Sustained germination-promoting effect of cold atmospheric plasma on spinach seeds.

Cold atmospheric plasma (CAP) irradiation exhibits a sterilizing effect without causing thermal denaturation or leaving behind residual toxicants. CAP also has potential applications in various fields, including agriculture, leading to research efforts in recent years. This study investigated the effects of CAP on the seed germination rate of spinach (Spinacia oleracea), which typically has a low seed germination rate.

Severe ethanol stress induces the preferential synthesis of mitochondrial disaggregase Hsp78 and formation of DUMPs in Saccharomyces cerevisiae.

Severe ethanol stress (>9% v/v) induces pronounced translation repression in yeast cells. However, some proteins, which are exceptionally synthesized even under translation repression, play important roles in ethanol tolerance. These proteins are expected to provide important clues for elucidating the survival strategies of yeast cells under severe ethanol stress.
