Figure 1
A: Wild-type strain (JY333) carrying the pTN54-Atg8 plasmid was cultured in EMM to
OD600nm = 0.5, and then the cells were washed and transferred into sulfur-free EMM.
Thereafter, the cells were harvested at each time point, and Western blot analysis was
performed. The amount of α-tubulin was used as loading control. B: JY333 (WT) and
Δatg1 strains harboring pTN54-Atg8 were cultured in EMM to OD600nm = 0.5, and then
the cells were washed and transferred into EMM (control) and sulfur-free EMM (-S),
10
respectively. Cells were harvested at each time point, and Western blot analysis was
11
performed. C: Wild-type strain (JY333) carrying the pTN54-Atg8 plasmid was cultured
12
in EMM to OD600nm = 0.5, and then the cells were washed and transferred into
13
sulfur-free EMM. After 24 h, cells were subjected to fluorescence microscopy
14
observation. FM4-64 was employed for vacuole staining.

A: JY333 (WT) and Δecl1.2.3 (Δecls) strains were cultured in EMM to OD600nm = 0.5,
18
and then the cells were washed and transferred into EMM (control), sulfur-free (-S), and
19
nitrogen-free (-N) EMM, respectively. Cells were harvested at each time point, and then
20
Western blot analysis was performed. B: JY333 (WT) and Δecl1.2.3 (Δecls) strains
21
were cultured in EMM to OD600nm = 0.5, and then the cells were washed and transferred
22
into EMM and sulfur-free EMM, respectively. Cells were harvested at each time point,
23
and then real-time PCR analysis was performed. The expression of cdc2+ was used as
24
the quantitative control. The results are represented as the mean of three independent
25
experiments with standard deviation.
