Cleavage of α-1,4-Glycosidic Linkages by the Glycosylphosphatidylinositol-Anchored α-Amylase AgtA Decreases the Molecular Weight of Cell Wall α-1,3-Glucan in Aspergillus oryzae

This study shows that AoAgtA, a GPI-anchored α-amylase in Aspergillus oryzae, cleaves -1,4-glycosidic bonds in the spacer region of cell wall -1,3-glucan, reducing its molecular weight.

A glycosylphosphatidylinositol-anchored α-amylase encoded by amyD contributes to a decrease in the molecular mass of cell wall α-1,3-glucan in Aspergillus nidulans

The paper investigates the role of AmyD, a GPI-anchored α-amylase, in regulating the molecular mass of -1,3-glucan in Aspergillus nidulans cell walls.

An asexual flower of Silene latifolia and Microbotryum lychnidis-dioicae promoting its sexual-organ development

The paper investigates how infection by Microbotryum lychnidis-dioicae affects sexual-organ development in an asexual mutant of Silene latifolia, finding that stamen suppression is released but gynoecium suppression is not.

Both galactosaminogalactan and α-1,3-glucan contribute to aggregation of Aspergillusoryzae hyphae in liquid culture

This paper identifies galactosaminogalactan and α-1,3-glucan as factors contributing to hyphal aggregation in Aspergillus oryzae and shows that their removal disperses hyphae, improving recombinant protein production.
