AI Article Synopsis
- Ascorbate peroxidase (APX) is crucial for managing reactive oxygen species (ROS) in plants, aiding their growth and stress resistance.
- A study identified 26 APX genes across 13 chromosomes, which were grouped into five branches, revealing varied gene structures and similarities in protein motifs.
- qRT-PCR analysis showed that specific APX genes were highly expressed under stress conditions like high salt, drought, and heat, correlating with increased APX activity, paving the way for more in-depth research on the APX gene family.
Article Abstract
Ascorbate peroxidase (APX) plays an important role in scavenging HO and balancing ROS content in plant cells, which is of great significance for the growth and development of life and resistance to external stress. However, up to now, APXs in () have not been systematically characterized. In this study, a total of 26 genes were identified, which were distributed on 13 chromosomes and divided into five phylogenetic branches. Gene structure analysis showed that they had a wide varied number of exons while BnaAPXs proteins contained more similar motifs in the same phylogenetic branches. qRT-PCR analysis of 26 gene expression patterns showed that three putative cytosol genes , , , two putatice microsomal genes and were up-regulated rapidly and robustly under high salt, water shortage and high temperature stresses. In addition, the above three abiotic stresses led to a significant increase in APX activity. The results provide basic and comprehensive information for further functional characterization of APX gene family in .
