Summary: Transcriptional activity of fungal conidia before dormancy plays a crucial role in conidia maturation, fitness, drug resistance, and virulence post-germination. The environmental-specific transcriptional responses can alter conidial content and gene expression, affecting the capabilities of fungal cells after germination. Fungal conidia prepare for the future by synthesizing and storing transcripts according to environmental conditions present before dormancy.

Summary: In this study, the mechanism of Aspergillus flavus conidia germination inhibition by decreased water activity was explored. The impact of low water activity on cell shape and size was analyzed. Transcriptomics and proteomics identified differentially expressed genes and proteins, with dominant pathways involved in nutrient metabolism and translation. Low water activity was found to inhibit conidia germination and influence the expression of genes related to carbohydrate and amino acid metabolism, as well as translation in Aspergillus flavus.

Summary: The aim of this study was to investigate the effect of temperature on colony growth and conidia germination of entomopathogenic fungi. The results showed that the optimal temperature for fungal colony growth was between 15°C and 25°C, with slight variations among different species. Among all the fungi, 25°C was the temperature at which conidia germination was most intense. These findings are important for the application of fungi in integrated pest management programs.

Summary: The agricultural sector is facing the challenge of increasing food production while minimizing the impact on the ecosystem, environment, and human health. In recent decades, frontier technologies have been developed to improve the sustainability of agricultural production systems by reducing synthetic agrochemicals. One potential innovation is the use of natural substances as plant bio-stimulants to enhance nutrient uptake and tolerance to abiotic factors. Nano-technology is also a useful tool for developing effective plant bio-stimulants to boost crop production and achieve food security.

Summary: Papaya has become an important crop in Malaysia, but suffers from serious postharvest losses due to poor handling. To reduce these losses, early diagnosis and identification of postharvest diseases are recommended. Traditional and advanced techniques such as molecular and immunological approaches can be used for disease identification, but biosensors are the optimal choice for field diagnosis due to their effectiveness and user-friendliness. Delaying disease establishment can be achieved by understanding the pathogen's identity.
