The banana MaFLA27 confers cold tolerance partially through modulating cell wall remodeling.
Int J Biol Macromol
December 2024
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.
Article Synopsis
- This study explores how fruit cracking occurs by analyzing physiological, biochemical, and genetic factors during the ripening process, which affects fruit quality.
- Key findings include the identification of enzyme activities, particularly polygalacturonase and β-galactosidase, as crucial in weakening cell walls, making certain fruit areas more susceptible to cracking.
- The research also highlights significant gene expressions related to cell wall structure and auxin signaling, providing insights for future breeding programs targeting crack-resistant fruit varieties.
Article Synopsis
- Seventeen classical MaAGPs and nine MbAGPs in banana were identified, with a focus on their roles in chilling tolerance, particularly MaAGP1/2/6/9/16/17 likely contributing to this trait.
- The study highlighted the diversity among AGPs and examined their responses to low temperature (LT) stress in both chilling sensitive (CS) and tolerant (CT) banana cultivars, finding key differences in gene expression.
- Results indicated that seven MbAGPs were upregulated in the CT cultivar under LT stress, suggesting these proteins could be important targets for improving chilling tolerance through breeding efforts.
