“…Drought stress and salinity stress decreased the germination rate and plant growth in various crops ( Farooq et al, 2009 , Awari and Mate, 2015 , Hussain et al, 2016 , Egamberdieva and Jabborova, 2013 ; Egamberdieva et al, 2016 , Egamberdieva et al, 2017 , Jabborova et al, 2020c , Sheteiwy et al, 2021 , Ijaz et al, 2021 ). Similarly, Mueller et al (2019) reported that okra growth and the total dry weight of okra was reduced by drought stress. Water stress reduced the plant growth parameter such as shoot fresh weight, dry weight, leaf number, leaf area, plant height and stem diameter in okra ( Kusvuran 2012 ).…”

“… Maes et al (2009) reported that Jatropha curcas under different water regimes identified anatomical and morphological changes with an increase in adaxial stomatal ratio in response to drought. Drought negatively affects yield in different crops such as okra ( Mueller et al, 2019 , Chaturvedi et al, 2019 , Ranawake et al, 2012 , Haider et al, 2021 ), faba bean ( Li et al, 2018 ) and chickpea ( Pushpavalli et al, 2015 ). The impact of drought stress was studied on plant growth and yield of okra plant by Abdulrahman and Nadir (2018) .…”

Drought is a major abiotic factor limiting plant growth and crop production. There is limited information on effect of interaction between biochar and Arbuscular mycorrhizal fungi (AMF) on okra growth, root morphological traits and soil enzyme activities under drought stress. We studied the influence of biochar and AMF on the growth of Okra ( Abelmoschus esculentus ) in pot experiments in a net house under drought condition. The results showed that the biochar treatment significantly increased plant growth (the plant height by 14.2%, root dry weight by 30.0%) and root morphological traits (projected area by 22.3% and root diameter by 22.7%) under drought stress. In drought stress, biochar treatment significantly enhanced the chlorophyll ‘a’ content by 32.7%, the AMF spore number by 22.8% and the microbial biomass as compared to the control. Plant growth parameters such as plant height, shoot and root dry weights significantly increased by AMF alone, by 16.6%, 21.0% and 40.0% respectively under drought condition. Other plant biometrics viz: the total root length, the root volume, the projected area and root diameter improved significantly with the application of AMF alone by 38.3%, 60.0%,16.8% and 15.9% respectively as compared with control. Compared to the control, AMF treatment alone significantly enhanced the total chlorophyll content by 36.6%, the AMF spore number by 39.0% and the microbial biomass by 29.0% under drought condition. However, the highest values of plant growth parameters (plant height, shoot dry weight, root dry weight) and root morphological traits (the total root length, root volume, projected area, root surface area) were observed in the combined treatment of biochar and AMF treatment viz: 31.9%, 34.2%, 60.0% and 68.6%, 66.6%, 45.5%, 41.8%, respectively compared to the control under drought stress. The nitrogen content, total chlorophyll content and microbial biomass increased over un-inoculated control. The soil enzymes; alkaline phosphatase, dehydrogenase and fluorescein diacetate enzyme activities significantly increased in the combined treatment by 55.8%, 68.7% and 69.5%, respectively as compared to the control under drought stress. We conclude that biochar and AMF together is potentially beneficial for cultivation of okra in drought stress conditions.

“…Plants undergo substantial changes in their physiological and biochemical systems when faced with water deficiency ( Farias et al, 2019 ). Recent studies have shown that under drought conditions, the biomass of okra as well as the uptake of phosphorus in its shoot were both significantly reduced, while nitrogen, potassium, iron, and zinc levels increased in the shoot ( Müller, Eltigani & George, 2019 ). Water deficits affect the physiology and development of okra, and severe water shortages can significantly reduce okra production.…”

The response of okra to drought stress is very complicated, and the molecular mechanisms underlying this process remains ambiguous up to now. In this study, different degrees of water-stress responses of okra leaf were explained by using transcriptomics and metabolomic approaches. The photosynthesis and glycometabolism in okra leaf were both adversely affected by drought stress, leading to inhibition of the carbohydrate metabolic process, and then influencing the secondary plant metabolism. Further, drought stress disturbed amino acid metabolism, especially for the tyrosine-derived pathway as well as arginine and proline metabolism, which have been shown to be significantly enriched under water withholding conditions based on multi-omics conjoint analysis (transcriptome, proteome and metabolome). In-depth analysis of the internal linkages between differentially expressed transcripts, proteins, and metabolites decidedly indicate that tyrosine metabolism could confer tolerance to drought stress by influencing carbon and nitrogen metabolism. These findings provide a whole framework of the regulation and relationships of major transcripts and peptides related to secondary metabolism, particularly, the role of critical proteins and metabolite involved in the change of amino acid metabolism in response to drought stress.
