Fruit quality and major metabolites in cold-stored 'Wonhwang' Asian pears are differentially affected by fruit size.

Background: The size of 'Wonhwang' Asian pear fruit may affect fruit quality and physiological disorders differentially during distribution. Thus, this study aimed to evaluate the effect of fruit size on fruit physiological attributes and metabolic responses in terms of soluble carbohydrates and free amino acids in different-sized 'Wonhwang' Asian pears during cold storage and shelf life.

Results: The rate of weight loss and the severity of fruit shriveling were higher in small fruit than in large fruit, while the severity of decay was lower during shelf life.

RgsA Attenuates the PKA Signaling, Stress Response, and Virulence in the Human Opportunistic Pathogen .

The regulator of G-protein signaling (RGS) proteins play an important role in upstream control of heterotrimeric G-protein signaling pathways. In the genome of the human opportunistic pathogenic fungus , six RGS protein-encoding genes are present. To characterize the gene predicted to encode a protein with an RGS domain, we generated an null mutant and observed the phenotypes of the mutant.
