“…The leap of ABA content provoked by drought stress illustrated in this work has been demonstrated to be one of the early commonly known responses to drought (Imadi et al, 2016). ABA triggers a complex signaling network to regulate stomatal movement (da Silva Folli-Pereira et al, 2016) and plays an important role in drought tolerance in plants (Imadi et al, 2016). Upon TRIA application, ABA level was greatly reduced, yet did not reach the control level; this ABA reduction was also revealed by El-Shafey et al (2018) who showed TRIA-induced ABA decline in maize under drought.…”

Water scarcity and demand for both fresh water and agriculture have overgrown in the last decades, as more than two-thirds of the fresh water in the world are consumed in agriculture (FAO, 2017). About 96% of Egypt's are deserts, leaving only 4% of cultivated lands that are threatened by urbanism and stresses especially drought (Gad, 2020). The frequency and severity of drought events, especially in the Mediterranean basin, have been predicted to increase shortly (Tramblay et al., 2020). Drought has great impacts on the growth, physiology, and biochemistry of several plant species (Jafari et al., 2019), and its effects are expected to exaggerate as global temperature increases. It has been reported that drought stress can directly cause a wide range of injury symptoms in plants, such as limited

“…The researchers suggested that MTP3, MTP7, MTP11, MTP1 , and MTP9 genes are all upregulated in plants under detrimental conditions, e.g. salinity, osmosis, and drought stresses [ 77 ]. Although toxicity with heavy metals can result in similar responses to salinity stress, it may suggest salinity stress results in the storage of excessive ions in plants and decreases the agricultural yields [ 78 , 79 ].…”

Metal tolerance proteins (MTPs) as Me2+/H+(K+) antiporters participate in the transport of divalent cations, leading to heavy metal stress resistance and mineral utilization in plants. In the present study, to obtain better knowledge of the biological functions of the MTPs family, 20 potential EgMTPs genes were identified in Eucalyptus grandis and classified into seven groups belonging to three cation diffusion facilitator groups (Mn-CDFs, Zn/Fe-CDFs, and Zn-CDFs) and seven groups. EgMTP-encoded amino acids ranged from 315 to 884, and most of them contained 4–6 recognized transmembrane domains and were clearly prognosticated to localize into the cell vacuole. Almost all EgMTP genes experienced gene duplication events, in which some might be uniformly distributed in the genome. The numbers of cation efflux and the zinc transporter dimerization domain were highest in EgMTP proteins. The promoter regions of EgMTP genes have different cis-regulatory elements, indicating that the transcription rate of EgMTP genes can be a controlled response to different stimuli in multiple pathways. Our findings provide accurate perception on the role of the predicted miRNAs and the presence of SSR marker in the Eucalyptus genome and clarify their functions in metal tolerance regulation and marker-assisted selection, respectively. Gene expression profiling based on previous RNA-seq data indicates a probable function for EgMTP genes during development and responses to biotic stress. Additionally, the upregulation of EgMTP6, EgMTP5, and EgMTP11.1 to excess Cd2+ and Cu2+ exposure might be responsible for metal translocation from roots to leaves.

“…As leaves with reduced leaf area do not fully intercept solar radiation which in turn strikes the ground, and consequently increased the evaporation -transpiration ratio (Araus, 2002). Reduction in plant height from water deficit stress interferes with over all crop photosynthetic efficiency (Imadi et al, 2016). Hence, plants with greater heights are often larger in overall plant size, intercept more light and use water faster by transpiration.…”

Drought and poor soil fertility are major limitations to crop production, globally. To investigate the impacts of water deficit stress (WS) and soil nutrient amendment (SA) on growth and yield performances of maize. A two years factorial field study was carried out, using a quality protein maize (QPM) (ILE-1-OB) and a non QPM–drought tolerant check (TZPBSR-W) varieties in Ibadan. Treatments include; six fertilizer application rates; 50 and 100 (kg N ha-1) ofNPK-20-10-10, 10.7 kg N ha-1of Tithonia Poultry Compost (TPC), 50 N + 10.7TPC and 100 N + 10.7TPC (kg N ha-1), three WS; the control (FW), WS at vegetative stage (STR1), and WS at reproductive stage (STR2). Leaf area (LA) and grain yield (GY) were measured using standard procedures. From the results, across WS, LA ranged from STR1 (458.90 ± 12.4) to FW (598.81 ± 13.1 cm2), GY varied from STR2 (2.94 ± 0.2 t ha-1) to FW (6.59 ± 0.2 t ha-1), across fertilizers, LA varied from 0 N (397.65 cm2) to 100N + 10.7TPC (622.71 cm2) and 50 N + 10.7TPC (611.03 cm2), respectively. The GY varied from 0 N (2.37 t ha-1) to 100 N + 10.7TPC (5.82 t ha-1) and 50N + 10.7TPC (5.26 t ha-1). Drought stress reduced growth and GY performances of QPM, while SA with 50 kg N ha-1 of inorganic fertilizer and 10.7 kg N ha-1 of TPC enhanced growth and grain yield of maize under WS.
