generate resistance or tolerance responses in plants that are associated with inducible and constitutive defenses. Increases in the frequency and severity of abiotic stress events (drought and heat), as a consequence of climate change, can generate critical variations in plant-insect interactions. However, the behavior of herbivorous arthropods under drought scenarios is not well understood, and this kind of stress may have some positive and negative effects on arthropod populations. The simultaneous appearance of different environmental stresses and biotic factors results in very complex plant responses. In this review, recent information is provided on the physiological, biochemical, and molecular responses of plants to the combination of drought, heat stress, and the effect on some arthropod pests of interest in the maize crop.

“…whereas, biotic stresses include attack by pathogens (bacterial, fungal, viral). Both biotic and abiotic stresses are detrimental to plant growth and development because they are known to cause several metabolic dysfunctions in plants and in extreme cases can also cause death of the plant [1,2]. During the course of evolution, plants have evolved a broad range of defense mechanisms for survival under various stressful conditions.…”

Plants are constantly under the threat of various biotic and abiotic stress conditions and to overcome these stresses, they have evolved multiple mechanisms including systematic accumulation of different phytohormones, phytoalexins and pathogenesis related (PR) proteins. PR proteins are cluster of proteins with low molecular weight which get incited in plants under different stresses. In this paper, in-silico approaches are used to compare the physico-chemical properties of 6 PR proteins (PR1, PR2, PR5, PR9, PR10, PR12) of Arabidopsis thaliana and Oryza sativa. Topological analysis revealed the presence of transmembrane localization of PR2 and absence of transmembrane domain in PR10 of both model plants studied. Amino acid composition shows the dominance of small aliphatic amino acids i.e. alanine, glycine and serine in both plants studied. These results highlights the similarities and differences between PRs of both model plants, which provides clue towards their diversified roles in plants.
