A glycosylphosphatidylinositol-anchored protein from Alternaria alternata triggers cell death and negatively modulates immunity responses in chrysanthemum.

Glycosylphosphatidylinositol-anchored protein (GPI-AP) Aa049 works as a key pathogenic factor to assist A. alternata in infecting plants, which is associated with the reactive oxygen species (ROS) pathway. Chrysanthemum black spot disease is a common fungal disease caused by A.

Plant NAC transcription factors in the battle against pathogens.

Background: The NAC transcription factor family, which is recognized as one of the largest plant-specific transcription factor families, comprises numerous members that are widely distributed among various higher plant species and play crucial regulatory roles in plant immunity.

Results: In this paper, we provided a detailed summary of the roles that NAC transcription factors play in plant immunity via plant hormone pathways and reactive oxygen species pathways. In addition, we conducted in-depth investigations into the interactions between NAC transcription factors and pathogen effectors to summarize the mechanism through which they regulate the expression of defense-related genes and ultimately affect plant disease resistance.

A preliminary identification of , a novel restorer gene for CMS-C in maize ( L.).

C-type cytoplasmic male sterility (CMS-C) is widely utilized for hybrid maize seed production. However, genetic mechanisms underlying the fertility restoration are very complicated. At present, there is a divergence on the number of fertility restorer genes in maize inbred line A619 for CMS-C.
