“…In the meta-analysis process, if the effect sizes of seaweed fertilizer application (regardless the crops types, using method or locations et al) were not distributed normally, the sampling method option ‘bootstrapping (resampling nonparametric estimation method)’ should be selected [ 36 ]. To test the normality of the seaweed fertilizer effect size in this study, we calculated the seaweed fertilizer effect size distribution frequency and fitted them with gaussian function in SPSS 25.0 statistics software (IBM SPSS, Inc, Armonk, NY, USA).…”

Seaweed fertilizer, formulated primarily with seaweed extract as its main ingredient, has been extensively studied and found to significantly improve nutrient use efficiency, increase crop yield and quality, and enhance soil properties under field conditions. This growing body of evidence shows that seaweed fertilizer is a suitable option for sustainable agriculture in China. However, a comprehensive and quantitative analysis of the overall effects of seaweed fertilizer application in China is lacking. To address this gap, we conducted a meta-analysis of relevant studies on the effects of seaweed fertilizers under field conditions in China with MetaWin and SPSS software. Our analysis examined the effects of seaweed fertilizers on crop yield, quality, and growth under different preparation methods, application techniques, and regions. Our results showed that the application of seaweed fertilizer led to a significant average increase in crop yield of 15.17% compared with the control treatments. Root & tuber crops exhibited the most pronounced response, with a yield boost of 21.19%. Moreover, seaweed fertilizer application significantly improved crop quality, with elevations in the sugar-acid ratio (38.32%) vitamin C (18.07%), starch (19.65%), and protein (11.45%). In addition, plant growth parameters such as height, stem thickness, root weight, and leaf area showed significant enhancement with seaweed fertilizer use. The yield-increasing effect of seaweed fertilizers varied depending on their preparation and use method, climate, and soil of application location. Our study provides fundamental reference data for the efficient and scientific application of seaweed fertilizers in agricultural practices.

“…The growing issue of soil salinization is having a negative impact on plant growth and reducing crop yields on a global scale. Salt stress can significantly hinder plant growth, leading to harmful consequences for agricultural production worldwide ( Hasegawa et al., 2000 ; Yan et al., 2022 ).…”

Increasing biotic and abiotic stresses are seriously impeding the growth and yield of staple crops and threatening global food security. As one of the largest classes of regulators in vascular plants, WRKY transcription factors play critical roles governing flavonoid biosynthesis during stress responses. By binding major W-box cis-elements (TGACCA/T) in target promoters, WRKYs modulate diverse signaling pathways. In this review, we optimized existing WRKY phylogenetic trees by incorporating additional plant species with WRKY proteins implicated in stress tolerance and flavonoid regulation. Based on the improved frameworks and documented results, we aim to deduce unifying themes of distinct WRKY subfamilies governing specific stress responses and flavonoid metabolism. These analyses will generate experimentally testable hypotheses regarding the putative functions of uncharacterized WRKY homologs in tuning flavonoid accumulation to enhance stress resilience.

“…MEL, an indolic compound derived from tryptophan, has an important role in the general processes of plants such as stress relief, germination, circadian rhythms, flowering, photosynthesis and senescence (Rajora et al, 2020). MEL increases tolerance to NaCl stress in two ways, directly (by providing electrons to ROSs) and indirectly (by increasing the activity of antioxidant enzymes, photosynthetic efficiency, metabolite content and regulating stress-related transcription factors) (Ayyaz et al, 2022;Yan et al, 2022). Moreover; Exogenous MEL application can regulate the expression of ion channel genes (NHX1 and AKT1) involved in ion homeostasis in leaf tissue to improve salinity resistance in plants (Li et al, 2019;Rajora et al, 2020).…”

Salinity, an important abiotic stress, affects arable land worldwide, reducing crop growth, yield and quality. Lettuce ( Lactuca sativa L.), which is very sensitive to salt stress, is one of the crops affected by soil salinity and salt (NaCl) stress also affects lettuce cultivation. Different plant growth regulators (salicylic acid (SA), polyamines, glycine betaine (GB) and melatonin (MEL)) are used to reduce the harmful effects of soil salinity. In this study, the effects of NaCl and MEL treatments on physiological parameters (cell membrane damage (%), leaf relative water content (RWC%), chlorophyll amount), DNA methylation and some NaCl tolerance genes ( SOS1, SOS2, AKT1, NHX1, HKT1) have examined in two different lettuce genotypes (Yedikule and Ivanka). When the effect of NaCl stress on physiological parameters was examined, it was detected that this stress increased cell membrane damage and decreased chlorophyll content and RWC %. The effects of MEL applications together with NaCl stress on these parameters were positive. In the gene expression analysis results, it was determined that SOS1, SOS2, AKT1, NHX1 and HKT1 gene expressions increased in both lettuce genotypes and decreased in MEL applications. On the flip side, according to methylation sensitive amplification polymorphism (MSAP) findings, while a decrease in methylation level was determined in NaCl stress compared to the control in both genotypes. Methylation levels increased compared to NaCl stress in MEL applications with NaCl stress, but this rate was still lower than the control. According to the results obtained, it was concluded that exogenous MEL application in lettuce genotypes is important in response to NaCl stress.
