Drought is one of the most detrimental environmental factors restricting the growth of wheat (Triticum aestivum L.). The investigation of the impact of uniconazole on carbon metabolism in wheat seedlings under drought stress could provide new insights into wheat stress physiology and tolerance. The effects of uniconazole (30 mg L−1) on wheat drought tolerance were investigated via a physiological analysis of the wheat genotypes ‘Wansu 1510’ (WS1510) and ‘Huacheng wheat 1688’ (HC1688) under a 15% polyethylene glycol (PEG) and 30% PEG treatment and a transcriptome analysis of ‘Wansu 1510’ (WS1510) under a 30% PEG treatment. The results revealed that uniconazole significantly increased the leaf relative water content (RWC), reduced plant height, and counteracted the reduction in fresh weight and root length under drought stress. It inhibited the excessive accumulation of reactive oxygen species (ROS) and protected against membrane lipid peroxidation caused by drought stress by regulating superoxide dismutase (SOD) gene expression, enhancing antioxidant enzymes activities, and adjusting the content of osmoregulatory compounds in drought-stressed plants. Furthermore, uniconazole treatment increased chlorophyll (Chl) and carotenoid (Car) contents, inhibited the increase in sucrose concentration, and alleviated the reduction in starch content due to increased sucrose synthase (SS) activity under drought stress. Transcriptome sequencing revealed that uniconazole regulated the expression of genes associated with starch and sucrose metabolism, porphyrin and chlorophyll metabolism, the photosynthetic antenna proteins, carotenoid biosynthesis, and carbon fixation in photosynthetic organisms, which are involved in carbon metabolism processes and photosynthetic pigment production and which regulate the conversion of sucrose and starch under drought stress. Our findings emphasize the importance of exogenous uniconazole in regulating carbon metabolism in wheat.

“…The improvement in growth parameters of rice plant by PGPR and foliar spray with CT might be due to the mechanisms by which they promote plant growth and the ability to produce or change the concentration of plant hormones (Mordukhova et al 1991), a symbiotic N2 fixation (Boddey and Dobereiner 1995), solubilization of mineral phosphate and other nutrients (Goswami et al 2013), and enzymes (Yuda et al 2016). These results are confirmed in rice plant (Hafez et al 2019;Amer et al 2021;Devarajan et al 2021 andAbd El-Mageed et al 2022), Maize plant (Moridi, et al 2019), Okra plant (Baliah and Muthulakshmi 2017), and sugar beet plant (Ghaffari et al 2022).…”

“…This increase has been known as a tolerance mechanism to drought which probably due to the osmotic regulation in plants by organic solutes i.e. proline and soluble sugars (Salehi et al 2016), and this is also reflected in an increase in absorb more sunlight and increase plant growth and yield (Ievinsh 2020;Ghaffari et al 2022). Furthermore, foliar-applied with liquid organic fertilizers (Ji et al 2017), and PGPR (Hafez et al 2019), who showed a substantial potential for improving the biosynthesis of chlorophyll pigments, such as total chlorophyll, stomatal conductance, and relative water content under water stress.…”

During the two growing seasons 2020 and 2021, A field experiment was carried out at Sakha Agricultural Research Station, Kafr El-Sheikh Governorate, Egypt to assess the impact of individual or combination treatments (T1,T2,T3 and T4) of Plant growth promoting rhizobacteria (PGPR) and foliar spray with compost tea (CT) for enhancing vegetative growth, physiological characteristics, nutrient content and soil biological activities as well as yield components of rice plant (Sakha 105) grown under various intervals of irrigation water regime (I1=irrigation every 3 days, I2=irrigation every 6 days, and I3=irrigation every 9 days). Results showed that all different irrigation water intervals accompanied with PGPR + CT treatment gave the highest values of vegetative growth and physiological characteristics during the two seasons. At the flowering stage, leaves K + , K + /Na + (%), Zn, Mn, Fe and Cu (mg Kg -1 ) showed a significant increase when rice plants exposed to I3 T4 treatment, whereas there was a decrease in Na + (%). Similar trend was observed in the microbial communities in the rhizosphere of rice plants. Soil enzymes were noted to increase with the combination treatment (PGPR + CT), at I3 treatment compared to the other treatments, respectively. For yield parameters, irrigation treatments followed the order of I1 > I2 > I3. However, it followed as T4 > T3 > T2 > T1 under soil and foliar spray treatments. Thus, combination treatment under different irrigation water intervals is an efficient way to partially get rid of the effects of drought on growth dynamics of rice.

“…The ability to recycle a wide variety of organic waste into an effective fertilizer abundant in macro‐ and micronutrients without causing soil pollution or degradation has made vermicompost (VC) an attractive option for sustainable agriculture (Arosha & Sarvananda, 2022 ; Ghaffari et al, 2022 ; Makode, 2015 ; Srivastava et al, 2018 ). The presence of VC in soil, through active interactions between earthworm and microorganisms, has long been shown to not only act as a soil conditioner that provides nutrients to plants, reducing the carbon to nitrogen ratio, but also improve soil texture by increasing soil porosity and water holding capacity, thereby reducing tillage and irrigation (Datta et al, 2016 ; Sharma & Garg, 2018 ; Van Groenigen et al, 2019 ).…”

Hydroponics receives considerable attentions due to population expansion, soil pollution, and farmland scarcity. However, one significant problem is that its residual effluents are detrimental to the surrounding ecosystem. There is a dire need to find an organic, alternative, biodegradable substrate. Vermicompost tea (VCT) was investigated on its suitability as a hydroponic substrate to provide both nutritional and microbiological benefits. It was found VCT increased the biomass of maple peas (Pisum sativum var. arvense L.), increased stem length, raised the potassium ion content, and promoted the uptake of nitrogen by the roots. Meanwhile, the microorganisms associated with earthworm guts were detected in the maple peas root system, namely the inter‐rhizosphere of maple peas, including Enterobacteriaceae, Pseudomonadaceae, and Flavobacteriaceae. The presence of these microorganisms in large number indicated the ability for VCT to retain earthworm intestinal microbes via intestinal tract movement, excreting, and other vital activities. In addition, Rhizobia spp., such as Burkholderiaceae and Rhizobiaceae were also identified in VCT. They are critical for legumes as they can form root or stem nodule symbioses to produce growth hormone, vitamins, nitrogen fixation, and protection against plant stress. These findings are consistent with our chemical analysis that VCT‐treated maple peas had increased nitrate and ammonium nitrogen content relative to the control in roots, stems, and leaves, hence increasing maple peas' biomass. The abundance and species of the inter‐root bacterial population were found to change during the experimental period, indicating the importance of microbial balance to the growth and nutrient uptake of maple peas.
