“…This fact of accumulation of proteins/amino acids is confirmed in banana by El-Mahdy et al (2018) who reported that the concentration of phenols and proline increased in cultivars 'Grand Naine' and 'Williams' under cold stress. Abiotic stresses induce shift in photosynthetic activities in plant (Marothia et al, 2020).…”

Global production of bananais adversely affected by abiotic stresses, namely, drought, salinity and low temperature which cause changes in morphology, anatomy, physiology and biochemical metabolism in plant. Different banana cultivars respond differently when grown in subtropical regions due to changes in temperature mainly at the time of flowering and fruiting. The subtropical regions persist cold in winter which become a major constraint for proper growth and development of banana. Only few cultivars are identified for cold tolerance. The cold tolerance is a complex phenomenon, involving numbers of interrelated metabolic pathways. With the onset of cold, growth decrease through alteration in the synthesis of metabolites which are regulated by expression of genes and their interactions. Recently, complete genome sequencing, mutation and transgenesis provided deep insight into the complex mechanism of cold tolerance in banana. In this review, efforts are made to compile the findings and to interpret the better application of technologies in understanding the cold tolerance which may assist in banana breeding.

“…Plants are sessile organisms and abiotic stressors, including drought, salt and severe temperatures, must be endured by them [ 3 ]. Stress responses are complex, integrated circuits rather than simple, linear routes, incorporating several pathways, particularly cellular compartments, tissues and interactions with extra cofactors and/or signaling molecules to coordinate a specific response to a given stimulus [ 4 ]. The tissue or organ that is under stress will determine how the plant reacts.…”

In recent years, the global agricultural system has been unfavorably impacted by adverse environmental changes. These changes in the climate, in turn, have altered the abiotic conditions of plants, affecting plant growth, physiology and production. Abiotic stress in plants is one of the main obstacles to global agricultural production and food security. Therefore, there is a need for the development of novel approaches to overcome these problems and achieve sustainability. Nanotechnology has emerged as one such novel approach to improve crop production, through the utilization of nanoscale products, such as nanofertilizer, nanofungicides, nanoherbicides and nanopesticides. Their ability to cross cellular barriers makes nanoparticles suitable for their application in agriculture. Since they are easily soluble, smaller, and effective for uptake by plants, nanoparticles are widely used as a modern agricultural tool. The implementation of nanoparticles has been found to be effective in improving the qualitative and quantitative aspects of crop production under various biotic and abiotic stress conditions. This review discusses various abiotic stresses to which plants are susceptible and highlights the importance of the application of nanoparticles in combating abiotic stress, in addition to the major physiological, biochemical and molecular-induced changes that can help plants tolerate stress conditions. It also addresses the potential environmental and health impacts as a result of the extensive use of nanoparticles.

“…Plants affected by these abiotic stresses have evolved several morphological, physiological, and molecular responses (Körner, 2003). Regarding physiological defensive strategies, a combination of elements allows plants to avoid and/or tolerate damages produced by these abiotic stresses (Banerjee & Roychoudhury, 2019; Germino & Smith, 2000; Marothia et al, 2020). One of the processes highly affected is photosynthesis (Gururani et al, 2015), a key biological process that determines growth and development, and ultimately the vigor of plants at every development stage.…”

High‐mountain plants must withstand high solar irradiation and low temperatures during winter. Furthermore, climate change is increasing drought events, which pose an additional threat to plants. Here, we studied the stress tolerance mechanisms at various levels of biological organization in English plantain (Plantago lanceolata L.), focusing on photoprotective and antioxidant responses. The response of populations from three different altitudes in the Eastern Pyrenees (1030, 1380, and 1660 m. a.s.l.) was compared during both autumn and winter. Results showed that plants not only suffered from photoinhibition due to very low temperatures at the highest elevation during winter, but also from mild drought stress at the lowest altitude during autumn. Individuals growing at the highest elevation showed reductions in the maximum photochemical efficiency of PSII (Fv/Fm ratio), which might be caused by the lack of an increased induction of tolerance mechanisms at the highest elevation compared to the intermediate one. Although most leaves died at the highest elevation, plants could withstand stress at the organism level by generating new leaves once the stress ceased. Drought at the lowest elevation during autumn caused mild stress with small decreases in the Fv/Fm ratio, along with an increase in abscisic acid and jasmonic acid content. This study underlines the great capacity of English plantain to adapt to high elevation by activating not only photo‐ and antioxidant protection mechanisms and adjustments in stress‐related phytohormones, but also by fully regenerating its aboveground biomass through renewed growth once the stress has ceased.
