The objective was to analyze the antioxidants in relation to nutrition, stomatal density, and the yield of cilantro nourished with CLPW. The methodology was based on an applied experimental approach, so the statistical model of completely randomized block design was employed, which consisted of 3 blocks and 5 treatments: T1 with 0, T2 with 2, T3 with 3, T4 with 4, and T5 with 5 liters of CLPW per 200 liters of water. The doses were applied 15 and 30 days after planting. The data obtained from the physical characteristics of cilantro, such as total length, plant weight, number of leaves, and commercial yield, were processed using analysis of variance and the Duncan test. Additionally, the concentration of nutrients (nitrogen, potassium, phosphorus, calcium, magnesium, sulfur, molybdenum, iron, manganese, copper, zinc, boron, chlorides, and sodium), antioxidant capacity, stomatal density in leaves, and profitability were evaluated. The results determined that T5 stood out in total length with 55.23 cm, plant weight with 79.63 g, number of leaves with 162, and commercial yield with 27.017 t/ha.

In response to this challenge, the current study investigates the effects of over-expressing the ICE1 gene in rice plants on cold tolerance. Through constructing the pCAMBIA3301-ICE1 vector, transgenic rice lines with increased ICE1 expression were generated and investigated for their response to chilling stress. Upon subjecting the transgenic rice plants to chilling stress conditions, notable improvements were observed compared to wild-type (WT) plants. Specifically, the transgenic lines exhibited a substantial 62% reduction in visual damage severity, highlighting their enhanced resilience to cold-induced damage. Additionally, the transgenic lines showed a significant 30% increase in proline concentrations, indicative of enhanced stress tolerance mechanisms. Further analyses revealed a 50% reduction in malondialdehyde (MDA) levels and a 38% increase in peroxidase (POX) activity in the transgenic rice plants compared to the WT plants. These findings suggest improved antioxidant defense mechanisms and reduced oxidative damage, contributing to the overall cold stress tolerance of the transgenic lines. Interestingly, differential expression patterns of the ICE1 gene were observed between the leaves and roots of the transgenic plants under cold stress. Roots consistently exhibited higher levels of ICE1 expression, highlighting potential organ-specific responses to cold stress.

It should be noted that in the biofertilizer formula, the strains A. chroococcum and P. polymyxa are unaltered components, and the nodule bacteria are included depending on the type of crop, taking into account the specificity of these bacteria to plants. In this case, both the nitrogen-fixing capacity and the phosphate-mobilizing activity of these bacteria were taken into account. It was found that the increase in the organic layer content from 2.73 to 5.79% occurs with the active participation of microbial strains introduced into the soil. During the plant growth period, an increase in mobile nitrogen forms (NO3-) to 71.9 mg-eq/100 g and soil saturation with molecular nitrogen to 16.2 mg/100 g were detected. A decrease in the content of phosphorus salts (Р2О5, РО43-) and potassium (K+) to 2.86, 3.82 and 5.86 mg-eq/100 g, respectively, was shown. Thus, the content of the immobile form of potassium (K2O) decreases approximately 3 times, and the amount of immobile phosphorus (P2O5) - 3.63 times. These processes in the soil are due to the active activity of nitrogen-fixing and phosphate-solubilizing bacteria, as well as the use of these ions by plants. At the same time, the nitrogen (N) content increases by 2.38 times, and its mineralized form - NO3- by 3.0 times, respectively. As a result of the field experiments, it was found that the tested soil rhizobacteria actively adhere to seeds and seedlings, spreading in the rhizosphere of plants, contributing to the effective action of the biopreparation, thereby fixing more nitrogen. Microorganisms in the process of metabolism increase the efficiency of obtaining soluble salts of phosphorus, potassium and calcium by plants. In general, it was found that joint inoculation of rhizobacteria strains demonstrated higher growth parameters and plant biomass, and crop ripening is achieved 12-20 days earlier compared to the control options.

Nematodes were found encysted in the intestinal serosa, heart, and fatty tissue. Morphological analysis identified the helminths as L3 larvae of Contracaecum, which was further confirmed by molecular analyses using cytochrome c oxidase subunit 2 (COX II) and large subunit ribosomal RNA (28S) genes. Phylogenetic inferences placed these larvae within a well-supported clade of Neotropical and Panamanian Contracaecum, containing sequences of Contracaecum jorgei (Argentina and Colombia) and other sequences identified as Contracaecum sp. and Contracaecum multipapillatum (Mexico, Costa Rica and Guatemala). Molecular distance analyses suggest that this Neotropical/Panamanian lineage of Contracaecum represents a single species, highlighting the fact that C. multipapillatum is currently non-monophyletic, with divergent lineages distributed across the Nearctic, Palearctic, Oriental, and Neotropical regions. Haplotype analysis supports this hypothesis with evidence of recent speciation events or ongoing gene flow within these Neotropical/Panamanian Contracaecum lineages. This new record of Contracaecum sp. larvae infecting fish in the Pardo River, Brazil, provides valuable insight into the phylogeny of this genus, which is suspected to have zoonotic potential, though no documented human infections have been reported in the Americas.</p>","PeriodicalId":55326,"journal":{"name":"Brazilian Journal of Biology","volume":"85 ","pages":"e290054"},"PeriodicalIF":0.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144610401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
