Summary: In this study, a salt-tolerant strain of Trichoderma longibrachiatum HL167 was isolated and found to have inhibitory effects on Fusarium oxysporum under salt stress. It was also observed that HL167 can penetrate and break the hyphae of F. oxysporum. Furthermore, when applied to cowpea plants, HL167 reduced ROS accumulation, alleviated salt damage, improved K+/Na+ ratio, and effectively colonized cowpea roots, leading to successful prevention and control of cowpea Fusarium wilt.

Summary: Food security relies on plant productivity and resilience to climate change, which can be enhanced by silicon's regulation of various mechanisms in plants. Silicon aids in improving plant growth productivity, alleviating biotic and abiotic stress conditions, and plays a role in osmotic adjustment, metabolic processes, and phytohormones. Further research on silicon transporters and regulatory genes is needed for better understanding and application in different stress conditions.

Summary: In recent years, there has been concern about the harmful effects of environmental pollutants on agricultural output. This study investigated the effectiveness of soil application of bulk silicon, silicon nanoparticles, and Trichoderma metabolites in managing abiotic stress (Cd toxicity) and biotic stress (bacterial wilt) in tomato plants. The results showed that the combination treatment of silicon nanoparticles and Trichoderma metabolites, followed by silicon nanoparticles alone, were the most effective in mitigating Cd toxicity and reducing bacterial wilt disease.

Summary: O-methyltransferases (OMTs) in Gossypium species play important roles in phenolics and flavonoid pathways, defending cellulose fiber and promoting plant cell wall strength and growth. Analysis of a 192-member OMT gene family in G. hirsutum, G. arboreum, and G. raimondii reveals their involvement in growth, development, defense against stresses, and their correlations with fiber quality and salt stress response. Specific OMT genes show responses to salt stress and fiber development stages, suggesting their potential contributions to salt tolerance and fiber quality formation in Gossypium.

Summary: bZIP transcription factors play important regulatory roles in plant growth and stress responses. The study classified 132 bZIP genes in the tobacco genome into 11 groups and identified segmental duplications as crucial for gene family expansion. Expression analysis showed differential expression of NtbZIP genes in various tissues and stresses, with NtbZIP62 responding strongly to salinity stress and enhancing salt tolerance when overexpressed. This research provides valuable insights for future functional analyses of bZIP genes in tobacco.

Summary: Rice, one of the most important commodities and a primary food source worldwide, can be affected by adverse environmental factors. In this study, a salt-tolerant chromosome segment substitution line of rice was identified and its transcriptomic data was compared under normal and salt stress conditions. Several BTB genes were found to be differentially expressed under salt stress, with one gene being differentially expressed at the seedling stage and others at the booting stage. Further analysis revealed that OsBTBZ1 plays an important role in transcriptional regulation and is closely associated with other abiotic stress-related proteins. Additionally, OsBTBZ1 was found to function in ABA-dependent pathways for salt tolerance.

Summary: The Diptera are considered one of the most serious arthropod pests affecting mushroom crops, with the Phorid flies, especially Megaselia halterata, being a significant problem on Spanish mushroom farms. Concerns regarding Phorid fly populations have recently increased in countries such as India, the UK, and the USA, where they have transitioned from minor to major pests with reported yield losses ranging from 10% to 40%. Available literature on Phorid populations highlights their natural and seasonal distribution, biology within growing substrates, initial sources of infestation on mushroom farms, as well as the limited control tools and alternative methods to chemical products.

Summary: This study reviewed and quantitatively analyzed plant quality and survival prediction tools, focusing on the Dickson Quality Index (DQI) as a key plant quality parameter. The number of publications using DQI as a plant quality indicator has increased by 150% in the last decade, with Brazilian researchers being the most frequent users. Forestry is the discipline that most commonly uses quality parameters to facilitate intensive plant production, and the use of DQI improves prediction, selection, and productivity in the plant production chain.

Summary: This study summarizes the monitoring of phorid populations at three mushroom farms in Spain over a period of 18 months. The results show that the populations peak in spring and autumn, with a decrease in winter. The study also reveals a positive correlation between accumulated rainfall and the number of phorid adults trapped. The increase in phorids during harvesting suggests the importance of steaming-off the substrates before disposal to prevent fly invasions.

Summary: Wet bubble disease (WBD) is a major problem in mushroom crops worldwide. This study evaluated the effectiveness of different chemical and Bacillus-based products for controlling WBD. Six trials with varying inoculum rates were conducted, and the impact on mushroom productivity and disease incidence was assessed. Chemical fungicides, particularly prochloraz-Mn, showed the greatest reduction in disease incidence. However, bio-fungicides had low efficacy in controlling this mushroom disease at the evaluated doses and timing.

Summary: The aim of this study was to evaluate the effectiveness of Trichoderma aggressivum f. europaeum, T. longibrachiatum, Paecilomyces variotii, and T. saturnisporum as biological control agents against diseases caused by P. capsici and P. parasitica in pepper. In vitro and in vivo experiments were conducted to assess their antagonistic activities, and the expression patterns of five defense-related genes were analyzed in leaves. All four BCAs showed significant in vitro antagonistic activity against P. capsici and P. parasitica. Treatment with T. aggressivum f. europaeum, T. longibrachiatum, and P. variotii effectively reduced disease severity caused by both pathogens, while T. saturnisporum had the lowest effectiveness. Reinoculation with the BCAs improved disease control. The study suggests that these BCAs can be used as an alternative to chemicals to control pepper diseases with high success rates.
