AI Article Synopsis
- This study investigates how cold atmospheric plasma (CAP) affects the structure and biochemical composition of fungal cell walls, which is not well-understood.
- Researchers used atomic force microscopy (AFM) and Fourier transform infrared spectroscopy (FTIR) to analyze changes in cell morphology and composition after treating fungi with Helium-CAP, compared to the drug caspofungin.
- The results showed significant changes in the fungi's surface roughness and shape, along with a decrease in glucans and an increase in chitin production, indicating that CAP alters the fungal cell wall composition.
Article Abstract
(1) Background: Previous studies reported the promising inhibitory effect of cold atmospheric plasma (CAP) on . However, the exact mechanisms of CAP's action on the fungal cell are still poorly understood. This study aims to elucidate the CAP effect on cell wall, by evaluating the alterations on its structure and biochemical composition; (2) Methods: cells treated with Helium-CAP were analyzed by atomic force microscopy (AFM) and Fourier transform infrared spectroscopy (FTIR) in order to detect morphological, topographic and biochemical changes in the fungal cell wall. Cells treated with caspofungin were also analyzed for comparative purposes; (3) Results: Expressive morphological and topographic changes, such as increased roughness and shape modification, were observed in the cells after CAP exposure. The alterations detected were similar to those observed after the treatment with caspofungin. The main biochemical changes occurred in polysaccharides content, and an overall decrease in glucans and an increase in chitin synthesis were detected; (4) Conclusions: Helium-CAP caused morphological and topographic alterations in cells and affected the cell wall polysaccharide content.

Article Synopsis
- The Malvaceae family, the largest in the order Malvales, has nine subfamilies, with many species in the Firmiana genus being globally vulnerable and lacking genomic research.
- A chromosome-level genome assembly for Firmiana hainanensis reveals it has 40 chromosomes and is closely related to Durio zibethinus, diverging around 21 million years ago, with significant events in their evolutionary histories.
- The study highlights how changes in chromosome numbers and genome sizes, particularly influenced by repetitive elements and specific gene contractions, can impact traits like wood density in Malvaceae species.

Article Synopsis
- * Overexpression of MaFLA27 led to increased expression of genes involved in cell wall components and modification, contributing to thicker cell walls and higher levels of cellulose, lignin, and certain pectins in plants.
- * In contrast to wild-type plants, MaFLA27-overexpressing plants showed lower levels of pectin methyl-esterification and reduced reactive oxygen species after cold exposure, indicating a potential mechanism for improved cold tolerance linked to cell wall modifications.
