“…They also enhanced the carbon metabolism and improve the establishment of Glycin max. The increase in plant yield was 24.5% and 17.41% (Hussain et al, 2021). The application of BF also increases the seeds number and oil yield in Brassica napus besides improvement in morphological and physiological attributes in plants (Lally et al 2017).…”

Drought stress is a threat to agriculture which is decreasing the yield of crops and creating a considerable loss. This research focused on the part played by silicon dioxide nanoparticles (SiO 2 NPs), biofertilizers, and nanosilicab on Triticum aestivum under control and drought stress. Nanosilicab enhanced the germination percentage, germination index, and germination vigor index by 23.07%, 14.49% and, 93.10% under control and 14.42%, 10.52%, and 46.15% under drought. In the pot experiment, the soil was treated with 150 mg/kg SiO 2 NPs, 1% biofertilizer and, 1% nanosilicab before sowing. Nanosilicab increased shoot length and root length by 9.39%, 10.76%, 22.41%, 18.76%, 30.58%, and, 21.56% under control and drought stress conditions. It also increased photosynthetic pigments, osmolytes content, relative water content, membrane stability index, phenol, and avonoid content. The increase in antioxidant activity was signi cantly high by the application of nanosilicab i.e. the augmentation in catalase, peroxidase, and superoxide dismutase was 68.65%, 83.69% and, 85.99% respectively. It also increased the indole acetic acid and cytokinin to 22.28% and 14.79% in comparison to control. The improvement in hundred grain weight and grains per spike by the use of nanosilicab was 36.25%, 38.76%, 27.47%, and 22.59% as compared to control. The positive interaction of nanosilicab with the roots of plants in the rhizosphere improved the growth of plants signi cantly and a potential candidate for application on crops. The novelty of this study lies in the formulation of nanosilicab and its role in drought amelioration.

“…Because of the small amounts of Mo required by most plants, Mo application with solid fertilizers at seeding is not always done; therefore, the supply of Mo to field crops may be neglected. The application of small doses of nutrients strategically at specific phenological stages can stimulate carbon metabolism and enhance tolerance to abiotic stresses such as drought stress ( Primavesi, 1978 ; Alexander, 1986 ; Hussain et al, 2021 ; Rodrigues et al, 2021 ). However, gaps remain in the understanding of the effects of supplemental fertilization with micronutrients, especially molybdenum (Mo), on plant metabolism and production under field conditions.…”

Molybdenum Foliar Fertilization Improves Photosynthetic Metabolism and Grain Yields of Field-Grown Soybean and Maize

Foliar fertilization has been used as a supplemental strategy to plant nutrition especially in crops with high yield potential. Applying nutrients in small doses stimulates photosynthesis and increases yield performance. The aim of this study was to evaluate the efficiency of foliar application of molybdenum (Mo) to soybean and maize. The treatments consisted of the presence (+Mo) and absence (-Mo) of supplementation. Plant nutritional status, nitrate reductase (NR) activity, gas exchange parameters, photosynthetic enzyme activity (Rubisco in soybean and maize and PEPcase in maize), total soluble sugar concentration, leaf protein content, shoot dry matter, shoot nitrogen accumulated, number of grains per plant, mass of 100 grains, and grain yield were evaluated. For soybean and maize, application of Mo increased leaf NR activity, nitrogen and protein content, Rubisco activity, net photosynthesis, and grain yield. These results indicate that foliar fertilization with Mo can efficiently enhance nitrogen metabolism and the plant’s response to carbon fixation, resulting in improved crop yields.

“…Previous studies showed that low R/FR proportion conditions had important effects on lignin biosynthesis and metabolism by affecting the activities of phenylalanine ammonia-lyase (PAL), peroxidase (POD), 4-coumarate: CoA ligase (4CL), and cinnamyl alcohol dehydrogenase (CAD; Koyama et al, 2012;Liu et al, 2018a). As expected, downregulation of these enzyme genes could lead to a decrease in total lignin and alter monomeric proportions, damaged xylem and vascular bundles, and reduced stem quality and lodging resistance (Zheng et al, 2017a;Hussain et al, 2021). In addition, downregulation of ferulic acid-5hydroxylase (F5H) and caffeic acid-oxy-methyltransferase (COMT) genes had little effect on total lignin (Lin et al, 2015), but could alter the macromolecular structure and subunit polymerization of lignin, affecting the lignin subunit proportion and thus the breaking strength of the stem (Baucher et al, 2003;Stewart et al, 2009).…”

The low red/far-red (R/FR) light proportion at the base of the high-density wheat population leads to poor stem quality and increases lodging risk. We used Shannong 23 and Shannong 16 as the test materials. By setting three-light quality treatments: normal light (CK), red light (RL), and far-red light (FRL), we irradiated the base internodes of the stem with RL and FRL for 7h. Our results showed that RL irradiation enhanced stem quality, as revealed by increased breaking strength, stem diameter, wall thickness and, dry weight per unit length, and the total amount of lignin and related gene expression increased, at the same time. The composition of lignin subunits was related to the lodging resistance of wheat. The proportion of S+G subunits and H subunits played a key role in wheat lodging resistance. RL could increase the content of S subunits and G subunits and the proportion of S+G subunits, reduce the proportion of H subunits. We described here, to the best of our knowledge, the systematic study of the mechanism involved in the regulation of stem breaking strength by light quality, particularly the effect of light quality on lignin biosynthesis and its relationship with lodging resistance in wheat.
