“…The VIS plants showed a significant reduction in Chlb, total Chl and relative Chl content compared with control plants. This is consistent with the report that the Chlb content decreased in virusinfected apple leaves (Bertamini et al, 2002) and suggests that Chlb was more sensitive than Chla to similar stress conditions, as reported by Palanisamy et al (2009) and Zhang et al (2020). Previous research has suggested that a decrease in the Chl content of infected leaves might reduce P N (Funayama et al, 1997;Sayed, 2003).…”

Strawberry mottle virus (SMoV) and strawberry vein banding virus (SVBV) cause diseases on strawberry plants, but the effect of coinfection of SMoV and SVBV on the growth, development, and defense system of strawberry (Fragaria × ananassa Duchesne) remains unknown. We investigated the effect of SMoV and SVBV coinfection on strawberry cultivar 'Benihope'. The results showed that stem diameter, leaf size, leaf number, relative chlorophyll content, total chlorophyll content, photosynthetic parameters, and stomatal aperture of SMoV and SVBV co-infected strawberry (VIS) plants were in a weaker level than uninfected control plants, indicating that viruses inhibited the growth and photosynthesis of strawberry plants. Furthermore, the initiation of flowering and fruiting stages of VIS plants were delayed by about three weeks compared with the controls, and the fruiting period was shortened, demonstrating that the reproduction of VIS plants was inhibited. Fruit quality was damaged in VIS plants due to a significant increase in fruit firmness and titratable acidity and decrease in total soluble solid content than control fruits. More dead cells and H 2 O 2 accumulated along the veins of VIS leaves, and the content of abscisic acid and catalase activity significantly increased, whereas anthocyanin content was lower than that of control plants. The results demonstrate that SVBV and SMoV coinfection inhibits the growth and development of 'Benihope' strawberry plants, and the plants respond to viruses by regulating stomatal aperture, the accumulation of ABA and antioxidants.To our knowledge, this study contributes information to understand how both viruses impair the strawberry growth and development for the first time.

“…Similarly, previous research indicated how water de cit caused variations in the decrease of fresh and dry biomass in T. aestivum L. (Pour-Aboughadareh et al, 2019) and Tetraena mandavillei L. (Alam et al, 2021). The interaction between Si and mycorrhiza did not cause a substantial difference in licorice biomass production but, contrary to the present study, several studies have shown that Si and mycorrhiza can increase plant biomass in Glycyrrhiza uralensis (Zhang et al, 2020), Arachis hypogaea L. (Patel et al, 2021), and Nicotiana tabacum L. (Begum et al, 2021). This increase in plant biomass supposedly occurs by a higher rate of carbon assimilation and photosynthesis.…”

AimsWater deficit affect agricultural systems negatively globally. This research objective was to mitigate drought detrimental effects on Licorice growth, utilizing biofertilizer and mineral nutrition. Exogenous application of silicon (Si) and arbuscular mycorrhizal fungi (AMF) may help licorice plant cope with drought stress. MethodsAn experiment was designed with two Si solute levels in irrigation water (i.e. 0 (Si0) and 300 mg/L (Si1)), two levels of AMF inoculation (i.e. inoculation with Claroiedoglomus etunicatum (F1) and without inoculation (F0)), and five soil moisture regimes (i.e. 100, 80, 60, 40 and 20% of field capacity (FC). The impacts of Si and AMF were assessed on licorice yield, mineral uptake, antioxidant potential, and secondary metabolites under water-deficit stress. After two months, the plants were harvested and their morphological traits were measured. Root extracts were utilized for secondary metabolites and nutrient determination. ResultsUnder water deficit conditions, there were significant decreases in root length, diameter, and dry weight (DW) (p<0.05), compared to the control. Si and AMF could significantly (p<0.05) enhance root area (47.75-150.64 cm2) under all irrigation levels. Also, Si significantly (p<0.05) increased the level of root colonization in licorice. The maximum glycyrrhizic acid (GA) (26.62 mg/g DW) was achieved by the interaction between Si and AMF in response to 40% FC. A reduction in total flavonoids and phenolics of licorice was observed under severe drought levels; however, the Si and AMF acted to increase sinapic acid (16.46 mg/g DW), and trans ferulic acid (1.11 mg/g DW) in roots. The results indicated that the interaction between Si and AMF positively affected nitrogen (N) and phosphorous (P) concentrations in roots (53.51 and 74.07 %, respectively). At low irrigation levels, the concentrations of P and Si elements increased significantly in the roots. Also, there was an increase in potassium concentration (K) in response to 100, 80, and 40% FC among Si-treated plants (38.5-44.7%). ConclusionsThe exogenous application of Si and AMF showed a synergistic impact on the ability to mitigate the adverse effects of drought stress by improving plant growth and enhancing metabolite accumulation in licorice. These findings bring prospective insight into world water deficit crisis conquering.

“…We showed that silicon application alleviated the negative effects of salt stress to a certain extent with the extent of the mitigating effect depending on the liquorice species. Although some investigations on the effect of silicon on the growth of liquorice under salt stress have been reported [50][51][52] , this is the rst report demonstrating that foliar spray with silicon enhances the salt tolerance of G. uralensis and G. in ata.…”

“…These observations suggest that silicon promotes the biosynthesis of photosynthetic pigments under salt stress. This may be attributed to the notion that silicon alleviates the damage to chloroplast under salt stress 51 , enhances RuBisCo protein expression, and promotes the synthesis of chlorophyll and carotenoids 48 . Similarly, foliar spraying with silicon alleviated the negative effects of salt stress on gas exchange parameters in the two liquorice species (Fig.…”

Silicon effectively alleviates the damage caused by salt stress in plants and can improve plant salt tolerance. However, the details of the mechanism by which silicon improves salt tolerance of liquorice are limited, and the effects of foliar application of silicon on different liquorice species under salt stress are not known. Here, the effects of foliar spray of silicon on the growth, physiological and biochemical characteristics, and ion balance of Glycyrrhiza uralensis Fisch. and Glycyrrhiza inflata Bat. were investigated. High salt stress resulted in the accumulation of a large amount of Na+, decreased photosynthetic pigment content, perturbed ion homeostasis, and eventually inhibited the both liquorice species growth. These effects were more pronounced in G. uralensis, as G. inflata is more salt tolerant than G. uralensis. Foliar spraying of silicon effectively reduced the decomposition of photosynthetic pigments, improved gas exchange parameters, and promoted photosynthesis. It also effectively inhibited lipid peroxidation and electrolyte leakage and enhanced osmotic adjustment of plants. Further, silicon application increased the K+ concentration, reduced Na+ absorption, transport and accumulation in the plants. The protective effects of silicon were more pronounced in G. uralensis than those in G. inflata. In conclusion, silicon reduces Na+ absorption, improves ion balance, and alleviates the negative effects of salt stress in the two liquorice species studied, but the effect is liquorice species-dependent. These findings may inform novel strategies for protecting liquorice plants against salt stress and also provide a theoretical basis for the evaluation of salt tolerance and the scientific cultivation of liquorice.
