“…Biochemical and molecular factors involved in the induction of processes to ameliorate the negative impacts of water stress include transcription, stress responsive genes ( Table 1 ) and abscisic acid [ 113 ]. Concurrently to the increased tolerance to drought deficits, breeding programs are also interested to kept other stresses under control through transgenic expression of different stress responsive genes [ 114 , 115 ]. However, the increased expression of these genes is frequently associated with a deceleration in the plant growth rate, this could narrow down its practical use.…”

Drought stress, being the inevitable factor that exists in various environments without recognizing borders and no clear warning thereby hampering plant biomass production, quality, and energy. It is the key important environmental stress that occurs due to temperature dynamics, light intensity, and low rainfall. Despite this, its cumulative, not obvious impact and multidimensional nature severely affects the plant morphological, physiological, biochemical and molecular attributes with adverse impact on photosynthetic capacity. Coping with water scarcity, plants evolve various complex resistance and adaptation mechanisms including physiological and biochemical responses, which differ with species level. The sophisticated adaptation mechanisms and regularity network that improves the water stress tolerance and adaptation in plants are briefly discussed. Growth pattern and structural dynamics, reduction in transpiration loss through altering stomatal conductance and distribution, leaf rolling, root to shoot ratio dynamics, root length increment, accumulation of compatible solutes, enhancement in transpiration efficiency, osmotic and hormonal regulation, and delayed senescence are the strategies that are adopted by plants under water deficit. Approaches for drought stress alleviations are breeding strategies, molecular and genomics perspectives with special emphasis on the omics technology alteration i.e., metabolomics, proteomics, genomics, transcriptomics, glyomics and phenomics that improve the stress tolerance in plants. For drought stress induction, seed priming, growth hormones, osmoprotectants, silicon (Si), selenium (Se) and potassium application are worth using under drought stress conditions in plants. In addition, drought adaptation through microbes, hydrogel, nanoparticles applications and metabolic engineering techniques that regulate the antioxidant enzymes activity for adaptation to drought stress in plants, enhancing plant tolerance through maintenance in cell homeostasis and ameliorates the adverse effects of water stress are of great potential in agriculture.

“…Transgenic expression of different stress responsive genes has been also utilized to confer increased tolerance to draught defecits. [77,78]. The increased expression of these genes is frequently associated with a decreased plant growth rate and this could narrow down its practical use (Table 2) [79].…”

Drought can be referred to as a meteorological period without significant rainfall and it is one of such major abiotic stresses that contributes to a huge reduction in crop yield throughout the world. Plant shows a broad range of physiological, morphological, and biochemical changes such as reduced photosynthetic accumulation, altered gene expression, etc. Under the drought stress which ultimately causes reduced growth as well as poor grain yield. Drought stressconditions trigger production of ROS, which disrupts the dynamic balance between ROS production and ROS scavenging systems and its accumulation depends on the intensity as well as duration of water stress, and it varies among species. A plant species that has a better inherited genetic response allowing it to rapidly deploy its antioxidant enzymatic and non-enzymatic defense system, can tolerate drought better than a plant species with a poor antioxidant defense system. Furthermore, enzyme and protein encoding drought specific genes have the ability to enhance drought tolerance. These two enzymatic and genetic engineering strategies are unique and vital tools, which can be used to help alleviate the world’s future problems related to energy, food, and environmental stresses, particularly drought. This chapter attempts to discuss developments in understanding effects of drought stress and underlying mechanisms in plants for its alleviation.

As a class of heat shock proteins (HSP), HSP70 proteins are critical for cell growth and survival in many living organisms. They are essential protein regulators that tend to maintain cell stability through their chaperone functions. The mechanisms that HSP70 proteins develop by interacting with other proteins enable plants to develop an adaptive defense mechanism by participating in abiotic stress responses. HSP70 proteins in the rapidly developing hemp (C. sativa L.) plant in the agricultural and industrial market were studied in this study, and 16 members were identified. The phylogeny, chromosomal location, protein motifs, gene structures, orthologous relationships, 3D protein models, promoter regions, miRNA structures, gene ontology analyses and potential roles of the CsHSP70 proteins were investigated. Furthermore, RT-qPCR analyses were conducted using a publicly available RNAseq data from the hemp plant, whose biochemical reactions were examined under drought stress, and it was found that it played essential regulatory functions.
