RESUMEN
Colletotrichum gloeosporioides, a significant fungal pathogen of crops and trees, causes large economic losses worldwide. However, its pathogenic mechanism remains totally unclear. In this study, four Ena ATPases (Exitus natru-type adenosine triphosphatases), homology of yeast Ena proteins, were identified in C. gloeosporioides. Gene deletion mutants of ΔCgena1, ΔCgena2, ΔCgena3, and ΔCgena4 were obtained through the method of gene replacement. First, a subcellular localization pattern indicated that CgEna1 and CgEna4 were localized in the plasma membrane, while the CgEna2 and CgEna3 were distributed in the endoparasitic reticulum. Next, it was found that CgEna1 and CgEna4 were required for sodium accumulation in C. gloeosporioides. CgEna3 was required for extracellular ion stress of sodium and potassium. CgEna1 and CgEna3 were involved in conidial germination, appressorium formation, invasive hyphal development, and full virulence. The mutant of ΔCgena4 was more sensitive to the conditions of high concentrations of ion and the alkaline. Together, these results indicated that CgEna ATPase proteins have distinct roles in sodium accumulation, stress resistance, and full virulence in C. gloeosporioides.
RESUMEN
Inflammation is a double-edged sword. While short-lived, acute inflammation is essential for the repair and resolution of infection and damage, uncontrolled and unresolved chronic inflammation is central to several diseases, including cancer, autoimmune diseases, allergy, metabolic disease, and cardiovascular disease. This report aims to review the literature regarding several members of the nucleotide-binding domain, leucine-rich repeat-containing receptor (NLR) family of pattern recognition sensors/receptors that serve as checkpoints for inflammation. Understanding the negative regulation of inflammation is highly relevant to the development of therapeutics for inflammatory as well as infectious diseases.
