“…The frequency of plant development, photosynthesis, and respiration are disturbed by membrane breakdown due to ROS production. Several cell building materials like carbohydrates, lipids, proteins, and nucleic acid are impaired by ROS in drought stress [ 80 ]. In recent studies, it was observed that Osmo-protectants have been produced under the combined stress conditions of heat and salinity in tomato plants, but do not appear in individual stresses.…”

Agriculture and climate change are internally correlated with each other in various aspects, as climate change is the main cause of biotic and abiotic stresses, which have adverse effects on the agriculture of a region. The land and its agriculture are being affected by climate changes in different ways, e.g., variations in annual rainfall, average temperature, heat waves, modifications in weeds, pests or microbes, global change of atmospheric CO2 or ozone level, and fluctuations in sea level. The threat of varying global climate has greatly driven the attention of scientists, as these variations are imparting negative impact on global crop production and compromising food security worldwide. According to some predicted reports, agriculture is considered the most endangered activity adversely affected by climate changes. To date, food security and ecosystem resilience are the most concerning subjects worldwide. Climate-smart agriculture is the only way to lower the negative impact of climate variations on crop adaptation, before it might affect global crop production drastically. In this review paper, we summarize the causes of climate change, stresses produced due to climate change, impacts on crops, modern breeding technologies, and biotechnological strategies to cope with climate change, in order to develop climate resilient crops. Revolutions in genetic engineering techniques can also aid in overcoming food security issues against extreme environmental conditions, by producing transgenic plants.

“…Plants growing under water deficit conditions face many challenges at the biochemical and molecular level which ultimately causes hindrance to plant’s growth and yield [36,37]. Drought stress causes a decline in photosynthesis by disturbing the mechanism of light harvesting and its utilization, negatively impacting the metabolism of photosynthetic pigments, which declines the RuBisCo function accompanied by disruption of the photosynthetic apparatus [38,39,40].…”

“…Drought stress decreases water potential and the relative water content of plants [47,48,49]. Declined water potential further causes a reduction in the uptake of various essential minerals, such as nitrogen, phosphorous and potassium [37,50]. Water deficit conditions have a negative impact on the nitrogen transporters and nitrogen metabolism.…”

Drought stress adversely effects physiological and biochemical processes of plants, leading to a reduction in plant productivity. Plants try to protect themselves via activation of their internal defense system, but severe drought causes dysfunction of this defense system. The imbalance between generation and scavenging of reactive oxygen species (ROS) leads to oxidative stress. Melatonin, a multifunctional molecule, has the potential to protect plants from the adverse effects of drought stress by enhancing the ROS scavenging efficiency. It helps in protection of photosynthetic apparatus and reduction of drought induced oxidative stress. Melatonin regulates plant processes at a molecular level, which results in providing better resistance against drought stress. In this review, the authors have discussed various physiological and molecular aspects regulated by melatonin in plants under drought conditions, along with their underlying mechanisms.

“…Drought stress adversely modifies many morphological and physiological traits such as plant height, photosynthesis, cell expansion and division, and nutrients uptake (Salehi et al 2016). As soil water potential decreases, plants use the strategy to maintain water capacity for essentially chemical processes through different physiological mechanisms like osmotic regulation, which improves the flow of water from the soil into the roots by accumulating some active ions or organic compounds (Salehi et al 2016;Ahmad et al 2018). It is worth to say that the water deficit is becoming more critical in respect to population growth and global climate change, as the main threats for food security and agricultural sustainability (Cheeseman 2016).…”
